Which equation is equivalent to y - 6 = -12(x+4)?

Answer:

the answer is 30

Step-by-step explanation:

because it is an equilateral triangle all sides are the same so if you set 3x+15 equal to 7x-5 and solve for x you get 4x=20 and x= 5

when you plug 5 in to each equation you get 30 for both sides and so it proves that the answer is 30

Y=3x+8

Step-by-step explanation:

The slope is 3

Slope Intercept form is Y=Mx=b

We want to write the given equation in the form y = mx + b.

y-5 = 3(x+1)

y - 5 = 3x + 3

y = 3x + 3 + 5

y = 3x + 8

Done!

There are 188 legs in all

Let's solve this problem step by step:

1. First of all, there are 4 unicorns enjoying themselves playing in the forest, they are: Stardust, Umo, Windthorn and Highflyer are enjoying themselves playing in the forest. Each unicorn has 4 legs, so:

[tex]4 \ unicorns \times 4 \ legs=\boxed{16 \ legs}[/tex]

2. The unicorns notice 8 spiders in the tree, so each spider has 8 legs. Accordingly:

[tex]8 \ spider \times 8 \ legs=\boxed{64 \ legs}[/tex]

3. There are 5 cockroaches, so each cockroach has 6 legs. Accordingly:

[tex]5 \ cockroaches \times 6 \ legs=\boxed{30 \ legs}[/tex]

4. There are 7 bees, so each bee has 6 legs. Accordingly:

[tex]7 \ bees \times 6 \ legs=\boxed{42 \ legs}[/tex]

5. There are 3 deer, so each deer has 4 legs. Accordingly:

[tex]3 \ deers \times 4 \ legs=\boxed{12 \ legs}[/tex]

6. There are 4 cows, so each cow has 4 legs. Accordingly:

[tex]4 \ cows \times 4 \ legs=\boxed{16 \ legs}[/tex]

7. They notice a pair of antlers behind a bush, so this means there are 2 more deers, and each having 4 legs. Accordingly:

[tex]2\ deers \times 4 \ legs=\boxed{8 \ legs}[/tex]

7. They notice a pair of antlers behind a bush, so this means there are 2 deers, and each having 4 legs. Accordingly:

[tex]2\ deers \times 4 \ legs=\boxed{8 \ legs}[/tex]

Adding all the amounts of legs we have:

[tex]Total=16+64+30+42+16+12+8=\boxed{188 \ legs}[/tex]

Divide the distance on the map by 2 to get the number of 8km segments there are, then multiply that by 8km for total distance.

16 cm / 2cm = 8

8 x 8km = 64km total.

Answer:

- 2, 64, 0

Step-by-step explanation:

f(- 3) ← x < 0 ⇒ f(- 3) = - 3 + 1 = - 2

f(8) ← x > 0 ⇒ f(8) = 8² = 64

f(0) → x = 0

f(0) = 0² = 0

Answer:

6F

Step-by-step explanation:

Let x be the temperature at noon

dropping means we subtract

The temperature at 9 pm was -4.  That goes on the right hand side of the equals

x-10 = -4

Add 10 to each side

x-10+10 = -4+10

x = 6

The temperature at noon was 6 F

The graph is attached.

To solve the given piecewise function, we need to graph each of the functions that compound the main function with their respective domain restrictions.

So, solving we have:

- First function: Positive slope line (red line).

[tex]f(x)=x+1=y\\\\y=x+1, if x<0[/tex]

Let's find the axis intercepts in order to be able to graph the function.

Finding the x-axis intercept, we need to make "y" equal to 0, so:

[tex]y=x+1\\\\0=x+1\\x=-1[/tex]

So, we have that the x-axis intercept is located at the point (-1,0)

Finding the y-axis intercept, we to mate "x" equal to 0, so:

[tex]y=x+1\\\\y=0+1\\y=1[/tex]

So, we have that the y-axis intercept is located at the point (0,1)

Hence, we have that the function exists from the values of "x" less than 0 to the negative infinite or (-∞,0)

- Second function: Horizontal line (blue line).

[tex]y=2,if0\leq x\leq 1[/tex]

Since there is not variable, we know that it's a horizontal line that passes through y equal to 2.

Hence, we have that the function exists between the values of "x" from  0 to 1 or  [0,1]

- Third function: Positive slope line (green line).

[tex]y=x,ifx>0[/tex]

Let's find the axis intercepts in order to be able to graph the function.

Finding the x-axis intercept, we need to make "y" equal to 0, so:

[tex]0=x+\\\\0=x+\\x=0[/tex]

So, we have that the x-axis intercept is located at the point (0,0)

Finding the y-axis intercept, we to make "x" equal to 0, so:

[tex]y=x\\\\y=0\\y=0[/tex]

We have that the function only pass through the point (0,0) or origin.

Hence, we have that the function exists from the values of "x" greater than 2.

So, the graph of the given function is attached.

The range of a function is the output values ( Y values)

These would be the numbers the arrows are pointing at.

-8, -3 , 5 and 7

The answer is C.

Answer:

all real numbers

Step-by-step explanation:

The range of the function f(x) = (6)x after it has been reflected over the x-axis is the single value y = -6, which represents a horizontal line at that height.

The question asks about the range of the function f(x) = (6)x after it has been reflected over the x-axis. Since f(x) is a constant function, its graph is a horizontal line at the height of y = 6 for any value of x within the domain 0 ≤ x ≤ 20. When this function is reflected over the x-axis, the range becomes the set of values that f(x) takes on after the reflection, which would be a horizontal line at y = -6.

Now, let's formulate what happens after the reflection: If the original range of f(x) is a horizontal line at y = 6, then after reflecting over the x-axis, the new range will be a horizontal line at y = -6. Therefore, the range of the reflected function is the single value y = -6.

Answer:

15 ft

Step-by-step explanation:

Use Pythagorean Thm. If I have two sides:

Then I do this to find the third:

If looking for leg, do sqrt(big square - small square)

If looking for hyp, do sqrt(leg square+leg square)

So what this means since x is a leg, I'm going to do sqrt(17^2-8^2)

17 was bigger than 8 that's why it went first

Anyways now we can just whip out the calculator

sqrt(17^2-8^2)=15

Since this is a right triangle you may use Pythagorean theorem which is [tex]a^{2} +b^{2} =c^{2}[/tex]

a and b are the legs (two sides that FORM the right angle) of the right triangle while c is the hypotenuse (the side that is opposite the right angle)

In this case...

a = x

b = 8

c = 17

Plug these numbers into the formula and solve for x

[tex]x^{2} +8^{2} =17^{2}[/tex]

[tex]x^{2}[/tex] + 64 = 289

[tex]x^{2}[/tex] + (64 - 64) = 289 - 64

[tex]x^{2}[/tex] = 225

To remove the squared from the x take the square root of both sides

x = 15

You are told Y is the number of large vehicles washed and that there were 50 large vehicles.

Replace Y with 50 in the given equation to solve for x ( the number of small cars.

5x + 10(50) = 800

5x + 500 = 800

Subtract 500 from both sides:

5x = 300

Divide both sides by 5:

x = 300/5

x = 60

There were 60 small cars washed.

Final answer:

The correct equation is 3X-3Y = -6, Therefore option A is correct.

Explanation:

To find the correct equation, we can solve the given system of equations. We can do this by using the method of substitution or elimination. Let's use the method of elimination to solve the system.

Multiplying the first equation by 2 and the second equation by 3, we get:

2(x+3y) = 2(-2) ⟶ 2x + 6y = -4

3(2x-6y) = 3(-8) ⟶ 6x - 18y = -24

Adding these two equations together, we eliminate the variable 'x':

(2x + 6y) + (6x - 18y) = -4 + (-24)

8x - 12y = -28

Now, let's compare this equation to the options given. The correct equation is:

3X-3Y = -6

I assume you're talking about 6-7, so on the left lines, you already did it, you just regularly subtract the numbers, and then on the right lines, you round the first problem to the nearest ten, remember five and up, round up, so for question 6 the new number model would be 90-40=50. since 93 rounds down to 90 and 38 rounds up to 40. continue to do that and write the entire model AND answer on the line to the right. hope this helps

Step-by-step explanation:

Answer:

Step-by-step explanation:

Estimate means put your calculator in a drawer or under a pillow. You are not going to use it.

The question means round to the nearest 10 (as it says)

One

93 rounds to 90   (93 is only 3  away from 90)

38 rounds to 40   (38 is very close to 40. You are only 2 away).

90 - 40 = 50

If you answer 55, you should get it wrong. That's not estimating.

Two

67 rounds to 70

49 rounds to 50

70 - 50 = 20        18 is just too exact.

Three

75 is very nasty. My call would be that you can call it 70 or 80. It all depends on what you have been told about 5s. On Brainly, I think you round up. So 75 become 80

27 rounds to 30

80 - 30 = 50  

The last one is all yours.

Answer:

D) x = 40.5

Step-by-step explanation:

When parallel lines create a smaller triangle inside a larger triangle, the triangles are similar. Triangle similarity means that side lengths are proportional, meaning to find x we must use dimensions of the smaller triangle to create a proportion.

The left side of the larger triangle is 12 + 15, so it is 27.

The left side of the smaller triangle is 12.

So, part of the proportion will be [tex]\frac{27}{12}[/tex]

The bottom side of the larger triangle is x.

The bottom side of the smaller triangle is 18.

So, part of the proportion will be [tex]\frac{x}{18}[/tex]

The full proportion will be:

[tex]\frac{27}{12}=\frac{x}{18}[/tex]

Cross multiply and solve for x.

27(18) = 12x

486 = 12x

40.5 = x

[tex]\bf \sqrt{18}~~ \begin{cases} 18=&2\cdot 3\cdot 3\\ &2\cdot 3^2 \end{cases}\implies \sqrt{2\cdot 3^2}\implies 3\sqrt{2}[/tex]

Answer:

[tex]f^{-1}(x)=-3(+/-)\sqrt{\frac{10x+7}{2}}[/tex]

Step-by-step explanation:

we have

[tex]5y+4=(x+3)^{2}+\frac{1}{2}[/tex]

Exchange x for y and y for x

[tex]5x+4=(y+3)^{2}+\frac{1}{2}[/tex]

Isolate the variable y

[tex]5x+4-\frac{1}{2}=(y+3)^{2}[/tex]

[tex]5x+\frac{7}{2}=(y+3)^{2}[/tex]

[tex]\frac{10x+7}{2}=(y+3)^{2}[/tex]

Take square root both sides

[tex](y+3)=(+/-)\sqrt{\frac{10x+7}{2}}[/tex]

[tex]y=-3(+/-)\sqrt{\frac{10x+7}{2}}[/tex]

Let

[tex]f^{-1}(x)=y[/tex]

[tex]f^{-1}(x)=-3(+/-)\sqrt{\frac{10x+7}{2}}[/tex]

Final answer:

To calculate the perimeter of a square with a side length of 5/7 units, multiply the side length by 4 since all sides of a square are equal. The perimeter is 20/7 units.

Explanation:

The question asks, "What is the perimeter of a square with a side length of 5/7 units?" To find the perimeter of a square, we use the formula P = 4a, where P represents the perimeter and a is the length of one side of the square. Since all sides of a square are equal in length, if the side length is 5/7 units, the perimeter would be 4 times 5/7 units.

Performing the multiplication:

P = 4 × (5/7) units

P = (4 × 5) / 7 units

P = 20/7 units

Therefore, the perimeter of the square is 20/7 units.

Answer:

A. [tex]y\le2x^2-8x+3[/tex]

Step-by-step explanation:

The given parabola has vertex at (2,-5).

The equation of this parabola in vertex form is given by:

[tex]y=a(x-h)^2+k[/tex], where (h,k)=(2,-5) is the vertex  of the parabola.

We substitute the values to get:

[tex]y=a(x-2)^2-5[/tex]

The graph passes through; (0,3).

[tex]3=a(0-2)^2-5[/tex]

[tex]\implies 3+5=4a[/tex]

[tex]\implies 8=4a[/tex]

[tex]\implies a=2[/tex]

Hence the equation of the parabola is

[tex]y=2(x-2)^2-5[/tex]

We expand this to get:

[tex]y=2x^2-8x+8-5[/tex]

[tex]y=2x^2-8x+3[/tex]

Since the outward region was shaded, the corresponding inequality is

[tex]y\le2x^2-8x+3[/tex]

Answer:

# The growth value of the function is 1/3 ⇒ 2nd

# f(x) shows exponential decay ⇒ 3rd

# The function is a stretched of the function [tex]f(x)=(\frac{1}{3}) ^{x}[/tex] ⇒ 4th

Step-by-step explanation:

* Lets explain the exponential function

- The form of the exponential function is f(x) = a b^x, where a ≠ 0,

  b > 0 , b ≠ 1, and x is any real number

- a is the initial value of f(x) ⇒ (when x = 0)

- b is the growth factor

- The exponent is x

- If the growth factor (b) is in between 1 and 0 then it is exponential

 decay

* Lets solve the problem

∵ [tex]f(x)=3(\frac{1}{3})^{x}[/tex]

- Lets find the initial value

∵ At the initial position x = 0

∴ [tex]f(0)=3(\frac{1}{3})^{0}=3(1)=3[/tex]

* The initial of f(x) is 3

∵ b = 1/3

∵ b is the growth factor of the function

* The growth value of the function is 1/3

∵ b = 1/3

∵ 0 < b < 1

∴ The function is exponential decay

* f(x) shows exponential decay

- A vertical stretching is the stretching of the graph away from the x-axis

- If k > 1, the graph of y = k•f(x) is the graph of f(x) vertically stretched

∵ [tex]f(x)=(\frac{1}{3})^{x}[/tex]

∵ Its parent function is [tex]f(x)=3(\frac{1}{3})^{x}[/tex]

∴ k = 3

∵ k > 1

∴ the function is stretched vertically

* The function is a stretched of the function [tex]f(x)=(\frac{1}{3})^{x}[/tex]

∴ The true statements are:

# The growth value of the function is 1/3

# f(x) shows exponential decay

# The function is a stretched of the function [tex]f(x)=(\frac{1}{3})^{x}[/tex]
