What’s 1/6 of 2 I’m learning about this and I still don’t get it

ANSWER

[tex]x = 5 \: or \: x = - 5[/tex]

EXPLANATION

The given absolute value equation is

[tex] | - 5x| - 5 = 20[/tex]

We add 5 to both sides of the equation to get:

[tex] | - 5x| - 5 + 5 = 20 + 5[/tex]

[tex] | - 5x| = 25[/tex]

This implies that,

[tex] - 5x = - 25 \: or \: - 5x = 25[/tex]

Divide both sides by -5,

[tex]x = 5 \: or \: x = - 5[/tex]

Answer: - 2/5

Step-by-step explanation: Isolate the vcariable by divding each side by factors that don't contain the variable.

Exact Form: x = - 2/5

Deciaml form: x = -0.4

Hope this helps! :) ~Zane

Hello there! B. -2/5.

To solve for x, you want to get x alone and isolate all other terms.

2 = -6 – 20x  - Start by adding 6 to both sides of the equation.

2+6 = -6+6 – 20x ⇒ 8 = -20x

8 = -20x - Next, divide both sides of the equation by -20..

8/-20 = -20/-20x ⇒ -8/20 = x

Now, we have -8/20 as our value for x. The last step is to simplify. Since 8 and 20 are both divisible by 4, divide both sides of the fraction by 4.

x = -2/5. This is your final answer. I hope this helps and have a great day! ~ saturns

Answer:

The length and the width of the garden is equal to [tex]l=8\ ft[/tex]

Step-by-step explanation:

Let

l -----> the length

w----> the width

we have

[tex]l=\frac{64}{w}[/tex] ------> equation A

If the garden is a square

then

l=w

substitute in the equation A

[tex]l=\frac{64}{l}[/tex]

[tex]l^{2}=64[/tex]

square root both sides

[tex]l=8\ ft[/tex]

therefore

The length and the width of the garden is equal to [tex]l=8\ ft[/tex]

Answer:

y = 1/3 x.

Step-by-step explanation:

The slope of the given line is

(4 - (-2) / 2 - 4)

=   -3.

So the slope of the line perpendicular to it = -1 / (-3) = 1/3.

This line also passes through the point (3, 1) so its equation is ( by the point-slope form):

y - 1 = 1/3(x - 3)

y - 1 = 1/3x - 1

y = 1/3 x (answer).

Answer: The answer is y= x/3

Step-by-step explanation:

Given  points =(2,4)  and (4,-2) whose mid point is (3,1)

Let the points be named  as A(2,4) and B(4,-2) and mid point as C(3,1)

So slope of AB = [tex]\frac{4-(-2)}{2-4}[/tex]

=[tex]\frac{6}{-2}[/tex]

= -3

We know that   Product of Slope of perpendicular lines = -1

Now slope of the line perpendicular to AB × slope of AB = -1

-3 × m2 =-1

i.e. m2 =[tex]\frac{1}{3}[/tex]

Now equation of perpendicular bisector of AB passing through C(3,1)  is

[tex]y -1 =\frac{1}{3}(x-3)\\[/tex]

[tex]y= 1+\frac{1}{3}x -1[/tex]

[tex]y=\frac{1}{3}x[/tex]

Hence the equation of line is y =x/3

Answer:

- 6

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

here [ a, b ] = [ - 7, - 1 ]

f(b) = f(- 1) = (- 1)² + 2(- 1) - 8 = 1 - 2 - 8 = - 9

f(a) = f(- 7) = (- 7)² + 2(- 7) - 8 = 49 - 14 - 8 = 27

Hence

average rate of change = [tex]\frac{-9-27}{-1-(-7)}[/tex] = [tex]\frac{-36}{6}[/tex] = - 6

Answer:

Step-by-step explanation:

Answer:

The slope is 5/3. The equation would be, y = 5/3x + 8/-3.

Step-by-step explanation:

Standard form is "Ax  + By = C

5x - 3y = 8

-5x.         -5x

3y  = -5x + 8

now divide both sides by 3

y = 5/3 + 8/-3

Slope is 5/3

Answer: the last one

EXPLAINATION:

The first one follows the rule a+b=c, and when you add all the angles it equals 180

The second one when you add up all of the angles, it is 180

The third one follows a2+b2=c2. 5(5)+12(12)= 169, 13(13)=169

The last one does not follow any of the triangle rules.

For this case we must factor the following expression:

[tex]-13m-m ^ 2 = 0[/tex]

We have a common factor "m" because it is the common term, so we have:[tex]m (-13-m) = 0[/tex]

Finally, the factorized expression of [tex]-13m-m ^ 2 = 0[/tex] is:[tex]m (-13-m) = 0[/tex]

ANswer:

[tex]m (-13-m) = 0[/tex]

Option B

Answer:

1. The input is f

2. The input is g

3. The input is h

Step-by-step explanation:

The value inside the bracket of the function is the input given to the function.

1. g(f) = 2f

The input is f

2. h(g) = -4+g

The input is g

3. f(h) = h - 7

The input is h

Answer:

g(f)=2f⇒  f

h(g)=-4+g ⇒ g

f (h) =h-7 ⇒h

Step-by-step explanation:

Hi, to answer this question we have to understand what is the input of a function.

A function has an input and an output. The input is inside the parentheses, next to the name of the function.

The input is the independent variable.

Now, with this information, we can match each function with its input.

So:

g(f)=2f⇒  f

h(g)=-4+g ⇒ g

f (h) =h-7  ⇒h

Answer:

The measure of angle 1 is 115°

Step-by-step explanation:

we know that

If ∠1 and ​ ∠2 ​ are a linear pair

then

∠1 +∠2 =180°​ -----> supplementary angles

If ∠2 and ​ ∠3 ​ are vertical angles

then

∠2 =∠3

step 1

Find the value of y

we know that

∠2 =∠3

substitute values

(5+4y)°=(6y-25)°

6y-4y=(5+25)°

2y=(30)°

y=15°

step 2

Find the measure of angle 2

∠2=(5+4y)°

substitute the value of y

∠2=(5+4(15))°

∠2=65°

step 3

Find the measure of angle 1

we know that

∠1 +∠2 =180°

we have

∠2=65°

substitute

∠1 +65°=180°

∠1 =180°-65°=115°

Check the picture below.

now, based on the provided information, we know the hexagon and triangle are regular polygons, equal sides and equal angles, we also know the angle in pink there of E and G are twins inside that irregular trapezoid, and you can see the exterior angles labeled there of 220° and 136°.

now, the trapezoid has twin angles at E and G, that means that the sides of DE and JG are equal and that also means that the other two angles inside that trapezoid are also twins, namely D and J.

if you notice the hexagon on the left-hand-side, a hexagon has interior angles of 120° and if we take a peek at the vertex at D, it has two angles then, one interior or 120° and an exterior of 136°, a full revolution will be 360°, so the remaining angle in green there must be 360° - 120° - 136°  = 104°, and her twin at vertex J is also 104°.

Answer:

See explanation

Step-by-step explanation:

Car A: Started at 0 and ended at 300, thus, car A travels 300 miles.

It travels 6 hours, so car A speed is [tex]\frac{300}{6}=50[/tex] mph.

Car B: Started at 100 and ended at 300, thus, car B travels 300-100=200 miles.

It travels 5 hours, so car B speed is [tex]\frac{200}{5}=40[/tex] mph.

Since 50>40, car A traveled faster than car B.

The graph for the car A is steeper than the graph for the car B.

Since

[tex]6^2 = 36,\quad 7^2 = 49[/tex]

Then we have

[tex]6 = \sqrt{36}<\sqrt{45}<\sqrt{49}=7[/tex]

So, the square root of 45 is somewhere between 6 and 7.

Answer:

C

Step-by-step explanation:

Note that

[tex]\sqrt{36}[/tex] < [tex]\sqrt{45}[/tex] < [tex]\sqrt{49}[/tex], that is

6 < [tex]\sqrt{45}[/tex] < 7

The square root lies between 6 and 7 → point C

Answer:

x = 15

Step-by-step explanation:

∠2 and ∠4 are same side interior angles and are supplementary, thus

2x + 10 + 4x + 80 = 180

6x + 90 = 180 ( subtract 90 from both sides )

6x = 90 ( divide both sides by 6 )

x = 15

Answer:

The smaller number is 11

Step-by-step explanation:

The question is

One number is 3 less than a second number. Twice the second number is 16 less than 4 times the first. Find the smaller of two numbers

Let

x and y the numbers

x=y-3 ----> equation A

2y=4x-16 ----> equation B

Substitute equation A in equation B and solve for y

2y=4(y-3)-16

2y=4y-12-16

4y-2y=12+16

2y=28

y=14

x=14-3=11

Answer: Jacob ran for half an hour, and walked for the remaining half an hour.  15 km/hr x 0.5 hr = 7.5 km running, and 5km/ hr x 0.5 hr=2.5 km walking

Step-by-step explanation:

Let x hours be the time Jacob ran, and therefore for 1-x hours he walked.

time x speed= distance

we get, 15x + 5*(1-x)=10

15x+5-5x=10,

10x=5,

x=0.5 hours.

Average speed was 10km/h.

HOPE THIS HELPS.

Jacob ran 7.5 km at a speed of 15 km/h. By setting up a system of simultaneous equations, we found the distances for both running and walking that add up to the total distance of 10 km, while also fulfilling the constraint of a 1-hour total journey time.

To solve this problem with simultaneous equations, let's define two variables for the two different parts of the journey: x for the distance Jacob runs at 15 km/h and y for the distance he walks at 5 km/h. We know that Jacob covers a total distance of 10 km and the total time taken for the journey is 1 hour.

Set up the equations:

Equation for the distance: x + y = 10

Equation for the time: (x/15) + (y/5) = 1 (Since time is distance divided by speed)

Solve these equations simultaneously.

Multiply the second equation by 15 to clear the denominators: x + 3y = 15

Subtract the first equation from this new equation to solve for y: 2y = 5, so y = 2.5 km.

Substitute y back into the first equation to find x: x = 10 - 2.5, so x = 7.5 km.

Jacob ran 7.5 km at 15 km/h.

Check the answer:

Is 7.5 km in 1 hour at 15 km/h reasonable? Yes, because 15 km/h means he would run 15 km in 1 hour, so running for less than an hour for 7.5 km is plausible.

The statement that best compares the graph of g(x) = -5x³ with the graph of f(x) = x³ is that the graph of g(x) is a reflection of the graph of f(x) across the x-axis and is vertically stretched by a factor of 5."

Option D is the correct answer.

We have,

Reflection across the x-axis:

The negative coefficient of -5 in g(x) reflects the graph across the x-axis compared to f(x).

This means that the points on the graph of g(x) will have the same

x-coordinates as the corresponding points on the graph of f(x) but will have opposite y-coordinates.

Vertical stretching by a factor of 5:

The absolute value of the coefficient (-5) in g(x) indicates that the graph is vertically stretched by a factor of 5 compared to f(x).

This means that for any given x-value, the corresponding y-value on the graph of g(x) will be five times larger (or smaller, depending on the sign) than the corresponding y-value on the graph of f(x).

Thus,

The graph of g(x) is a reflection of the graph of f(x) across the x-axis and is vertically stretched by a factor of 5."
