Okay I have the same question as you so first cross out A and C. Because negative numbers are to the left ,and the Answer is D

Answer:

D) [tex]y=\frac{2}{3}x+\frac{3}{2}[/tex]

Step-by-step explanation:

The given equations are in the form;

[tex]y=mx+b[/tex]

We  can observe from the graph that the line is sloping forward.

This means that the slope must be positive.

[tex]\implies m=\frac{2}{3}[/tex]

Also the y-intercept is positive

This implies that;

[tex]b=\frac{3}{2}[/tex]

Hence the equation is [tex]y=\frac{2}{3}x+\frac{3}{2}[/tex]

Answer:

A

Step-by-step explanation:

Let's say Lily invested x amount of money in bonds and 2x in stocks. What the yield is annually from those is 6% of x plus 2 * 8% of x, as she gets 6% in bonds and 8% in stocks. Simplified is 0.06x + 0.16x. Add and you get 0.22x. Now you can solve a simple equation.

Equation:

0.22x = 325.6 (as annual income is $325.60)

----divide both sides by 0.22----

x = 1480

----multiply by 2 to get your answer----

2x = amount of stocks = 1480 * 2 = $2960

Answer:

b. Well, I've gotten y=5x+110 for the line of best fit.

To do so, create a line that fits best for a scatter plot. It's best if it's in the middle and hits most coordinates. So y=5x+110 is a good line.

c. To do so, insert 15 into x and solve from there.

y=5(15)+110

y=75+110

y=185

That is the number of people that might attend the reunion on the 15th year.

Answer:

The desired equation is y = (-8/3)x + 3.

Step-by-step explanation:

There's no one general form; several different forms apply here.

Seeing that the y-intercept is (0, 3) and that another point on the line is (3, -5), I'd use the slope-intercept form here:  y = mx + b

As we move from the first point to the second, x increases by 3 and y decreases by 8.  Thus, the slope of the line through the two points is

m = rise / run = -8/3.  As before, the y-intercept is (0, 3), so b = 3.

The desired equation is y = (-8/3)x + 3.

The answer is:

The first option:

[tex]3x+y-3=0[/tex]

To find which is the equation of the line shown, we need to find  a line that intercepts the y-axis at 3 and the x-axis and 1.

So,  discarding we have:

[tex]3x+y-3=0[/tex]

Making "x" equal to 0 in order to find the y-axis intercept, we have:

[tex]3(0)+y-3=0[/tex]

[tex]y=3[/tex]

Making "y" equal to 0 in order to find the x-axis intercept, we have:

[tex]3x+0-3=0[/tex]

[tex]3x=3[/tex]

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

So, we have found that the x-axis and y-axis intercept of the equation, are the shown in the picture.

The interception points of the equation and the line are:

For x-axis:

[tex](1,0)[/tex]

For y-axis:

[tex](0,3)[/tex]

Hence, the answer is the first option.

[tex]3x+y-3=0[/tex]

ANSWER

y=1

EXPLANATION

If (-1, y) lies on the graph of

[tex]y = 3^{x+1}[/tex]

then it must satisfy its equation:

We substitute x=-1 in to the equation to get:

[tex]y = 3^{-1+1}[/tex]

[tex]y = 3^{0}[/tex]

Any non-zero number exponent 0 is 1.

This simplifies to:

y=1

Therefore when x=-1, y=1

The third choice is correct.

Answer:

The correct answer option is 1

Step-by-step explanation:

We are given the following equation and we are to find the value of y when the point (-1, y) lies on the graph of the given equation:

[tex] y = 3 ^ { x + 1 } [/tex]

So we will substitute the given value of x from the point (-1, y) in the equation to get y:

[tex]y = 3^{-1+1}[/tex]

[tex]y=3^0[/tex]

We know that anything with power zero is equal to 1.

Therefore, y = 1.

Step-by-step explanation:

3/8 + 1/2

Find the LCD and then combine.

7/8 in exact form, and 0.875 as a decimal.

The cost of each adult ticket is $28, but there is no solution for the cost of each student ticket in this case.

To solve this problem, we can set up a system of equations using the given information. Let's represent the cost of an adult ticket as 'a' and the cost of a student ticket as 's'. From the first equation, we know that 4a + 2s = 64. From the second equation, we know that 3a + 3s = 60. Now we can solve this system of equations.

Multiplying both sides of the second equation by 2 gives us 6a + 6s = 120. We can subtract the first equation from this equation to eliminate 's'.

6a + 6s - (4a + 2s) = 120 - 64

Expanding and simplifying the equation gives us 2a = 56. Dividing both sides by 2, we find that a = 28. Now we can substitute this value into either of the original equations to find 's'.

Using the first equation: 4(28) + 2s = 64

Simplifying the equation gives us 112 + 2s = 64

Subtracting 112 from both sides gives us 2s = -48. Dividing both sides by 2, we find that s = -24.

However, since we're talking about the cost of tickets, we can't have a negative value. Therefore, there is no solution for 's' in this case.

The cost of each adult ticket is $28, but there is no solution for the cost of each student ticket in this case.

(-a, -b)

Step-by-step explanation:

It's a square that has both X-axis and Y-axis as lines of symmetry.  We can then conclude the center of the square is at the origin (0,0).

It doesn't matter if the square is straight up (both axis being the mid-points symmetry lines, and one corner in each quadrant) or if it is turned (both axis being the diagonals and the corners are on the axis), in any case if a summit (corner) is defined as (a,b), the opposite corner will be at (-a,-b).

(a,b) could be (2,2), then opposite would be (-2,-2).

(a,b) could be (3,0), then the opposite would be (-3,0).

Answer: 8.4 inches.

Step-by-step explanation:

We know that the circumference of a circle can be calculated with this formula:

[tex]C=2\pi r[/tex]

Where "r" is the radius of the circle.

We know that the circular cake (whose radius is 8 inches) is cut from the center into 6 equal pieces. Then, you need to divide the circumference of this circular cake by 6 to find the width of the outer edge of each piece of cake.

Therefore, this is (to the nearest tenth of an inch):

[tex]C=\frac{2\pi (8in)}{6}\\\\C=8.4in[/tex]

The width of the outer edge of each piece of cake  8.4 inches.

SOLUTION:

Given, a circular cake with a radius of 8 inches is cut from the center into 6 equal pieces. We have to find the width of the outer edge of each piece of cake.

We know that the circumference of a circle can be calculated with this formula: [tex]2\pi r[/tex] where "r" is the radius of the circle.

We know that the circular cake (whose radius is 8 inches) is cut from the center into 6 equal pieces.

Then, you need to divide the circumference of this circular cake by 6 to find the width of the outer edge of each piece of cake.

Therefore, this is (to the nearest tenth of an inch):

[tex]\text { Width }=\frac{2 \pi \times 8}{6}=\frac{\pi \times 8}{3}=\frac{8 \pi}{3}=8.377[/tex]

Hence, the cake piece is 8.4 inches wide.

Answer:

f(x) and g(x) are inverses

Step-by-step explanation:

* Lets check the inverse function

- If f(x) = y has a domain = x and a range = y, then f^-1 is the

  inverse of f with a domain  = y and a range = x

- f(x) = f^-1(x) = x

* Now lets solve the problem

∵ f(x) = 8/x

∵ g(x) = 8/x

∴ fg(x) = f(8/x)

∴ fg(x) = 8/(8/x) = 8 ÷ 8/x ⇒ change division sign to the multiplication

  sign and reciprocal the fraction after the division sign

∴ fg(x) = 8 × x/8 = x

* Now lets find gf(x)

∴ gf(x) = g(8/x)

∴ gf(x) = 8/(8/x) = 8 ÷ 8/x

∴ gf(x) = 8 × x/8 = x

∵ f(x) = f^-1(x) = x

* fg(x) = gf(x) = x

∴ f(x) and g(x) are inverses

Answer:

2, 3, and 4

Step-by-step explanation:

The answer is:

The third option:

2.7 times as much.

To calculate how many more juice will the new can hold, we need to calculate the old can volume to the new can volume.

So, calculating we have:

Old can:

Since the cans have a right cylinder shape, we can calculate their volume using the following formula:

[tex]Volume_{RightCylinder}=Volume_{Can}=\pi r^{2} h[/tex]

Where,

[tex]r=radius=\frac{diameter}{2}\\h=height[/tex]

We are given the old can dimensions:

[tex]radius=\frac{5.2cm}{2}=2.6cm\\\\height=9.4cm[/tex]

So, calculating the volume, we have:

[tex]Volume_{Can}=\pi *2.6cm^{2} *9.4cm=199.7cm^{3}[/tex]

We have that the volume of the old can is:

[tex]Volume_{Can}=199.7cm^{2}[/tex]

New can:

We are given the new can dimensions, the diameter is increased but the height is the same, so:

[tex]radius=\frac{8.5cm}{2}=4.25cm\\\\height=9.4cm[/tex]

Calculating we have:

[tex]Volume_{Can}=\pi *4.25cm^{2} *9.4cm=533.40cm^{3}[/tex]

Now, dividing the volume of the new can by the old can volume to know how many times more juice will the new can hold, we have:

[tex]\frac{533.4cm^{3} }{199.7cm^{3}}=2.67=2.7[/tex]

Hence, we have that the new can hold 2.7 more juice than the old can, so, the answer is the third option:

2.7 times as much.

Distance around Pie = Pi*Diameter

Final answer:

The circumference of a 10-inch diameter cherry pie, using the value 3.1 for Pi, is 31 inches, which is the distance around the pie.

Explanation:

The distance around a circle is known as the circumference. To calculate the circumference of a 10-inch diameter cherry pie, we will use the relationship between the diameter and circumference, which involves Pi (π). The formula for the circumference C is C = π × d, where d is the diameter.

Using 3.1 as the approximate value for π, and with a diameter of 10 inches, we can calculate the circumference as follows:

C = π × d = 3.1 × 10 = 31 inches.

Therefore, the distance around a 10-inch cherry pie from Betsy's Bakery is approximately 31 inches.
