Step-by-step explanation:

I'm good at math ;)

Answer: 0.05 cup

Step-by-step explanation:

Divide 2.5 by 10 to find how much is in one of Sarah’s dishes.

This gives you 0.25

Divide 1.6 by 8 to find how much is in one of Amy's dishes.

This gives you 0.2

Now minus 0.2 from 0.25.

This gives you a 0.05 cup

Answer:

75 square units

Step-by-step explanation:

set up a proportion first.

[tex] \frac{3}{4} = \frac{x}{100} [/tex]

(x is on top because it asks for the smaller area, so it is on the same side of the 3)

after, cross multiply to find x

4x = 300

divide by 4

Answer:

Francesca can buy 4 packages of balloons for $34.

Step-by-step explanation:

35.42 x 100 = 3542 ÷2 = 1771

 8.36 x 100 =   836 ÷2 =  418

1771 ÷ 418 = 4.236842105263158 (We will round it to 4.23)

If we round it to 5, it will exceed Francesca's budget, so we will make 4.23 4.

4 x 8.36 = $33.44

We cannot cut the 44 cents so we will round it to $34.

Answer:

63

Step-by-step explanation:

John's percentage:

36 and 48 have a common factor of 12 so divide both of them by 12.

36/12= 3 and 48/12=4 therefore

so 36/48= 3/4 which is 75% but we don't need to focus on the percent.

Answer:

A

Step-by-step explanation:

let f(x) = y and rearrange making x the subject

y = [tex]\frac{x}{3}[/tex] - 2 ( add 2 to both sides )

y + 2 = [tex]\frac{x}{3}[/tex] ( multiply both sides by 3 to clear the fraction )

3(y + 2) = x

change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then inverse function is

[tex]f^{-1}[/tex] (x) = 3(x + 2)

Answer:

4 inches x 8 inches x 3 inches = 96 inches³

The functions f(x), g(x) and h(x) are related as a result of composite functions

The values of the functions are f(x) = x³ - 5x² + 2x + 8 and g(x) = x² - x - 2

From the question, we have the following equation

h(x) = f(x)/g(x)

This gives

f(x) = g(x) * h(x)

The function h(x) is given as:

h(x) = x - 4

So, we have:

f(x) = g(x) * (x - 4)

The function g(x) cannot be x³ - 3x² - 6x + 8 because the leading coefficients of function f(x) are 3 and 2

Next, we assume that:

g(x) = x² - x - 2

So, we have:

f(x) = (x² - x - 2) * (x - 4)

Expand

f(x) = (x³ - x² - 2x - 4x² + 4x + 8)

Evaluate like terms

f(x) = x³ - 5x² + 2x + 8

The above function exists in the given table.

Hence, the values of the functions are f(x) = x³ - 5x² + 2x + 8 and g(x) = x² - x - 2

Answer:

[tex]y = (x - 7)^{2} + 7[/tex].

Step-by-step explanation:

Let [tex]a[/tex], [tex]h[/tex], and [tex]k[/tex] be constants, and let [tex]a \ne 0[/tex]. The equation [tex]y = a\, (x - h)^{2} + k[/tex] represents a parabola in a plane with vertex at [tex](h,\, k)[/tex].

For example, for [tex]y = -(x + 7)^{2} + 7 = -(x - (-7))^{2} + 7[/tex], [tex]a = (-1)[/tex], [tex]h = (-7)[/tex], and [tex]k = 7[/tex].

A parabola is entirely above the [tex]x[/tex]-axis only if this parabola opens upwards, with the vertex [tex](h,\, k)[/tex] above the [tex]x\![/tex]-axis.

The parabola opens upwards if and only if the leading coefficient is positive: [tex]a > 0[/tex].

For the vertex [tex](h,\, k)[/tex] to be above the [tex]x[/tex]-axis, the [tex]y[/tex]-coordinate of that point, [tex]k[/tex], must be strictly positive. Thus, [tex]k > 0[/tex].

Answer:

D : y = 7x - 20

Step-by-step explanation:

let D be the line that passes through the points (4, 8) and (2, -6)

Then D has an equation of the form D: y = ax + b

Now we need to find a and b in order to be able to write the equation of the line D:

[tex]a = \frac{8-(-6)}{4-2}=\frac{14}{2}=7[/tex]

Since the point (4, 8) lies on the line D then :

8 = 7 × (4) + b

then

8 = 28 + b

then

b = 8 - 28

  = -20

Conclusion:

Since a = 7 and b = -20 then

D : y = 7x - 20

Answer:

x-intercepts are points at which the curve intercepts the x-axis, so when y = 0.

If the vertex of a quadratic function is on the x-axis, there will be only one x-intercept since the parabola will intersect the x-axis at one point only.

If the vertex of the function touches the x-axis, the zero at this point will have a multiplicity of two.  For example, if the vertex is at (4, 0), and therefore the zero is at x = 4, then the function will be [tex]y=a(x - 4)^2[/tex] (where a is some constant).

Answer:

40 Percent decrease

Step-by-step explanation:

We can use a simple formula to solve this problem.

Starting price * X/100 = Ending Price

We plug in our values to solve for X

45 * x/100 = 18

You simplify the equation and you should get X as 40, meaning there is a 40 Percent decrease in price.

Answer:

The slope should be -2

You should go down 2 and go over 1.

Slope Intercept Form: y= -2x+3

Step-by-step explanation:

First, you need to identify the slope: (meaning whether it is a postive or negative.)

In this case, You have a negative slope.

This means instead of rising you're decreasing down.

When you "run" or move horizontally you MUST move right even if it's a negative slope.

Now, you need to identify your Y-Intercept.

Your Y-Intercept should be (0,3)

Next, you have to find your slope:

In order to find your slope, you need to find where the line is crossing the coordinate.

Start at (-1,5) and go down and over to (0,3)

Your answer should be that you went down 2 and over 1.

The slope can't be 2 because if it were to be 2, then that would be a positive slope which isn't our occasion.

The slope is -2.

In Slope Intercept Form: y= -2x+3
