What is the range of the given function?

Fed [463]

9514 1404 393

Answer:

(b) {yly = -9, -3, 0, 5, 7}

Step-by-step explanation:

The range is the set of y-values in the ordered pairs. It is usually convenient to list a set in alphanumeric order.

The second values of the ordered pairs are 0, -3, -9, 5, 7. So, the range is ...

y ∈ {-9, -3, 0, 5, 7} . . . . . matches the second choice

What is the equation of a line, in point-slope form, that passes through (-8, 1)and has a slope of ?

Serggg [28]

Answer:

y-1 = 5(x+8)

Step-by-step explanation:

The standard equation of a line in point slope form is expressed as;

y-y0 = m(x-x0)

m is the slope

(x0, y0) is the point

Given

Slope m = 5 (assumed value)

Point (-8,1)

Substitute the given data's into the formula

y -1 = 5(x-(-8))

y-1 = 5(x+8)

Hence the required equation is y-1 = 5(x+8)

Answer:

The scale factor is $\frac{3}{2}$

Step-by-step explanation:

The volume of the original prism is $V_P=980cm^3$

The volume of the dilated prism is $V_Q=3307.5cm^3$

Let the scale factor be $k$ .

To find the volume of the dilated prism, we multiplied by $k^3$ .

$\Rightarrow 980k^3=3307.5$

$\Rightarrow k^3=\frac{3307.5}{980}$

$\Rightarrow k^3=\frac{27}{8}$

$\Rightarrow k=\sqrt[3]{\frac{27}{8}}$

$\Rightarrow k=\frac{3}{2}$

You have two dollars and 50 Cent the gumballs in the machine cost $.25 each right and solve an inequality represents the number

vladimir2022 [97]

Answer:

The maximum number of gumballs you can buy is 10

Step-by-step explanation:

Let

x ---->represents the number of gumballs you can buy

we know that

The number of gumballs you can buy multiplied by it cost must be less than or equal to $2.50 (two dollars and 50 cents)

The inequality that represent this situation is

$0.25x\leq 2.50$

solve for x

Divide both sides by 0.25

$x\leq 10$

therefore

The maximum number of gumballs you can buy is 10
