What is the value of x? −7.5(x−3)=3.75

Elena L [17]

${\boxed{ \Huge{ \blue{ \mathcal{{ Answer}}}}}}$

⇛-7.5(x−3) = 3.75

⇛-7.5x + 22.5 = 3.75

⇛-7.5x = 3.75 - 22.5

⇛-7.5x = -18.75

⇛x = -18.75 ÷ -7.5

⇛x = -18.75/-7.5

⇛x = 2.5

Solve the equation 40 = -10(y+0.3). what does the y equal

alexdok [17]

Answer:

y = -4.3

Step-by-step explanation:

40 = -10(y + 0.3) {Step 1: Use the distributive property to multiply -10 by y + 0.3}

40 = -10y + -10(0.3)

40 = -10y - 3 {Step 2: Add 3 to both sides.}

40 + 3 = -10y

43 = -10y {Step 3: Divide both sides by -10}

43/-10 = y

-4.3 = y

y equals -4.3.

An equation for annealing soda-lime glass is y(t)=−14t+500 , where t is time in minutes and y is the temperature of the glass in

beks73 [17]

An equation for annealing soda-lime glass is y(t)=−14t+500 , where t is time in minutes and y is the temperature of the glass in ˚C.

To find the y intercept , we plug in 0 for t

y intercept is the value , where time is 0 minutes

so we plug in 0 for t and find out y(0)

y(t)=−14t+500

y(0)=−14(0)+500 = 500

When t=0 , the value of y = 500

So , y intercept is (0,500)

Which describes how to graph g (x) = RootIndex 3 StartRoot x minus 5 EndRoot + 7 by transforming the parent function?

ratelena [41]

Answer:

$f(x) =\sqrt[3]{x}$

Step-by-step explanation:

Hello!

Considering the parent function, as the most simple function that preserves the definition. Let's take the function given:

$g(x) = \sqrt[3]{x-5}+7$

To have the the parent function, we must find the parent one, let's call it by f(x).

$f(x) =\sqrt[3]{x}$

This function satisfies the Domain of the given one, because the Domain is still $(-\infty, \infty)$ and the range as well.

Check below a graphical approach of those. The upper one is g(x) and the lower f(x), its parent one.
