Answer:

Step-by-step explanation:

● h(x) = 2-2x

The domain is {-3,-2,1,5}

● h(-3) = 2-2×(-3) = 2+6 = 8

● h(-2) = 2 -2×(-2) = 2+4 = 6

● h(1) = 2-2×1 = 2-2 = 0

● h(5) = 2-2×5 = 2-10 = -8

The range is {-8,0,6,8}

the distance around a circle (the circumference) is about 3.14 times the diameter. If a circulares table has a diameter of 3 fee

Katyanochek1 [597]

Well.
The relation between the circumference of a circle and its diameter is described by the following equation: $Thecircumference=\pi d$
where d is the diameter of the circle.
For a giving diameter (d=3ft), we can substitute in the previous equation
The circumference of a circule= 3.14*3 (you can use ur calculator to find the exact number i guess it will be about 9.42 ft)

I hope it helps.

21 is 84% of what number?

Radda [10]

21 is 84% of 25

Convert the percentage (84) into a decimal by dividing it over 100:
$\frac{84}{100} = 0.84$

Divide 21 over 0.84:
$\frac{21}{0.84} = 25$

Solve 4y-1=7 plz step by step

miv72 [106K]

Hi,

Here we are going to be working on isolating the variable y, and seeing what its value equates to.

To do this, we must try and get the variable y on one side of the equation by itself.

Let's look at step one -

4y - 1 = 7

We want to get rid of the 1 since we need to isolate x. We do this by doing the inverse of its operation. Since 1 is negative, if we add positive 1 to it - we will get 0, thereby being closer to isolating y.

However, when we do something on one side of the equation we must do it on the other. This means we will add 1 on both sides.

4y - 1 + 1 = 7 + 1

4y = 8

Remember how I mentioned we do the inverse of the operation? In this case, 4 is multiplying y. The inverse operation of multiplication is division. So, to get rid of the 4 - we must divide 4y by 4, on both sides.

4y / 4 = 8 / 4

y = 2

We now know the variable y is equal to 2.

Hopefully, this helps.
