Domain = { 0,2,-3,-5}
*Domain is the image / the value of x
Answer:
(18,−21)
Step-by-step explanation:
Dilation: multiply each coordinate
(x,y)\rightarrow (3x,3y)
(x,y)→(3x,3y)
Dilations multiply by scale factor
(\color{red}{6},\color{blue}{-7}) \rightarrow (3\cdot \color{red}{6},3\cdot \color{blue}{-7})=\mathbf{(18,-21)}
(6,−7)→(3⋅6,3⋅−7)=(18,−21)
70 m * (100cm)/(1m) * (1 in)/(2.54 cm) = 2755.9 in
.
<span>Rough check, 1 m = 39.36 in approx , 70*39.36 = 2755.2

I think that's how it's done. As far as explaining it goes, I can't do that. I had to ask my math teacher and she wrote the calculations down.
Answer:
A - 5/6
Step-by-step explanation:
-5/7 ÷ 6/7
Copy dot flip
-5/7 * 7/6
Rearrange to make the math easier
-5/6 * 7/7
-5/6
Answer:
$14
Step-by-step explanation:
The revenue from sales of fans is the product of the number of fans sold and the price at which they are sold:
R(p) = n·p = (1960-70p)p
R(p) = 70(28 -p)p
This equation describes a parabola that opens downward and has zeros at p=0 and p=28. The axis of symmetry is halfway between those zeros, at p=14. It goes through the vertex or point of maximum revenue.
The price for maximum revenue is p = 14 dollars.
