Answer:
I think It's a triangle too
Step-by-step explanation:
Answer: f-1(x) = 9x + 18.
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = x - 2 ( add 2 to both sides )
y + 2 = x
Multiply through by 9 to clear the fraction
9y + 18 = x
Change y back into terms of x
(x) = 9x + 18
0.3 + 0.02 + 0.006
AND
Three tenths and twenty six thousandths

Answer:
<h2>R
(19, 4)</h2>
Step-by-step explanation:
Given the midpoint 
to be (19.5, 9.5) with one ens point S as (20, 15), to get the coordinate of the other end point, we need to use the formula for calculating the midpoint of two coordinates.
for x coordinate;
X = 
for y coordinate;
Y = 
where (X, Y) is the midpoint
Given 
= 20, and 
= 15, we are to get the coordinate (
, 
)
(X, Y) = ![[\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%2C%20%5Cfrac%7By_1%2By_2%7D%7B2%7D%5D)
(19.5, 9.5) = ![[\frac{20+x_2}{2}, \frac{15+y_2}{2}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B20%2Bx_2%7D%7B2%7D%2C%20%5Cfrac%7B15%2By_2%7D%7B2%7D%5D)
comparing the coordinates;
The coordinate R will be (19, 4)
