Answer:
y = x-1
Step-by-step explanation:
First step is to find the slope
Take two points on the line (1,0) and (2,1)
m = (y2-y1)/(x2-x1)
= (1-0)/(2-1)
= 1/1
The slope is 1
The y intercept ( where it crosses the y axis is -1)
The slope intercept form of the line is
y = mx+b where m is the slope and b is the y intercept
y = 1x-1
y = x-1
A translation of 2 units up will increase the y coordinate by 2 units and a translation by 5 units to the left will decrease the x coordinate by 5. Hence after these translations point (2,2) becomes
<span>(2 - 5 , 2 + 2) = (-3,4) </span>
When point (-3,4) is reflected in the x axis, its y coordinate changes sign and point (-3 ,4) becomes
<span>(-3,-4)</span>
Answer:
A. 10m - 16
Step-by-step explanation:
First, distribute 3 to all terms within the corresponding parenthesis, and -2 likewise:
3(4m - 2) =
3 * 4m = 12m
3 * -2 = -6
3(4m - 2) = 12m - 6
-2(m + 5) =
-2 * m = -2m
-2 * 5 = -10
-2(m + 5) = -2m -10
Combine like terms:
12m - 6 -2m - 10
12m - 2m - 6 - 10
(12m - 2m) + (-6 - 10)
10m - 16
A. 10m - 16 is your answer.

I don't know what your choices are, but I did the questions for you.
R=D/2, R=12, R=radius,
SA= 4 times 3.14 12 times 12, so,
SA=1809.557368, if you round it to two decimal places, it'll be,
1809.56, so the answer is 1809.56in. squared.
