Answer:
r(x) = -7
Step-by-step explanation:
r(x) = -x - 7
<u>+ 7 + 7</u>
7 = -x
<u>÷ -x ÷ -x</u>
7/-1 = x
-7 = x
To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product.
Answer:
<2 = 34degrees
Step-by-step explanation:
Find the diagram attached below:
First we need to get <1;
<1 + 74 = 180 (angle on a straight line)
<1 = 180 - 74
<1 = 106degrees
Also, <1 + <2 + 40 = 180 (sum of angle in a triangle)
106+<2 + 40 = 180
146 + <2 = 180
<2 = 180-146
<2 = 34degrees
The slope is 6 and the y-intercept is -8
