Answer:
slope-intercept form equation: y = x + 5
Step-by-step explanation:
you take the 2 y's, 18 and -13, then you subtract them: 18 - (-13) = 31
then you take the 2 x's, 13 and -18, subtract them too: 13 - (-18) = 31
divide those 2 sums: 31/31 = 1
so the slope is 1
then when you graph it you get an y-intercept of 5
so the equation is y = x + 5
hope this helps :)
Answer:
C
Step-by-step explanation:
One side;
7 x 8 = 56, the side parallel to it is also 56 as well, so 56(2).
Second(bottom) side;
8 x 4 = 32, the side parallel to it(the side above) is also 32 as well, so 32(2).
Third(front) side;
4 x 7 = 28, the side parallel to it(backside) is also 28 as well, so 28(2).
You add all those products to get the surface area:
<em>56(2) + 32(2) + 28(2)</em>
The sum of angles inside a triangle is the sum of angles 1, 2 and 3, which form a straight line, therefore 180 degrees.
The sum of the exterior angles
angle exterior angle
1 2+3
2 1+3
3 1+2
total 2+3+1+3+1+2=2(1+2+3)=2(180)=360 degrees.
Rectangle prisms have 6 flat surfaces.
