Answer:y = 3x + 2
Step-by-step explanation: y = mx + b
Where m is the slope and b is the y-intercept.
Answer:
3
Step-by-step explanation:
8.4 ÷ 3 = 2.8

From 1st equation
d + e = 2
d = 2 - e
From 2nd equation, subtitute d with 2 - e
d - e = 4
2 - e - e = 4
2 - 2e = 4
-2e = 2
e = -1
Find d
d = 2 - e
d = 2 - (-1)
d = 3
The solution is (3,-1)
Okay. The equation for a sphere's surface area is A = 4 * pi * r^2. Let's plug 5 in for r.

I got 314 cm^2 is the surface area, but it always helps to double check work! Hope this helps!
