Think of the letter 'a' to represent 1 apple.
a = 1a = 1 apple
2a = 2 apples
3a = 3 apples
and so on
Adding 7a with 4a means we have 7 apples and we add on 4 more. We'll have 7+4 = 11 apples total.
Algebraically we write 7a+4a = 11a to do this using shorthand.
The 9-7 portion is calculated like you'd expect and it simplifies to 2.
------------
Here's what the step by step picture looks like
(7a+9) + (4a-7)
7a + 9 + 4a - 7
(7a+4a) + (9-7)
11a + 2

5x + 3 = 38
5x = 38-3
5x = 35
x= 7
Answer:
John and Mike are correct.
Step-by-step explanation:
Slope = (8 - 0)/(0 - 4) = -2
y intercept b = 8
y = mx + b where m = - 2 and b = 8
So equation y = -2x + 8
Answer
D. last one
y = -2x + 8
