Answer: b
Step-by-step explanation: It is b because the y-int is -2 so we cancel a and d. For the slope when you start counting from the y-int the one that makes sense is b. HOPE IT HELPS!

(8x + 5)(x - 3) = 0
8x + 5 = 0; x = -5/8
x - 3 = 0; x = 3
Answer
x = -5/8 and x = 3</span>
Answer:
x = 8
Step-by-step explanation:
5( 8 + 7 ) = 5 ⋅ x + 5 ⋅ 7
Add 8 and 7 to get 15.
5 × 15 = 5x + 5 × 7
Multiply 5 and 15 to get 75.
75 = 5x + 5 × 7
Multiply 5 and 7 to get 35.
75 = 5x + 35
Swap sides so that all variable terms are on the left-hand side.
5x + 35 = 75
Subtract 35 from both sides.
5x = 75 − 35
Subtract 35 from 75 to get 40.
5x = 40
Divide both sides by 5.
x = 
Divide 40 by 5 to get 8.
x = 8
Hi, I believe the last scenario best represents an impulse purchase :)
