Answer: B
Step-by-step explanation:
so for the slope to be parallel, it means it's the same slope as the given equation which is -5
using point slope, we can write a new equation
y -5 = -5(x+3)
y -5 = -5x-15
y = -5x-10
Answer:
Step-by-step explanation:
the answere is 1/5
juat have to have trust
Steps:
1. Take -x + 2y= 21
2. Add x on both sides
2y= x + 21
3. Divide everything by 2
Y= 1/2x + 10.5
4. Substitute the y in 7x + 2y= -19 for 1/2x + 10.5
7x + 2(1/2x + 10.5)= -19
5. Multiply everything in parentheses
7x + x + 21= -19
8x + 21= -19
6. Subtract 21 on both sides
7. 8x=-40
8. Divide each side be 8
9. Your answer is
X=-5
It’s c got perfect from this
X=1,
X=-3
