Answer:
y=-2x-5
Step-by-step explanation:
First of all, you have to distribute -2 to (x-1) to get to this equation y+7=-2x+2. Then, you subtract 7 on both sides to get the slope-intercept of y = -2x - 5.
Answer:
No
Step-by-step explanation:
Do they have common factors?
No which is why they are not able to be simplified further
so no
-0.4x=2.5 divide both sides by -0.4
x=-6.25
Answer: Andy is 35 and Mike is 21.
Step-by-step explanation:
Andy’s present age: Mike’s present age
= 5:3
Andy’s age in “if”: Mike’s age in “if”
=6:2
1 unit = 7
5 unit = 35 (Andy’s age)
3 unit = 21 (Mike’s age)
