I think y = 8. Since x = -3 then the equation would be y = -1(-3) +5. -1 times -3 equals 3. So now the equation is y = 3 +5. That would give you 8.
Answer:
95
Step-by-step explanation:
You multiply base x height and divide by 1/2 to find an area of a triangle.
Let x be the no. of seconds it takes for the balloons to be at the same height.
7+3x = 12+2x
Deduct both sides by 2x.
7+x = 12
Deduct both sides by 7.
x = 5
Ans: It will take 5 seconds for the balloons to be at the same height.
2(x-3)=2x-6 This is distributive property.
2(x-3)= 2x - 2*3 = 2x-6
