Gave away 7 ⇒ -7
Bought 6 ⇒ + 6
Left with 13
If he did not buy the 6 cars ...
13 - 6 = 7
If he did not give the 7 cars away ...
7 + 7 = 14
He has 14 cars at first.
13 - 6
Answer:
-4x^12y^11z^4
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
First find h (60)
Let x= 60
h(60)=1/5 *60-7
=12-7
= 5
We want to find 3 •h(60)
3 * 5
15
This is an example of associative property of multiplication.
Associative property of multiplication is when you could multiply numbers regardless of how they are grouped.
To be perpendicular the product of the two slopes must equal -1.
2m/5=-1
2m=-5
m=-2.5
since y=mx+b we have so far
y=-2.5x+b, using point (-3,4) we can solve for b
4=-2.5(-3)+b
4=7.5+b
b=-3.5 so
y=-2.5x-3.5 We can multiply the whole equation by two so that the coefficients are integers...
2y=-5x-7 add 5x to both sides
5x-2y=-7
