use the equation (y-y)=m(x-x). for example with the first equation: (y-7)=-4(x-2) distribute the slope into the (x-2). this will give you (y-7)=-4x+8. then you add the 7 to both sides to cancel it. this gives you y=-4x+15. hope this helps!! :)
Answer:
$150
Step-by-step explanation:
There are three pans of brownies each containing 25 brownies and 25 × 3= 75. Each brownie sells for $2. So, 2×75=150.
The formula used for calculating the time is:
t = d / v
where t is time, d is distance and v is velocity
We know that the difference in the two times is 3 hours, therefore:
d / 65 – d / 130 = 3
Calculating for d:
d = 30 / (1/65 – 1/130)
<span>d = 3900 miles</span>
Step-by-step explanation:
7p – 3q
if p= 8 and q = -5
7(8)-3(-5)
56+15
=71
Answer:
According to my very precise calculations, I've come to the conclusion that the answer is 1.
