Answer:
1. y+5=4x-40
2.y=4x-45
Step-by-step explanation:
To get the slope of a line you do y₂-y₁/x₂-x₁ so we plug in the values -9+5/9-10 and we get -4
Point-slope form states y-y₁=m(x-x₁) where m is the slope so plug in the values we get y+5=4(x-10) and you get y+5=4x-40 then turn this equation into y=mx+b and get y= 4x-45
Answer:
C. Quadrant III
Step-by-step explanation:
Ratio of girls to boys = 5/3
Number of girls in 40 students would be 3/5 * 40 = 24
Answer:
Point C
Step-by-step explanation:
We want to reflect across the x axis
That means the y coordinate changes sign
Z = ( 5 1/2 , 3)
Z' = ( 5 1/2 , -3)
That is point C
Answer:
Step-by-step explanation:
This is how we do it in college, I hope I can be of some help.
First, you multiple 9.6 miles with 5 minutes. Then, you divide your answer with 0.4 miles. Next, you cancel the two mile units because of division and then be left with 120 minutes.
9.6 miles x <u> 5 minutes </u> = <u> 48 miles x minute </u> = 120 minutes
0.4 miles 0.4 miles
