Answer:
a. or 
Step-by-step explanation:
Slope is equal to y1-y2 over x1-x2.
So the equation would be:
2-(-1)=2+1=3
-3-(-1)=-3+1=-2
So the answer is:
Answer:
4665 approx
Step-by-step explanation:
Given data
Total number of crashes= 16,370 automobile crashes
Percentage caused by distraction =28.5%
Let us find the number of crashes caused by distraction
=28.5/100* 16,370
=0.285* 16,370
=4665.45
Hence the number of crashes caused by distraction is 4665 approx
Answer:
= 9y^4 -6y^3 -17y^2 -18y -10
Step-by-step explanation:
(3y^2 + 2y + 2) x (3y^2 – 4y – 5)
9y^4 - 12y^3 - 15y^2 + 6y^3 -8y^2 -10y +6y^2 -8y -10
= 9y^4 -6y^3 -17y^2 -18y -10
Answer:
the last one
Step-by-step explanation:
when something asks for product it means multiplication
to get 2 times -5, you move first to -5 then to -10
Answer:
1 inch
Step-by-step explanation:
Factors of 63 are 7 and 9, each of which is 2 more than the dimensions of the photo. Sarah's frame is 1 inch wide.
_____
A 1-inch wide frame adds 2 inches to length and width.
_____
<em>Solution using an equation</em>
If you let w represent the width of the frame, the area of the framed photo is ...
(5+2w)(7+2w) = 63
4w^2 +24w -28 = 0 . . . . write in standard form
w^2 +6w -7 = 0 . . . . . . . . divide by 4
(w -1)(w +7) = 0 . . . . . . . . factor
The positive solution to this equation is w=1.
The width of the frame is 1 inch.
