Answer:
m = -3
Step-by-step explanation:
First, find two clear points:
(1, -2) (0, 1)
Then, use the slope formula:
m = <u>y2 - y1</u>
x2 - x1
m = <u>1 - (-2)</u>
0 - 1
= <u>3</u> = -3
-1
m = -3
This means that the rise-over-run is -3 over 1, or 3 over -1.
Which means three down and 1 to the right, or 3 up and 1 to the left.
Slope is the steepness of the line.
Answer:
Step-by-step explanation:
A(1,7); B(-3,-1); slope m =(-1-7)/-3-1) = -8/-4 = 2
Equation of a line AB is
((y-y1) = m(x-x1)
y - 7 = 2(x-1)
y - 7 = 2x-2
y = 2x + 5
Answer:
3rd one, 4th one, 1st one, 2nd one
Step-by-step explanation:
1st one - 2.6
2nd one - (-3.125
)
3rd one - 10.35
4th one - -2.95
Answer:
(6x+3) (4x-5) = 24x^2 -30x +12x -15 = 24x^2 -18x -15
I get the same answer. I guess we're both wrong?
Or do they want it reduced to:
8x^2 -6x -5
Step-by-step explanation:
GIVEN:
total length of the banner = 30 ft.
perimeter of the banner = 96 ft.
total width of the rectangle = ?
Let,
the perimeter be "p"
the length be "L"
the width be "w"
We know,
Perimeter (P) of a rectangle = 2 (L + w)
Substituting the values of P, L and w , we get,
96 = 2 (30 + w)
96 / 2 = 30 + w
48 = 30 + w
48 - 30 = w
18 = w
So, the width of the rectangular banner is 18 ft.
