Answer:
15
Step-by-step explanation:
To find how many she bought, we have to divide. So we do 105/7=15.
5x^2+24x-5 factored is: (5x - 1)(x + 5)
What you want to do is change the variable positions of X and Y
So it would be a new equation of
x = 1/2y + 3
Then you would need Y to be by itself so you solve for that
x-3 = 1/2 y
then,
2(x-3) = y
Your inverse function is 2(x-3) = y
Hope this helped :D
Correct option - B
Let's check all of them
A. 93 x 1 = 93 its not equal to -93
B. 31 x -3 = -93 ,this one matches
C. -31 x -3 = 93, again not equal
D. -93 x -1 = 93, not equal
So the answer is B

Answer:
y = - 3x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (2, - 2) ← 2 points on the line
m =
=
= - 3
Note the line crosses the y- axis at (0, 4) ⇒ c = 4
y = - 3x + 4 ← equation of line
