The point B has coordinates (-4,2) and C has coordinates (-2,-2). We are going to calculate the slope of the line
Then, we are going to calculate the intercept using the slope m=-2 and the point (-4,2).
y=mx+b
2 = -2*(-4)+b
Isolating b we get
2-8=b= -6
The equation would be
y=-2x-6, option A
B. -10x>= -100 is for the first graph.
A. n/4<= -1 is for the second song
Hope this helps
Answer:
x=0 x = 3/4
Step-by-step explanation:
32x^2 – 24x = 0
Factor out 8x
8x(4x -3)
Using the zero product property
8x = 0 4x-3 =0
x=0 4x=3
x=0 x = 3/4
First find the slope between any two points:
Where
are the two points
So calculating the slope:
So the slope is
And our equation will be in the format of
where
and
So, now we have half of the equation:
Now to calculate b, we can plug in a point
and solve for b.
So
Lets use the point
So:
And then:
So our final equation is
Answer:
25% discount
Step-by-step explanation:
48*2=96
However, instead one pair is 50% off. So, one pair will be $48 and another will be $24. So, if you purchase two pairs, you only have to pay$72. 72/96=.75. This means you are paying for 75% of the original price, meaning you got 25% off discount.
