Answer:
Step-by-step explanation:
sports store sells three different packs of tennis balls. Brand A costs $2.50 for two balls, brand B sells three balls for $3.90, and brand C has a sale of four balls for $5.12. Which inequality about the unit price per ball is correct
Brand A:
$2.50 for 2
Brand B :
$3.90 for 3
Brand C:
$5.12 for 4
We calculate the unit price :
Brand A:
$2.50 / 2 = $1.25
Brand B:
$3.90 / 3 = $1.30
Brand C:
$5.12 / 4 = $1.2
1) -16 = v - 14
Add 14 to both sides.
v = -2
2) -2n = -22
Divide both sides by -2.
n = 11
3) 25 = b + 7
Subtract 7 from both sides.
b = 18
Answer:not sure what u talking about
Step-by-step explanation:
Answer: Okay so you will first come over and take out the a and b and then that will become c and then you add the rest of the numbr up equaling to
7
Step-by-step explanation: why because 7 is the answer and i know it for all of them your teacher tricked you so you would get a diffrent answer just put 7 trust

F(x)=-1x-1
1) Pick 2 points on the line (i chose (-4,3) and (3,-4)
2) Find slope of the line using the 2 points. (work below)
3) Find y-intercept, which is the point where y-axis and the line cross (y-intercept is -1).
4) Place both slope and y-intercept into slope-intercept form, y=mx+b (m=slope and b=y-intercept.)
5) Change y to f(x) (meaning function of x).
Work:
3-(-4)/-4-3=3+4/-4-3=7/-7=-1
y-intercept equals -1 also.
y=mx+b
y=-1x+(-1)
y=-1x-1
f(x)=-1x-1<---Answer
