These are in y=mx+b form where m=slope
sometimes b=0
vertical intercept means the y-intercept and the horizonatl intercept is the x intercept so the x intercept is when y=0 and the y intercept is when x=0 so the first one is
y=5x-15
slope=5
y-intercept=-15
x-intercept=3
y=7-x
this can be written as
y=-1x+7
slope=-1
y-intercept=7
x-intercept=7
4x=2y=12
we must get it into slope intercept form
divide the whole thing by 2x=y=12
we can disregard the 12 and get
2x=y or y=2x+0
slope=2
y-intercept=0
x-intercept=0
Answer:
D
Step-by-step explanation:
SOH
sinФ = opposite/hypentenous
sin35 = x/20
0.574 = x/20
cross multiply
x = 20(0.574)
x = 11.48
Round to the nearest tenth.
x = 11.5

Answer:
infinite solutions
Step-by-step explanation:
y=5-2x
4x+2y=10
Multiply the first equation by 2
2y = 10 -4x
Add 4x to each side
4x+2y = 10
This is identical to the second equation
This means they are the same line, so there are infinite solutions along the line
Answer:
Mr. Prieto can buy 6 pizzas
Step-by-step explanation:
Cost of 5 soda's = 5 * 2 = $ 10
Remaining amount with him after buying 5 soda's= 94 - 10 = $ 84
Number of pizza's = Remaining amount/cost of 1 pizza
= 6 pizzas
