Answer: c
Step-by-step explanation:
First find 2 points like say
(0,3) and (1,-2)
now find the slope
3-(-2)/0-1 = -5
the y intercept is already known so the equation is y=-5x+3
Answer:
x=3
y=-1
Step-by-step explanation:
x=4+y
by substitution it in equation 1
weget
(4+y)+y=2
4+2y=2
y=-1
x=3
Answer:
x=4
Step-by-step explanation:
-3x+12-12=x-4-12
-3x=x-16
-3x-x=x-16-x
-4x=-16
-4 divided by -16
x=4
(2(3x4))+(2(4x8))+(2(3x8)) = 24+64+48 = 136
Answer: C
Answer:
- The difference of 15 and 4 times a number
4a - 15
- I want to buy 4 tickets to go to Disney World. They are currently on sale for with a 12% discount.
100% representate the original cost of tikets,
100% = 100/100 = 1
12% discont:
12% = 12/100 = 0.12
1 - 0.12 = 0.88
0.88
then the expressión is:
4*0,88d
=3.52 d
d = original cost of each ticket
