Answer:
12) y = 2x + 8
13) ( -4, 3)
14) y + 3 = 1(x + 2) ; y = x - 1
Step-by-step explanation:
12) ( -2, 4) and (1, 10)
m=(y2-y1)/(x2-x1)
m= (10-4)/(1+2)
m=6/3
m = 2
y - y1 = m(x - x1)
y - 4 = 2(x + 2)
y - 4 = 2x + 4
y = 2x + 8
13)
y - y1 = m(x - x1)
y - 3 = 2(x +4)
( -4, 3)
14) ( -2, -3) and (4, 3)
m=(y2-y1)/(x2-x1)
m=(3+3)/(4+2)
m=6/6
m=1
y - y1 = m(x - x1)
y + 3 = 1(x + 2)
y + 3 = x + 2
y = x - 1
Answer:
The correct answer is: She bought 2 dress shirts and 5 t-shirts
Step-by-step explanation:
Let's marked dress shirts with x and t-shirts with y.
Now we will make equations to solve this problem:
x + y = 7 => y = 7 - x
40 x + 8 y = 120
When we replace y = (7 - x) in the previous equation we get:
40 x + 8 (7 -x) = 120 40 x + 56 - 8 x = 120 => 32 x = 120 - 56 =>
32 x = 64 => x = 64/32 = 2 => x = 2
y = 7 - x = 7 - 2 = 5 => y = 5
x = 2 dress shirts
y = 5 t-shirts
