Answer:
-2.9
Step-by-step explanation:
-10x + 1 + 7 = 37
Combine like factors.
-10x + 8 = 37
Subtract 8 from both sides.
-10x = 29
Divide both sides by -10.
x = -2.9
Answer:
MEDIUM JERSEY =$21
Step-by-step explanation:
MEDIUM=$X ,LARGE =$X+9, EX LARGE=$X+15
9(X+9)+4(X+15)=414
9X+81+4X+60=414
13X=414-141
13X=273
X=21

Answer:
C. (0,-3)
Step-by-step explanation:
y = 2x - 3
We only need to focus on "- 3" because it represents "b" of the equation y = mx + b.
Since it is a y intercept, the coordinate must be at the y axis.
So,
x = 0
y = -3
(0,-3)
(x-3)(x-5)=35
Multiply the brackets together
x*x-5*x-3*x-3*5
x^2-8x+15=35
Move +35 to the other side. Sign changes from +35 to -35
x^2-8x+15-35=35-35
x^2-8x-20=0
(x-10)(x+2)=0
x-10=0 x+2=0
Move -10 to the other side. Sign changes from -10 to +10
x-10+10=0+10 x+2-2=0-2
x=10 x=-2
Answer: x=10
