−10x + 1 + 7x = 37
-10x+7x+1=37
-3x+1= 37
Move +1 to the other side. Sign changes from +1 to -1.
-3x+1-1= 37-1
-3x=36
Divide by -3.
-3x/3= 36/-3
x= -12
Answer : x= -12
1) x² - 13x + 30 = 0
x² ⇒ x * x
-13x ⇒ -10x - 3x
30 ⇒ -10 * -3
(x-10) (x-3) = 0
x - 10 = 0 ⇒ x = 10
x - 3 = 0 ⇒ x = 3
Answer is Choice D:) x = 3 or x = 10
2. P(x) = 480x - 2x²
a) P(100) = 480(100) - 2(100²) = 48,000 - 20,000 = 28,000
b) P(120) = 480(120) - 2(120²) = 57,600 - 28,800 = 28,800
c) P(240) = 480(240) - 2(240²) = 115,200 - 115,200 = 0 THIS IS THE ANSWER.
Answer:
Infinite many solutions. Any x-value can satisfy the equation.
Step-by-step explanation:
Let's work on simplifying the equation a little to investigate which x-values satisfy it. Start by combining like terms on the left side (6x +4x=10x),
then distribute the factor "10" into the binomial (x+10), obtaining 10x +30.
Now we have the same expression on the left and the right of the equal sign:
10x +30=10x+30. We may subtract 30 from both sides, and obtain 10x=10x, and at this point divide by 10 both sides, and we obtain: x=x
The process is shown below.
x=x is an equation that is verified by absolutely ANY x value on the number line, and there are infinite x-values in the number line.
Therefore there are infinite many solutions to this equation (any x-value will satisfy it).

Answer:
For the equation, you should subtract 2x on both sides to get -y = -2x - 4. Flip the y's negative sign to get a proper function which is y = 2x + 4. The y-intercept is at (0, 4) and each unit will move two units up along the x-axis.
