Step 1: move all terms to one side
7 + 2x^2 - 10x = 0
Step 2: Use the quadratic formula
X = 10 + 2(square root of 11). 10-2 _/—-11

Answer: x=13
Step-by-step explanation: ?+?=35
(2x-4)+x=35
3x-4=35
3x=35+4
3x=39
x=13
*Hint: When you have two y's, they could equal each other in order to solve for the x value.
|x^2 -3x + 1| = - (x - 1)
x^2 -3x + 1 = -x + 1
x^2 - 2x + 1 = 1
x^2 - 2x = 0
x (x - 2)
x = 2 and x = 0
Once both of them are plugged in, only x = 2 works so that's the value for x. Now we just plug it in order to solve for y.
y = x - 1
y = 2 - 1
y = 1
(2, 1)
The answer would be C.
Answer:
-2
Step-by-step explanation:
Note that slope-intercept form looks like: y = mx + b
In this case, isolate the y. Note the equal sign, what you do to one side, you do to the other. Subtract 2x from both sides:
2x (-2x) + y = 6 (-2x)
y = -2x + 6
Note in the slope-intercept form: y = mx + b
y = y
m = slope
x = x
b = y-intercept
In this case, your slope is -2. All lines parallel to the given equation will also have a slope of-2.
