Answer:
(x + 10 and (x + 12)
Step-by-step explanation:
x^2 + 22x + 120 = ( ? )( ? )
We need to find two constants whose product is 120 and whose sum is 22.
Let the two constants be a and b. Then:
a*b = 120 and a + b = 22.
It's a bit easier to find a and b such that a + b = 22: 2 and 20, 4 and 18, 6 and 16, and so on. Note that 6 + 16 = 22 (correct) but that 6*16 = 96 (not correct). Try 8 and 14, 10 and 12. Note that 10 + 12 = 22 and that 10*12 = 120. So the desired roots are {10, 12} and the desired factors are (x + 10 and (x + 12).
Check: Does (x + 10)(x + 12) work out to x^2 + 22x + 120?
x^2 + 12x + 10x + 120 = x^2 + 22x + 120? YES
The factors are (x + 10 and (x + 12).
Answer: 2.5
Step-by-step explanation: 0.83333... x 3 = 2.5
You have to be able to know the appropriate properties or postulates to apply on the angles or segments to simplify them. An example would be the Angle Addition Postulate. This postulates states that the sum of the individual measures of the interior angles is equal to the measure of the included angle. There are still a lot more properties to choose from depending on the situation.
Answer:
15) slope=-4 y-intercept is 3 equation is y=-4x+3
16) slope=0 y-intercept is -4 equation is y=0x-4
17) slope=2 y-intercept is 4 equation is y=2x+4
18) slope=1 y-intercept is 4 equation is y=1x+4
Step-by-step explanation:
hope this helps :3
if it did pls mark brainliest
Answer:
These points aren't a function
Step-by-step explanation:
The two points on the y-values are stacked, therefore, the function is not a function.
