Answer:

B.   (x - 6)(x + 2).

Step-by-step explanation:

x^2 - 4x - 12

We need 2 numbers whose product is the last number -12 and whose sum is the coefficient of x (-4).

These numbers are -6 and + 2.

So the factors are (x - 6)(x + 2).

How to know the derivative of a function by looking at the graphs?
ozzi
The derivative is the gradient.

At any local Max's or min's the derivative graph will cut the x axis.

For example a graph x^2
The derivative will have a positive gradient as the gradient is increasing at the lower values then at x=0 the gradient is 0 so the derivative graph will pass the point (0,0). Remember that the derivative graph will be linear.

To get more detail find the points the graph crosses the x axis and put into for a(x-q)(x-p)=0 you will have to solve for 'a' by finding a point on the graph and substituting it in. Then you can find the derivative of that function and graph it

Which expression is equivalent to -7(y - 2)
Neko [114]

The expression equivalent to -7(y - 2) is -7y + 14

<h3>Which expression is equivalent to -7(y - 2)?</h3>

Given the expression; -7(y - 2)

We expand the expression by multiplying each element inside the parentheses the element out i.e -7

-7(y - 2)

[ -7 × y and -7 × -2 ]

-7y + 14

Therefore, the expression equivalent to -7(y - 2) is -7y + 14.

pantera1 [17]

Answer:

22 Red Jellybeans

Step-by-step explanation:

Out of the 55 jellybeans in the jar, 40% of them are red, which means you have to do 40% of 55 to see which ones are red. We know 10% of 55 is 5.5, then multiply 5.5 x 4 to get 22 is 40% of 50 hope this helped :)

What is the equation of the line passing through the points (-25, 50) and (25, 50) in slope-intercept form?
babunello [35]

Answer:

Y = 50x

Step-by-step explanation:

Remember that slope intercept form is Y = mx + b indicating that m is the slope

To solve this equation use the formula

Y2 - y1 , x2 - x1:

50 - (- 50) = 100

25 - (-25) = 50

100/50 = 50/1

So the answer is y = 50x
