Hey yall this is an absolute value thingy its been stressing me out so please help
weeeeeb [17]

Answer:

1. 4 or -4

2. 2 or -2

3. 5 or -1

4. 2

5. -2

6. 1 or 2

Step-by-step explanation:

Absolute values make the answer a positive value. So in the first one to make |x|=4, x can be either 4 or -4 because the lines around x tell you to remove the negative sign. Does this make sense? So for the answers, find the values for x that make the answer the value wanted, and then find the negative of the value wanted. For example, in |5x|=10, 5(2)=10 and 5(-2)=-10. But with absolute value signs, it changes it from -10 to 10.  Hope this helps, if you have any questions please let me know.

What are the x-intercepts of the graph of y= x^2 + 7x + 12?
jok3333 [9.3K]

Answer:

B. (-4,0) and (-3,0)

Step-by-step explanation:

I used a graphing tool to graph the equation. The parabola intercepts at (-4,0) and (-3,0). Therefore, (-4,0) and (-3,0) are the x-intercepts of the equation.

Option B should be the correct answer.

PLEASE HELP! I will award brainliest to the most helpful answer. I need an in depth explanation, not just the answer. How do you
Svetradugi [14.3K]

Answer:

y ≤ -4x+25

Step-by-step explanation:

First we need to figure out the equation for the line

The y intercept is  25

Next figure out the slope

slope = (y2-y1)/((x2-x1)

      = (49-25)/(-6-0)

      = 24/-6

    = -4

The equation for a line in slope intercept form is y = mx+b

y = -4x+25

This is a solid line so our inequality will have an equals in it.

It is shaded below, so y is less than.

If it was shaded above, y would be greater than

y ≤ -4x+25

Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation.
Alisiya [41]

Answer: b.

Step-by-step explanation:

Based on the information given, you can write the following expression:

y=\frac{k}{x^2}

Where k is the the constant of variation

If y=4/63 when x=3, then you can substitute these values into the expression and solve for k:

\frac{4}{63}=\frac{k}{3^2}\\k=9*\frac{4}{63}\\k=\frac{4}{7}

Substitute k into the expression. Then the equation is:

y=\frac{4}{7x^{2}}

Substitute x=5  into the equation. Then, y is:

y=\frac{4}{7(5)^{2}}=\frac{4}{175}}
