The graphs are the shame shape but what is the equation of the red line?

Mathematics

s2008m [1.1K]4 years ago
4 0

Answer:

A

Step-by-step explanation:

Since the shape and vertex x coordinate of both graphs are the same, the only difference is the vertical displacement. Since the blue graph is 4 above the origin and the red graph is 1 above the origin, its graph is:

g(x)=1-x^2

Hence, the correct answer is choice A. Hope this helps!

Find the value of this expression if x= 9. x square + 6 over x-6.
torisob [31]
Hold on, does the equation look like this? (x^2+6)/x-6? Because if so then you'd substitute nine for x first. Then you'd multiply nine by itself getting eighty-one, after that add six to get eighty-seven. substitute nine for x one more and subtract six. take eighty-seven divided by three to get an answer of twenty-nine. But if the equation is saying the square of nine aside from nine squared then you'd have an entirely different problem. That one would look similar to *square symbol*(9)+6/9-6
 , You'd solve this by finding the square of nine which is three then you'd add six and get a numerator of nine. Then you go about the bottom the same as you would have in the first equation, subtract six from nine giving you a denominator of three so you now have nine over three which simplified is three.
 
The two answers are 29 or 3 depending on the equation.

What are the solutions of the equation (x+2)^2-2(x+2)-15=0
Nina [5.8K]

Answer:

The solutions to this are x = -5, and x = 3.

Step-by-step explanation:

This can be solved by rearranging the equation into a proper quadratic format, and factoring it:

(x + 2)^2 - 2 (x + 2) - 15 = 0\\x^2 + 4x + 4 - 2x - 4 - 15 = 0\\x^2 + 2x - 15 = 0\\(x + 5)(x - 3) = 0

This tells us that the x can be equal to  -5 or 3.

Write the equation in slope-intercept form. What are the slope and y-intercept? -12x-4y=10
siniylev [52]

Answer:

  y = -3x -2.5

  slope: -3

  y-intercept: -2.5

Step-by-step explanation:

Solve for y.

  -4y = 12x + 10 . . . . . add 12x to get the y-term by itself

  y = -3x -2.5 . . . . . . .divide by the coefficient of y

__

The slope is the coefficient of x, -3.

The y-intercept is the constant, -2.5.
