12. (24.4D) For what value of c will the graphs of

weqwewe [10]

Answer:

$c=144$

Step-by-step explanation:

we have

$y=2x^2-36x+c$ ---> equation A

$y=2(x-9)^2-18$ ---> equation B

Convert the equation A into vertex form and then compare with equation B

we have

$y=2x^2-36x+c$

Factor 2 leading coefficient

$y=2(x^2-18x)+c$

Complete the square

$y=2(x^2-18x+81)+c-162$

Rewrite as perfect squares

$y=2(x-9)^2+(c-162)$

Compare with equation B

$c-162=-18$

solve for c

$c=-18+162$

$c=144$

What do you know to be true about the values of a and b?

myrzilka [38]

Answer:

Step-by-step explanation:

Total angle of each triangle=180°

From the question, the shapes of both triangles are just the same

x=40°

y=60°

a+60°+x=180°

a+60°+40°=180°

a=80°

b+40°+y=180°

b+40°+60°=180°

b=80°

a=b

Which equation is not a function? 2+x-x2=14 x2-x-10=24 y2+3x=6 2y+3x=6

Andrews [41]

Answer:

The correct options are 1,2 and 3.

Step by step explanation:

According to the definition of function there exist unique value of y for each value of x in the domain of the function.

If equation have more than one values of y for any value of x, then the equation is not a function.

$2+x-x^2=14$ .... (1)

$x^2-x-10=24$ ... (2)

A quadratic equation have two values of x and the value of y can be any number. So a quadratic equation is not a function.

The first and second equations are quadratic equations so the equation (1) and (2) are not functions.

The third equation is

$y^2+3x=6$

The degree of y is 2. It means for each value of x there exist two values of y.

Put x=0, then we get

$y=\pm \sqrt{6}$

More than one values of y exist for single value of x.

So the equation (3) is not a function.

The fourth equation is

$2y+3x=6$

Since the degree of x is 1 and degree of y is also 1, therefore it is a linear equation and for each value of x there exist a unique value of y.

Therefore the equation (4) is a function.
