Answer:

D.) x = 3

Step-by-step explanation:

4 + 3x = 2(3x - 7) + 9

4 + 3x = 6x - 14 + 9

3x - 6x = 9 - 14 - 4

-3x = -9

x = -(-9)/3

x = 9/3

x = 3

Can someone please help me solve this? <br><br> 2x+5y=-1 <br><br> -10x-25y=5
fredd [130]

this is system of equations

2x + 5y = -1   times this one by 5 to make the y's opposite

-10x -25y = 5

10x - 25y = -5  (this is it times by 5, now add them)

__________

0 + 0       = 0    

now since everything cancels and both sides are equal it has infinite solutions beaus they are actually the same line.

A² + b² = c²   a and b are the legs and c is the hypotenuse.

7² + 24² = c²

write a quadratic function that has a graph that contains the following points, (-2, 0), (4, -12), (5,0).
ankoles [38]

Answer:

f(x) =  2x^2 - 6x - 20.

Step-by-step explanation:

(-2, 0) and (5, 0)  are 2 zeroes of the function so we can write the function as

f(x) =  a(x + 2)(x - 5)   where a is a constant.

Now as (4, -12) is a point on the graph:

-12 = a(4 + 2)(4 - 5)

-12 = a * 6 * -1

-6a = -12

a = 2.

So f(x) = 2(x + 2)(x - 5)

f(x) =  2x^2 - 6x - 20.
