Find a polynomial equation that has zeros at x = -4, x = 0, and a double root at x = 7.

Answer:

D

Step-by-step explanation:

Given a polynomial f(x) with roots say x = a and x = b, then the factors are

(x - a) and (x - b) and f(x) is the product of the roots, that is

f(x) = (x - a)(x - b)

Here the roots are x = - 4, x = 0 and double root at x = 7

Thus factors are (x - (- 4)), (x - 0), that is (x + 4) and x

Given a double root at x = 7 the factor is (x - 7)², thus polynomial is

y = x(x + 4)(x - 7)² → D

You are remodeling your kitchen. You've contacted two tiling companies who gladly told you how long it took their workers to til
Ray Of Light [21]
The answer is 7x = 6(x + 15)

x - Jim's rate
y - Pete's rate
<span>Jim completed half the floor in 7 hours:  7x = half of the floor
</span><span>Pete completed the other half of the floor in 6 hours:    6y = half of the floor
So: 7x = 6y

</span><span>Pete can lay 15 more tiles per hour than Jim: y = x + 15

</span>7x = 6y
y = x + 15

Substitute the second equation into the first one:
7x = 6(x + 15)

V-16=-32<br>I need help with the math worksheet how to solve the question
sergeinik [125]

You solve an equation like this by adding the opposite of the constant to both sides of the equation.

... V -16 +16 = -32 +16 . . . . . addition property of equality: if a=c, then a+b = c+b

... V + 0 = -16 . . . . . . . . . . . . additive inverse property of integers: -16+16 = 0

... V = -16 . . . . . . . . . . . . . . . identity element of addition: V+0 = V

_____

<em>You can always do the same thing to both sides of an equation.</em> Here, it is useful to add the opposite of -16 to both sides. That way the constant on the left becomes zero, so you only have the variable by itself—which is what you want.
