Write a quadratic function f whose zeros are -9 & -1

Mathematics
1 answer:
olganol [36]3 years ago
7 0

Step-by-step explanation:

This is most easily solved by writing the factored form:

f(x) = (x + 9)(x + 1)

Notice how, if we were to substitute -9 for x, the left part would be -9 + 9 = 0. Since (x + 1) × 0 = 0, this makes the function 0. The same logic applies for the right part.

X + 6 = −x − 6<br> (so i can ask)kjhgfdccfghjk
ratelena [41]

Answer:

<em>x = -6</em>

Step-by-step explanation:

<u>Equations</u>

Solve the equation:

x + 6 = -x - 6

We must find the value of x that makes the identity above true.

Let's join all the variables on the left side and the numbers on the right side.

Adding x:

x + 6 + x = -x - 6 + x

The variables cancel out on the right side:

2x + 6 = -6

Subtracting 6:

2x + 6 - 6 = -6 -6

The 6 and -6 are canceled out:

2x = -12

Dividing by 2:

x = -12/2

x = -6

Which operation will solve the following word problem? Jeff earns $14.00 per hour, Tom earns half as much as Jeff. How much does
disa [49]

Answer:

The correct option is (d).

Step-by-step explanation:

Given that,

Jeff earns $14.00 per hour.

Tom earns half as much as Jeff.

We need to find the amount earn by Tom per hour.

Tom's amount = Jeff's amount/2

So,

T=\dfrac{14}{2}\\\\T=\$7

So, Tom earn $7 per hour. Hence, division operation is used. Jeff's amount is divided by 2.

How many solutins<br> 6x + 35 +9x =15x(x+4) -25
Sveta_85 [38]
Hi again............. I am glad to help you again.

6x + 35 + 9x = 15x(x+4) -25
6x + 35 + 9x = 15x² + 60x - 25
15x + 35 = 15x² + 60x - 25
Now, we gonna put all the common terms together
15x - 60x + 35 + 25 - 15x² =
-45x + 60 - 15x² = 0
Now, we need to factorize
-15(x-1)(x+4)=0
Set factors equal to 0
x -1 = 0 or x + 4 = 0
x = 1 or x = 4


I hope that's help !

Please help me it would mean a lot

42.5 i think

The whole angle is 127 minus the angle we know (32) this leaves us with 85 for the rest of the angle but we still have to deal with the angle bisector so we divide it by 2 leaving us with 42.5 I'm pretty sure.
