This is the answer right?
dalvyx [7]
No, the question is stating the product of a number (the variable n represents the number) and 10 is 142. In other words, 10 times another number is 142. Hence, the answer would be A.

What are the zeroes of f(x) = x2 + 5x + 6?
Vera_Pavlovna [14]

Answer:

Zeros are x = −2, −3 .

Step-by-step explanation:

Given : f(x) = x² + 5x + 6.

To find : What are the zeroes of f(x).

Solution : We have given that

f(x) = x² + 5x + 6.

To find the zeros of the function we need to set f(x) = 0.

x² + 5x + 6 = 0.

On factoring

x² + 3x +2x + 6 = 0.

Taking common x from first two term and 2 from last two terms

x ( x + 3) +2 ( x +3) = 0.

On grouping

(x + 3) (x + 2)  = 0

Now, x + 3 = 0   and x + 2 = 0

x = -3 and x = -2

Therefore, Zeros are x = −2, −3 .

Mr. pham wrote the equation below on the board.
valkas [14]

18 - 7x = -20.5

Subtract 18 from each side:

-7x = -38.5

Divide both sides by -7:

x = -38.5 / -7

x = -5.5 = 5 1/2

The answer is D.

<u>IF YOU NEED SLOPE-INTERCEPT FORM</u>

2x + 3y - 7 = 0

3y = -2x + 7

y = -\frac{2}{3} + \frac{7}{3}

<u>IF IT IS KIND OF HOW YOU WROTE IT:</u>

If it is 2x+3y-7=2x+3y-7 then the solution is 1

IF THIS IS NOT WHAT YOU NEED, <em>PLEASE </em>COMMENT WITH MORE CONTEXT! :D
