Answer:
-1 and 9
Step-by-step explanation:
To solve the quadratic, factor and set its factors equal to 0. Factoring is the action of breaking up a polynomial into pieces which multiply to make it. The factors are found by multiplying numbers to make C and add to B of
.
Here c = -9 and b = -8. The numbers -9 and 1 multiply to -9 and add to -8. These are the factors (x-9)(x+1).
Set each equal to 0 and solve for x.
x-9 = 0
x = 9
x+1 =0
x = -1
On solving the linear system, for the value of y = 15, the value of x is 200. The correct option is D.
<h3>What is the linear system?</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
The linear equation is shown below.

The equation can be written as

For y = 15, the value of x will be.

The value of x is 200.
Thus, option D is correct.

we can find the answer to this problem by thinking about it logically for a minute:
we know that she assigned "x" homework problems on Monday, so,
x=Monday
we also know that she assigned 13 more problems on Tuesday, so,
13=Tuesday
over the course of the two days she assigned a total of 23 homework problems.
to get the answer of how many problems she assigned on Monday, we have to do the total number of problems she assigned(23) minus the number of problems we know she assigned on Tuesday(13), so,
23-13=10
she assigned 10 problems on Monday.
Answer:
sin(2θ) = 24/25
Explanation:
In order to find the value of sin 2θ, first, recall the double-angle formula for sine.

From the right-triangle:

Substitute these values into the double-angle formula obtained earlier.

The exact value of sin(2θ) is 24/25.
