Answer:

A

Step-by-step explanation:

Remember, the equation of slope-intercept is y=mx+b

We see that for A, that the first equation's slope is -2/3. That means we are going to move down two and left five. The reason why we are going down is that the slope is negative. We also know that our y-intercept is -4. So we first plot the point (0,-4). Then we move down two and left five. We apply the same knowledge with the second equation. When we plot both equations, we get the same exact graph as the picture.

HEY THERE!!!!

The correct answer is 34°

They are supplementary angles (connect with a straight line) which means that their angles add up to 180° so:

180 = x + 156

34 = x

What is the center of the circle with the equation x2 + y2 – 10x – 11 = 0 ?

Kaylis [27]

Rearrange to standard form:-

x^2 - 10x + y^2 = 11
(x - 5)^2 - 25 + y^2 = 11
(x - 5)^2 + y^2 = 36

Center of circle = (5, 0) and radius = sqrt36 = 6

Factor the expression. 35g^2 – 2gh – 24h^2

stiks02 [169]

Option C: $(7 g-6 h)(5 g+4 h)$ is the correct answer.

Explanation:

The given expression is $35 g^{2}-2 g h-24 h^{2}$

We need to determine the factor of the expression.

Now, let us break the given expression into two groups.

Hence, we get,

$35 g^{2}+28 g h-30 g h-24 h^{2}$

Simplifying, we get,

$\left(35 g^{2}+28 g h\right)+\left(-30 g h-24 h^{2}\right)$

Let us factor out 7g from the term $\left(35 g^{2}+28 g h\right)$

Hence, we have,

$7 g(5 g+4 h)+\left(-30 g h-24 h^{2}\right)$

Similarly, let us factor out -6h from the term $\left(-30 g h-24 h^{2}\right)$

Thus, we have,

$7 g(5 g+4 h)-6 h(5 g+4 h)$

Now, we shall factor out the term $5g+4h$ , we get,

$(7 g-6 h)(5 g+4 h)$

Thus, the factorization of the given expression is $(7 g-6 h)(5 g+4 h)$

Therefore, Option C is the correct answer.
