If y= -2x-1 and x= -2 what is the answer?

2 answers:

Y = -2x -1 and x = -2

Simply plug in -2 for x in our given equation :)

y = -2(-2) - 1

Simplify.

y = 4 - 1

Simplify.

So, y =3

x = -2, y = 3

To check our work, simply plug -2 in for x, and 3 in for y.

y = -2x - 1

(3) = -2(-2) - 1

Simplify.

3 = 4 - 1

3 = 3

Therefore, x = -2, y = 3

~Hope I helped!~

Answer:

D, E, C, A, and B.

Step-by-step explanation:

We wish to solve the equation:

$2(x-3)+7-3x=11$

Let’s go through this step-by-step.

1) Distributive Property:

$2x-6+7-3x=11$

2) Commutative Property of Addition (we rearrange them):

$2x-3x-6+7=11$

3) Combined Like Terms:

$-x+1=11$

4) Addition Property of Equality* (we add <em>-1</em> to both sides):

$-x=10$

5) Multiplication Property of Equality (we multiply both sides by -1):

$x=-10$

So, our sequence is:

D, E, C, A, and B.

*A better choice would’ve been the Subtraction Property of Equality, but both are equally fine.

Marina86 [1]

Answer:

$d=10$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step 1: Define endpoint coordinates

(2, 5)

(-6, -1)

Step 2: Substitute and Evaluate

$d=\sqrt{(-6-2)^2+(-1-5)^2}$

$d=\sqrt{(-8)^2+(-6)^2}$

$d=\sqrt{64+36}$

$d=\sqrt{100}$

$d=10$

A supervisor records the repair cost for 25 randomly selected dryers. A sample mean of $93.36 and standard deviation of $19.95 a

Feliz [49]

Answer:

The 98% confidence interval for the mean repair cost for the dryers is (83.4161, 103.3039).

Step-by-step explanation:

We have a small sample size n = 25, $\bar{x} = 93.36$ and s = 19.95. The confidence interval is given by $\bar{x}\pm t_{\alpha/2}(\frac{s}{\sqrt{n}})$ where $t_{\alpha/2}$ is the $\alpha/2$ th quantile of the t distribution with n - 1 = 25 - 1 = 24 degrees of freedom. As we want the 98% confidence interval, we have that $\alpha = 0.02$ and the confidence interval is $93.36\pm t_{0.01}(\frac{19.95}{\sqrt{25}})$ where $t_{0.01}$ is the 1st quantile of the t distribution with 24 df, i.e., $t_{0.01} = -2.4922$ . Then, we have $93.36\pm (-2.4922)(\frac{19.95}{\sqrt{25}})$ and the 98% confidence interval is given by (83.4161, 103.3039).
