Answer:

-4

Step-by-step explanation:

In order to get from point -1, 8, to point 2, -4, you would have to go down 12 and right 3, which would be 12/-3, which would simplify to -4

Answer:

Option B is the correct option

Step-by-step explanation:

Let the points be A and B

A ( -1 , 8 ) -----> ( x1 , y1 )

B ( 2 , -4 ) -----> ( x2 , y2 )

Now, let's find the slope of the line:

$\frac{y2 - y1}{x2 - x1}$

plug the values

$= \frac{ - 4 - 8}{2 - ( - 1)}$

Calculate the difference

$\frac{ - 12}{2 - ( - 1)}$

When there is a (-) in front of an expression in parentheses , change the sign of each term in expression

$\frac{ - 12}{2 + 1}$

Add the numbers

$= \frac{ - 12}{3}$

Reduce the fraction with 3

$= - 4$

Hope this helps..

Solve the system by either elimination or substitution

Alex_Xolod [135]

The correct answer is A: x=2 and y=-3. Either method would work, but for example, let's use elimination. If you multiply the second equation by 5, you get: 10x +5y = 5. When you add both equations, you can then cross out both y terms. You are left with one equation that reads: 13x=26. Solving for x gives you 2. You can substitute 2 in for x in either equation and you will receive -3 for your y value.

Rewrite the following equation in log form: 2^2 = 4

Finger [1]

We have to write

$2^2 =4$

In log form

To convert exponential equation to log equation, we have to use the following rule $If \ a^b = c, \ then \ b=log_{a} c$

So we will get

$If \ 2^2 =4, \ then \ 2 = log_{2} 4$

$log_{2}4=2$

And that's the required log form .

Help me answer this please:)

Dmitrij [34]

Answer:

A and B

Step-by-step explanation:

$\frac{7x+6}{2}\leq 3x+2 < ==multiply\ both\ sides\ by\ 2\\2(\frac{7x+6}{2}\leq 3x+2)\\\\7x+6\leq6x+4 < ==subtract\ -6x\ from\ both\ sides\ \\-6x \ \ -6x\\\\x+6\leq4 < ==subtract\ 6\ from\ both\ sides\\-6 \ \ \ -6\\\\x\leq-2 < ==answer\ should\ be\ anything\ less\ than\ or\ equal\ to\ -2$

Now, look at your answer choices, which options are less than or equal to -2?

x ≤ -2, Check your answers:

A. -3 ≤ -2?

This statement is correct (-3 is < -2)

B. -2 ≤ -2 <== our original answer

This statement is correct (-2 is = to -2)

C. -1 ≤ -2

This statement is incorrect (-1 is > -2, not ≤ -2)

D. 0 ≤ -2

This statement is incorrect (0 is > -2, not ≤ -2)

E. 1 < -2

This statement is incorrect (1 is > -2, not ≤ -2)

Therefore, the correct options are A and B

Hope this helps!
