Answer:

D

Step-by-step explanation:

A)

3(2) + 4(-2) = -2                    2(2)-4(-2) = -8

6 - 8 = -2                              4 + 8 = -8

Correct                                 Incorrect  

B)

3(6) + 4(-5) = -2                    2(6) - 4(-5) = -8  

18 - 20 = -2                            12 + 20 = -8

Correct                                 incorrect

C)

3(4) + 4(4) = -2

12 + 8 = -2

incorrect

D)

3(-2) + 4(1) =-2                        2(-2) - 4(1) = -8

-6 + 4 = -2                                 -4 - 4 = -8

Correct                                      Correct

Best way is process of elimination

What are the slope and the y-intercept of the linear function that is represented by the equation 8x-2y = 57
krok68 [10]

Answer:

slope(m)=4 and

y-intercept(c)=-5/2

Step-by-step explanation:

here,8x-2y=5

reducing it into slop intercept form we get,

2y=8x-5

or,y=8/2x+(-5/2)

or,y=4x+(-5/2)

comparing it with y=mx+c we get,

slope(m)=4 and

y-intercept (c)=-5/2

Someone please explain this it’s confusing me.
Nesterboy [21]

Answer:

x = 4 radical 3 / 3

Step-by-step explanation:

this is a 30-60-90 triangle

the side across from the angle 30 is L

the side across from the angle 60 is L√3

the side across from the angle 90 is 2L

we are given the side across from 60⁰ so we know that:

2 = L√3

we want to solve for L, so we must divide both sides by √3 (radical three)

2/√3 = L√3/√3

you would get 2/ √3 = L, because the radical three cancels out on the L side.

but you can't have a radical in the denominator, so you have to multiply 2/√3 by radical 3

2 times √3 and √3 times √3

you get 2√3/√9

radical nine can simplify

2radical3/3 or 2√3/3

we found L, but that would equal the thirty degree angle, not the 90, 90 = 2L

multiply the number infront of the radical by two and get

4√3/3

x=4 radical 3 divided by 3
