3(x + 4) - 2y, if x = 5 and y = -3

OpenStudy (anonymous):

Just plug in the values you're given.

OpenStudy (anonymous):

3(5 + 4) - 2(-3)

OpenStudy (anonymous):

help me please

OpenStudy (anonymous):

distribute

OpenStudy (anonymous):

3(5) + 3(4) - 2(-3)

OpenStudy (anonymous):

11 -7 33 21 Whats the answer

OpenStudy (anonymous):

I gave you the simplified expression, calculate it to get the answer. It's not hard.

OpenStudy (anonymous):

33

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

cool cool

OpenStudy (anonymous):

What is the slope of the line represented by the following equation? 4x - y + 3 = 0

OpenStudy (anonymous):

Do you know slope-intercept form?

OpenStudy (anonymous):

nah

OpenStudy (anonymous):

Haha, you need to memorize that

OpenStudy (anonymous):

It's very simple

OpenStudy (anonymous):

y = mx + b

OpenStudy (anonymous):

m is the slope, b is the y-intercept

OpenStudy (anonymous):

so to get the slope for that problem, you just need to change it to slope-interecept form

OpenStudy (anonymous):

You want to move everything except the y to the right side
