Answer:

19

Step-by-step explanation:

add 12 to both sides to get x = 19

12 + 12 = 0 since your getting rid of the constants and 12 + 7 = 19 so x = 19

Use the opposite operation in which its formed in

For example 3x = 18

you would have to multiply 3 by x right? So the opposite operation of that is divide by 3 since you dont know the value of x so do the known value which is the number 3 once you divide 18 by 3 you get 6 so put 6 on the right side and keep the equal sign between them to get x = 19.

Write an equation in slope-intercept form for the line with slope 1/4 and y intercept -4. Then graph the line​
quester [9]

Answer:

Step-by-step explanation:

slope intercept form is y = mx + b

b is the y intercept ( crossing y axis value)....     by inspection   b = -4

m is the slope of the line,  Slope = m = 1/4      note: the slope is positive

the slope equals the 'rise' over 'run'  

if the line moves up the slope is positive, if the line moves down the slope is negative

the rise is how many y units does the line go 'up' or 'down'

the run is how many x units does the line go 'left' or 'right'

the rise = 1  Y unit

the run = 4 X units

y = mx + b    m =1/4  b = -4

y = (1/4)x + (-4)

y = (1/4)x - 4

graph a line stating at y = -4 and going up (rising) to the right ONE Y Unit for  every FOUR X units (the run)
