4(u+3)+3u=-2
distribute: 4u+12+3u=-2
simplify: 7u+12=-2
isolate the variable: 7u=-14
divide: u=-2
check answer: 4(-2+3)+3(-2)=-2
-8+12-6=-2
-2=-2
therefore, u= -2

Answer:
9
Step-by-step explanation:
BECAUSE 54 : 2,3,9. and 45 : 5,9. so the greatest common factor is 9
Answer:
y = (2/3)x + 4 2/3
Step-by-step explanation:
For reference, a linear function has an equation of y = mx + b
The first thing we're going to do is use the slope formula,
or rise over run. In this case that looks like:
(-2-4) - (8 - -1)
-2 -4 comes out to - 6, and the denominator comes out to 9.
6/9 is equal to 2/3, which is our m or slope value.
Next we want to find the b value, or our y-intercept. To do that we'll plug one of the points into the equation with our new-found slope:
4 = (2/3)-1 +b
4 = -2/3 + b
4 2/3 = b
That means our complete equation is:
y = (2/3)x + 4 2/3
OR
y = (2/3)x + 14/3 (equivalent but an improper fraction rather than a mixed fraction).
