Answer:u=19/7 or 2.714286 or 2 5/7
Step-by-step explanation:
−14u+32=−6
Step 1: Subtract 32 from both sides.
-14u+32-32=-6-32
-14u=-38
Step 2: Divide both sides by -14.
-14u/-14=-38/-14
U=19/7
X<1999
as it means every year before 1999
Answer:
Perimeter = 
feet
Step-by-step explanation:
The perimeter of a triangle is sum of all the three sides. To get the perimeter (the expression) we add the expressions of all the three sides and do algebra:
12x + 15x + 4 + 10x + 3x^2 - 8
3x^2 + 12x + 15x + 10 x + 4 - 8 [rearranged]
3x^2 + 37x - 4
Hence, the perimeter is feet
The answer should be (C):y=(-3/7)x+3 because:
if you use the slope formula: (Y2-Y1)/(X2-X1) it would look like this:
(0-3)/(7-0) and the slope of the line would be -3/7
then using the slope you just found, plug it into the y=mx+b equation along with one set of coordinates to find b (the y-intercept):
y=mx+b
0=(-3/7)(7)+b
b=3
SO, overall if you put the slope (m) and the y-intercept (b) that you found together, you get the line formula of y=(-3/7)+3
