So because the factors of the equation are (x-2), (x+3) and (x-3), you set them equal to zero and you get x=2, -3, and 3
You just change the mixed number into an improper fraction.
4 3/5
5x4=20
20+3=23
23/5
49,400-20,000=29400
29400/24=1225 average miles per month
Answer:
y = 4
x = -6
Step-by-step explanation:
multiply first equation by 3
3×(5x+4y)= -14 ➡ 15x + 12y = -42
multiply second equation by -5
-5×(3x+6y)= 6➡ -15x -30y = -30
now add both equations up
15x +12y -15x -30y = -42 -30 (15x will eliminate -15x)
-18y = -72
y = 4 use this to find value of x
3x + 6×4 = 6 ➡ ex = -18 ➡ x = -6
Answer:
y = 2x + 0
Step-by-step explanation:
the formula is y = mx + b
m = slope = change in y/change in x = (84 - 76)/(42 - 38) = 2
Slope is 2.
b is the y-intercept, which is the coordinate when x = 0. To find b, substitute any coordinate from the table. Let's use (38, 76)
y = 2x + b
76 = 2(38) + b
76 = 76 + b
b = 0
So the equation is y = 2x + 0
