60x - 12 = 14x^2 + 14x

Subtract 60x & Combine

-12 = 14x^2+14x-60x
-12= 14x^2-46x
Add 12
0= 14x^2-46x-14

12(5x-1)=7(2x+2)
Distribute 12 and 7

60x-12=14x+14
Add 12 to each side

60x=14x+26
Subtract 14x on each side

46x=26
Divide by 46 on each side

x=26/46 or x=13/23

Type the correct answer in the box. Use numerals instead of words.

Karo-lina-s [1.5K]

Answer:

Step-by-step explanation:

A line that passes through the point (x,y), with a y-intercept of b and a slope of m, can be represented by the equation $y = mx + b$ .

If a line has the slope of -0.5, then m=-0.5 and the equation of the line is

$y=-0.5x+b$

This line passes throughthe point (10,1), then the coordinates of this point satisfy the equation of the line:

$1=-0.5\cdot 10+b\\ \\1=-5+b\\ \\b=1+5\\ \\b=6$

and the equation of the line is

$y=-0.5x+6$

Since b=6, the y-intercept of the line is 6.

What number is q in the problem -8-q-10q=-9q+6

uranmaximum [27]

For this question you can say:
-8 -11q = -9q +6
so now you can add +9q on both sides and +8 on both sides of the equation:
-11q + 9q = 8 + 6
-2q = 14
q = 14/-2
q = -7 :)))
