Answer:

-9

Step by step explanation:

it can also be written as; 18 over x is equal to -2 over 1

you cross multiply to get 18 = -2x

then multiply through with -2; 18 over -2 = -2x over -2

you cross out; -2 cancels itself and -2 goes into 18 , -9 times

Therefore; the answer is -9

Solve the inequality 2c/3+1>7
beks73 [17]

Answer:

c > 9

Step-by-step explanation:

(2c/3) + 1 > 7     subtract 1 from both sides

2c/3 > 7 -1

2c/3 > 6  (multiply both sides by 3)

2c > 6(3)

2c>18    (divide both sides by 2)

c > 18 / 2

c > 9

the point slope form of the equation of the line that passes through (-4 -3) and (12, 1) is y - 1 = 1/4 (x - 12). what is the st
Sergeeva-Olga [200]

Standard Form is ...

ax + by = c

where a ≥ 0, b > 0 (if a=0), and {a, b, c} are mutually prime integers (unless irrational numbers are involved).

You can get there from where you're starting in a couple of steps. Multiply by the least common denominator of any fractions. (Here, you multiply by 4.) Then put the variable terms on the opposite side from the constant term. Make sure the leading coefficient is positive.

... 4y -4 = x -12

... x -4y = 8 . . . . add 12-4y

Which is the equation of a line that is parallel to the line represented by y = 7/6x + 4?
kipiarov [429]

Answer:

The answer that you are looking for is basically y = 7/6x + any number besides 4.

Step-by-step explanation:

So, two parallel lines are two lines that will never intersect. To have that, both of the lines have to have the same exact slope. But they cannot have the same y-intercept because that would change it from parallel to infinite solutions.

I hope that I helped.
