Answer:
12
Step-by-step explanation:
-12 = -3/4x + 3
-9 = -3/4x
-9 = (-3/4) times x
-9 = (-3/4) times 12
hope this helps! :)

Answer:
5a(6a-7) = 30a² - 35a
Explanation:
Before we begin, remember the following:
a(b+c) = ab + bc
Now for the given:
Assume that the first question mark is x and that the second question mark is y.
The expression now becomes:
(6a-x) * 5a = ya² - 35a
Distribute the 5a over the bracket and equate it with the right-hand side as follows:
5a(6a) - 5a(x) = ya² - 35a
30a² - 5ax = ya² - 35a
By comparison:
30a² = ya² ..............> This means that y = 30
-5ax = -35a
-5x = -35
5x = 35
x = 35/5
x = 7
Based on the above, the expression is:
5a * (6a-7) = 30a² - 35a
Hope this helps :)
y - 12 = -5(x + 12) is the required equation.
f(x) = -5x + 2
let f(x) = y
y = -5x + 2
y = -5x + 2
comparing it to y = mx + c
m = -5
The point slope form is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point. The equation of a line is an equation that is satisfied by each and every point on the line. This means that a linear equation in two variables represents a line.
The point slope equation formula is
y - y₁ = m(x - x₁)
Now the equation of line containing (-2,12) is

y - 12 = -5(x + 12)
