Answer:
y=-3x-1
Step-by-step explanation:
12x+4y=-4
Slope intercept y=mx+b
Subtract 12x from both sides
4y=-4-12x
Divide each side by 4
y=-1-3x then just reorder to match slope intercept form
y=3x-1
Answer: -30r + 15
Step-by-step explanation:
first, we multiply the parenthesis by 20.
-20 x 1.5r + 20 x 0.75
then, we multiply/calculate.
-30r + 15
Answer:
The equivalent function: 
Step-by-step explanation:
The x-intercepts of the given function on the graph can be obtained by equating the function to zero.
This is because on the x-axis, the y-coordinate is zero.

The function that has the same x-intercepts on the graph from the given options is:

Alternate Method:
The answer can also be obtained by factorizing the question.
Answer:

Solution: 105
Step-by-step explanation:
You multiply 15 and 7 to get your solution.
Answer:
The greatest common factor of this would be 3x^2y
Step-by-step explanation:
In order to find this, first find the greatest common factor of the coefficients. Since 3 goes in evenly to both 15 and -18, then we know that it is a common factor.
From there we need to find the number of x's. Since the first term only has 2 x's and the second has 3, we take the lowest number. (x^2)
And since the first term has 3 y's and the second has just 1, we take the lowest number (y).
