Answer:
Infinite solutions.
Step-by-step explanation:
-4x = y + 3......(1)
y = -4x - 3........(2)
Rearranging equation (1)
y = -4x - 3 ------(3)
Adding (2) and (3) we get
0 = 0.
The original equations are identical and their graph will be the same straight line.
Any point on the line is a solution of this system, so there are infinite solution.
Answer:
-11/12
Step-by-step explanation:
Answer: 16.54 liters an hour
Step-by-step explanation:
A month into hours is 730.001 hours
12080 / 730.001 = 16.54 liters an hour.
Answer:
y = (x - 4)(x + 9).
Step-by-step explanation:
Intercept form is y = a(x + b)(x + c)
y = x^2 + 5x - 36.
Here the coefficient of x^2 is 1 so a = 1.
To find b and c we need 2 numbers whose product is -36 and whose sum = +5. These are + 9 and - 4 so the answer is:
y = (x - 4)(x + 9).
Answer:
The first step is to slove the numbers in the brackets
Step-by-step explanation:
[(x+7) x -2] / 4 = 7
-2(x+7) / 4 = 7
-2x-14 / 4 = 7
-2x-14 = 28
-2x = 42
x = -21
