Answer:
y = -
x - 1
Step-by-step explanation:
First, we can put the equation into y = mx + b form:
2x + 5y = 10
5y = -2x + 10
y = -
x + 2
Now, we know the slope is -
. A parallel line will have the same slope.
So, we can plug in the point (-5, 1) into the equation y = -
x + b to find b:
1 = -
(-5) + b
1 = 2 + b
-1 = b
So, the equation will be y = -
x - 1
Answer:
-3c^2 +6
Step-by-step explanation:
The equation will be an identity (0=0) when M is equal to the contents of the parentheses. That polynomial can be used directly, or it can be simplified by combining the c^2 terms.
The contents of parentheses simplify as follows:
... (4c^2 -7c^2 +6) = (c^2(4 -7) +6) = (-3c^2 +6)
Answer:
(3)(x+7)(x-1)
Step-by-step explanation:
3x^2+18x-21
Let's start by taking 3 out of the equation.
3(x^2+6x-7)
Now, when we factor, we need to find two numbers that add up to 6 and multiply to -7.
The numbers would be 7 and -1.
So the factored form of this would be:
(3)(x+7)(x-1)
Answer:
y= 4x +3
Step-by-step explanation:
slope= rise over run
y-intercept = where the line hits the y axis
