Answer:
63
Step-by-step explanation:
-7 * -9 = 63
negative times negative is always positive:)
Answer:
After it is simplified you get b= - ax/1-c
Answer: If the original equation is y = 3x -4, the slope is 3.
Any equation of a line parallel to the line <u>y = 3x -4</u> will have a slope of 3.
Step-by-step explanation:
In slope-intercept form, y =mx + b the coefficient of x, m is the slope.
Here 3 is that value.
It is very unusual to have two equal signs in a question about slope.
I am not sure what to do with the <u><em>=8y + 1</em></u>
Is this supposed to be another equation in the system, missing a term?
The answer is 1/10 as shown in the picture below
To figure out the answer here, all you have to do is plug the given point into your equations and see if the result is true:
(4, 2) .... aka (x, y)
2 - 4 = 2
-2 = 2 ... this one is FALSE, as -2 doesn't equal 2, so already you can tell that the point won't be a solution, but still, check the second equation.
-3(4) - 2(2) = -8
-12 - 4 = -8
-16 = -8 .... this one is also false. (4, 2) is not a solution for this system of equations.
