Which method is best using this equation 4x-2y=-2,-5x+6y=-15 and why

1 answer:

8 0

I think that using the elimination method is the best, because it is the only method that I use when solving these types of equation. For example, for these two equations, you need to multiply one of the equations by a certain number so that you'd be able to find x and y. The elimination method is the method that tells you to do that. It is also the easiest method.

~Hope I helped!~

Jill is factoring the expression 13xy-52y. Her work is shown below.

Factors of 13xy: 1, 13, x, y

Factors of 52y: 1, 2, 26, 52, y OOPSIE she forgot 4,13

GCF: y

Factored expression: y(13x-52) 13y (x-4)

Answer:

$Average\:Rate\:Change=-59.4$

Step-by-step explanation:

The given function is $f(x)=120(0.1)^x$ .

We want to find the average rate of change of this function from $x=0$ to $x=2$ .

This is given by:

$Average\:Rate\:Change=\frac{f(2)-f(0)}{2-0}$

This implies that;

$Average\:Rate\:Change=\frac{120(0.1)^2-120(0.1)^0}{2-0}$

$Average\:Rate\:Change=\frac{120(0.1)^2-120}{2}$

$Average\:Rate\:Change=\frac{120((0.1)^2-1)}{2}$

$Average\:Rate\:Change=\frac{60(0.01-1)}{1}$

$Average\:Rate\:Change=60(-0.99)$

$Average\:Rate\:Change=-59.4$

answer: right

reason: because you are talking about the x axis so if you go left that would be a negative and you cant go up and down bc that's the y axis so the only way to go is right

hope this helped
