You sort of have to rearange it, but using math at the same time of course. :)

5y=2y+18
<span>5y-2y=2y+18-2y
</span>3y/3=18/3
y=6

Hoped I helped!

Find such m, that point (-2,4) is on line y=mx-3

Andreas93 [3]

Answer:

-3.5 ( or -7/2)

Step-by-step explanation:

we can substitute the point into this function to find out the answer

that is:

4 = m*(-2) -3

7 = m*(-2)

m = 7 / (-2)

m = -3.5

Prove that the two circles shown below are similar.

s344n2d4d5 [400]

The circles B and D are similar since the radius of the former is as twice as the radius of the latter.

<h3>Are the two circles shown in the figure similar?</h3>

By geometry we know that circles are defined by only one characteristic: radius. If two circles are similar, then the radii must be <em>different</em>. After a quick look at the figure, we conclude that the radii are $r_{B} = 4$ and $r_{D} = 2$ . Hence, the circles B and D are similar since the radius of the former is as twice as the radius of the latter.

Given the polynomial 6x3 + 4x2 − 6x − 4, what is the value of the coefficient 'k' in the factored form? 6x3 + 4x2 − 6x − 4 = 2(x

anastassius [24]

$6x^3+4x^2-6x-4 =\\ 2(3x^3+2x^2-3x-2) =\\ 2(x^2(3x+2)-1(3x+2))=\\ 2(x^2-1)(3x+2)=2(x+1)(x-1)(3x+2).$

So k=1.

If x-y doesn't equal 0 then x^2-y^2 / x-y =

NARA [144]

Recognize the differnce of 2 perfect squares

a²-b²=(a-b)(a+b)

so
$\frac{x^2-y^2}{x-y}=\frac{(x-y)(x+y)}{x-y}=(\frac{x+y}{1})(\frac{x-y}{x-y})=(x+y)(1)=x+y$
