Answer: c

Step-by-step explanation: Y=4 will result in a straight line across 4 from the y axis. Y=4x is a linear equation for which result in a straight constant like. Y=4x2 represents a parabola equation and will create one. Y=4x3 represents a cubic equation

Need help asap with b and c!!! plz help for a cookie :)
Debora [2.8K]
You can think of this question like the photo attached above.

Hi!

I think for b, the answer would be:

You can construct an angle that is one fourth the measure of angle JKL, by dividing angle either angle MKL or JKM in half.
This is because one-fourth is also equal to one quarter (1/4). If you split angle JKL into 4 equal angles, you would have an angle that is one-fourth the measure (original angle) of angle JKL.

I think for c, the answer would be:

You can construct a 15 degree angle from a given 60 degree angle, by dividing the 60 degree angle into 4 equal angles.
This would work, because each of the 4 angles would be 15 degrees.

Hope this helps! Best of luck!

What is the product of 2x + y and 5x – y + 3? x2 + xy + x + y2 + y
miskamm [114]

Answer: 10x^2+3xy+6x-y^2+3y

Step-by-step explanation:

You need to remember the Product of powers property:

(a^m)(a^n)=a^{(m+n)}

Then, knowing this property, now you have to apply the Distributive property. So:

(2x+y)(5x-y+3)=\\\\=(2x)(5x)-(2x)(y)+(2x)(3)+(y)(5x)-(y)(y)+(y)(3)\\\\=10x^2-2xy+6x+5xy-y^2+3y

Finally, to simplify this expression, you need to add the like terms.

Therefore, you get that the product is:

=10x^2+3xy+6x-y^2+3y
