Answer: 4xy+6x+2x^2

Step-by-step explanation:

4xy-2x+2x^2+8x

we can combine the terms that only have an x (Ax for any number A)

Nesterboy [21]

Answer:

14,130 feet³

Step-by-step explanation:

2r=d

2r=30

r=15

Formula for the volume of a cone is: \frac{1}{3} *b*h

\frac{1}{3} *π*r²*h=

\frac{1}{3} *3.14*15^{2} *60=\\

\frac{1}{3} *3.14*225*60=

\frac{1}{3} *3.14*13,500=\\

\frac{13,500}{3} *3.14=\\

How would I graph this?
elena55 [62]

y\leq 2x-5

↝ x-intercept

2x-5=0\\2x=5\\x=\frac{5}{2}

↝ y-intercept

y = -5

↝ y\leq 2x-5 means that the shade/area is below the graph as shown in the first picture.

y\leq -\frac{1}{2}x-3

↝ x-intercept

-\frac{1}{2}x-3=0\\-x-6=0\\-x=6\\x=-6

↝ y-intercept

y = -3

↝ Since it's "≤" therefore. The shade/area is below the graph. For second picture.

First picture is first inequality

Second picture is second inequality.
