Slope m= (y2-y1)/(x2-x1)=(8-0)/(2-(-2))=8/4=2

y=mx+b
y=2x+b
Take the point (-2,0)
0=2*(-2)+b
b=4
y=2x+4=2(x+2)

Answer is A. y=2(x+2)

the volume of the cone is 270πcm³. the height of the cone 10cm. work out the volume of the solid shape. give your answer in term
exis [7]

Answer:

The volume of a 3 -dimensional solid is the amount of space it occupies.  Volume is measured in cubic units ( in3,ft3,cm3,m3, et cetera).  Be sure that all of the measurements are in the same unit before computing the volume.

The volume V of a cone with radius r is one-third the area of the base B times the height h .

V=13Bh  or  V=13πr2h,  where  B=πr2

Note : The formula for the volume of an oblique cone is the same as that of a right one.

The volumes of a cone and a cylinder are related in the same way as the volumes of a pyramid and a prism are related. If the heights of a cone and a cylinder are equal, then the volume of the cylinder is three times as much as the volume of a cone.

A 12-inch cheese pizza at neighborhood pizza costs $9.95 and each additional topping is $1.00. the same size pizza at downtown p
Viefleur [7K]
Let us write an equations 

1st pizza place costs 9.95 + x dollars, where x is the number of toppings 
2nd pizza place 6.95 + 1.5 y dollars, where y is the number of toppings

We are interested when they are equal: 

9.95 + x = 6.95 + 1.5y
3= 1.5y - x
As the questions asks for the same ammount of toppings, x=y

3= 1.5y - x this becames
3=0.5 x
x=6

Lets check 
9.95+6=15.95
6.95+6*1.5=15.95 

So the answers is 6

Solve for x please help
34kurt

Answer:

x = 9

Step-by-step explanation:

By remote exterior angle theorem:

(12x + 14)\degree = (1 + 5x) \degree+ 76 \degree \\ 12x + 14 = 1 + 5x + 76 \\ 12x - 5x = 77 - 14 \\ 7x = 63 \\x =  \frac{63}{7}  \\ \huge \red{ \boxed{ x = 9}}
