Answer:

y=13-1/2x

Step-by-step explanation:

subtract 2x on both sides

-4y=52-2x

the divide by -4 on both sides

y=13-1/2x

Write the equation of the line that passes through the points (2,−8) and (1,7). Put your answer in fully reduced point-slope for
ValentinkaMS [17]

Point-slope form of equation is: y - 7 = -15(x-1)

Step-by-step explanation:

Given points are:

(2,-8) and (1,7)

First of all we have to calculate the slope of the line

so,

m=\frac{y_2-y_1}{x_2-x_1}\\= \frac{7-(-8)}{1-2}\\=\frac{7+8}{-1}\\=\frac{15}{-1}\\= -15

Point-slope form is given by:

y-y_1 = m(x-x_1)

Putting the value of slope

y-y_1 = -15(x-x_1)

We can put any one of two given points in the equation to find the final form of point-slope form

So

Putting (1,7) in the equation

y - 7 = -15(x-1)

Hence, point-slope form of equation is: y - 7 = -15(x-1)

Reducing and simplifying

y - 7 = -15(x-1)\\y-7 = -15x+15\\y-7+7 =-15x+15-7\\y = -15x+8\\15x+y = 8

The figure is made up of 2 hemispheres and a cylinder. What is the exact volume of this figure? 126π in.³ 378π in.³ 396π in.³ 64
bogdanovich [222]
The two domes or hemispheres simply have the area of a complete sphere with the same diameter.  So the total area is the area of a sphere and a cylinder...

as=(4p3^3)/3, ac=10p3^2

A= 36p+90p=126p in^3
