Find the Equation of a line that has a slope of 5 and passes through ( 2, 8 ). Detailed answers would be appreciated.

First you need to fill in the given information into slope intercept form, so y=mx+b. Filling in what you know it would be 8=5(2)+b then just solve it from there like you would a normal equation to find your answer for b. Then plug in the answer you get for b into the original equation. Is this helpful or do you need me to walk you through more steps?

Which statement is true?

kvasek [131]

For each inequality, multiply the individual fractions to get the same denominator. Then you can just compare the numerators.

For example:
5/8<2/3
15/25<16/24 is true

Helpppp plssssss I need to get my grade up in math

Answer: 1.25 square feet

This converts to the improper fraction 5/4

===========================================================

Explanation:

The area of the triangle on the left is base*height/2 = 0.5*2/2 = 0.5 square feet. Note that 1/2 = 0.5

The area of the triangle on the right side is base*height/2 = 0.2*3/2 = 0.75 square feet. This converts to the fraction 3/4

Add up the two results: 0.5+0.75 = 1.25 square feet

-----------

If you need the answer as an improper fraction, then,

1.25 = 1 + 0.25

1.25 = 1 + 1/4

1.25 = 4/4 + 1/4

1.25 = (4+1)/4

1.25 = 5/4

Find the mass of the triangle with vertices (1; 0; 0), (0; 2; 0), (0; 1; 1) if the density function is given by (x; y; z)

Luda [366]

Answer:

$=\frac{17}{3}$

Step-by-step explanation:

Density of a function is $\rho(x,y)=x^{2} +y^{2}$

I have drawn the right angle triangle for visualization

equation for the line passing through (1,0) and (0,4) is

$\frac{y}{4} =\frac{x-1}{-1}$

$y=4-4x$

= $\int_{0}^1\int_{0}^{4-4x} (x^{2}+y^{2})dydx$

= $\int_{0}^{1}(x^{2}+\frac{y^{3} }{3})dx$

= $\int_{0}^{1}(x^{2}(4-4x)+\frac{1}{3}(4-4x)^{3} )dx$

= $\int_{0}^{1}(\frac{-76}{3}x^{3} +68x^{2}-64x^{}+\frac{64}{3} )dx$

= $=(\frac{-76}{3} \frac{x^{4} }{4})+\frac{68}{3}x^{3}-32x^{2}+\frac{64}{3}x^{})$

$=\frac{17}{3}$

To which family does the function y= (x+2)^1/2 +3 belong? A.quadratic B.square root C.exponential D.reciprocal

Alex Ar [27]

It belongs to the square root family. Your answer is B. Why the square root family? Because $y = (x+2)^{\frac{1}{2}} +3$ can be written as $y = \sqrt{(x+2)} + 3$

When you raise to 1/2 or 1/3 it is like saying the square root or the cube root.

Write an equation of the line that passes through the point (3,-2) with slope -2.

Virty [35]

Answer:

y + 4 = -2(x - 3)

Step-by-step explanation:

Use the point-slope formula y - k = m(x - h). Substitute -2 for k and 3 for h, as well as -2 for m:

y + 4 = -2(x - 3).
