Answer:

Solution given:

x-y=-8

we know that

slope intercept form is y=MX+c

we trying to make above equation like that

x-y=-8

x+8=y

<u>y=x+8</u> is a required slope intercept form.

Factor 3x3 + 27x2 + 60x.
Rashid [163]

Answer:

3x( x+5) (x+4)

Step-by-step explanation:

3x^3 + 27x^2 + 60x.

Factor out the greatest common factor

3x( x^2 +9x+20)

Now factor inside the parentheses

What two numbers multiply to 20 and add to 9

5*4 = 20

5+4 =9

3x( x+5) (x+4)

is 3x+4y=12 linear or nonlinear......is y=1/2x+6 linear or nonlinear......is y=4x to the power of 2 linear or nonlinear......is
Ilya [14]

3x+4y=12 is Linear.

y-1/2x+6 is Linear.

y=4x^2 is nonlinear.

y+2=|4| is linear.

y+6=4x is linear.

In order to tell whether an equation is linear or not, you have to first see if there is any variable^2 or more than ^1. If that is the case, it isn't linear. For example the equation x^2=4 or y^5=100 isn't linear. It also isn't linear if the equation is divided by X or Y.For example the equation 1/x=1 isn't linear or 1/y^2=5 isn't linear.

A question is also linear if you can write it in the form y=mx+b , 'm' meaning the slope of the equation and 'b' meaning the y-intercept of the equation.

What is sin45 degrees =20/r
alisha [4.7K]

Answer:

r = 28.28

Step-by-step explanation:

you already gave the equation: sin45°= 20/r

you wanna start by multiplying both sides by r. You do this so that your variable can be in the numerator and it will be easier to solve the equation:

r (sin45°) = 20

Now you divide both sides by sin45°, this will give you your final answer. For this, you have to put it in a calculator:

r = 28.28

P.S, good job on already knowing your equation... when i was learning this it took me a while to get eh hang of it :)

Oz makes lion food out of giraffe and gazelle meat. Giraffe meat has 16 grams of protein and 32 grams of fat per pound, while ga
Alex

Answer:

To minimize costs, the pounds of giraffe meat are 1,067 and the pounds of gazelle meat are 267.

Step-by-step explanation:

Let

x -----> pounds of meat of giraffe

y -----> pounds of meat of gazelle

we know that

16x+32y \geq 25,600 -----> inequality A

32x+16y \geq 38,400 -----> inequality B

C=x+2y ----> the function cost

using a graphing tool    

The solution of the system of inequalities is the shaded area (positive values of x and y between the two solid lines)

see the attached figure

Three vertices of the shaded area are (0,2,400), (1,067,267) and (1,600,0)

Substitute in the function cost and then compare the results

For (0,2,400)

C=0+2(2,400)=\$4,800   ---> It doesn't make sense, because lion food should contain giraffe meat and gazelle meat.

For (1,067,267)

C=1,067+2(267)=\$1,601

For (1,600,0)

C=1,600+2(0)=\$1,600 ---> It doesn't make sense, because lion food should contain giraffe meat and gazelle meat.

therefore

To minimize costs, the pounds of giraffe meat are 1,067 and the pounds of gazelle meat are 267.
