-4x = 3 - y

-4x/-4 = 3/-4 - y/-4

x = -3/4 + y/4

Write out the equation in Mx+b

Answers

Answer

y= 3/2 x - 2

Step-by-step explanation:

so you have to find the slope which would be

m =

y2 - y1

x2 - x1

then you find you points that you are using (2, 1) and (0, -2)

when you plug it in it is

-2-1

0-2

you simplify the numbers and get rid of the negatives to get m=3/2 x

then your y intercept is where your line meets the y axis or wherever x=0

so your y intercept is (0, -2) so the b = -2

the equation for the cross section of a parabolic satellite television dish is y=1/50x^2 measured in inches, how far is the focus from the vertex of the cross section?

Answers

Answer:

12.5 inches

Step-by-step explanation:

Given the equation for the cross section of a parabolic satellite TV dish:

y=1/50x^2

Equation of a parabola :

(y - k) = 1/4p * (x - h)^2

Distance of the focus from the Vertex = p

Comparing both equations :

1/4p * (x - h)^2 = 1/50 * x^2

4p = 50

Divide both sides by 4

4p/4 = 50/4

p = 12.5 inches

A rectangular picture frame is 3inches wide by 5 inches long.
Tamara needs a larger picture frame that is 12 inches wide, how
long must the picture frame be so that is proportional to the
smaller frame?

Answers

Answer:

20in

Step-by-step explanation: If the smaller frame is 3 by 5in long then the larger frame will by 12 by 20in becuase 3*4=12 so 5*4=20

3/4=12/40

Answer: 20 inches long.

Step-by-step explanation:

The Rectangular frame which Tamara already has is 3 inches by 5 inches. The larger one happens to be 12 inches by X inches. We can find the scale of the new Frame by dividing the new value we are provided with by the initial one. In this case, 12 (large frame) divided by 3, or 4. This means that the dimensions of the large Frame are 4 times greater than the smaller one. If this is to be the case, the length is 4 times larger than the original, and 5 x 4 = 20.

Step-by-step explanation:

Given the expression

[tex]\mathrm{Apply\:radical\:rule}:\quad \sqrt[n]{a}=a^{\frac{1}{n}}[/tex]

[tex]\sqrt[3]{\left(-0.05\right)^{24}}=\left(\left(-0.05\right)^{24}\right)^{\frac{1}{3}}[/tex]

What is the equation for the points (-2,3) (1,9) on a graph

Answers

9514 1404 393

Answer:

y -9 = 2(x -1) . . . point-slope formy = 2x +7 . . . . slope-intercept form2x -y = -7 . . . . standard form

Step-by-step explanation:

Perhaps you want the equation of the line that goes through these two points.

The slope of the line can be found using the formula ...

m = (y2 -y1)/(x2 -x1)

m = (9 -3)/(1 -(-2)) = 6/3 = 2

We can use one of the points to write the equation in point-slope form:

y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)

For slope 2 and point (1, 9) the equation is ...

y -9 = 2(x -1) . . . . equation in point-slope form

We can eliminate parentheses and get y by itself to put the equation into slope-intercept form.

y -9 = 2x -2

y = 2x +7 . . . . . . equation in slope-intercept form

With a little further rearranging, we can put this into standard form. We can get that by adding -7-y to both sides of the equation.

2x -y = -7 . . . . . equation in standard form

Brian and Emily are testing different paper airplane designs to see which will allow a plane to go the farthest. Emily folds her plane and attaches a paperclip to the front of it. After she throws the plane, it travels about fifty feet and then starts to fall to the ground. Why does the plane eventually fall to the ground?

The force of air resistance stops acting on the plane.

The plane was not designed to carry a load like a paperclip.

The force of gravity is greater than the force keeping the plane in the air.

The paperclip creates a magnetic force that attracts the plane to the ground.

and actually answer it, answers will be reported if you put random letters.

A nutrition bar includes fat and protein in the ratio of 3:5. There are a total of 24 grams of fat and protein combined in the bar. If there are 9 calories per gram of fat and 4 calories per gram of protein, how many calories from fat and how many calories from protein are in the nutrition bar?

Answers

Let, amount of fat is 3x .

So, amount of protein is 5x .

It is given that sum of fat and protein is 24 grams.

3x + 5x = 24

8x = 24

x = 3 grams

Amount of fat is, F = 3×3 = 9 grams .

Amount of protein is, P = 5×3 = 15 grams.

Calories in fat, F = 9×9 = 81 calories .

Calories in protein, P = 15×4 = 90 calories .

Therefore, calories from fat and protein is 81 and 90 respectively.

Hence, this is the required solution.
