Answer:

C and E

Step-by-step explanation:

I just took the test and got a 100%  :)

This question is based on the system of equation. Therefore, the correct options are (C) i.e. y=-1/6x+3 and (E) i.e.  y = 1/2x-1, are the equations of solution to the system is (6,2).

Given:

The solution to the system is (6,2).

We need to select all the equations that could be the other equation in the system.

For solving this question, we will be putting the given co-ordinates in the  given options and check.

A. y = - 3x

Putting the co-ordinates (6,2).

We get,

2 [tex]\bold{\neq}[/tex] -18

B. y=-3/2x+6

Putting the co-ordinates (6,2).

We get,

2 [tex]\bold{\neq}[/tex] -3

C. y=-1/6x+3

Putting the co-ordinates (6,2).

We get,

2 = 2

D. y=2/3x-1

Putting the co-ordinates (6,2).

We get,

2 [tex]\bold{\neq}[/tex]3

E. y=1/2x-1

Putting the co-ordinates (6,2).

We get,

2= 2

F. y=4x-2

Putting the co-ordinates (6,2).

We get,

2[tex]\bold{\neq }[/tex] 22

Therefore, the correct options are (C) i.e. y=-1/6x+3 and (E) i.e.  y=1/2x-1, are the equations of solution to the system is (6,2).

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

m=

-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

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

Answer:

As

so option D is correct.                    

Step-by-step explanation:

Given the expression

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

[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]

[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc}[/tex]

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

[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(-a\right)^n=a^n,\:\mathrm{if\:}n\mathrm{\:is\:even}[/tex]

                  [tex]=0.05^8[/tex]

Hence, the simplification will be:

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.

Answer:

We add 25 and subtract 25 to complete the square.

[tex](x+5)^{2}-38=0\\[/tex] is the equation we get.

Step-by-step explanation:

[tex]x^{2} +10x-13=0\\x^{2} +10x+25-13-25=0\\(x+5)^{2}-38=0\\[/tex]

So, we're adding 25-25 to complete the square.

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.

9514 1404 393

Answer:

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

Answer:

x= 15, m<2= 50

Step-by-step explanation:

5x+55 and 2x+100 are equal

5x+55=2x+100

5x=2x+45

3x=45

x=15

Plug it into 5x+55

5(15)+55 = 130

^That angle and <2 are supplementary, so they need to= 180

130+ m= 180

m<2= 50

Answer:

y=-3x+5

Step-by-step explanation: y=mx+b

to find slope (m) use the equation [tex]\frac{y2-y1}{x2-x1} \\[/tex]

so

[tex]\frac{-10-(-1)}{5-2}[/tex] = -3

to find b

use y=mx+b

-1=-3(2)+b

-1=-6+b

5=b
