Answer:

  no

Step-by-step explanation:

A proportion is an equation saying two ratios are equal to each other.

One ratio is not a proportion.

___

It would be a proportion if it were said to equal something:

  2/7 = peanuts/popcorn . . . is a proportional expression

Answer:38.41%

explanation:........

Answer:

The answer is x=4 or x=−10

Solutions:

(x + 3)² = 49

(x+3)(x+3)=49

x²+6x+9=49

x²+6x+9-49=0

(x-4)(x+10)

x-4=0 x+10=0

x=4 x=-10

Answer:

y = 2x - 7

Step-by-step explanation:

The question is asking for slope-intercept form, y = mx + a.

Given:

(1, -5) and (9, 11)

Find the slope (m) between the two points:

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

x1 = 1

x2 = 9

y1 = -5

y2 = 11

m = ( 11 - (-5) )/(9 - 1)

= 16/8

m = 2

y = 2x + a

Use one of the two points to find a (I will use (1, -5)):

-5 = 2(1) + a

-5 = 2 + a

-7 = a

a = -7

y = 2x + (-7)

y = 2x - 7

Answer:

(6, 1)

Step-by-step explanation:

We are given the equation for (y), [y=x-5]

So we can implement that in all the places the (y) are in the other equation.

x+3(x-5)=9

x+3x-15=9

add 15 to each side

4x=24

Divide each side by 4

x=6

Now we can apply our (x) into one of the equations.

y=(6)-5

y=1

So our solution is (6, 1)

Step-by-step explanation:

Answer:

the answer would be 211

Step-by-step explanation:

you simply add the length and width together to find perimeter. since you have the total perimeter and the length you would instead subtract the two.

292-81= 211

Answer:

68m

Step-by-step explanation:

The perimeter  of a rectangle with length  and width  is given by the following.

P=21+2w

We need to find w when P=292 m  and l+78m .

Using these values in the equation above, we'll solve for w.

P=21+2w

292=2(78)+2w

292=156+2w

136=2w

68=w

Subtracting 156  from both sides

Dividing both sides by  2

So the width of the parking lot is 68m

Answer:

the correct answer would be p=nRt/v

Step-by-step explanation:

you would devide both sides by v to get the new equation

Answer:

        [tex]y=\frac{1}{2}x+5[/tex]

Step-by-step explanation:

Considering the line graph

Some of the points on the line are given by

Finding the slop between any two given points

Let us take the point (0, 5) and (2, 6)

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0,\:5\right),\:\left(x_2,\:y_2\right)=\left(2,\:6\right)[/tex]

[tex]m=\frac{6-5}{2-0}[/tex]

To the  y-intercept, set x = 0.

We already know that when x = 0, the value of y = 5

so

Equation of line can be obtained using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = 1/2 and any point let say (2, 6)

[tex]y-6=\frac{1}{2}\left(x-2\right)[/tex]

add 6 to both sides

[tex]y-6+6=\frac{1}{2}\left(x-2\right)+6[/tex]

[tex]y=\frac{1}{2}x+5[/tex]

Therefore, the equation of the line is:

Answer:

10 pencils

Step-by-step explanation:

Given that:

Number of pencils bought by Sam and Sara are the same.

Let the number of pencils bought = x

Sam put 1/4 in his pencil box

Sara put 1/2 in her pencil box

1/4 of Sam's pencil = 5

That is ;

1/4 of x = 5

x /4 = 5

x = 20

Hence, number of pencils Sara put in her box

:

1/2 of 20

1/2 * 20

20/2

= 10

10 pencils

Answer:

5.83

Step-by-step explanation:

i used pythagorean theorem

side a is 5 because congruence

side b would be 3 because 9 - 6 = 3

5^2 + 3^2 = c^2

25 + 9 = c^2

34 = c^2

sqrt of 34 is 5.83

Question:

The area, a, of an ellipse can be determined using the formula a = πxy, where x and y are half the lengths of the largest and smallest diameters of the ellipse. Which is an equivalent equation solved for y?

Answer:

[tex]y = \frac{a}{\pi x}[/tex]

Step-by-step explanation:

Given

[tex]a = \pi xy[/tex]

Required

Solve for y

The question implies that, we make y the subject of formula:

This is done as follows:

[tex]a = \pi xy[/tex]

Divide through by [tex]\pi x[/tex]

[tex]\frac{a}{\pi x} = \frac{\pi xy}{\pi x}[/tex]

Isolate y on the right hand side

[tex]\frac{a}{\pi x} = y[/tex]

Reorder

[tex]y = \frac{a}{\pi x}[/tex]

Hence, the solution to the question is: [tex]y = \frac{a}{\pi x}[/tex]
