Answer:

Step-by-step explanation:

5m - 2n = 4

 m - 4n = -1     add 4n to both sides   m - 4n + 4n = 4n - 1  

 m = 4n - 1      now substitute for m into the first equation

5(4n -1) - 2n = 4

20n - 5 - 2n = 4           combine the n coeffients  and add 5 to both sides

18n - 5  = 4 + 5

18n  = 9      solve for n      by dividing 18 by both sides

 18 n/18   =  9 /18

      n   =    1/2      now find for m using  m = 4n - 1    m = 4(1/2) - 1   m = 2 -1  = 1

      m  =   1          (1, 1/2)  solves the two equations

3x + 5y = 11      equation 1    

2x - y = 3​          multiply both sides by 5 so when you add the two equation

                         the y term is eliminated  (becomes zero)

5(2x-y) = 5(3)

10x - 5y = 15    equation 2      add equation 1 and equation 2

3x + 5y = 11     add the like terms

10x - 5y = 15    add the like terms

(3x + 10x) + (5y - 5y) = (11 + 15)

   13x        +     0       =    26               the y tern is gone   now solve for x      

   13x = 26

    13x/13  = 26/13

     x = 2                        now find y    using  2x - y = 3

   2x - y = 3         add y and subtract 3 from both sides

   2x - y + (y - 3)  =  3 + (y - 3)

   2x - 3 = y         we already know x = 2

   2(2) - 3 = y

     4 - 3 = y

        1  = y           answer (2,1)   solves the two equaitons

Answer:

1. Turbine

2. Generator

3. Power line

No, the US and other countries shouldn't use more wind energy because the turbine could cause harm to animals that fly.

OR you can say:

Yes, the US and other countries should use more wind energy because it doesn't cause pollution, so no greenhouse gases are made to contribute to global warming.

Answer:

D. -1/8

Step-by-step explanation:

I am sorry but I can not help you with this because there are no angles

Answer:

a. The slope is [tex]\frac{-1}{3}[/tex] and the y-intercept is 0

b. The slope is [tex]\frac{2}{3}[/tex] and the y-intercept is [tex]-\frac{5}{3}[/tex]

c. The slope is [tex]\frac{-1}{2}[/tex] and the y-intercept is 2

Step-by-step explanation:

The easiest way to find the slope and y-intercept is to put each equation in the slope-intercept form

That is:

y = mx = c

where m is the slope and c is the y-intercept

Part a:

6(x+y) = 3(x-y)

2(x+y) = x-y

2x + 2y = x - y

3y = -x

[tex]y = \frac{-1}{3}x[/tex]

Comparing this with the general formula, we can conclude that:

The slope is [tex]\frac{-1}{3}[/tex] and the y-intercept is 0

Part b:

2(x+y) = 5(y+1)

2x + 2y = 5y + 5

3y = 2x - 5

[tex]y = \frac{2}{3}x - \frac{5}{3}[/tex]

Comparing this with general formula, we can conclude that:

The slope is [tex]\frac{2}{3}[/tex] and the y-intercept is [tex]-\frac{5}{3}[/tex]

Part c:

5x + 10y -20 = 0

10y = -5x + 20

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

Comparing this with the general formula, we can conclude that:

The slope is [tex]\frac{-1}{2}[/tex] and the y-intercept is 2

Answer:

54.94 inches

Step-by-step explanation:

First you need to find the radius of the semi-circles within the square.

You find this by dividing the perimeter by 8

64/8 = 8

now use the formula πr^2 to find the area of the semi circle

π8^2 = 201.06

Now find the total area of the square and subtract it from the area of the two semi circles to find the shaded region

16*16 = 256

256-201.06 = 54.94

Answer:

3. B

4. D

Step-by-step explanation:

3. The y-intercept is -4 and the slope is positive 2.

4.Substitute the values and check

Answer and Step-by-step explanation:

3.

Before we look at the answer choices, lets analyze the graph.

We see that as the graph goes right, the y values are positive, and that as the graph goes left, the y values become negative/decrease. (Graph, as in the line on the graph).

That means the graph has a positive slope. So we can get rid of any negative slopes (answer choices A and C).

Now, we look to see the rate of change of the graph. How many units does the graph go up and right right?

We see that the graph has a rate of change of 2, so that is the slope.

This means that answer choice B is the answer. The equation shows that it goes down 4 units as well, which is what the graph shows as well.

4.

For this one, we need to see the pattern in the table.

When we put 2 in for n, we get 6. When we put 3 in for n, we get 8. And when we put 4 in for n, we get 10.

Answer choice D works for this. If we plug 2, 3, and 4 in for this expression, we get:

2(2) + 2 = 4 + 2 = 6

2(3) + 2 = 6 + 2 = 8

2(4) + 2 = 8 + 2 = 10

So answer choice D is the answer.

Answer:

x=7/3 or x=2.33

Step-by-step explanation:

9x^2 - 52x + 33 = -10x - 16

Okay, lets Start by converting this into standard form, which is: ax^2 + bx + c = 0.

Add 10x+16 on both sides of the equation, and simplifying.

9x^2 - 52x + 33 + 10x + 16  = -10x - 16 + 10x + 16

9x^2 - 42x + 49 = 0

Guess What! This equation is a Perfect Square Trinomial.

For a Perfect Square Trinomial, you will be able to take the square root of the first  and third terms, and the coefficient of the second term will be twice the square root of the  third term. The “sign” of your second term in your answer will be the same as the linear term sign.

So this is (3x*3x) + (3x * -7 * 2) + (7 * 7) = 0

So, we can rewrite this as (3x - 7)^2=0

Now, To solve, We can set each factor equal to 0, and solve.

*Since we have a Perfect Square Trinomial, You will get one solution, or value, for x.*

Add 7 on both sides.

3x - 7 = 0

     +7  +7

----------------

3x=7

Divide by 3 on both sides.

3x/3 = 7/3

x=7/3

As a decimal: 2.33...

Answer:

2,820 m

Step-by-step explanation:

Given that the rectangular piece of land measures 250m by 220 m, the perimeter of the rectangle gives the length of wire required to fence it once.

The perimeter p of a rectangle of length l and width b is given as

p = 2(l + b)

Hence p = 2( 250 + 220)

= 2 * 470

= 940 m

Since each side is to be fenced with 3 rows of wires, the length of wire required

= 3 * 940m

= 2,820 m

Given:

In an office, there are 75 women and 125 men.

To find:

The ratio of the number of men to the number of women.

Solution:

We have,

Number of men = 125

Number of women = 75

The ratio of the number of men to the number of women is:

[tex]\text{Required Ratio}=\dfrac{\text{Number of men}}{\text{Number of women}}[/tex]

[tex]\text{Required Ratio}=\dfrac{125}{75}[/tex]

[tex]\text{Required Ratio}=\dfrac{5}{3}[/tex]

[tex]\text{Required Ratio}=5:3[/tex]

Therefore, the ratio of the number of men to the number of women is 5:3.

Answer:

I think the answer will be Y=X+7

Answer:

y=x+7

Step-by-step explanation:

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

m=(7-2)/(0-(-5))

m=5/(0+5)

m=5/5

m=1

y-y1=m(x-x1)

y-2=1(x-(-5))

y-2=x+5

y=x+5+2

y=x+7
