I need help, I don't understand it

Answer:

2w + 3x ≤ 36

Step-by-step explanation:

Given that :

Hours needed to paint wall = 2 hours

Hours required to frame window = 3 hours

Total hours to spend ≤ 36

Let :

Number of walls to paint = w

Number of windows to frame = x

Hence,

Hours required to paint a wall * number of waas to paint) + (hours required to frame a window * Number of windows to frame.)

(2*w) + (3*x) ≤ 36

2w + 3x ≤ 36

Answer: 119°

Step-by-step explanation:

The two angles are alternate interior angles, meaning they're congruent. If you need help understanding that, just search alternate interior angles. The lines are parallel so it works.

Answer:

no they are not equivalent

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

The ratio would have to be 1:2 or 6:12 or with other factors of the two numbers but the numbers have to be multiplied or divided by the same number to get to those factors in order for them to remain equivalent.

For example: If you were to multiply the 3 by 2 but the 6 by three you'd get 6:18 which simplified is 3:9 not 3:6 but if you multiply both the 3 and the 6 by 3 you'd get 9:18 with can by simplified to 3:6

Answer:

12x-11

Step-by-step explanation:

There is no known solution, but this can be simplified. Add up all of the coefficients(# connected by the variable). Since after 7x is a - , the x following has to be negative. After adding the coefficients, you should have below, 12x. Then, you add up all of your constants.(# w/ no variable). Adding negative and  positive, you should get below, -11. Finally, you should of simplified your equation to 12x-11.

Equation:

7x- (x-4)= 6x -7

7x- (x-4)= 6x -7

12x

7x- (x-4)= 6x -7

-11

12x-11

Step-by-step explanation:

what are you doing with the points then I can help you

Step-by-step explanation:

I don't know if you do this the same way I did, but..

The first step is to subtract 9 on both sides, like this.

13w + 9 = 178

       -9    -9

You'll end up with:

13w = 169

I don't know if you need the answer or not but I'll help you out.

For the second step, divide both sides by 13w.

13w = 169

/13w   /13w

 w = 13

Hope this helped!

Answer:

The first step is that you have to subtract 9 from both sides and you are left with 13w=169 now divide both sides by 13 and you get 13 as your answer.

Answer:

equation of the circle J with center K(-7,3) and radius 6 is=

x^2+y^2+14x-6y+22=0

Step by step explanation:

Equation of circle with given centre (h,k) and radius r is

(x-h)^2+(y-k)^2=r^2

Given centre are K(-7,3) and radius 6.

So equation of Circle=

(x- -7)^2+(y-3)^2=6^2

x^2+14x+49+y^2-6y+9=36

x^2+y^2+14x-6y+22=0 answer

Answer:

(x + 7)² + ( y − 3)² = 36

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is                                (x − h)² + (y − k)² = r².

Define h, k and r using the given values. So, h= −7, k = 3, and r = 6.

Substitute the values into the equation of a circle.

(x − (−7))² + (y −3)²= 62

Simplify.

(x + 7)² + (y − 3)²= 36

Therefore, the equation of the circle J with center K (−7, 3) and radius 6 is (x + 7)² + (y − 3)²= 36.

Answer:

769/70

Step-by-step explanation:

5 2/7 = 37/7

5 7/10 = 57/10

The lowest common multiple is 70

37*10/(7 * 10) = 370/70

57/10 = 57*7/(7*10) = 399/70

Now add

370/70 + 399/70

769/70

Is 769 prime? I think it might be.

Yes it is.

Answer:

[tex]D)\ -1,0[/tex]

Step-by-step explanation:

Given

[tex]4x - 3y= -4[/tex]

Required

Determine which of the options is on the line

The question requires options.

However, I'll answer using the following:

[tex]A) -3, 4[/tex]

[tex]B) -4,3[/tex]

[tex]C)\ 3, 4[/tex]

[tex]D)\ -1,0[/tex]

A point is always of the form (x,y).

So, we have to substitute values for x and y in the given equation

Considering option A:

[tex](x,y)= (-3,4)[/tex]

Substitute [tex]-3\ for\ x\ and\ 4\ for\ y[/tex] in [tex]4x - 3y= -4[/tex]

[tex]4(-3) -3(4) = -4[/tex]

[tex]-12 -12 = -4[/tex]

[tex]-24 \neq -4[/tex]

The above represents an inequality.

Hence, -3,4 does not lie on the equation

Considering option B:

[tex](x,y) = (-4,3)[/tex]

Substitute [tex]-4\ for\ x\ and\ 3\ for\ y[/tex] in [tex]4x - 3y= -4[/tex]

[tex]4(-4) - 3(3) = -4[/tex]

[tex]-16 - 9 = -4[/tex]

[tex]-25 \neq -4[/tex]

The above represents an inequality.

Hence, -4,3 does not lie on the equation

Considering option C:

[tex](x,y) = (3,4)[/tex]

Substitute [tex]3\ for\ x\ and\ 4\ for[/tex] y in [tex]4x - 3y= -4[/tex]

[tex]4(3) - 3(4) = 4[/tex]

[tex]12 - 12 = 4[/tex]

[tex]0 \neq 4[/tex]

The above represents an inequality.

Hence, 3,4 does not lie on the equation

Considering Option D:

[tex](x,y) = (-1,0)[/tex]

Substitute [tex]-1\ for\ x\ and\ 0\ for[/tex] y in [tex]4x - 3y= -4[/tex]

[tex]4(-1) - 3(0) = -4[/tex]

[tex]-4 - 0 = -4[/tex]

[tex]-4 = -4[/tex]

The above represents an equality.

So, -1,0 lies on the equation

Answer:

no

Step-by-step explanation:

3 times -3 is -9. -9 - 5 is -14.

2 times -3 is -6. -6 + 4 is -2.

Answer:

The value of x is -20/3.

Step-by-step explanation:

Answer:

x = - [tex]\frac{20}{3}[/tex]

Step-by-step explanation:

Given

x - 8 = 4x + 12 ( subtract 4x from both sides )

- 3x - 8 = 12 ( add 8 to both sides )

- 3x = 20 ( divide both sides by - 3 )

x = - [tex]\frac{20}{3}[/tex]
