the rectangle below has a perimeter of 120 in right an equation to solve for x and then calculate the length and width of the rectangle.​

Answer:

AOE = 138, EOD = 48

Step-by-step explanation:

Since AD is the diameter of the circle and goes through the middle

angle AOE + angle EOD  = 180

Solving the equation (x + 138) + ( x+ 48) = 180

We get x = 0.

Answer:

y + 5 = -3(x - 0)

Step-by-step explanation:

First, you find the slope. To do that, you subtract the second y point (in this case 4) by the first y point (in this case -5), and you get 9. Then, you subtract the second x point (in this case -3) by the first x point (in this case 0), and you get -3. Y is over X, so you get 9/-3 or 9 over -3, which can simplify to -3.

Next, you use the point slope formula: y - y1 = m(x - x1). Add in the y1, m, and x1, then solve if it asks you to put it in slope intercept form. So, for this case, it would be y + 5 = -3(x - 0)

Yay!!!! :D

Answer:

~20.6155

Step-by-step explanation:

To compute distance between two points, we can get the vector from one to the other by subtracting them and then computing the length of the vector.

The length of a vector V is:

[tex]|V| = \sqrt{\sum_{i=1}^n v_i^2}\\[/tex]

The vector is:

(9, -5. 4) - (-10, 3, 4) = (9 + 10, -5 - 3, 4 - 4) = (19, -8, 0)

So the length is:

[tex]\sqrt{19^2 + (-8)^2} = \sqrt{361 + 64} = \sqrt{425} = \sqrt{5\cdot 5\cdot 17} = 5\sqrt{17} \approx 20.6155281281[/tex]

Answer:

A

Step-by-step explanation:

The equation of a vertical line parallel to the y- axis is

x = c

where c is the value of the x- coordinates the line passes through.

The line passes through (4, 5 ) with x- coordinate 4 , then

x = 4 ← equation of vertical line → A

Answer:

Infinite number of solutions.

Step-by-step explanation:

Y=5x+1

-5x+Y=1

substitute value of y in first equation (5x+1) into 2nd equation

-5x+5x+1=1

0+1=1

1=1

since answer equals on both sides of the equatio, the answer is determined to be infinite.

Answer:

x = 108 because of supplementary angles

Step-by-step explanation:

Solving for x:

Since x and 72 are supplemenatry angles, they'll equal to 180, so:

x + 72 = 180

x = 180 - 72

x = 108

Absolute value is the distance from zero, it doesnt matter if its -58 or 58 its absolute value is always going to be positive, so if you have a negative just get rid of that negative sign. Absolute value makes it all positive -492= 492 in absolute value.

40=5×8

Step-by-step explanation:

I think, hope this helps

The equation for the number 40 is 5 times as many as 8 is; 40=5×8

An equation represents equality of two or more mathematical expression.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

Solutions to an equation are those values of the variables involved in that equation for which the equation is true.

We are given that the number 40 is 5 times as many as 8

40 is 5 times as many as 8 means

5×8 = 40

Then the equation will be;

40=5×8

Answer:

50%

Step-by-step explanation:

We need to find the percent change from 120 pounds to 180 pounds. We can find it as follows :

[tex]\%=\dfrac{180-120}{120}\times 100\\\\=\dfrac{60}{120}\times 100\\\\=50\%[/tex]

So, the percent change is equal to 50%.

f ( 2 ) = 2 × f ( 2 - 1 ) + 1

f ( 2 ) = 2 × f ( 1 ) + 1

f ( 2 ) = 2 × ( - 3 ) + 1

f ( 2 ) = - 6 + 1

f ( 2 ) = - 5

Step-by-step explanation:

Coincidentally, you answered correctly.

From the values of 3 and five, we can assume that the function of the table is Y=x+2.

But if we move to the next value pairs, that function is false.

10=6+2 that isn't correct.

If you apply this to all the pairs in the table you will find that there is not a function that represents the values given. Therefore, the first option is correct.

Answer:

Answer is -7x - 10

Step-by-step explanation:

First you would want to subtract the numbers here it is

4x -7 + 8x -3 - 19x

4x - 10 + 8x - 19x

Then you would want to combine the terms

and the answer is  

17x - 10

Answer:

It's hard to make out which is x and y, if x is lower right and y is at the top, then:

x = 55°

y = 70°

Step-by-step explanation:

x = 55° because it is an isosceles triangle

y = 180° - 55° - 55° = 70°

21/30 = 7/10 = 0.7

Step-by-step explanation:

spliting up 21 dollars among 30 winners, is dividing 21 by 30. When you do this you can simplify it to 21/30 = 7/10. 7/10 is equal to 0.7.

Answer:

$0.7

Step-by-step explanation:

As you may know, instead of saying divide. You can say split. So $21 split between 30 people would be $0.7 or 70 cents.
