Answer:

38

Step-by-step explanation:

Answer:

62

Step-by-step explanation:

so because the triangle going through the center it classifieds as a right triangle which makes angle SRT = 90 degree

three angle of a triangle add up to 180

so we have SRT + RTS + RST = 180

we have SRT

=> 90 + RTS + RST = 180

=> 90 + (3x -25) + (x - 1 ) = 180

=> 90 + 4x -26 = 180

=> 64 + 4x = 180

=> 4x = 116

=> x = 29

now u have x , just plug in and solve

Answer:

x2+14 x=-5

-5(2)+14

-10+14=4

Answer:

39

Step-by-step explanation:

x² + 14 ← substitute x = - 5

= (- 5)² + 14

= 25 + 14

= 39

Answer:

The answer is C

Step-by-step explanation:

Well I took a lesson on volume before and volume and In math, volume can be defined as the 3-dimensional space enclosed by a boundary or occupied by an object. Here, the blocks and books take up space.

The correct definition of volume is,

⇒ The amount of space a 3-dimensional object takes up.

Option C is true.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

To find the definition of volume.

We know that;

Volume is known as the space occupied within the boundaries of an object in 3D- space. It is also known as the capacity of the object.

Thus, The correct definition of volume is,

⇒ The amount of space a 3-dimensional object takes up.

Option C is true.

9514 1404 393

Explanation:

To find the time, substitute the height for h(t), then solve the quadratic equation for t.

___

To solve the equation, you subtract the height from both sides, then use the quadratic formula. In generic terms, this looks like ...

  -16t^2 +32t -h = 0

  t = (-32±√(32^2 -4(-16)(-h)))/(2(-16))

  t = (-32 ± √(1024-64h))/-32

  t = 1 ± √(1 -h/16)

For h = 10 ft, the times are ...

  t = 1 ± √(3/8) ≈ {0.388, 1.612} . . . . seconds

__

Using the quadratic formula is not the only way to solve a quadratic. One of my favorite methods is using a graphing calculator.

Answer:

The answer is 8

Step-by-step explanation:

I just took the test

The greatest common factor of 8x and 40y is: 8.

Greatest common factor (HCF) is the largest positive integer that can divide a set of whole numbers evenly. In order words, all the numbers in a set share the same factor, which is the HCF.

Given:

8x and 40y

Both share a factor of 8.

Therefore, the greatest common factor of 8x and 40y is: 8.

Answer:

y=2.5x+3

Step-by-step explanation:

(0,3) shows the y-intercept of +3

Use slope formula to find the slope:

8-5.5/2-1 = 2.5

therefore the M (slope) is 2.5

Answer:

y = 2.5x + 3

Step-by-step explanation:

y2 - y1/x2 - x1 = slope

5.5 - 3 = 2.5

2 - 1 = 1

2.5/1 = 2.5

8 = 2.5(2) +b

8 = 5 + b = 3

Answer: 35p+65

Answer:B is the answer

Answer:

B. (-2,1)

Step-by-step explanation:

Coincidently, I was doing my System of Equations: Word Problems HW when i saw this.

So, I'll solve using Elimination.

Convert equations into standard form: -3x + y = 7 and 2x + y = -3

Multiply first equation by -1 and arrange vertically.

2x + y = -3

3x - y = -7

-----------------    <Now, Add!>

5x = -10

Divide by 5 on both sides

5x/5 = -10/5

x=-2

Plug x=-2 into any equation.

y=3(-2) + 7

y= -6 + 7

y=1

So the Point of Intersection, or solution, is (-2,1)
