plssss someone help!!!

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:

180 - 55 = angle 1

80 - 55 = 25 so 180 - 55 = 125

angle 1 = 125 degrees

Answer:

p = -1/5

Step-by-step explanation:

-5p + -15/5 = -4

-5p -3 = -4

-5p = -4 +3

-5p = -1

p = -1/5

Answer:

p = [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

Given

- 5 (p + [tex]\frac{3}{5}[/tex] ) = - 4 ← distribute parenthesis on left side by - 5

- 5p - 3 = - 4 ( add 3 to both sides )

- 5p = - 1 ( divide both sides by - 5 )

p = [tex]\frac{1}{5}[/tex]

Answer:

Y= 3

Step-by-step explanation:

1.8/ 0.6=3

Answer:

y=3

Step-by-step explanation:

divide both sides by 0.6

0.6y/0.6 = 1.8/0.6

which sould equal y=3

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.

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:

£9.00

Step-by-step explanation:

67.00-49.00 = 18.00÷2 = 9.00

Let's Try:

a) 9.00×7 = 63.00+4.00(hat) = 67.00

b) 9.00×5 = 45.00+4.00(hat) = 49.00

Answer:

tshirt equals £9

and hat equals £4

Step-by-step explanation:

7t + h = 67

5t +h  = 49      subtract bottom eq from top

2t = 18      t = 9

5(t) + h = 49

5(9) + h = 49

45 + h = 49

h = 4

39

Step-by-step explanation:

x² + 14 ← substitute x = - 5

= (- 5)² + 14

= 25 + 14

= 39

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
