PLZ HELP!!!! A pair of equations is shown below: y = 6x − 4 y = 5x − 3 Part A: In your own words, explain how you can solve the
Goryan [66]

Answer:

Step-by-step explanation:

y = 6x − 4

y = 5x − 3

A: chose a value for x(input) and get the out put (y) because the equation already in the slope intercept mode:y=mx+b

x                   y=6x-4                  y=5x-3

1                    y=2                        y=2

2                    y=8                        y=7

0                     -4                            -3

slope  :

y=6x-4    slope is 6            y intercept(0,-4)

y=5x-3      slope is 5          y intercept (0,-3)

solution of the pair of equation is  the point of intersection :

6x-4=5x-3

6x-5x=-3+4

x=1   and y=6x-4   ⇒ y=6-4=2

Calculate the area of the regular pentagon below:
jarptica [38.1K]

Answer: 238.95 in²

because this is a regular pentagon

=> the area of the regular pentagon will be 5 times the area of the triangle in the picture.

we have: the area of the triangle is: (11,8.8,1)/2 = 47,79 (in²)

=> the area of the regular pentagon is 5. 47,79 = 238,95 (in²)

Yoooo help
stich3 [128]

Answer:

0 - 1 - 2 - 3 - 4 - 5

2 - 22.1 - 32.4 - 32.9 - 23.6 - 4.5

Step-by-step explanation:

<u>The function is:</u>

  • H(t) = -4.9t^2 +25t +2

<u>Calculating the value of H for each value of t from 0 to 5</u>

  • H(0) = 2
  • H(1) = -4.9*1^2 + 25*1 + 2 = 22.1
  • H(2) = - 4.9*2^2 + 25*2 + 2 = 32.4
  • H(3) = -4.9*3^2 + 25*3 + 2 = 32.9
  • h(4) = -4.9*4^2 + 25*4 + 2 = 23.6
  • H(5) = - 4.9*5^2 + 25*5 + 2 = 4.5

Correct answer choice is the 3rd one or C
