Help Me Please I Will Mark Brainliest If Correct

Answers

Answer 1

Answer:

-11

8 = 2x + 30

8 - 30 = -22

-22 ÷ 2 = -11

x = -11

Also if you place 2×(-11) + 30 you get 8

To the nearest tenth, what is the perimeter of the triangle with vertices at (−2, 3), (3, 6), and (2, −2)?

Answers

9514 1404 393

Answer:

  20.3

Step-by-step explanation:

The distance formula can be used to find the side lengths.

  d = √((x2 -x1)^2 +(y2 -y1)^2)

For the first two points, ...

  d = √((3 -(-2))^2 +(6 -3)^2) = √(5^2 +3^2) = √34 ≈ 5.83

For the next two points, ...

  d = √((2 -3)^2 +(-2-6)^2) = √(1 +64) = √65 ≈ 8.06

For the last and first points, ...

  d = √((-2-2)^2 +(3-(-2)^2) = √(16 +25) = √41 ≈ 6.40

Then the sum of the side lengths is ...

  5.83 +8.06 +6.40 = 20.29 ≈ 20.3

The perimeter of the triangle is about 20.3 units.

the lager value of y for which (y-1)²=4y-7 is​

Answers

Answer:

the lager value of y is 4.

Step-by-step explanation:

Given;

(y-1)² = 4y - 7

Simplify as follows;

(y - 1)(y - 1) =  4y - 7

y² - y - y + 1 =  4y - 7

y² - 2y  +  1  =  4y - 7

Collect like terms

y² -2y - 4y + 1 + 7 = 0

y² - 6y + 8 = 0

Factorize the equation;

y² -2y - 4y + 8 = 0

y(y - 2) -4(y - 2) = 0

(y - 2)(y - 4) = 0

y = 2   or   y = 4

Thus, the lager value of y is 4.

Write an equation in point-slope form for the line that passes through the point with the given slope.

Answers

Answer:

Slope: 3

Equation: y + 2 = 3(x + 1)

Step-by-step explanation:

Find the slope using (-1, -2) and (0, 1):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - (-2)}{0 - (-1)} = \frac{3}{1} = 3 [/tex]

Slope (m) = 3

The equation can be represented in point-slope form, y - b = m(x - a)

Where,

(-1, -2) = (a, b)

m = 3

Plug in the values into y - b = m(x - a)

y - (-2) = 3(x - (-1))

y + 2 = 3(x + 1)

Step-by-step explanation:

From the question, we were told that a basket ball team six games and in those games, the team won by 8 points, lost by 7, won 9 , won 11 , lost by 3 and won by 6

The mean difference in games scored over the six games would be calculated as the addition of the scores divided by 6

= [8 + (-7) + 9 + 11 + (-3) + 6] / 6

= 24 / 6

There are 1.75 hours he gets overtime for. So multiply 1.75(11.50)(1.5). You’ll get $30.19. That’s his overtone pay so add it to the 460.

Answers

Answer:

y = 4x + 11

Step-by-step explanation:

From the question given above, the following data were obtained:

Coordinate = (–2, 3)

Slope (m) = 4

We can express the above in slope intercept form as follow:

Slope (m) = 4

x–coordinate (x₁) = –2

y–coordinate (y₁) = 3

y – y₁ = m(x – x₁)

y – 3 = 4(x – –2)

y – 3 = 4(x + 2)

y – 3 = 4x + 8

Make y the subject of the expression by rearranging

y = 4x + 8 + 3

y = 4x + 11

Therefore, the slope intercept form is

y = 4x + 11

in an academic contest, correct answers earn 12 points and incorrect answers lose 5 points. In the final round, School A starts with 165 points and given the same number of correct and incorrect answers. School B starts with 65 points and given no incorrect answers and the same number of correct answers as School A. The game ends with the Schools tied.

Part A: Which equation models the scoring in the final round and the outcome of the contest?
A.) 12x + 5x - 165 = -12x + 65
B.) 12x - 5x + 165 = 12x + 65
C.) 5x - 12x + 165 = 12x + 65
D.) 12x - 5x - 165 = 12x +65

Part B: How many answers did each school get correct in the final round?

Answers

Answer:

part a is b part b is 230 tell me if im wrong

Step-by-step explanation:

Step-by-step explanation:

Let x represent the number of correct answers School A gave.

Then x is also the number of incorrect answers School A gave and the number of correct answers School B gave.

Final score of School A

= 165 + 12x - 5x.

Final score of School B

= 65 + 12x

Hence the correct equation is

12x - 5x + 165 = 12x + 65. (B)

=> 7x + 165 = 12x + 65

=> 5x = 100

=> x = 20

Hence Schools A and B got 20 correct answers each.

Linear:

Step-by-step explanation:

Linear equations are generally expressed in the form y = mx + b - the highest exponent of x is one.

Quadratics are expressed as y = ax^2 + bx + c - the highest exponent of x is two.

Any equation with an exponent of x higher than two is neither linear nor quadratic, but instead cubic or higher.  Therefore we can simply sort these equations by the highest exponent of x present after simplifying.
