9t-(2t-4)=25 I’m not sure how to use the distributive property to solve for t

Answer:

y = (-2/3)x + 4 or

3y = -2x + 12

Step-by-step explanation:

Slope of line passing through (x₁, y₁) and (x₂, y₂) is given by
[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

In this particular case where the points are (6,0) and (0,4) we get the slope as (4-0)/(0-6) = -2/3

Equation of a line with slope m and y intercept c is given by

y = mx + c

substituting for m we get the equation y = (-2/3)x + c

Substituting the first point (6,0) we get

0 = (-2/3)(6) + c or -4 + c = 0 or c =4

Therefore y = (-2/3)x + 4 or multiplying both sides by 3 we get

3y = -2x + 12

Answer:

A) 30x

Step-by-step explanation:

5(x - 2x + 6x + 10)

Distribute:

5(x) + 5(-2x) + 5(6x) + 5(10)

5x - 10x + 30x + 50

Therefore, 5(x - 2x + 6x + 10) is equivalent to 5x - 10x + 30x + 50

Hope this helps!

Answer:

A) 30x

Step-by-step explanation:

Given equation:

5(x – 2x + 6x + 10) = 5x – 10x + ? + 50

Let the "?" be represented as "a". Then,

⇒ 5(x – 2x + 6x + 10) = 5x – 10x + a + 50

[Right hand side] Put all the terms inside a parenthesis (except "a").

⇒ 5(x – 2x + 6x + 10) = 5x – 10x + a + 50

⇒ 5(x – 2x + 6x + 10) = (5x – 10x + 50) + a

Isolate the "a" on one side by subtracting the terms inside the parenthesis.

⇒ 5(x – 2x + 6x + 10) - (5x – 10x + 50) = (5x – 10x + 50) + a - (5x – 10x + 50)

⇒ 5(x – 2x + 6x + 10) - 5x + 10x - 50 = a

[Left hand side] Simplify the distributive property

⇒ 5(x – 2x + 6x + 10) - 5x + 10x - 50 = a

⇒ (5x – 10x + 30x + 50) - 5x + 10x - 50 = a

[Left hand side] Open the parentheses

⇒ (5x – 10x + 30x + 50) - 5x + 10x - 50 = a

⇒ 5x – 10x + 30x + 50 - 5x + 10x - 50 = a

[Left hand side] Combine like terms and simplify

⇒ 5x – 10x + 30x + 50 - 5x + 10x - 50 = a

⇒ x(5 – 10 + 30 - 5 + 10) + (50 - 50) = a

⇒ x(30) = a

[Left hand side] Open the parenthesis and simplify

⇒ x(30) = a

⇒ 30x = a = ?

Therefore, the correct option is A (30x).

Answer:

I only did 1-16 but here:

11. x² + y² = 4

12. (x+3)² + (y-3)² = 1

13. x² + (y-3)² = 16

14. (x-7)² + (y+2)² = 4

15. x² + (y+20)² = 100

16. (x+4)² + (y+6)² = 16

Step-by-step explanation:

If 5x - 8 = 12 , then x = 4

5x - 8 = 12

5x = 12 + 8

5x = 20

x = 20/5

x = 4

If -2(3x + 5) = -17 + x , then x = 1

-2(3x + 5) = -17 + x

-6x - 10 = -17 + x

x + 6x = 17 - 10

7x = 7

x = 7/7

x = 1

Answer:

B and D because I know that I think

Answer:

1) y = 1.5x + 1

2) y = x + 4

Explanation:

[tex]\sf slope : \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]\sf slope = \dfrac{4-1}{2-0} =1.5[/tex]

Equation:

[tex]\sf y - y_1 = m(x-x_1)[/tex]

[tex]\sf \rightarrow y - 1 = 1.5(x - 0)[/tex]

[tex]\sf \rightarrow y = 1.5x + 1[/tex]

[tex]\sf slope = \dfrac{4-1}{0-(-3)} =1[/tex]

Equation:

[tex]\sf y - y_1 = m(x-x_1)[/tex]

[tex]\rigtharrow \sf y - 4 = 1(x-0)[/tex]

[tex]\rigtharrow \sf y = x + 4[/tex]

Step-by-step explanation:

The first line on the box plot is always the minimum value

Using the normal distribution, it is found that he needs a score of 605 in exam b in order to do equivalently well as he did on exam a.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

For the z-score for exam a, we have that the parameters are given as follows:

[tex]X = 22, \mu = 40, \sigma = 10[/tex]

Hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{22 - 40}{10}[/tex]

Z = -1.8.

Then, for the equivalent grade X in exam B, we have that:

[tex]Z = -1.8, \mu = 650, \sigma = 25[/tex]

Then:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1.8 = \frac{X - 650}{25}[/tex]

X - 650 = -1.8 x 25

X = 605.

The P(pass | Test A) is 31.81%, P(pass | Test B) is 29.87%

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Part A:

Total number of students = 154

Total number of students passed the test = 49

The probability:

P(pass | Test A) = 49/154 = 31.81%

Part B:

Total number of students = 154

Total number of students passed the test = 46

The probability:

P(pass | Test B) = 46/154 = 29.87%

Thus, the P(pass | Test A) is 31.81%, P(pass | Test B) is 29.87%.
