Write the equation of a line that passes through the points in the table.

x (-1, -4, -7)
y (5, 11, 17

Answers

Answer:

y = -2x + 3

Step-by-step explanation:

Lets just put the three points together.

(-1, 5) (-4, 11) (-7, 17)

First let's find the slope with y2 - y1/x2 - x1

Plug in using (-1, 5) and (-4, 11)

11 - 5/-4 + 1 = 6/-3 (simplify)

-2 is the slope

Now plug in (-7, 17) in the equation to get b or the y-intercept)

y = mx + b

17 = -2(-7) + b

17 = 14 + b (subtract 14 on both sides)

3 = b

y = -2x + 3

The equation of the line that passes through the points in the table is:[tex]y = -2x +3[/tex]

The line passes through the following points

x (-1, -4, -7)

y (5, 11, 17)

Start by calculating the slope (m) of the line

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{17 - 11}{-4+1}[/tex]

Evaluate the differences

[tex]m = \frac{6}{-3}[/tex]

Evaluate the quotient

[tex]m = -2[/tex]

The equation is then calculated as:

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

This gives

[tex]y = -2(x+1) +5[/tex]

Open the brackets

[tex]y = -2x-2 +5[/tex]

Evaluate the like terms

[tex]y = -2x +3[/tex]

Hence, the equation of the line is:[tex]y = -2x +3[/tex]

The completed formula is ___c____3=____
There are___items. He will choose____

Answers

Answer:

It would be a 3/4 chance that he will pull the right 4 coins.

Step-by-step explanation:

The probability that the first 3 coins are equal to $0.40 will be 1/4

How to explain the probabaility?Q=event of pulling a quarter (25 cents)D=event of pulling a dime (10 cents)N=event of pulling a nickel (5 cents)P=event of pulling a penny (1 cent)

Simon needs to pull out the penny last so that the first three coins add up to $0.40. We assume the coins are wrapped so it is a random choice.

For the first coin, the probability of not pulling a penny is 3/4, similarly, for the second coin, the probability of not pulling a penny is 2/3,

For the third coin, the probability of not pulling a penny is 1/2,

P(3 coins but no penny) = (3/4*2/3*1/2) = 1/4

Hope this helps and I'd appreciate a brainliest.

Answer: The kicker must have attempted 44 field goals.

Step-by-step explanation:

If the kicker missed 2 out of every eleven field goals, then this is a division and multiplication problem.

8 ÷ 2 lets us know what number to multiply 11 by, which in this case, is 4.

4 x 11 = 44, and in the context of the question, this would mean that the kicker attempted 44 total field goals.

Answers

Answer:

x = 4

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, subtract 4 from both sides of the equation:

-6x + 4 (-4) = -20 (-4)

-6x = -20 - 4

-6x = -24

Next, divide -6 from both sides of the equation:

(-6x)/-6 = (-24)/-6

x = (-24)/(-6)

x = 4

Step-by-step explanation:

let y = g(x) and rearrange making x the subject, that is

y + 11 = 4x ( divide both sides by 4 )

[tex]\frac{y+11}{4}[/tex] = x
