The answer would be 80 because you are multiplying each number by 2. You multiply 5 x 2 = 10, 10 x 2 = 20, 20 x 2 = 40, and then 40 x 2 = 80. That is how I got the answer 80!!

A line passes through the points (6,5) and (2,2) . Select Yes or No to tell whether each equation describes this line. Equation

Marta_Voda [28]

ANSWER

$y-5=\frac{3}{4}(x-6)$ ,Yes

$y-5=-\frac{4}{3} (x-2)$ ,NO

$y-2=-\frac{3}{4} (x-6)$ ,NO

$y-2=\frac{3}{4}(x-2)$ ,Yes

EXPLANATION

The line passes through these two points, $(6,5)$ and $(2,2)$ .

We can use these two points to determine the slope of the line.

The formula for finding the slope of a line when at least two points are known is $m=\frac{y_2-y_1}{x_2-x_1}$ .

We can choose $(x_1,y_1)=(6,5)$ and $(x_2,y_2)=(2,2)$ or $(x_1,y_1)=(2,2)$ and $(x_2,y_2)=(6,5)$ .

We shall get the same result.

$m=\frac{2-5}{2-6} =\frac{-3}{-4} =\frac{3}{4}$ .

We now determine the equation of the line using the poit-slope formula,

$y-y_1=m(x-x_1)$ .

When we choose $(x_1,y_1)=(6,5)$ , then we will obtain,

$y-5=\frac{3}{4}(x-6)$ as the point-slope form.

When we choose $(x_1,y_1)=(2,2)$ , then we will obtain,

$y-2=\frac{3}{4}(x-2)$ as the point-slope form.

PLEASE HELP ME ASAP! I need to know the 3 equations to solve for the different types of points.

kiruha [24]

Answer:

f = 0

x > 2y

x ≤ 8

S ≥ 18

Step-by-step explanation:

Let 'f' represent the number of free throws.

Let 'x' represent the number of 2 - point baskets.

Let 'y' represent the number of 3 - point baskets.

Let S represent the Season high.

1) Ryan says he did not shoot any free throws.

⇒ f = 0

2) 2 - point baskets more than twice the number of 3 - point baskets.

⇒ x > 2y

3) Number of two points is less than or equal to 8.

⇒ x ≤ 8.

4) Last Season high, he had scored 18 points. Note that the problem says, Ryan equaled or bettered than last season high. That means he should got at least 18 points this season. So, the equation would be:

S ≥ 18

<h2><u>Answer:</u></h2>

'?' is <u>88°.</u>

<h2><u>Step-by-step explanation:</u></h2>

First, we work out the final angle of the left triangle, which has a total of 180°. To do this we take 40° and 66° from 180°, giving us <u>72°</u>
Because there is a straight line along the bottom (which will total 180°), we take both 72° and 56° from 180°, giving us <u>52°</u>, which is the bottom left angle of the right triangle.
Finally, to work out '?', we take 52° and 40° from 180° to get our final answer of <u>88°.</u>
