when looking at an equation, how do you know if it has direct variation​?

Answers

Answer 1
Answer: A direct variation is when x and y (or f(x) and x) are directly proportional to each other... For example, if you have a chart that says x and y, and in the x column is 1, 2 and 3, and the y column says 2, 4 and 6... then you know it's proportional because for each x, y increases by 2.

Hope this helps (:

Hi, You are the person I answered last time!

P(event) = 8/16

8/16 simplified is equaled to 1/2.

1/2 is equaled to 0.5

The graph of a linear inequality in two variables is the __________ containing all of its solutions.

.line

.half-plane

.parabola

.ellipse

Answers

Answer:

half-plane

Step-by-step explanation:

To draw the line of a linear inequality, we are going to draw a line that divides the coordinate plane into two parts.

Now, while the solution of the inequality lies on a part of the line, the second part of the line does not represent this solution.

Hence, we have a division into two planes. The shaded plane will represent solution to the inequality while the unshaded part will represent the part that is not a solution.

This depends on the sign of the inequality that is present .

The graph of a linear inequality in two variables is the half plain containing all of its solutions.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

In ΔMNO, m = 150 inches, n = 550 inches and o=630 inches.

Now, We know that;

⇒ cos O = m² + n² - o² / 2mn

Substitute all the values, we get;

⇒ cos O = 150² + 550² - 630² / (2 × 150 × 550)

⇒ cos O = - 0.4357

⇒ ∠ O = 115.8°

Thus, The measure of ∠O = 115.8°

Given the coordinate transformation f(x, y) = (- 2x, y) and the domain (0, 5), (8, - 1) and (- 6, 4) what is the range?

Answers

Answer:

{(0, 5), (-16, -1), (12, 4)}

Step-by-step explanation:

Given the coordinate transformation f(x, y) = (- 2x, y) and the domain (0, 5), (8, - 1) and (- 6, 4), to get the range, we will get f(x, y) for all the domain values

For the coordinate (0,5);

f(0, 5) = (-2(0), 5)

f(0, 5) = (0, 5)

For the coordinate (8, -1);

f(8, -1) = (-2(8), -1)

f(8, -1) = (-16, -1)

For the coordinate (-6, 4);

f(-6, 4) = (-2(-6), 4)

f(0, 5) = (12, 4)

Hence the range is {(0, 5), (-16, -1), (12, 4)}

There are 6 cakes.

Each person can eat 1/2 of a cake.

You need to find how many times you can split 6 cakes into 1/2 of a cake.

Obviously, division is the way to go.

6 ÷ 1/2

When dividing by a fraction, you need to turn both parts into fractions.

6/1 ÷ 1/2

Now you skip the first part.

Focus on 1/2

Flip the fraction: 2/1

Now multiply the two fractions together

6/1 *2/1 = 12/1

Therefore 12 people can be at the party.

f(x)=

Answers

Answer:

f

f(x) =-3/4x +2

Step-by-step explanation:

You have points (0,2) and (-4,5) Soo the slope is 5-2/-4-0 = 3/-4

Then f(x) = mx+b. So f(x) = -3/4x + 2 because the y intercept is (0,2).

Answer:

f(x)= -x+2

Step-by-step explanation:

Looking at the graph gives us this information:

SLOPE

you can see that for every 1 unit over, it goes one unit down.

slope = rise / run which would be -1/1 which is also just -1

INTERCEPT

the y intercept is 2

equations are typically written in y=mx+b form (where m is the slope and b is the intercept)

so we have y = -1x +2

you don't need to write the 1 because -1x is the same as -x

sof(x)= -x+2
