how do you solve y=3-x
2x+y=6

Answers

Answer 1

Answer:

x=3 y=0

Step-by-step explanation:

This is called system of innequalities

we know y= 3-x and we substitute that into 2x+y=6 and we get

2x+3-x=6 we solve and get x=3

then we substitute x into the first equation and we get y=3-3 and get 0

x=3 y=0

Vol = ener
7 cm

Answers

Answer:

Volume of the sphere ( V ) = 1436.02 cm³

Step-by-step explanation:

Explanation:-

Given that the radius of the sphere r = 7 cm

Volume of the sphere

                  [tex]V = \frac{4}{3} \pi r^{3}[/tex]

                 [tex]V = \frac{4}{3} \pi (7)^{3}[/tex]

                 [tex]V = \frac{4}{3} X3.14 X (7)^{3} = 1436.02[/tex]

                 V = 1436.02 cm³

Volume of the sphere

                  V = 1436.02 cm³

Answer:1436.8

Step-by-step explanation:

4/3πr^3

Substitute the 7 with the ”r”

4/3xπx7^3

Kim picked 250 pounds of pears yesterday and 287 pounds of pears today. What is the percentage increase of

amount of peas picked by Rim

Answers

Given:

Kim picked 250 pounds of pears yesterday and 287 pounds of pears today.

To find:

The percentage increase of  amount of pears picked by Kim.

Solution:

We know that,

[tex]\%\text{ increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]

[tex]\%\text{ increase}=\dfrac{287-250}{250}\times 100[/tex]

[tex]\%\text{ increase}=\dfrac{37}{25}\times 10[/tex]

[tex]\%\text{ increase}=\dfrac{370}{25}[/tex]

[tex]\%\text{ increase}=14.8[/tex]

Therefore, the percentage increase of  amount of pears picked by Kim is 14.8%.

What is the slope of a line parallel to the line whose equation is x+2y=10

Answers

Answer: slope =

-1/2

Step-by-step explanation:

Since they are parallel, they will never intersect. The only way this is possible is if they have the same slope. All you had to do was get y by itself and find the number next to the x. Subtract the ten and the 2y and pass them to their opposite sides that way it will be x-10= -2y. After that, divide the -2 by everything on the x side. The final equation is -1/2x -10= y.

Graph the line that passes through the points (-9,5) and (-9,-5) and
determine the equation of the line.

Answers

Answer:

x=-9

Step-by-step explanation:

M(slope)=y2-y1/x2-x1

m=-5-5/-9+9

m= -10/0

This means the slope is undefined. Whenever the slope is undefined, the line is vertical and is passing through the x-axis and parallel to the y-axis. Take the given coordinate (-9,5) and all you do is put x= -9. That's the equation of the line.

Answer:

x = 1/2

b = 12

Step-by-step explanation:

In order to solve for x you have to divide by x

2 = 4x  divide by x

2/4 = x

simplify and you get 1/2

same thing goes for b. You need to leave b by itself. so subtract 24 from both sides and you get -12. divide both sides by -b and a negative divided by a negative turns into a positive b by it self holds a value of 1

Find the slope of the following graphs.

A. 2/3
B. 3/2
C. 3
D. - 2/3

Answers

Answer:

Answer is A

Step-by-step explanation:

The slope of the shown line passing through points (3,2) and (0,0) is 2/3. The answer is option A.

Given the points (3,2) and (0,0), we can calculate the change in y and change in x as follows:

Change in y = 2 - 0 = 2

Change in x = 3 - 0 = 3

Now, we can substitute these values into the slope formula:

Slope = (change in y)/(change in x) = 2/3

Here, the line has a positive slope, indicating that as x increases by 1, y increases by 2/3.

This means that the line is ascending from left to right, sloping upwards.

Therefore, the slope of the line passing through points (3,2) and (0,0) is 2/3.

Hence, the answer is option A.
