2. Find the area in square meters of the figure<br> below? Use 3.14 for.<br> 6m
Illusion [34]

Answer:

in order to find the area, we should break up the figure. you can see that in the image we have a quarter of a circle and a square. here are the areas for each of these shapes

square:

area = {x}^{2}

circle:

area = \pi {r}^{2}

but since we only have a quarter of this circle we need to divide the area by 4 so the formula becomes

\frac{\pi {r}^{2} }{4}

now we can plug in our numbers

we are given 6 m for our radius or length of square

the square will be (6)^2 = 36 m^2

now onto our circle

π(6)^2/4 = 28.26 m^2

now add these two shapes together to find the total area = 64.26 m^2

Which graph best represents the solution to the system of equations shown below?
goldfiish [28.3K]

First find the x and y values because where the lines will intersect, they share the point of the intersection so they will share the x and y coordinates.

Rearrange equations

4x + y = 19

- 2x + y = 1

To cancel y, we must do equation 1 minus equation 2. Similarly:

4x -  - 2x = 4x + 2x = 6x

19 - 1 = 18

6x = 18

x = 18 \div 6 = 3

So the x coordinate is 3.

The y coordinate can be found with substitution of x into one of the equations:

y = 2x + 1 = 2(3) + 1 = 7

So where the two lines intersect is at the point (3, 7), which is the solution to the equations.

1. Refer to the equation 3x − 4y = 12. (a) Create a table of values for at least 4 points.
Zinaida [17]

Answer: THE TABLE OF VALUES IS ATTACHED.

Step-by-step explanation:

Given the following equation:

3x-4y = 12

You can solve for the variable "y":

3x-4y = 12\\\\-4y=-3x+12\\\\y=\frac{3}{4}x-3

Now you can give values to "x" and substitute each into the equation to find the corresponding value of "y".

For x=-1:

y=\frac{3}{4}(-1)-3=-3.75

For x=0:

y=\frac{3}{4}(0)-3=-3

For x=1:

y=\frac{3}{4}(1)-3=-2.25

For x=2:

y=\frac{3}{4}(2)-3=-1.5

With this values you can make the table shown attached.
