What is the best way to describe the solution of this system of equations?
2x - 5y = 8
5y = -2x + 8
There are infinitely many solutions
There is one solution (4,0).
There are no solutions of the system.
There is one solution (0,4).

Answers

Answer 1

Answer:

There is one solution (4,0).

Answer 2

Answer:

x = 4 and y = 0

:-))

Step-by-step explanation:

2x - 5y = 8

x = 8 + 5y .........(1)

2

5y = -2x + 8

x = 8 - 5y ........(2)

2

get from 1 and 2

8 + 5y = 8- 5y

2 2

or, 10y = 0

or, y = 0

put the value of y in 1

x = 8 + 0

2

or, x = 4

A circle is cut in half and removed. What is the approximate area (shaded region) of the remaining portion of the circle in square feet? There is a picture of a circle with a line through the middle showing 12 feet.
12 feet ( A=pie(3.14)r^2)
Options are: A. 60 ft2 B. 120 ft2 C. 225 ft2 D. 450 ft2

Answers

Answer:

Step-by-step explanation:

area of a whole circle is pi [tex]r^{2}[/tex]

diameter is 2*r

1/2 * pi * [tex]6^{2}[/tex]   will find the area of 1/2 of the circle that has a diameter of 12'

Answer:

0.04

Step-by-step explanation:

1. 9/10 = 0.9 and 13/15 = 0.86

2. Subtract 0.9 and 0.86

3. You should end up with 0.04

Remember when a number goes like 0.86666666666 to use 0.86 or if it has 0.86666666667 to use 0.87 because you would be simplifying it.

Monica had a savings account that paid her an interest rate of 4%. After she had this account for 12 years, she had received $192 in interest. How much money had she put into the account at the beginning of the 12 years?

Answers

Answer:

Money she put in her account = $400

Step-by-step explanation:

As, to find the interest the formula is PTR/100 = I

Where P = Principcal

And T = time (in years)

And R = rate

And I = interest

So here p is not present we need to find it

R = 4%

And T = 12 years

And I = $192

= p x 4 x 12 /100 = 192

P x 4 x 12 = 19200

P x 48 = 19200

P = 19200/48

P = 400

So Principcal = $400

Find the slope intercept equation of the line

PLEASE HELP ME!!!!!

Answers

Answer:

y = -x + 6

Step-by-step explanation:

Slope-intercept form:

y = mx + b, where m is slope and b is y-intercept

We see on the graph y-intercept is b = 6,  point (0.6)

To find the slope we need a second point, choosing point (5, 1)

Using slope formula:

m = (1- 6)/(5 - 0) = -5/5 = -1

So the line is:

y = -x + 6

Answer:

y = -4/5x + 5

Step-by-step explanation:

the formula for slope intercept is y=mx+b.

m represents the slope of the line and b is the y intercept. all you have to do is replace those variables.

the y intercept is the point where the line crosses the y-axis (the line going up and down on the graph). (0,5) is the y intercept and so 5 would replace b in y=mx+b

so far we have y=mx+5

The slope is the vertical change between two points is called the rise, and the horizontal change is called the run. Starting from a point on the line you would move vertically until you're in line with another point. In this case, let's just use (0,5) from before. You would go up four to line up with a point. Then, move horizontally to meet up with the point and count the units, which is five here. And so, the slope would be 4/5.

And then you get the equation:

y=4/5x+b

Melanie earns $7 per hour when she
baby-sits. An equation for this relation
is w = 7h, where h represents the
number of hours and w represents
Melanie's wage in dollars.
a) Use the equation to create a table
of values.
b) In one week, Melanie earned $105.
How many hours did she baby-sit?
c) In one month, Melanie baby-sat for
24 h. How much did she earn
from baby-sitting in that month​

Answers

Answer:

A) We know that she make $7 per hour, with this we can make a table:

1hr | $7

2hr | $14

3hr | $21

etc...

B)  If in one week she earns $105 and 1w = 7h (1hr = $7) holds true, that means that we have to divide 105 by 7 which gives us 15hrs

C) If she baby-sat for 24hrs, we just have to multiply that by 7 and we get $168

Number 12. Find angle ADE

Answers

Answer:

ADE=59º

Step-by-step explanation:

4x+15+13x+7=90

17x+22=90

17x=68

x=4

angle B=angle ADE so we plug in x=4 into 13x+7

13(4)+7=59º

Angle ADE = 59 degrees
(4x+15)+(13x+7)=90degrees
17x+22=90degrees
68=17x
4=x
Angle DBC= 59 degrees
Angle DCB = 90degrees
Triangle = 180degrees
90+59=149
180-149=31 degrees
Angle EDC = 31
90-31=59 degrees
Angle ADE = 59 degrees

You are filling a 2-liter bottle with liquid from full 80-milliliter containers. How many containers will it take to fill the 2-liter bottle?

Answers

Answer:

25 bottles

Step-by-step explanation:

2 litres=2000 milliliters

2000/80=25 (or) 80x25=2000

The amount of containers it will take to fill the 2-liter bottle is 25 containers.

Given the following data:

Volume of bottle = 2 LitersVolume of containers = 80 milliliter

To determine the amount of containers it will take to fill the 2-liter bottle:

In this exercise, you're required to determine the amount of 80-milliliter containers that would be required to fill the 2-liter bottle.

First of all, we would convert the volume in liters to milliliter.

Conversion:

1 Liter = 1000 millimeters

2 Liter = 2000 millimeters

Now, we can find the amount of containers by using the formula:

[tex]Number\;of\;containers = \frac{Volume \;of\;bottle}{Volume \;of\;containers}[/tex]

Substituting the parameters into the formula, we have;

[tex]Number\;of\;containers = \frac{2000}{80}[/tex]

Number of containers = 25 containers
