One equation in a system of equations is given in the graph. Which equation below would have to be the second equation so that the system has no solutions?

Answer:

5 cm by 4 cm

Step-by-step explanation

A = L x W    20 = L x W

P = 2L + 2W    (18 = 2L + 2W)/2

9 = L + W      W = 9 - L

20 = L (9 - L)    20 = 9L - L^2

L^2 - 9L + 20 = 0    (L - 4)(L - 5) = 0

L = 4  L = 5

The longer one is the length, so L = 5, and W = 4.

Question 3 - true

Step-by-step explanation:

It is onto function.

Answer:

[tex]\frac{63}{3} = 21[/tex]

So in every 1min he eat 21 hotdogs

in 3min he can eat 63 hotdogs

in 4min he can eat 84

because 21 + 21 + 21 + 21 = 84

Answer:

The way I learned was by determining the denominator such 7/10 would be 0.7 because 7 is located in the tenths place.

/G/To convert a fraction to a percent, first divide the numerator by the denominator. Then multiply the decimal by 100 .

Answer:

5/4 x 2/3

it just means take the 1 and make it 4/4 instead then add the other 1/4

The proof of the law of sines was completed correctly by Kamala and the final step is to write the expression a/sinA = c/sinC.

The law of sines simply means the ratio between the sine of an angle and the side that's opposite it.

From the complete question, it can be deduced that the proof was correctly completed by Kamala. In her case, she correctly wrote that asinC = csinA and the next expression for the conclusion is that a/sinA = c/sinC.

Given the second difference, the table is quadratic.

A linear function is a function that has a single variable raised to the power of 1. An example is x + 2. A quadratic function is a function that usually has a single variable and it is raised to the power of 2. An example is 2x² + 10x + 25.

First differences:

21 - 11 = 10

35 - 21 = 14

53 - 35 = 18

75 - 53 = 22

Due to the fact that the first difference is not the same, the function is not a linear function.

Second difference:

14 - 10 = 4

18 - 14 = 4

22 - 18 = 4

Due to the fact that the second difference is fairly constant, the function is a quadratic function.

Answer:

Answer:1200

Step-by-step explanation:

Consider the cost price to be x.

1st equation x - (15/100)x = x + (20/100)    ...15% discount and gain of 20%

2nd equationx - (25/100)x = x + 120           ....25% discount and a gain of 120Rs

Solving above equations by subtracting we get

(10/100)x = (20/100)x - 120

Solving LHS and RHS..(10/100)x =120

x=1200

Answer:

100 feet in length

Step-by-step explanation:

Given the following question:

[tex]A=s^2[/tex]

In order to find the area of the square we have to multiply two of the lengths by itself.

[tex]A=s^2[/tex]
[tex]A=100^2[/tex]
[tex]A=100\times100[/tex]
[tex]100\times100=10000[/tex]
[tex]=10000ft^2[/tex]

Which means one side of the given square is "100 feet."

2x = 2 x 25?

50 + ? = 150

50 + 100 = 150

x = 50?

2x + 50 = 150

2 x 50 + 50 = 150

100 + 50 = 150

The measure of x is 50.

Vertical angles are generated by the junction of two straight lines that are not contiguous. Vertical angles are positioned across from each other in the corners of the "X" created by two straight lines. Because they are opposite each other, they are also known as vertically opposite angles.

Using Vertical Angle property as

(50+ 2x) = 150

So, subtract 50 from side we get

50 + 2x - 50= 150 - 50

2x = 100

Now, divide both side by 2 we get

2x/2 = 100 / 2

x = 50

Answer:

350mlliliters = 0.35liters

9liters = 9000milliliters

Answer:

Your equation is [tex]y = -1x + \frac{1}{2}[/tex] or [tex]y = -1x + .5[/tex]

Equation of the line: [tex]y=mx+b[/tex]

Add in the slope in place of ([tex]m[/tex])

[tex]y=-1x+b[/tex]

Add in the x value of the given point in place of ([tex]x[/tex])

[tex]y=(-1)\frac{1}{2}+b[/tex]

Add in the y value of the given point in place of ([tex]y[/tex])

[tex]0=(-1)\frac{1}{2} + b[/tex]

—

Solve:

[tex]0=(-1)\frac{1}{2} +b[/tex]

Multiply -1 and [tex]\frac{1}{2}[/tex]

[tex]-1 *\frac{1}{2}=-\frac{1}{2}[/tex]

So,

[tex]0=-\frac{1}{2} +b[/tex]

Now, add [tex]-\frac{1}{2}[/tex] to 0

      [tex]0=-\frac{1}{2} +b[/tex]

     [tex]+\frac{1}{2}[/tex]   [tex]+\frac{1}{2}[/tex]

---------------------------

     [tex]\frac{1}{2} = b[/tex]

Replace ([tex]b[/tex]) with [tex]\frac{1}{2}[/tex]

Your equation is [tex]y = -1x + \frac{1}{2}[/tex] or [tex]y = -1x + .5[/tex]
