How many solutions does the system have? { y = − 7 x + 8 y = − 7 x − 8 ⎩ ⎪ ⎪ ⎨ ⎪ ⎪ ⎧ ​ y=−7x+8 y=−7x−8 ​

Answers

The system of equations y =−7x + 8  and y = −7x − 8 ​ have no solution

How many solutions does the system have?

From the question, we have the following parameters that can be used in our computation:

y =−7x + 8

y = −7x − 8 ​

Subtracting the two equations

We have

y - y = -7x + 7x + 8 + 8

When the like terms are evaluated, we have

0 = 16

The above equation is false

This means that the equation has no solution

A total of 190 people attended the opening night of a school
musical. Student tickets cost $4.50 each while general
admission tickets cost $6 each. If total sales were $996, how
many general admission tickets were sold?

Answers

Answer:

94

Step-by-step explanation:

x=student tickets y=general admission

We can write the two following equations

x+y=190

4.5x+6y=996

I am going to solve this through substitution

We first need to get a variable by itself

x+y=190

x-190= -y

-x+190=y

We can plug this value in for y into the second equation

4.5x+6(-x+190)=996

4.5x-6x+1140=996

-1.5x= -144

x=96

Now that we know that x=96 we can plug this value into any of the two beginning equations and solve for y

96+y=190

y=94

Tom is applying for a visa. He has to pay £1,700 for the visa as well as a 11% charge on the visa price for an on-the-day service. If Tom has 1 year to save, how much money should he save per month to be able to cover his costs? Round your answer to the nearest £10.

Answers

Step-by-step explanation:

G1=Go(1+r)^n

G1=1700(1+11%)^1

G1=1700(1+0.1)

G1=1700*0.1

A particular employee arrives at work sometime between 8:00 a.m. and 8:30 a.m. Based on past experience the company has determined that the employee is equally likely to arrive at any time between 8:00 a.m. and 8:30 a.m. Find the probability that the employee will arrive between 8:15 a.m. and 8:25 a.m. Round your answer to four decimal places, if necessary.

Answers

Answer:

0.3333 = 33.33% probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value between c and d is given by:

[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]

A particular employee arrives at work sometime between 8:00 a.m. and 8:30 a.m.

We can consider 8 am = 0, and 8:30 am  = 30, so [tex]a = 0, b = 30[/tex]

Find the probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Between 15 and 25, so:

[tex]P(15 \leq X \leq 25) = \frac{25 - 15}{30 - 0} = 0.3333[/tex]

0.3333 = 33.33% probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

A dance team decided to sell fruit snacks to raise money for an upcoming competition. The dancers charged $3.00 for each fruit snack they sold. In 4 days, they sold 24 packs of fruit snacks. How much money could the team earn for seven days at that same rate?

Answers

Answer:

126 dollars

Step-by-step explanation:

(i'm gonna be doing my work here, dont mind me LOL)

okay, so they sold 24 packs in 4 days. divide 24 by 4 and you get 6. multiply 6 by 3 and you get 18.

now, multiply 18 by seven and you get 126.

bam!! the dance team could earn 126$ in 7 days ^__^ hope you get an A!

Answer:

$126

Step-by-step explanation:

Let x = packs sold in 7 days

Set up a proportion.   days/days = packs/packs

4/7 = 24/x

4x = 24(7)  = 42 packs sold in 7 days

At $3/pack, the amount earned in 7 days =  3(42) = $126

The point M is the midpoint of LN where M(-12, 6) and N (-2,-5).
What are the coordinates of point L?

Answers

Answer:

The coordinates of point L are:

(x₁, y₁) = (-22, 17)

Step-by-step explanation:

We know that the Midpoint Formula is given by:

[tex]\left(x,\:y\right)=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

In our case:

M(-12, 6) is the midpoint. Thus,

(x, y)  = (-12, 6)

N(-2, -5) is the second point, Thus,

(x₂, y₂) = (-2,-5)

We have to determine the coordinates of point L.

Let (x₁, y₁)  be the coordinates of point L.

substituting (x, y)  = (-12, 6), (x₂, y₂) = (-2,-5) in the Midpoint Formula

[tex]\left(-12,\:6\right)=\left(\frac{-2+x_1}{2},\:\:\frac{-5+y_1}{2}\right)[/tex]

Determining the x₁ coordinate of the point L

[tex]\frac{-2+x_1}{2}=-12[/tex]

[tex]-2+x_1=-24[/tex]

Add 2 to both sides

[tex]-2+x_1+2=-24+2[/tex]

Simplify

[tex]x_1=-22[/tex]

Determining the y₁ coordinate of the point L

[tex]\frac{-5+y_1}{2}=6[/tex]

[tex]-5+y_1=12[/tex]

Add 5 to both sides

[tex]-5+y_1+5=12+5[/tex]

Simplify

[tex]y_1=17\:\:\:[/tex]

Therefore, the coordinates of point L are:

(x₁, y₁) = (-22, 17)

What are linear equations?

Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Given the equations y = 3x + 1

y = 2x - 4

comparing both equations for equal values of y,

3x + 1 = 2x - 4

3x  - 2x = -4 - 1

x = -5

substitute value of x in equation,

and y = 3x + 1

y = 3(-5) + 1

y = -14

Hence the value of x is -5.
