A system of equations is shown on the graph below.

On a coordinate plane, 2 lines intersect at (negative 1, 2).

How many solutions does this system have?
no solutions
one unique solution
two solutions
an infinite number of solutions

Answers

Answer: One unique solution.

Step-by-step explanation:

When we have a system of linear equations like:

y = a*x + b

y = c*x + d

We have 3 possibilities:

1) There is only one solution, this happens when in the graph, the lines intersect at only one point.

2) There is no solution, in this case, the lines never intersect, this would be the case of two parallel lines.

3) We have an infinite number of solutions, this happens when both lines intersect in an infinite number of points, and this can only happen when both lines are the same line.

In this case, we know that we have two lines and they intersect in only one point, (-1, 2)

Then we have only one solution, and the solution is (-1, 2)

A diameter is a chord.
True or false and why?

Answers

Answer:

true.

A chord that passes through the center of a circle is called a diameter and is the longest chord.

Step-by-step explanation:

A diameter satisfies the definition of a chord, however, a chord is not necessarily a diameter. This is because every diameter passes through the center of a circle, but some chords do not pass through the center. Thus, it can be stated, every diameter is a chord, but not every chord is a diameter.

If the simple interest on $7000 for 3 years is $1890, then what is the interest rate?

Answers

Answer:

0.09 or 9%

Step-by-step explanation:

I = Prt

Given:

I = 1890

P = 7000

t = 3

Work:

I = Prt

r = I/(Pt)

r = 1890/(7000 x 3)

r = 1890/21000

r = 0.09

Lin solved the equation 8(x-3)+7=2x(4-17) incorrectly.

Find the errors in her solution. What should her answer have been?

Lin's Steps - 8 (x-3) + 7 = 2x (4 - 17)
8 (x-3) + 7 = 2x (13)
8x - 24 + 7 = 26x
8x - 17 = 26x
-17 = 34x
-1/2 = x

Answers

Answer:

Step-by-step explanation:

Answer:

1/2 = x

Step-by-step explanation:

8 (x-3) + 7 = 2x (4 - 17)

8 (x-3) + 7 = 2x (-13)

8x - 24 + 7 = -26x

8x - 17 = -26x

The chart below displays information regarding the number of picture frames sold by a store in a given month.
According to the chart, what fraction of the frames sold during the four-month period were sold in march? Hint: Determine the total number of frames sold and then write a fraction with March/total and simplify.
a. 3/10
b. 1/4
c. 1/5
d. 1/6
e. 1/10

Answers

In the chart, rectangle white inside is 100 and solid is 50. So they sold 250 in March out of 1,000 total in a 4 month period. Answer is b. 1/4

Answer:

1/4

Step-by-step explanation:

Calculate the frames of each month:

January = 350

February = 100

March = 250

April = 300

Solve

[tex]\frac{March}{Total} = \frac{250}{350 + 100 + 250 + 300} = \frac{250}{1000}[/tex]

Simplify

[tex]\frac{250}{1000} = \frac{25}{100}= \frac{1}{4}[/tex]

A university has 40,140 students. In a random sample of 210 students, 14 speak three or more languages. Predict the number of students at the university who speak three or more languages.

Answers

Answer:

2676 students

Step-by-step explanation:

Total number of students =. 40,140

During study:

Sample size = 210

Number of samples who speak 3 or more languages = 14

Proportion who speak 3 or more languages :

14 / 210 = 0.0666666

Applying the proportion to the total. Population :

0.0666666 * total number of students

0.0666666 * 40140

= 2675.997324

= approximately 2676 students

3) When Jackie took her children to the movie theater, she bought one box of candy and three small drinks for
$14.75. When Alex went to the same theater and bought two boxes of candy and five small drinks, he paid
$26.
a) Set up a system of equations to model this situation. Be sure to define the variables that you use.
b) Determine, algebraically, the cost for one box of candy and one small drink

Answers

Answer:

c + 3d = 14.75

2c + 5d = 26

A box of candy is $4.25 and a drink is $3.50

Step-by-step explanation:

Let c represent the cost of a box of candy and let d represent the cost of a drink

c + 3d = 14.75

2c + 5d = 26

Solve by elimination by multiplying the top equation by -2

-2c - 6d = -29.5

2c + 5d = 26

Add them together

-d = -3.5

d = 3.5

Plug in 3.5 as d into one of the equations to solve for c

c + 3d = 14.75

c + 3(3.5) = 14.75

c + 10.5 = 14.75

c = 4.25

So, a box of candy is $4.25 and a drink is $3.50
