If a system of linear equations has one solution, what does this mean about the two lines?
A. The same line
B. Parallel lines
C. Intersecting lines
Answer:
It means two lines intersected.
C is correct
Hope this helps!
:)
If a system of linear equations has one solution, this means that the lines are intersecting lines
Intersecting lines are lines that meet at a point.
For parallel lines, they do not meet at any point. Hence the system of equation formed by these lines does not have a solution
For two intersecting lines, the equation of both lines can be equated to get the unknown variable. This unknown variable will serve as the solution to the system of equation
Hence If a system of linear equations has one solution, this means that the lines are intersecting lines

The volume of a cube is 64 cubic inches. Which expression represents s, the length of a side of the cube?
Recall the formula Cube V = 5
s=/64
CS= 64 +64 +64
S= 64
S=64.64.64
Answer:
Therefore the length of a side of a cube is [tex]\sqrt[3]{64}\ or\ 4[/tex]Step-by-step explanation:
The volume of a cube is expressed as L³ where L is the length of each side of the cube.
Given volume of a cube = 64in³
On substituting;
64 = L³
Taking the cube root of both sides to determine L we have;
[tex]\sqrt[3]{64} = (\sqrt[3]{L})^{3}\\\sqrt[3]{64} = L\\L=4[/tex]
Therefore the length of a side of a cube is [tex]\sqrt[3]{64}\ or\ 4[/tex]

The scatterplot that represents the monthly values of stock ABC can be approximated by a line with a positive slope represents positive correlation. The correct option is C.
What is correlation?The relationship between variables is described by correlation. It can be either strong or weak, as well as positive or negative.
Correlations show that there is a relationship between two variables, but one does not always cause the other to change.
A positive correlation indicates that as one variable increases, so does the other.
In this case, the scatterplot of the monthly values of stock ABC can be approximated by a line with a positive slope, indicating that as the stock's value increases over time, so does the corresponding month. As a result, it is a positive correlation.
Thus, the correct option is C.

A Is congruent to B and B Is congruent to C
A Is congruent to A, B Is congruent to B, C Is congruent to C
Each triangle is a right triangle.
Each triangle is an isosceles triangle.
Answer:
A Is congruent to B and B Is congruent to C
Step-by-step explanation:
Given Figures A, B and C on a coordinate plane with the coordinates below:
Triangle A has points (1, -2), (3, -2), (3, -5).
Triangle B has points (4, 0), (6, 0), (6, -3).
Triangle C has points (4, 0), (6, 0), (6, 3).
The fact that each triangle is a right triangle only shows that the triangles are similar.
For any two shapes to be congruent, they must have in addition to the same shape, the same size.
Therefore, for Triangle A to be congruent to Triangle C, Triangle A must be congruent to Triangle B and Triangle B must be congruent to Triangle C.
Answer:
A = B and B= C

Answer:
c. 107°
Step-by-step explanation:
In the figure attached, Circle P, segments AB and BC, and angle x are shown.
From circumscribed angle theorem, we know that angle ABC and angle x are supplementary, then:
x + 73° = 180°
x = 180° - 73°
x = 107°

In the first case the function could become undefined as x approaches -3 or 3 from either direction. The vertical asymptotes are x = -3 and x = +3.
In the second case, there's only one vertical asymptote, because the denominator can be zero (0) only at x = 0.

PLS HELP!!!!!! In a survey of 4530 U.S. adults, 87% said that they would like to donate more to charity. What is the margin of error for the survey? Round to the nearest tenth of a percent
Answer:
Margin of Error = 1.0% to the nearest tenth of a percent.
Step-by-step explanation:
Margin of Error is the width of the confidence interval about the mean.
It is given mathematically as,
Margin of Error = (Critical value) × (standard Error)
Critical value is obtained from the z-tables at the popular confidence level of 95% and z-tables is used because the sample size, 4530, is large enough to approximate the population properties.
Critical value = 1.960
Standard error = σₓ = √[p(1-p)/n]
p = 87% = 0.87
n = sample size = 4530
σₓ = √[0.87×0.13)/4530]
= 0.0049966876
Margin of Error = 1.96 × 0.0049966876 = 0.0097935078 = 0.00979 = 0.979% = 1.0% to the nearest tenth of a percent.

Aisha is playing a game in which she can gain or lose points on each turn. The table below
shows the points she scores on each of four turns in the game.
Aisha states that her highest score is on Turn 3, because 16 is greater than 3, 10, or 9. Use the
drop-down menus to explain Aisha's mistake.
Answer:
A score of -16 represents the lowest of points for these four turns.
The number for Aisha's highest score will be turn 2 on the number line.
That number is 10.
Step-by-step explanation:
Since the options of the drop down menu are not included, you should choose any option similar to lowest.
Aisha's highest score was obtained in turn 2 and that is 10.
Aisha is comparing absolute terms, that is why she believes that -16 represents a good score, while in reality is the worst she got.
