which is the solution to dis system of equations
x+y=3
x-y=-3
Answer:
Step-by-step explanation:
You are going to want to use the substitution method to solve. Substitute the given value of x (which is x=-3+y) into the equation x+y=3. Now solve the equation for y.You get y = 3. Plug in 3 for x in the other equation. You get x-3=-3 ---> x = 0.
So x = 0, y = 3

Write the equation of the line that passes through the points (7, 4) and (-5, 4). Put
your answer in fully simplified point-slope form, unless it is a vertical or horizontal
line.
Answer:
y = 4
Step-by-step explanation:
note that the y- coordinates of the 2 points are equal, both 4
This indicates that the line passing through them is horizontal with equation
y = c ( c is the value of the y- coordinates the line passes through ), then
y = 4 ← equation of line
the living standard in country x doubles in 12 years. what is its average annual growth rate roughly?
A country will roughly double its gdp in twelve years if its annual growth rate is 5.8 using the rule of 70.
The rule of 70 is used to determine the time it takes a country to double it growth rate.
To double in 12 years =70/12 = 5.8
Therefore, A country will roughly double its gdp in twenty years if its annual growth rate is 5.8 using the rule of 70.
A measure of the rise in the value of an investment or revenue stream over the course of a year is the annual growth rate, often known as the "simple growth rate" or "average annual growth rate (AAGR)".
The formula for calculating annual growth rate divides the total value of annual growth at the beginning of the year by the total value of that growth at the end of the year.

Area of chicken coop =
Answer: 36 ft
Step-by-step explanation:
Find the equation of the line that passes through the point (-4, 11) and is perpendicular to the following line.
y= -2/3x -7
The equation of a line perpendicular to y = (-2/3)x - 7 is y = (3/2)x + 17.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
We know lines perpendicular to each other have slopes that are negative reciprocals of each other.
So, the slope of the perpendicular line to the given line y = (-2/3)x - 7 is (3/2)
which passes through the point (-4, 11) is,
11 = (3/2)(-4) + b.
b = 11 + 6.
b = 17.
∴ y = (3/2)x + 17 is our required line.

Answer:
Step-by-step explanation:
First, multiply the bases together. Then, add the exponent. Instead of adding the two exponents together, keep it the same. This is because of the fourth exponent rule: distribute power to each base when raising several variables by a power.
The value of a house has been increasing by $5000 each year. Write an equation to show how the value will have changed x years from now.
y=(?)x
Answer: y=(1x)^x + 5000
Step-by-step explanation:
So the original equation is y=mx + b
And we know that each year the house increase by 5000, so the b is 5000
For the x which is the slope, we don't know what the slope is so we just say it as x and the ^x is for the number of years, let's say 3 years then it is ^3 and keep increasing like that up.

brayden was a 60% free throw shooter last season. he practiced all through the off-season and has made 12 of the first 16 free throws this season. based on his performance and the results of the simulation, is there convincing evidence that brayden has improved his free-throw percentage? explain.
Yes , there is convincing evidence that Brayden has improved his free-throw percentage when compared to previous year.
Brayden made 60 % free throws last year
P(Making free throw last year) = 0.6
This year,
X% of 16 = 12
X/100 * 16 =12
75%
therefore, this year
P(Making free throw this year) = 7.5
This clearly shows that he improved his free throw percentage compared to last year.
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Probability has been introduced in Maths to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution, where you will learn the possibility of outcomes for a random experiment.

What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to one another.
Both mathematical phrases, equations, and inequalities are created by connecting two expressions.
The equal sign (=) indicates that two expressions in an equation are believed to be equivalent.
The symbols >, <, ≤ or ≥ indicate that the two expressions in inequality are not always equal.
So, the sentence we have is:
the sum of negative 3.2 and 1.5 times a number is a maximum of 8.6
Which can be written in inequality as:
-3.2 + 1.5n ≤ 8.6
Therefore, inequality (C) -3.2 + 1.5n ≤ 8.6 correctly represents the sentence "the sum of negative 3.2 and 1.5 times a number is a maximum of 8.6."

The data are not paired because: o All of these are true o Each element in a sample is measured once: time spent on cell phone o The conclusion pertains to the difference of two independent population means o There are two samples
The correct answer is

None of the tables represent a proportional relationship.
What is a proportional relationship?Proportional relationships are those in which the ratios of two variables are equal. Another way to think about them is that one variable in a proportional relationship is always a constant value multiplied by the other. This is known as the "constant of proportionality."
To determine whether a relationship is proportional, examine the ratios between the two variables. The relationship is proportional if the ratio is always the same. The relationship is not proportional if the ratio changes.
Fir the first table, the ratio varies. Also, the second table isn't constant.

Write and solve an inequality which can be used to determine pp, the number of people who can go to the amusement park.
With $190, a maximum of 12 people can visit the theme park, where admission costs $15.25 per person and parking costs $7.
What is inequality?In mathematics, "inequality" refers to a connection between two expressions or values that are not equal to one another. The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in lieu of the equals sign. It is an illustration of inequity. This shows that the left half, 5x 4, is bigger than the right part, 2x + 3. Finding the x values for which the inequality holds true is what we are most interested in.
Here,
The total amount they can spend=$190
Cost of parking=$7
Cost of ticket per person=$15.25
Let the number of person be x,
15.25x+7≤190
15.25x≤183
