Answer:
(3, - 2 )
Step-by-step explanation:
Given the 2 equations
4x - 2y = 16 → (1)
y = - 5x + 13 → (2)
Substitute y = - 5x + 13 into (1)
4x - 2(- 5x + 13) = 16 ← distribute and simplify left side
4x + 10x - 26 = 16
14x - 26 = 16 ( add 26 to both sides )
14x = 42 ( divide both sides by 14 )
x = 3
Substitute x = 3 into (2) for corresponding value of y
y = - 5(3) + 13 = - 15 + 13 = - 2
solution is (3, - 2 )

The scatter plot shows the height x (in inches) and the weight y (in pounds) of 10 people. Find the weight of the person who is 63 inches tall. Then find the height of the person who weighs 135 pounds.
PLEASE HELP QUICK!!!!

Given:
Scatter plot shows the height x (in inches) and the weight y (in pounds) of 10 people.
To find:
The weight of the person who is 63 inches tall. Then find the height of the person who weighs 135 pounds.
Solution:
In the given scatter plot,
x = height (in inches)
y = weight (in pounds)
First we need to find the weight of the person who is 63 inches tall.
If height of a person is 63 inches, then x = 63.
From the given graph, it is clear that y = 110 at x = 63.
Therefore, the weight of the person who is 63 inches tall is 110 pounds.
Now, we need to find the height of the person who weighs 135 pounds.
If weight of a person is 135 pounds, then y = 135.
From the given graph, it is clear that x = 66 at y = 135.
Therefore, the height of the person who weighs 135 pounds is 66 inches.

First creat two inequalities with the values given using x as the number of student ticked and y as non student.
X + y = 292 tickets
Notice how this measures only the tickets
The next equation is the cost and total earnings.
1x + 3y = $470
Notice these values are in dollars not tickets.
Now pick one equation and solve for one variable. We will use the x variable and the first equation.
X + y = 292
Get x by itself to find the equality by subtracting y from both sides.
X = 292 - y
Now we have a value for x that we can use to solve the second equation. Plug the right side of the equation in for the x value since they are equal
1(292-y) + 3y = 470
Now solve for y
292 - y + 3y = 470
2y + 292 = 470
2y = 178
Y = 89$
Now use this value for y in the second equation again.
X + 3(89) = 470
X + 267 = 470
X = 203$
This means that student ticket sales totals 203$ while non student totals 89$
In this specific case this also means that:
Student tickets sold = 203 tickets
Non student tickets sold = 89 tickets

Distance covered is 45mm which is 0.045m or 0.45cm but the displacement is very small so use mm instead. Time taken (t) to cover the distance is 85s. V=45/85

Step-by-step explanation:
Explanation:
1. Turn it into a fraction (16/20).
2. Divide the numerator (16) by the denominator (20). (16÷20=0.8)
3. Subtract the decimal (0.8) from 1. (1-0.8=0.2)

If the simple interest on $6,000 for 3 years is $1,620, then what is the interest rate?
Answers
Answer:
Interest rate: 9%
Step-by-step explanation:
Using the simple interest formula: A=P(1+rt)
A=Final amount
P=Principal amount
r=rate
t=time (years)
We just need to put in the information we have from the question and solve for r.
7,620=6000(1+r3)
7,620/6000=1+r3
1.27=1+r3
0.27=r3
r=0.09
r=9%

Answers
Answer:
1. last choice
2. first choice
Step-by-step explanation:
First ImageThe reason why it is the last choice because when times keep going as distance also keeps increasing as well. But the last choice says that run at the end of track then turn around and run back. That means there must be a decreasing distance and a maximum value as well.
Therefore the only with max point/vertex is the absolute value which matches the last choice.
Second ImageFirst choice because the car straight forwards without any change. The car runs with a steady speed but the distance will keep changing without any change of distance.
So the answer is first choice.

1. Compare the strengths and weaknesses of the horizontal and vertical methods for adding and subtracting polynomials. Include common errors to watch out for when using each of these methods.
2. Explain why you cannot use algebra tiles to model the multiplication of a linear polynomial by a quadratic polynomial. As an added challenge, develop a model similar to algebra tiles that will allow you to show this multiplication. Describe an example of your model for the product (x + 1)(x2 + 2x + 2). 3. Imagine that you are teaching a new student how to multiply polynomials. Explain how multiplying polynomials is similar to multiplying integers. Then describe the key differences between the two. 4. If you multiply a binomial by a binomial, how many terms are in the product (before combining like terms)? What about multiplying a monomial by a trinomial? Two trinomials? Write a statement about how many terms you will get when you multiply a polynomial with m terms by a polynomial with n terms. Give an explanation to support your statement.
Answers
1.Each method works differently the angles inside them is what matters.
2. Manipulating algebra tiles can help people solve linear equations
3.Distribute each term of the first polynomial to every term of the second polynomial. Remember that when you multiply two terms together you must multiply the coefficient (numbers) and add the exponents. But with Integers you multiply two integers with different signs
4.So you know how
A monomial is a number, a variable or a product of a number and a variable.
multiply each term in one polynomial by each term in the other polynomial

Write an equation in slope-intercept form of the line that passes through (2,-2) and slope of -4
Answers
Answer:
y = - 4x + 6Step-by-step explanation:
Starting with the point-slope form of the equation {y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope}:
m = -4
(2, -2) ⇒ x₀ = 2, y₀ = -2
So, the point-slope form of the equation:
y + 2 = -4(x - 2)
Therefore:
y + 2 = - 4x + 8 {subtract 2 from both sides}
y = - 4x + 6 ← the slope-intercept form of the equation
