What is the solution to the system of equations
Answer:
(2, - 5 )
Step-by-step explanation:
Given the 2 equations
y = - 3x + 1 → (1)
4x + y = 3 → (2)
Substitute y = - 3x + 1 into (2)
4x - 3x + 1 = 3
x + 1 = 3 ( subtract 1 from both sides )
x = 2
Substitute x = 2 into (1) for corresponding value of y
y = - 3(2) + 1 = - 6 + 1 = - 5
solution is (2, - 5 )
In the following figure, the value of x is

is this relationship proportional why or why not?
Answer:
no
Step-by-step explanation:
to be proportional, every step of 1 in the upper row, must equal an equal step in the lower row.
from 1 to 2: +15
from 2 to 3: +18
not the same so not proportional

Express each rate as a unit rate.
a. 32 teams in 4 divisions
b. $2.70 for 15 ounce
Answer:
To solve for the unit rate, know that the final answer must be out of 1. Or it is the quantity or amount of something per unit of measurement.
For instance in the above question, the unit rate for 32 teams in 4 divisions would be 8 teams per division.
Likewise for the other question it would be 270/15.

here is an example jy26903
Answer:
I meant an example for a problem like the one you posted.
Either way, I'll try to help.
in the example, you're finding out what percentage of 352 is 226.6.
So divide 226.6 (The number that you're using to find what percentage it is of 352) by 352( the number you're finding the percentage of.)
226.6/352= 0.64375, and multiply the quotient by 100 to get 64.375. You're rounding up by the nearest hundredth, so the 7 turns to 8. (5 or more means rounding up.)
your final answer for the example is 64.38%. So Try that with your next problem.
For the one you're working on, divide 110.9 by 100 and then multiply it by 419.
You'll get 464.671.
Your grandparents started a savings account with $10,000 the day you were born. It earns 5% annually compounded monthly. How much will you have when you turn 18?
Answer: You will have $24,551.84 when you turn 18.
Step-by-step explanation:
Formula for accumulated amount earned in t years:
[tex]A=P(1+\dfrac{r}{12})^{12t}[/tex], where P = principal value, r = rate of interest
Given: P= $10000, r = 5% t = 18 years.
Substitute all values in formula, we get
[tex]A=10000(1+\dfrac{0.05}{12})^{12\times18}\\\\=10000(1.004167)^{216}\\\\=10000(2.45518445623)\approx24551.84[/tex]
Hence, you will have $24,551.84 when you turn 18.

Use the equation to identify a and b * a = 1/5 and b = 3 a = 3 and b = 1/5 a= 1/5 and b =1 a = 1 and b = 3
Answer:
[tex]a = 3[/tex]
[tex]b = \frac{1}{5}[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 3(\frac{1}{5})^x[/tex] --- Missing from the question
Required
Identify a and b
The given equation is an exponential function and the general form is:
[tex]f(x) = ab^x[/tex]
When [tex]f(x) = ab^x[/tex] is compared to [tex]f(x) = 3(\frac{1}{5})^x[/tex]
We have that: [tex]a = 3[/tex] and [tex]b = \frac{1}{5}[/tex]
Jane sold a house for $160,000 that she listed. Her broker charges a % commission and she receives 60% of the commission. How much did Jane receive?
Jane gets 5,760.
What is commission?Commissions are a form of variable-pay remuneration for services rendered or products sold.
Given:
House sold for $160,000 with a listing commission of 6%
So, full commission
=160,000*0.06
= 9, 600
And, jane's share will be
=9600 * 0.60
=5,760
Hence, jane's share will be 5,760.

given f(x)=50+30x, find f(1), f(2), and f(3)
Please help
The numbers inside the parentheses are the x values. Replace x with each number and solve.
F(1) = 50 + 30(1)= 50+ 30 = 80
F(2) = 50 + 30(2)= 50 + 60 = 110
F(3) =!50 + 30(3)= 50 + 90 =140
The value of the function f(x) = 50 + 30x at x = 1, 2, and 3 will be 80, 110, and 140.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
The function is given below.
f(x) = 50 + 30x
The value of the function at x = 1, will be
f(1) = 50 + 30 × 1
f(1) = 50 + 30
f(1) = 80
The value of the function at x = 2, will be
f(2) = 50 + 30 × 2
f(2) = 50 + 60
f(2) = 110
The value of the function at x = 3, will be
f(3) = 50 + 30 × 3
f(3) = 50 + 90
f(3) = 140
Thus, the value of the function f(x) = 50 + 30x at x = 1, 2, and 3 will be 80, 110, and 140.

A plant is 3 inches tall when you purchase it and grows 2 inches per month. Write an equation in slope intercept form that represents the height y(in inches) of the plant after x months.
Answer:
y = 3 + 2x
Step-by-step explanation:
In this scenario, we are given two values which are the initial height of the plant and its growth height. Then we are given a variable which is the number of months (x) that are unknown for us. The growth height needs to be multiplied by the number of months to know how much it has grown in that time period. Then we add this value to the initial height of the plant to calculate the total height (y) of the plant after x number of months. We can apply this information to form the following equation in slope-intercept form.
y = 3 + 2x

How can you see that a reflection could work without knowing where the line of reflection is? If you get the answer right I'll paypal, venmo or cash app you $50. So drop your paypal, venmo or cash app along with your answer.
Note how going from R to S to T to U has us going counterclockwise. In contrast, going from R' to S' to T' to U' has us going the opposite direction going clockwise. This change in orientation strongly implies that a reflection has been done. Reflections always flip orientation.
-----------------------------------------
Here's how we can find the line of reflection.
Draw a line segment from point R to point R'. Mark the midpoint of the segment as point A
Repeat this process to form a segment from S to S'. Mark the midpoint as point B.
The line of reflection will pass through points A and B. This is because the line of reflection is equally distant between the original point (such as point R) and its reflected point (such as R'). This must mean that the line of reflection goes through the midpoint of segment UU' and also segment TT'.
Refer to the diagram below.

Answer:
option D
Step-by-step explanation:
a² - b² = (a + b) (a - b)
625 = 5 * 5 * 5 * 5 = 5⁴
y⁴ - 625 = y⁴ - 5⁴
= (y²)² - (5²)² {a = y² ; b = 5²}
= (y² + 5²)(y² - 5²)
= (y² + 25)(y² - 5²)
= (y² + 25)(y + 5)(y - 5)
