What is the solution to the system of equations graphed below? y=-3/2x+2 y = 5x + 28 A. (4,8) B. (0.2) C. (-8,4) D. (-4.8)
Answer:
(-4, 8)
Step-by-step explanation:
y = -1.5x + 2
y = 5x + 28
y + 1.5x = 2
y - 5x = 28
6.5x = -26
x = -4
y = 5(-4) + 28
y = -20 + 28
y = 8
Two types of alien live on the planet Starlight: Zoomas have 3 eyes and 2 legs and Popsies have 4 eyes and 5 legs. How many of each type of alien might there be if there are 38 eyes and 37 legs
Answer:
Below
Step-by-step explanation:
(3y + 2l )z + (4y + 5l) p = 38y+37 l <=======given ( y = eyes , l = legs)
z 2l + p5l = 37 l <===separating out the' l ' part
2z + 5p = 37
3y z + 4y p = 38y <====== taking out the 'y' part
3z + 4 p = 38 Solve the two underlined simultaneous equations
multiply first one by - 1.5 then add to second one to get:
-3z -7.5p = - 55.5 <===== solve for p
-3.5 p = - 17.5
p = 5 then z = 6
What is the sampling method that involves taking a random selection of people from a defined population?.
A technique called simple random sampling involves choosing a random group of individuals from a predetermined population.
What is Simple random sampling?A selection of participants from a population is chosen at random by the researcher using simple random sampling, a sort of probability sampling.
Every person in the population has the same chance of being chosen.
Then, data are gathered from as much of this randomly selected subgroup as possible.
A straightforward random sample, where each participant has an equal chance of being selected, selects a small, random portion of the entire population to represent the entire data set.
Using techniques like lotteries or random draws, researchers can generate a straightforward random sample.
Therefore, a technique called simple random sampling involves choosing a random group of individuals from a predetermined population.

Two cars leave for a vacation at the same time.
The drivers estimate how far they can travel in the first few hours.
Car B starts downtown.
Meanwhile, Car A starts 100 miles closer, heading to the same destination.
The graph shows the motion of each car.
Their speeds can be compared by comparing the steepness of the graphed line.
Use the drop-down menus to complete the statements.
Car A is travelling at a faster rate than Car B because its line on the graph is steeper.
What justifies measuring average speed?Average Understanding speed will help you better comprehend the pace of a travel. The speed may occasionally change while traveling. Finding the average speed becomes crucial in this situation so that you can get an idea of how quickly the travel will be finished.
What are typical speeds and an illustration?Divide the overall distance traveled by the time period to find the average speed. An someone traveling at an average speed of 40 miles divided by 40 minutes, or 1 mile per minute, would be driving 20 miles north and then 20 miles south to arrive at the same location (60 mph)

How to determine the output valuesFrom the question, we have the following parameters that can be used in our computation:
Rule = add -6
This means that
Output = Input - 6
Using the values in the question, we have
Output = -6 - 6 = -12
Output = 8 - 6 = 2
Output = 6 - 6 = 0

Please help me!At the beginning of spring, Jin planted a small sunflower in his backyard. The sunflower's height in inches, hh, after ww weeks, is given by the equation h=18+2.5wh=18+2.5w. What could the number 18 represent in the equation?
Answer:
The equation of the sunflower's height is h = 18+2.5w
Since the number 18 remains constant regardless of the change in number of weeks, we know that at the start h (w=0) = 18 + 2.5 x 0.
This means that, when Jin planted the sunflower, the sunflower's height was already 18 inches.
For such a reason, we can conclude that the number 18 could represent the sunflower's height at the start (original height).

Answer:
y = -1/3x + 2
Step-by-step explanation:
Slope-intercept form of a linear equation is written as:
y = mx + b, where x and y are coordinates from one of the points on the line, m is the slope, and b is the y-intercept.
1. You'll first want to find the slope, m. Slope can be calculated from two points by using the equation (y1 - y2)/(x1 - x2). If you plug your two points into this equation for x and y (making sure that y1 and x1 are from the same point and y2 and x2 are from the other), you'll get,
(3 - 1)/(-3 - 3) = 2/-6 = -1/3
m = - 1/3
2. You can then plug your slope, m, into the slope-intercept form of the equation. Using one of your points (doesn't matter which, but I'll use (3,1)), you can solve for b, your y-intercept.
1 = -1/3(3) + b
1 = -1 + b
b = 2
3. Plug the variables into the equation.
For your final equation, plug the slope, m, and y-intercept, b, that you just found.
y = -1/3x + 2

What is Expression?A mathematical expression is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.)
It is possible to compare expressions and phrases. In English, a phrase by itself could contain an action, but it doesn't constitute a full sentence.
As instances of expressions and how they connect to word phrases, consider the following:
Example: 3 + 7
The phrase "the product of three and seven"
Cost of Ticket for each student cost = $10
Cost of Ticket for each Teacher cost = $20
Let the total students be x
and, total number of teacher will be y
Total cost= 10x + 20y
As museum gives 20 % rebate for promotion
So, now total cost will be {10x + 20y} - 20/100 {10x + 20y}
So the required Expression would be 0.8{10x + 20y}.

The area of a triangle is 36 cm2. The height of the triangle is 6 cm less than the base. What is the height of the triangle?.
Answer:
[tex]\huge{\boxed{\text{The height of the triangle is 6cm.}}}[/tex]
Step-by-step explanation:
This question requires us to use a system of equations.
The area of a triangle is (1/2) * (base) * (height).
Thus, if b = base, and h = height
[tex]\frac{1}{2} bh=36[/tex]
Additionally, from the problem, we know:
[tex]b=h+6[/tex]
Then, via substitution, we can get
[tex]\frac{1}{2} *(h+6)*h=36[/tex]
Then, simplify:
[tex]\frac{1}{2} h^2+3h=36[/tex]
[tex]\frac{1}{2} h^2+3h-36=0[/tex]
[tex](\frac{1}{2} h-3)(h+12)=0[/tex]
Thus, the height must equal either 6 or -12, and because height cannot intrinsically be negative, the height must be 6.
Hope it helps :) and let me know if you want me to elaborate.

Omari buys a computer for $1,099. He

payments for the computer are $144. How
many months will it take Omari to finish
paying off the computer?
It will take 6 months for Omari to finish paying off the monthly payment for the computer.
What is the monthly payment?
The amount paid each month to repay the loan over the course of the loan is known as the monthly payment. When a loan is taken out, not only the principal, or the original lent amount, but also the interest that accrues, must be repaid.
Given, the total price of the computer = $1,099
down payment = 20% of $1,099 = $219.8
The remaining amount = $1,099 - $219.8 = $879.2
monthly payments for the computer = $144
Then, the total months to pay = 879.2/144 = 6 months
Hence, it will take 6 months for Omari to finish paying off the monthly payment for the computer.
