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
The equation and the table show the cost,y, for different sports programs as functions of the number of classes, x.
Based on the table and equation given:Gymnastics is less expensive when the classes is 1.Ice-skating is less expensive when the classes is 3 or 4.
How to Apply Equations and Tables?Given that y represents the cost, and x represents the number of classes, to complete the statements, the table is given for Gymnastics while the equation, y = 18x + 20 is given for Ice-skating program.Since the table already shows the cost for each specific number of classes for Gymnastics, find that of Ice-skating program for 1, 2, 3, and 4 classes.For 1 class, substitute x = 1 into y = 18x + 20:
y = 18(1) + 20
y = $38
For 2 class, substitute x = 2 into y = 18x + 20:
y = 18(2) + 20
y = $56
For 3 class, substitute x = 3 into y = 18x + 20:
y = 18(3) + 20
y = $74
For 4 class, substitute x = 4 into the equation y = 18x + 20:
y = 18(4) + 20
y = $92
From the above, we can conclude that, Gymnastics is less expensive when the classes is 1.
Ice-skating is less expensive when the classes is 3 or 4.

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 Equation?A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation. as in 3x + 5 Equals 15, for instance.
Equations come in a variety of forms, including linear, quadratic, cubic, etc.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation.
To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. The statement is not an equation if there is no "equal to" symbol in it.
According to our question-
M being on LN, then
LN equals LM plus MN, therefore
4x = 3 + x ( remove x from both sides ) ( subtract x from both sides )
3x Equals 3 ( divide both sides by 3 ) ( divide both sides by 3 )
x = 1
Then
LN = 3 + x = 3 + 1 = 4
Hence, LN = 4 units, the numerical length of \overline{LN}.

A jar of coins contains six times as many quarters as dimes if the totalamount of money is 28.80 how many quarters and dimes are in the jar
There are total amount of 108 quarters and 18 dimes in a jar.
What is total?Total refers to a whole or full amount, and the verb "to total" means to combine two numbers or to destroy anything. In mathematics, you add integers to get the total; the outcome is the total. The result of adding 8 and 8 is 16.
There are six times more quarters than dimes in a jar of coins.
If x represents the dimes, then the number of quarters will be 6*x if there are 28.80 in total.
A dime is worth 10 cents. In terms of money, we have 10 times as many dime.
A quarter is equal to 25 cents. We have 6 times as many quarters, which is 150 times (6 x 25).
10x +150x = 28.80
160x = 28.80
x = 0.18 that is for coins it will be 10x
10*0.18
18 dimes
similarly
6 times dimes is equal to quarters that is 6*18
108 quarters are there.

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.

Find the total cost: Alexandra bought a television set for $1105 in New York, where the sales tax rate was
8.75% of the purchase price.
The total cost of the Television is $ 1201.68.
What is Sales tax:The governments collect a consumption tax known as a sales tax on purchasing goods and services. It is always expressed as a percentage of the Purchase cost of goods and services. Here
Total cost = Purchase price + sales tax.Here we have
Alexandra bought a television set for $ 1105 in Newyork
The rate of sales tax = 8.75%
Therefore,
The total cost of Television = Cost of Television + sales tax
As we know sales tax = 8.75%
=> tax on Television = 8.75% of 1105
= [tex]\frac{8.75}{100} \times 1105[/tex]
= 0.0875 × 1105
= 96.68
The total cost of Television = 1105 + 96.68

if someone else collected a different sample from your population and measured the same variable, would they calculate the same sample statistic?
It is possible that someone else collecting a different sample from the same population and measuring the same variable would calculate the same sample statistic, but it is not guaranteed.
What is meant by Sample Statistic?Statistical measures that are derived from samples of data rather than the complete population are called sample statistics. A population parameter, such the mean or standard deviation, is estimated using this method. Depending on the type of data and the research issue being examined, sample statistics can be estimated using a variety of formulae and techniques. For instance, to get the sample mean, multiply the sum of all the observations in the sample by the total number of observations. The sample standard deviation is calculated by taking the square root of the sum of the squared differences between each observation and the sample mean. In research studies and surveys, sample statistics are frequently utilized to draw conclusions about the population.
