given the equation -2x + 3y = 12, find the missing value in the ordered pair (-3,_)
please hurry y'all
Answers
Answer: y = 3
Step-by-step explanation: You're given x, find y.
-2(-3) + 3y = 12 (substitute in for x)6 + 3y = 12 (multiply)3y = 9 (divide both sides by 3)3 = yThe solution is P ( -3 , 2 )
The value of y from the equation -2x + 3y = 12 is y = 2
What is an Equation?
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.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
-2x + 3y = 12 be equation (1)
The point on the line is P = P ( -3 , y )
On simplifying the equation , we get
Substituting the value of x = -3 in the equation , we get
-2x + 3y = 12
-2 ( -3 ) + 3y = 12
6 + 3y = 12
Subtracting 6 on both sides of the equation , we get
3y = 6
Divide by 3 on both sides of the equation , we get
y = 2
Therefore , the value of y is 2
Hence , the point P ( -3 , 2 ) lies on the equation -2x + 3y = 12

A company that manufactures radios first pays a start-up cost, and then spends a certain amount of money to manufacture each radio. If the cost of manufacturing rr radios is given by the function c(r)=5.25r+125c(r)=5.25r+125, then the value of 125125 best represents
A. The start-up cost.
B. The amount spent to manufacture each radio.
C. The profit earned from the sale of one radio.
D. The average number of radios manufactured.
Answers
Answer: b
Step-by-step explanation:
The correct statment is the amount spent to manufacture each radio.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We have given that the cost of manufacturing the radios is;
c(r) = 5.25r + 125
where, r is the number of radios
This is a linear function and the general form of a linear function as;
f(x) = mx + b
Here m represents the slope of the function or the rate of change of the function while b represents the intercept of the initial value of the function.
From the given function we have;
m = 5.25
b = 125
Which means that 5.25 represents the rate of change of the function. It mean the value by which the value of r changes the function.
In other words,the correct statment is the amount spent to manufacture each radio.

What is Arithmetic Sequence?An arithmetic progression (AP) can be defined in one of two ways:
A series in which the differences between each pair of following terms are the same is known as an arithmetic progression.An arithmetic progression is a sequence in which every phrase—aside from the initial term—is created by multiplying the previous term by a predetermined amount.Given:
-33, -24, -15, -6, ...
first term,
a=-33
d= -24 + 33 = 9
so, [tex]a_5[/tex] = a+ 4d
= -33 +4(9)
= 3
[tex]a_6[/tex] = a+ 5d
= -33 +5(9)

Which of these functions had a greater rate of change than the function graphed below, and why?
Answers
Answer:
C
Step-by-step explanation:
When we talk of rate of change, we talk of the slope of the line
If we had a line;
y = mx + b
m is the slope ( which is the rate of change)
To get the slope of the line, we select any two points on the line and apply the slope formula
m = y2-y1/x2-x1
let us take points (0,0) and (3,9)
m = 9-0/3-0 = 9/3 = 3
The slope here is 3
so from the option, we can see that the third option is the correct answer
A bus traveled 336 miles in 7 hours. It traveled the same number miles each hour. If the bus continues at the same numder of miles per hour, how many miles will the travel in 15 hours? Explain.
Answers
Answer:
The bus will travel 720 miles in 15 hours.
Step-by-step explanation:
As you know that the bus traveled 336 miles in 7 hours and it traveled the same number miles each hour, you can divide the amount of miles it traveled by the number of hours to determine the amount of miles per hour:
336/7=48
Now, you can multiply the number of miles the bus traveled each hour for 15 hours:
48*15=720
According to this, the answer is that the bus will travel 720 miles in 15 hours.

Landing on 2 = 30
Landing on 3 = 19
Landing on 4 = 25
Landing on 5 = 29
Landing on 6 = 17
The experimental probability of landing in a two:
Experimental probability :
Number of times event occurs / Number of trials
Number of 2 landings = 30
Experimental probability of landing in a 2 ;
30 / 120 = 1/4

The engineer will collect data to perform a hypothesis test on the proportion of all households without power. Which of the following are the appropriate hypotheses for such a test?
Answers
Answer:
D
Step-by-step explanation:
The null hypothesis is that p=0.19. The engineer says that this estimate is too low, meaning he believes the true proportion is greater than 0.19 - p>0.19. Because this is a proportion of ALL houses in the state, we use p rather than phat, leaving D as the correct answer.

(HELP PLEASE I BEG)The amount of money that Maria had in a savings account at the beginning of 2018 was $2,750. At the beginning of 2019, the same savings account now had $3,201 in it.
By what percent did Maria’s savings increase from 2018 to 2019? Show the work that leads to your answer and do not round.
Answers
Step-by-step explanation:
First, you need to find the difference 3201-2750=451, it has increased by 451, then divide the difference by the original number, which is 2750 because thats what she started off with (3201 would be the new number)
Increase% = Increase ÷ Original Number ×100
451÷2750×100=16.4%
The percent of Maria’s savings increase from 2018 to 2019 will be 16.4%.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
The amount of money that Maria had in a savings account at the beginning of 2018 was $2,750.
And, At the beginning of 2019, the same savings account now had $3,201 in it.
Now,
The increased amount = $3,201 - $2,750
= $451
So, The percent of Maria’s savings increase from 2018 to 2019 is,
⇒ Increased percent = 451/2750 × 100
= 16.4%
Thus, The percent of Maria’s savings increase from 2018 to 2019 = 16.4%.
