Answer:
x=y-3
Step-by-step explanation:
okay, so first, we have to understand what the words mean.
PRODUCT: means the answer to a multiplication question
DECREASED: taken away or to make smaller
AND: addition or add
We can use X for "product" and Y for "a number"
now we can write it out:
x=y+5-3
OR
y+5-3=x

Answer:
148 minutes
Step-by-step explanation:
It is 3{:}32\text{ p.M.}3:32 p.M.3, colon, 32, start text, space, p, point, m, point, end text and Emma has gymnastics lessons at 6{:}00\text{ p.M.}6:00 p.M.6, colon, 00, start text, space, p, point, m, point, end text How many minutes are there until Emma's gymnastics lessons?\
The time is 3:32 pm
Emma's gymnastics lesson is at 6:00 pm
6:00 pm - 3:32 pm = 2 hours 28 minutes
That is, we have 28 minutes before 4:00 pm
And 2 hours from 4:00 pm to 6:00 pm making a total of 2 hours 28 minutes
How many minutes are there until Emma's gymnastics lessons?
Convert 2 hours 28 minutes to minutes
1 hour = 60 minutes
2 hours = 60 minutes × 2 = 120 minutes
120 minutes + 28 minutes = 148 minutes
2 hours 28 minutes to minutes = 148 minutes
Mega-Gym costs a one-time $60 membership fee and then charges $70 per month, while Mega-er-Gym does not charge a membership fee but costs $90 per month. If you sign up for Mega-Gym, how many months is it until your cost os the same as Mega-er-Gym?
Answer:
3 months
Step-by-step explanation:
So 60 dollar down and 70 per month
130 (60+70)
200
270
now 90 per month but no down
90
180
270
So 3 months
The number of months will be 3 is it until your cost is the same as Mega-er-Gym. The correct option is B.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Mega-Gym costs a one-time $60 membership fee and then charges $70 per month, while Mega-er-Gym does not charge a membership fee but costs $90 per month.
Cost of Megagym = 60 + 70m
Cost of Mega-er-Gym = 90m
90m = 60+70m
20m = 60
m = 60 / 20
m = 3 months

-6y = 4x - 24
A. X = 3, y = 2
B. X = 6, y = 0
C. Infinitely many solutions
D. No solution
Answer:
C
Step-by-step explanation:
If you rewrite the questions into linear form (y=mx+b) then you get
For the first one
2x-12= -3y
Divide by -3 and get
-2/3x +4 =y
For the second one
-6y=4x -24
Divide by -6 and get
y= -4/6x +4
Simplify the fraction and you get -2/3x+4 =y
Obviously these two lines are identical meaning that any number will work
Evaluate the expression if x=2 and y=4
4x + 3y

what is a linear function and a nonlinear fuction and how can you tell if the ordered pairs go to them
9514 1404 393
Answer:
linear: slope between any two points is the samenon-linear: slope between two points may differStep-by-step explanation:
A function is a linear function if the slope between any two ordered pairs is the same as it is between any other two. That is, the ordered pairs of a linear function will all fall on the same line when they are graphed.
__
A nonlinear function is one that is not linear. That is, its points do not all fall on the same line when graphed. Slopes between different pairs of points may differ.
_____
Detailed Example
If you are given two tables to compare, it is easiest if the x-values (inputs) are separated by a constant amount. For example, x = -2, 0, 2, 4. These all differ by 2. Then the y-values (outputs) of a linear function will all differ by the same quantity. For example, outputs 10, 15, 20, 25 for the above inputs would correspond to a linear function. This one is y = 2.5x +15.
If the output values for that same set of inputs do not have constant differences, then the function is nonlinear. For example, outputs 10, 15, 21, 27 have differences of 5, 6, 7, so correspond to a nonlinear function. This one happens to be y = (x^2 +22x +120)/8.
__
If the input values are not uniformly spaced, then you can check to see if the slope between one pair of points is the same as the slope for the next pair, and so on. The slope formula is ...
m = (y2 -y1)/(x2 -x1)
For our first table, the first pair of points (-2, 10) and (0, 15) are on a line with slope ...
m = (15 -10)/(0 -(-2)) = 5/2
Of course, when the calculations are repetitive, it is convenient to use a spreadsheet or calculator to do them. See the attachment for the calculations for this example.

Consider the first 2 terms of the sequence -6, 18,...
1. Determine the next 5 terms in the sequence if the sequence is arithmetic. Then write a function to
represent the arithmetic sequence.
2. Determine the next 5 terms in the sequence if the sequence is geometric. Then write a function to
represent the geometric sequence.
Answer:
arithmetic sequence: 24, 42, 66, 90, 114; y = 24x - 30
geometric sequence: -54, 162, -486, 1458, -4374; y = -6(-3)^(x - 1)
Step-by-step explanation:
Arithmetic sequence:
-6, 18, ...
18 - (-6) = 24
18 + 24 = 42
42 + 24 = 66
66 + 24 = 90
90 + 24 = 114
y = -6 + 24(x - 1)
y = -6 + 24x - 24
y = 24x - 30
Geometric sequence:
-6, 18, ...
18/(-6) = -3
18 * (-3) = -54
-54 * (-3) = 162
162 * (-3) = -486
-486 * (-3) = 1458
1458 * (-3) = -4374
y = -6(-3)^(x - 1)
The next 5 terms in the arithmetic sequence are 42, 66, 90, 114, 138.
What is an arithmetic sequence?An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is aₙ=a+(n-1)d.
Given that, the first 2 terms of the sequence -6, 18,....
Here, a=-6 and common difference = 18-(-6) =24
So, the next 5 terms in the arithmetic sequence are
18+24=42, 42+24=66, 66+24=90, 90+24=114, 114+24=138
42, 66, 90, 114, 138
The function is aₙ= -6+(n-1)24
= -6+24n-24
= 24n-30
The next 5 terms in the geometric sequence are
Here, a=-6 and common ratio = 18/(-6) =-3
Now, 18×(-3)=-54, -54×(-3)=162, 162×(-3)=-486, -486×(-3)=1458, 1458×(-3)=-4374
The function is [tex]a_n=-6(-3)^{n-1}[/tex]
Therefore, the next 5 terms in the arithmetic sequence are 42, 66, 90, 114, 138.

An air traffic controller is tracking two planes. To start, Plane A was at an altitude of890 meters, and Plane B was at an altitude of1322 meters. Plane A is losing altitude at 16 meters per second, and Plane B is losing altitude at25 meters per second. Expression which shows altitude of plane after x seconds.
Equation to show when they'll both be at the same altitude
Answer:
890 - 16x ; 1322 - 25x ; 9x = 432 = x = 48
Step-by-step explanation:
Plane A:
Altitude = 890 m
Altitude loss = 16 m per second
Plane A:
Altitude = 1322 m
Altitude loss = 25 m per second
Equation :
Altitude - (altitude loss * time)
Plane A:
890 - 16x
Plane B:
1322 - 25x
Plane A = Plane B
890 - 16x = 1322 - 25x
-16x + 25x = 1322 - 890
9x = 432
x = 432 / 9

Find the value of each variable. PLEASE ANSWER ASAP DUE IN 1 HOUR
Answer:
x = 36 , 2x = 72 , 3x = 108 , 4x = 144
Step-by-step explanation:
2x = P+Q (ΔABC, exterior angle property)
4x = R+S (ΔDBC, exterior angle property)
4x + 2x = P+Q+R+S = (P+R) + (Q+S) = (180 - 3x) + (180 -x) (supplementary)
6x = 360 - 4x
10x = 360
x = 36
2x = 72
3x = 108
4x = 144
check: sum of interior angles = (180 x 4) - (36+72+108+144) = 360
