Which description could be written as a linear function?
a) eight more than twice a number
b) three more than the product of two numbers
c) ten more than the square of a number
d) nine more than one divided by a number
Question:
Which description could be written as a linear function?
Answer:
Option a)
Explanation:
Let 2 numbers be x1 and x2.
For the first option:
Eight more than twice a number.
The graph would be y = 8 + 2x1 which is a linear function.
For the second option:
Three more than the product of two numbers.
The graph would be y = 3 + x1x2 which is a graph function.
For the third option:
Ten more than the square of a number.
The graph would be y = 9 + (x1)² which is a graph function.
For the fourth option:
Nine more than one divided by a number.
The graph would be y = 9 + 1/x1 which is a double-parabole function.
Hopefully this answer will help you.
Answer: option a

Subtract x2 - 2x - 6 from - 6x + 5
Martin combines 8.65 liters of red paint with 8.09 liters of blue paint to make purple paint. He pours the paint equally into 4 containers and has 2.78 liters of paint leftover. How many liters of paint are in each container
Answer:
3.49 liters of paint in each container
Step-by-step explanation:
So he started off with 8.65 + 8.09 which is 16.74. Then he poured it equally into 4 containers and had 2.78 leftover. so you tak 16.74 - 2.78 which is 13.96. Lastly you divide 13.96 by 4 which is 3.49
I believe this is correct!
Answer:
3.49 liters per container
Step-by-step explanation:
First we need to find the total amount of paint
8.65+8.09=16.74(total amount of paint)
Now subtract 2.78 from 16.74 and then divide that by 4
16.74-2.78=13.96
13.96/4=3.49

A math test had 26 questions. The questions were either true/false or multiple choice. The true/false questions were worth 2 points each and the multiple choice were worth 5 points each. If the test is worth 100 points, how many of each type of question are included on the test?
Answer:
True/ false type 10 questions
Multiple choice type 16 questions
Step-by-step explanation:
Using the given formation we can make equations to solve for the number of questions of either type is to be included
let the no of true/false be =x
let the number of multiple choice to be included be = y
x + y=26 .............(1)
now making the equation of points
2x + 5y = 100 .........(2)
substitute y = 26-x from first equation in the second equation
2x + 5(26 - x ) = 100
2x - 5x + 130 = 100
3x=30
x=10
y =26-10=16
Negative 5 over 4, multiplied by x minus 5 equals negative 35. I need some help please.
Answer:

A) $2.25 for 6 bagols
B) $13.50 for 10 bagels
c) $3.30 for 6 bagols
D) $5.00 for 12 bagets
E) $8.10 for 18 bagels
Options B, C, D, and E have a unit price for bagels that is greater than the unit price Caleb pald because all their unit prices are higher then what Caleb paid.
How to calculate unit price of something?Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.
unit price of something is price of 1 thing.
LEts suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.
Given that Caleb paid $4.50 for 12 bagels.
Unit price = 4.50 / 12 = 0.375
A) $2.25 for 6 bagols
Unit price = 2.25 / 6 = 0.375
B) $13.50 for 10 bagels
Unit price = 13.50 / 10= 1.35
c) $3.30 for 6 bagols
Unit price = 3.30 / 6 = 0.55
D) $5.00 for 12 bagets
Unit price = 5.00 / 12 = 0.41
E) $8.10 for 18 bagels
Unit price = 8.10 / 18 = 0.45
Hence, Options B, C, D, and E have a unit price for bagels that is greater than the unit price Caleb pald because all their unit prices are higher then what Caleb paid.

5x + 3 = 3x + 9 what is the value of x
Answer:
x = 3
Step-by-step explanation:
5x + 3 = 3x + 9
subtract 3 on both sides (cancels out 3) (inverse operation)
5x = 3x + 6
subtract 3x on both sides (cancels out 3x) (inverse operation)
2x = 6
divide both sides by 2 (isolates x) (simplifies)

(8,_)
Answer:
(8,5)
Step-by-step explanation:
x=8,
5(8)-2y=30
40-2y=30
40-30=2y
10=2y
y=10/2
y=5
Answer:
y=5
Step-by-step explanation:
If x=8, you plug it in and the equation is 5(8)-2y=30. If you solve it further, it is 40-2y=30. If you ignore the 2y for now, 40 minus what equals 30? The answer is 10 so you look at 2y and determine how you can multiply 2 to get 10. The answer is 5 so the full equation is 40-10=30.
