Answer:
No, because some relations are not functions. Relations are equations that begin with x=, and let's say x=5.
This is not a function because if you graph this line, it is vertical, and functions can't share the same x coordinate point (input) with other y coordinate points (output). There must be one output for every input, meaning that this relation is not a function.
Step-by-step explanation:
Evaluate (x *3 − 15) − (y + 6) for x = 4 and y = 1.

2.) 31
3.) 42

Brendan uses his phone primarily to take a lot of selfies. The storage space on his phone is limited, so Brendan needs to keep track of how many selfies he takes.
There is a proportional relationship between the number of selfies Brendan takes, x, and the amount of storage (in megabytes) he uses taking selfies, y. Write an equation for the relationship between x and y. Simplify any fractions.

The sum of 5.5 and twice a number is -10
What is the number?
n = 7.75
n=2.125
n= -7.75
n=-2.125
Answer:
n=-7.75
Step-by-step explanation:
Based on the given conditions, formulate: 5.5+2×X=-10
Rearrange unknown terms to the left side of the equation:2x=-10-5.5
Calculate the sum or difference:2x=-15.5
Divide both sides of the equation by the coefficient of variable:x=-15.5/2
Multiply both the numerator and denominator with the same integer:-155/20
Cross out the common factor:-31/4
get the result: -7.75
Answer: -7.75

Answer:
yes
Step-by-step explanation:
7 weeks * 7 days per week = 49 days49 days * 2 meals per day = 98 total meals98 meals * 31 grams per meal = 3038 grams after 7 weeksAnswer: Yes, he will meet his goal of eating 3,000 grams of protein in 7 weeks.
Step-by-step explanation: So for the top part your answer is supposed to be 4400.2 grams of protein in 7 weeks. You can get that by adding up the grams of protein for each type of food on the chart. Then you multiply that by 2 to get the amount they will be eating for 1 day which is 89.8. After that, because you have to solve for how much they will be eating for 7 weeks, you will have to multiply 89.9 x 49(days in total). To get you to the answer 4400.2. Now you have your answer for the second part of the problem. Yes, he will meet his goal of eating 3,000 grams of protein in 7 weeks.

Answer:
x = 20
Step-by-step explanation:
2x + 2x + 10 = 90
4x + 10 = 90
4x = 80
x = 20
Answer:
Angle AOB is made up of angle AOC and COB.
AOC + COB = AOB
Since AOB is a right angle, it is 90°.
Using the values given, AOC = [tex]2x[/tex] and COB = [tex]2x+10[/tex].
Therefore,
[tex]2x+2x+10=90[/tex]
Subtract 10 from both sides:
[tex]2x+2x+10-10=90-10[/tex]
[tex]2x+2x=80[/tex]
[tex]4x=80[/tex]
Divide both sides by 4:
[tex]\frac{4x}{4} =\frac{80}{4}[/tex]
[tex]x=20[/tex]

The price of a television was reduced from $400 to $300. By what percentage was the price of the television reduced?
Answer:
25%
Step-by-step explanation:
Think of quarters, there's 4. They're all 25 cents. Take away one and you have 75%. It was a 25% reduction
Answer:
25%
Step-by-step explanation:
The $400 that you start with could be divided by 4, and you would have $100. That is dividing by 75%, 3/4 of the total money. Therefore, you can remove 1/4 of the $400 to get the $300. That is reduction by, 25%.

3x + 5y + 10
5x - 3y = -6
Answer:
3x + 5y + 10= 3
5x - 3y = -6
Step-by-step explanation:
1. m=-3/5
2. Simplifying
5x + -3y = 6
Solving
5x + -3y = 6
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
5x + -3y + 3y = 6 + 3y
Combine like terms: -3y + 3y = 0
5x + 0 = 6 + 3y
5x = 6 + 3y
Divide each side by '5'.
x = 1.2 + 0.6y
Simplifying
x = 1.2 + 0.6y

Evaluate the expression for the given values.
8x+2yz, where x=12, y = 4, and z = 2
Answer:
112
Step-by-step explanation:
8x+2yz is our starting equation
8(12)+2(4)(2) I then substitute the variables for their numbers
96+2(4)(2) I then multiply 8x12, which equals 96.
96+8(2) I now multiply 2x4, which is 8.
96+16 I finally multiply 8x2 which is 16
112 Lastly I then add 96+16 which equals 112.

Select all the equations that have {4} as its solution set. 5 + 2x = 3x + 37−x=12x79−3x=12x+19x2+3=10x−21
5 + 2x = 3x + 3
7−x=12x
79−3x=12x+19
x2+3=10x−21
Answer:
Option 3 (79−3x=12x+19)
Step-by-step explanation:
When replacing x with 4 you will get the answer 67 = 67, which is true! The other three options are not true when replacing x with 4.
Equations 79-3x=12x+19 and x²+3=10x−21 has the solution set {4}.
Given that, the equations that have {4} as its solution set.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
1) Solution of an equation 5 + 2x = 3x + 3 is
3x-2x=5-3
⇒x=2
2) Solution of an equation 7−x=12x is
7−x=12x
⇒12x+x=7
⇒13x=7
⇒x=7/13
3) Solution of an equation 79−3x=12x+19 is
12x+3x=79-19
⇒15x=60
⇒x=4
4) Solution of an equation x²+3=10x−21 is
x²+3=10x−21
⇒ x²-10x+24=0
⇒ x²-6x-4x+24=0
⇒ x(x-6)-4(x-6)=0
⇒ (x-6)(x-4)=0
⇒ x=6 or 4
Therefore, equations 79-3x=12x+19 and x²+3=10x−21 has the solution set {4}.
