The table below represents a function. Which of the following equations could be its function rule?
x y
0 -2
1 0
3 4
-2 -6
y = -2 x
y = 2 x - 2
y = x - 2
y = 3 x - 3
Answer:
[tex]y=2x-2[/tex] is the required equation.
Therefore, the second option is true.
Step-by-step explanation:
We know that the slope-intercept form of the line equation of a linear function is given by
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
Taking two points (0, -2) and (1, 0) from the table to determine the slope using the formula
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:-2\right),\:\left(x_2,\:y_2\right)=\left(1,\:0\right)[/tex]
[tex]m=\frac{0-\left(-2\right)}{1-0}[/tex]
[tex]m=2[/tex]
substituting the point (0, -2) and the slope m=2 in the slope-intercept form to determine the y-intercept i.e. 'b'.
[tex]y=mx+b[/tex]
[tex]-2 = 2(0)+b[/tex]
[tex]-2=0+b[/tex]
[tex]b=-2[/tex]
Now, substituting the values of m=2 and b=-2 in the slope-intercept form to determine the equation of a linear function
[tex]y=mx+b[/tex]
[tex]y=2x+(-2)[/tex]
[tex]y=2x-2[/tex]
Thus, [tex]y=2x-2[/tex] is the required equation.
Therefore, the second option is true.

Step-by-step explanation:
Can anybody help me on this please
Answer: -53, 53
Step-by-step explanation:
It’s asking for the slope first, so let’s find it:
First, let’s determine our coordinates.
We have (1, 930) and (6, 655).
The slope equation is [tex]\frac{y_1 - y_2}{x_1 - x_2}[/tex], so let our (1, 930) be our x_1 and y_1, and (6, 655) be our x_2 and y_2.
So, we have,
= [tex]\frac{655-930}{6-1}[/tex]
This simplifies to
= [tex]\frac{-265}{5}[/tex]
which is -53.
Therefore, the slope is -53, so the balance decrease by $53 each month.

Solve the inequality 5x – 7 > 4x + 8
Answer:
x > 15
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define inequality
5x - 7 > 4x + 8
Step 2: Solve for x
Subtract 4x on both sides: x - 7 > 8Add 7 on both sides: x > 15Here we see that any value x that is greater than 15 would work as a solution to this inequality.
Find the surface area of the square pyramid
Answer:
The surface area of the square pyramid is 40 units².
Step-by-step explanation:
As we know that the total surface area of a square pyramid can be obtained by identifying the length 'b' of its base and its slant height 's' by using the formula:
[tex]A=2bs+b^2[/tex]
From the figure, it is clear that
length of its base = 'b' = 4slant height = 's' = 3substituting the values in the formula
[tex]A=2bs+b^2[/tex]
[tex]A=2\left(4\right)\left(3\right)+\left(4\right)^2[/tex]
[tex]=2\left(4\right)\left(3\right)+16[/tex]
[tex]=40[/tex]
Therefore, the surface area of the square pyramid is 40 units².

Write an equivalent expression
-3 + 2/3y - 4 - 1/3y
Answer:
join the y-related together and the others together
ie -7+1/3y
thats the shortest form one can drill down to, so that should be the answer
Step-by-step explanation:
To write an equivalent expression, we need to simplify the given expression by combining like terms. Like terms are terms that have the same variable and exponent. We can use the distributive property to remove parentheses or other grouping signs to then combine like terms.
The given expression is -3 + 2/3y - 4 - 1/3y. We can see that there are no parentheses or grouping signs, so we can skip that step. We can also see that there are two like terms: 2/3y and -1/3y. We can combine them by adding their coefficients: 2/3 + (-1/3) = 1/3. So, we get:
-3 + 2/3y - 4 - 1/3y = -3 - 4 + (2/3 - 1/3)y = -7 + (1/3)y
This is the simplified expression that is equivalent to the given expression.

what is what3 2/3 + 3/5 as a fraction brainly
Answer:
It is 4 4/15
Step-by-step explanation:
We convert 2/3 and 3/5 to fifteenths because we cant add numbers with different denominators.
2/3 = 10/15 | 3/5 = 9/15
10/15 + 9/15 = 19/15 = 1 4/15. Then, we add the 3.
3 + 1 4/15 = 4 4/15.
What is the value of x?
A.22
B.38
C.42
D.5
Answer: B) 38
Step-by-step explanation:
1) [tex]x+(x+6)+(3x-16)=180[/tex] (sum of angles in triangle)
2) [tex]5x-10=180[/tex] (Algebra)
3) [tex]5x=190[/tex]
4) x= 38 degrees
Answer: x = 38
Step-by-step explanation:
1) Add 3x - 16 and x + 6 and x together. You get 5x - 10.
2) All sides of a triangle equals 180 degrees, so that means 5x - 10 = 180.
3) Add 10 to both sides, 5x = 190.
4) 190/5 = 38
5) 38 is your answer.

Can someone please help me, I really need it
Answer:
∠EGA = 123°
∠EHD = 57°
Step-by-step explanation:
Determine the measure of ∠EGA:
Since ∠EGB and ∠EGA make up the angle of a straight line (180°):
∠EGB+∠EGA = 180
57+∠EGA = 180 (given that ∠EGB = 57°)
∠EGA = 123°
Determine the measure of ∠EHD:
∠EHD = ∠EGB (corresponding angles of parallel lines are equal)
∠EHD = 57° (given that ∠EGB = 57°)

Susan buys the items listed below at a grocery store. 2 packages of chicken priced at $12.56 per package 1 pound of broccoli priced at $1.98 per pound 2 1 gallon of milk priced at per $3.49 gallon There is no sales tax on the food she buys. Susan pays for the items and receives $0.80 in change. What amount of money does Susan use to pay for the items?
Answer: $30
Step-by-step explanation:
Your question isn't well written. Here's the complete question:
Susan buys the item listed below at a grocery store. 2 packages of chicken priced at $12.36 per package. 1/2 pound of broccoli priced at $1.98 per pound. 1gallon of milk priced at $3.49 per gallon. There is no sales tax on the food she buys. Susan pays for the items and recevies $0.80 in change. What amount of money does Susan use to pay for the items?
2 packages of chicken priced at $12.36 per package will cost:
= 2 × $12.36
= $24.72
1/2 pound of broccoli priced at $1.98 per pound will cost:
= 1/2 × $1.98
= $0.99
1 gallon of milk priced at per $3.49 per gallon will be:
= 1 × $3.49
= $3.49
We are then told that Susan pays for the items and receives $0.80 in change. The amount of money does Susan use to pay for the item will be:
= $24.72 + $0.99 + $3.49 + $0.80
= $30

Simplify the expression: 18.1 - 1.1(7.4 - 9.6 + 0.5) please show your work!
Answer:
19.97
Step-by-step explanation:
18.1 - 1.1 x (7.4 - 9.6 + 0.5)
18.1 - 1.1 x (-2.2 + 0.5)
18.1 - 1.1 x (-1.7)
18.1 + (1.87)
19.97
The simplified value of the expression 18.1 - 1.1(7.4 - 9.6 + 0.5) is 36.8.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, An expression 18.1 - 1.1(7.4 - 9.6 + 0.5).
let us multiply each term of the expression to remove the decimal.
∴ 181 - 11(74 - 96 + 5).
= 181 - 11(-17).
= 181 + 187.
= 368 but the actual answer is 36.8 as we have to divide by 10.
