Answer:
x = 7
Step-by-step explanation:
Given s(x) = - 3(x - [tex]\frac{2}{3}[/tex]) + 19 and s(x) = 0, then equate the right sides, that is
- 3(x - [tex]\frac{2}{3}[/tex] ) + 19 = 0 ( add 19 to both sides )
- 3(x - [tex]\frac{2}{3}[/tex] ) = - 19 ← distribute the parenthesis
- 3x + 2 = - 19 ( subtract 2 from both sides )
- 3x = - 21 ( divide both sides by - 3 )
x = 7
-2 (x + 1/4) + 1 = 5 solve for x

1. Rakesha claims that the equation f(n) 5 5n 2 7 is the function notation for the sequence that is
represented by the explicit formula an 5 22 1 5(n 2 1). James doesn’t understand how this can be
the case.
a. Help James by listing the steps to write the explicit formula of the given sequence in function
notation. Provide a rationale for each step.
b. Graph the function. Label the fi rst 5 values of the sequence on the graph.
2. Determine whether each table of values represents a linear function. For those that represent
linear functions, write the function. For those that do not, explain why not.

I do not know which formula to use
Carla bought a dress at a sale for 20% off the original price. The sale price of the dress was $68.90. Find the original price of the drees, in dollars.
Step by step explanation please.
Answer:
I think it's the second formula.
Step-by-step explanation:
Let x be the original price.
The discount rate is 20%
Sale Price is $68.90
Discount = 20% of x = 0.2x
Using the formula, Sale Price = Original Price - Discount,
Original Price - Discount is x-0.2x = 0.8x
$68.90 = 0.8x
From here on, just do the equation :) Hope this helps!

EASY 10 POINTS QUESTION 7 PLEASEEEEEEE
Answer:
x=9
Step-by-step explanation:
-2x+9=-4x+27
first you want to get the -4x on the other side of the equal sign you do that by -4- -4 which will cancel them out and you do -2 - -4 = 2x
now you have 2x+9=27 now you do 9-9 which will cancel them out and you do 27 - 9 = 18
Now you have 2x=18 then you want to divide 2 by 2x which will cancel out the 2 and you want to divide 2 by 18 which equals 9 so you answer is x=9
hope this helps

Question 5 please. I need help with thus.
Answer:
TU = 63.84 in
Step-by-step explanation:
Since T lies on RU, then
RT + TU = RU, substitute values
9x - 2.64 + 11x - 4.36 = 117, that is
20x - 7 = 117 ( add 7 to both sides )
20x = 124 ( divide both sides by 20 )
x = 6.2
Thus
TU = 11x - 4.36 = 11(6.2) - 4.36 = 68.2 - 4.36 = 63.84 in

Step-by-step explanation:
line I is the perpendicular bisector of MN. find m
Answer:
m = 68
Step-by-step explanation:
MN bisects it or splits it in half so we know N = M, which we could also write as 8x-12 = 5x+18 because they give us those equations
once you have 8x-12 = 5x+18 you can subtract 5x from both sides, so you will get 3x-12 = 18, then you can add 12 to both sides and you will get 3x = 30. Once you have narrowed down to this you can divide three by both sides making x = 10
Now that we know x =10 we can insert it into the equation
5(10) + 18 = m
50 + 18 = m
m = 68

Step-by-step explanation:
A jetliner uses 3,600 gallons of fuel per hour while it is cruising, and there are 15,000 gallons of fuel in the jetliner's fuel tank when it begins to cruise. If y represents the amount of fuel, in thousands of gallons, remaining in the fuel tank after the jetliner cruises for x hours, determine the graph of the solution set for this situation and the equation modeled by the graph.
Answer:
y = 15 - 3.6x.
Step-by-step explanation:
The initial amount of fuel before cruising begins = 15,000 gallons.
The equation is y = 15 - 3.6x where y is in thousands of gallons and x = number of hours.
Which of the following is equivalent to 5x-6y=20?
A y=5/6x
B y=5/6x-10/3
C y=6/5x+4
D y=-5/6x
Answer:
y = [tex]\frac{5}{6}[/tex]x - [tex]\frac{10}{3}[/tex]
Step-by-step explanation:
Given expression:
5x - 6y = 20
To solve this problem, we make y the subject of the expression:
Solution
5x - 6y = 20
Add -5x to both sides of the expression;
-5x + 5x - 6y = 20 + (-5x)
-6y = 20 - 5x
Now, multiply both sides by [tex]-\frac{1}{6}[/tex] ;
[tex]-\frac{1}{6}[/tex] x (-6y) = [tex]-\frac{1}{6}[/tex] (20 - 5x )
y = [tex]-\frac{20}{6}[/tex] + [tex]\frac{5}{6}[/tex]x
y = [tex]\frac{5}{6}[/tex]x - [tex]\frac{10}{3}[/tex]
During an investigation on speed, a ball rolls down a ramp a distance of 8 m in a time of 2 seconds. What is the average speed of the ball in m/s?
Answer:
4 m/s
Step-by-step explanation:
To find the average speed of the ball, divide the number of meters by the number of seconds:
8/2
= 4
So, the average speed of the ball is 4 m/s
Rosie works as a riveter and earns $20.50 per hour for a base 40-hour week. If she works overtime, she earns time-and-a-half, that is, 1.5 times her base rate of pay up to 10 more hours of overtime, and then double-time, that is, twice her base rate beyond that. One particularly busy season, Rosie worked 53 hours per week for 10 weeks. What did Rosie earn that season? (Do NOT include punctuation in your answer.)

is a relation that is also a function.
{(1,6), (1,7), (7, 8), (8, 9)}
{(2,3), (3, 2), (2, 4), (4, 2)}
{(0, 1), (0, 2), (0, 3), (0,4)}
|{(1, 1), (3, 2), (6,3), (8,4)}
Answer:
The relation {(1, 1), (3, 2), (6,3), (8,4)} is also a function ⇒ D
Step-by-step explanation:
The relation formed from a set of ordered pairs could be a function if every x-coordinate has only one y-coordinate corresponding to it
Examples:
The relation {(1, 3), (-2, 5), (1, -2)} is not a function because x = 1 has two values of y 3 and -2The relation {(2, -3), (-2, 0), (1, 5)} is a function because x = 2 has only y = -3, x = -2 has only y = 0, and x = 1 has only y = 5Let us check all the relation to find which one is a function
∵ The relation is {(1, 6), (1, 7), (7, 8), (8, 9)}
∵ At x = 1, y = 6 and 7
→ x has two values of y
∴ The relation is not a function
∵ The relation is {(2, 3), (3, 2), (2, 4), (4, 2)}
∵ At x = 2, y = 3 and 4
→ x has two values of y
∴ The relation is not a function
∵ The relation is {(0, 1), (0, 2), (0, 3), (0,4)}
∵ At x = 0, y = 1, 2, 3, and 4
→ x has four values of y
∴ The relation is not a function
∵ The relation is {(1, 1), (3, 2), (6,3), (8,4)}
∵ At x = 1, y = 1
∵ At x = 3, y = 2
∵ At x = 6, y = 3
∵ At x = 8, y = 4
→ Every x has only one value of y
∴ The relation is a function
∴The relation {(1, 1), (3, 2), (6,3), (8,4)} is a function
