let f (x) = 4x-9. write a function g whose graph is a translation 1 unit right of the graph of f
Function g(x) = 4x -13 after the graph is translated 1 unit right of the graph of f(x) = 4x - 9.
As given in the question,
Function f(x) = 4x -9
Graph g(x) get translated 1 unit right of the graph of function f(x)
It means change in the value of x equals to x-1
g(x) = 4(x-1) -9
⇒ g(x) = 4x -4 -9
⇒ g(x) = 4x-13
Therefore, function g(x) = 4x -13 after the graph is translated 1 unit right of the graph of f(x) = 4x - 9.

Kiara and Donovon attend different middle schools. They both went to their schools’ winter carnivals. Kiara paid a $5 entrance fee and bought several tickets costing $0.75 each for games and rides. Donovon paid a $7 entrance fee and bought several tickets costing $0.50 each for games and rides. How many tickets, , must Kiara and Donovan each buy in order for the cost of attending their school carnivals to be the same?
Using linear functions, it is found that they have to buy 8 tickets for the costs to be the same.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For the functions in this problem, we consider that:
The entrance fee is the intercept.The cost for carnivals(games/rides) is the slope.Hence the cost functions for Kiara and Donovon are given, respectively, by:
K(x) = 5 + 0.75x.D(x) = 7 + 0.5x.The costs will be the same when:
K(x) = D(x)
5 + 0.75x = 7 + 0.5x.
0.25x = 2
x = 2/0.25
x = 8.
They have to buy 8 tickets for the costs to be the same.

if DF = 9x-39 find EF
DE = 47
EF = 3X+10
The length of the line segment EF is 106.
The distance between the end points of DF is equal to 9x-39.The distance between the end points of DE is equal to 47.The distance between the end points of EF is 3x + 10.Applying the logic that the line segments are a part of the same straight line, we can conclude thatThe length of the line segment DF is equal to the sum of the lengths of the line segments DE and EF.DF = DE + EF.9x - 39 = 47 + (3x + 10)9x - 6x = 47 + 10 + 393x = 96x = 32The length of the line segment EF is 3*32 + 10.The length of the line segment EF is 96 + 10.Thus, the length of the line segment EF is 106.To learn more about distance, visit :

A large jar contains an unknown number of red gumballs and 145 green gumballs. As part of a seventh-grade class project the teacher asks Carlos to estimate the total number of gumballs in the jar using a sample. Carlos draws a sample of 55 gumballs, of which 11 are red and 44 are green. Use Carlos' sample to estimate the number of gumballs in the jar.
The total number of gumballs in the jar calculated using probability is about 181.
Probability is the study of chance. The likelihood of an event to occur given as a fraction is probability.
For a sure event the probability is 1 and for an impossible event the probability is 0.
Carlos draws a sample of 55 gumballs. Out of which the number of green gumballs is 44.
Probability of a green gumball= number of green gumballs ÷ total number of gumballs
P(green) = 44 ÷ 55 = 4/5
Now in the sample the number of green gumballs is 4/5 , and in the jar the number of green gumballs is 145 .
Let us consider there are x gumballs in total in the jar.
P(green)=145 ÷ x
We know that P(green)= 4/5
∴4/5 = 145 ÷ x
or, x = 145 × 5 ÷ 4
or, x = 181.25 gumballs.
or, x ≈ 181 gumballs(As the number of gumballs cannot be a fraction)
Therefore there are about 181 gumballs in total .

A 75% antifreeze solution is to be mixed with a 90% antifreeze solution to get 360 liters of a 85% solution. How many liters
of the 75% and how many liters of the 90% solutions will be used?
In linear equation , 240 liters of 90% solutions will be used.
What are a definition and an example of a linear equation?
A linear equation with one variable is one that contains just one variable. It has the formula Ax + B = 0, with A and B being any two real numbers and x being an ambiguous variable with only one possible value. One such linear equation in one variable is 9x + 78 = 18.Let x be the quantity of 75% antifreeze solution and y be the quantity of 90% antifreeze solution,
Since, the total quantity of the mixture = 360,
⇒ x + y = 360 ----- (1),
Also, the resultant solution is of 85% antifreeze solution,
⇒ 75 % of x + 90% of y = 85% of 360
0.75x + 0.90y = 0.85 × 360
0.75x + 0.90y = 306
75x + 90y = 30600 -----(2),
Equation (2) - 75 × equation (1),
We get,
15y = 3600
⇒ y = 240
Hence, 240 liters of 90% solutions will be used.

She should buy five sweaters.
She should buy five sweaters?A rational consumer would purchase a good as long as marginal benefit is equal or greater than marginal cost.
Marginal cost is the additional cost generated by producing an additional unit of output. Marginal benefit is the benefit derived from consuming one extra unit of a good.

Eli runs a distance of 3 miles in 2/5 of an hour. jess runs a distance of 4/5 mile in 1/10 of an hour. who had the faster speed
Jess had a faster speed of 8 miles/hour
Given:
3 miles in 2/5 hour
4/5 miles in 1/10 hour
To find the quotient, we must switch to the inverse approach,
where 2/5 becomes 5/2 and 1/10 becomes 10/1.
For Eli:
A distance of 3 miles is covered in 2/5 of an hour.
3 miles equals 2/5*1
3 miles equals 2/5 hour
The inverse amount is multiplied as
3*5/2 miles = 1 hour.
7.5 miles
Eli moves at a 7.5 mph speed.
For Jess:
1/10 of a mile is covered in 4/5miles.
1/10 * 1 hour times 4/5 miles
1/10 hour equals 4/5 miles.
The inverse number is multiplied as follows: 4/5 * 10/1 = 1 hour.
40 miles at a speed of 5 miles per hour.
1 hour Equals 8 miles
Jess's speed is 8 miles per hour.
Hence, Jess had a faster speed of 8 miles per hour

Decide what values of the variable cannot possibly be solutions for the equation. Do not solve.
By inspecting the denominator, the values of x cannot be solutions of the rational equation are x₁ = - 3 and x₂ = 2.
What values does lead to an indetermination in a rational equation?
A rational equation is an expression of the P(x) / Q(x), where P(x) and Q(x) are the equations of the numerator and the denominator functions. The rational equation becomes undefined for all x-values such that Q(x) = 0. Then, we must look up for all values of x such that:
x² + x - 6 = 0
x² + [3 + (- 2)] · x - 6 = 0
x² - 2 · x + 3 · x - 6 = 0
x · (x - 2) + 3 · (x - 2) = 0
(x + 3) · (x - 2) = 0
x₁ = - 3 ∨ x₂ = 2
The values of x cannot be solutions of the rational equation are x₁ = - 3 and x₂ = 2.

Answer:
[tex](x-2)^2+(y+2)^2=14[/tex]
Step-by-step explanation:
Equation of a circle
[tex](x-a)^2+(y-b)^2=r^2[/tex]
where:
(a, b) is the center of the circle.r is the radius of the circle.Given equation:
[tex](x-7)^2+(y-7)^2=7[/tex]
Therefore:
center = (7, 7)radius = √7Area of a circle
[tex]\sf A=\pi r^2[/tex]
where:
r is the radius.Therefore, the area of a circle with radius √7 is:
[tex]\implies \sf Area=\pi \left(\sqrt{7}\right)^2=7 \pi\:\:square\:units[/tex]
Therefore, a circle with twice the area would be:
[tex]\implies \sf Area = 2 \cdot 7 \pi = 14 \pi \:\: square\:units[/tex]
Therefore, its radius would be:
[tex]\begin{aligned}\implies \sf \pi r^2 & = \sf14 \pi\\\sf r^2 & = \sf 14\\\sf r & = \sf \sqrt{14}\end{aligned}[/tex]
So the equation of a circle with a center at (2, -2) and a radius of √14 is:
[tex]\implies (x-2)^2+(y-(-2))^2=\left(\sqrt{14}\right)^2[/tex]
[tex]\implies (x-2)^2+(y+2)^2=14[/tex]

The monthly cost (in dollars) of a long-distance phone plan is a linear function of the total calling time (in minutes). The monthly cost for 53 minutes of calls is $12.03 and the monthly cost for 65 minutes is $13.59. What is the monthly cost for 57 minutes of calls?
The monthly cost of 57 minutes calls is $12.55.
The monthly cost is $12.03 for 53 minutes and $ 13.59 for 65 minutes call
Therefore we have two points (53, 12.03) and ( 65, 13.59)
slope = (13.59 - 12.03)/ ( 65 - 53)
= 1.56/ 12
= 0.13
The intercept is
y = mx + c
12.03 = 0.13×53 + c
12.03 = 6.89 + c
c = 5.14
Equation:
cost = 0.13(minutes) + 5.14
= 0.13×57 + 5.14
= 7.41 + 5.14
= 12.55
Therefore the monthly cost for 57 minutes is $12.55.
