What if Jacob decided to buy a used game system and 5
games? Then what would the cost be for his purchase?
Remember: Jacob is buying a used game system for
$120 from a store. The store also sells used games for
$12 each.
Answer:It would be 180 dollars
Step-by-step explanation:
because 12X5=60 and 120+60=180 which is your total for selling the game system
Answer:
The cost of his purchase would be $180
Step-by-step explanation:
You would multiply the 5 games he wants to buy by the price of the games to get 60 and then add that to the price of the gaming system.

A class of x students are going on a treasure hunt and need to be separated into four groups. Which expression could be used to determine the total number of students in each group?
Answer:
X/4
Step-by-step explanation:
The number of students (X) would have to be divided by 4 (the number of groups), meaning the number of students in each group must be:
the total number of students (X)÷ the number of groups (4)

Determine the unknown angle measure 8th grade
9514 1404 393
Answer:
a. m∠C = 44°
b. m∠P = 60°
Step-by-step explanation:
In each case, the missing angle brings the sum of angles to 180°. So, its value is the difference between 180° and the sum of the given angles.
a. m∠C = 180° -90° -46°
m∠C = 44°
__
b. m∠P = 180° -110° -10°
m∠P = 60°
What is the length of said JL
Answer:
13
Step-by-step explanation:
pythagorean theorem: a^2 + b^2 = c^2
5^2 + 12^2 = c^2
169=c^2
13=c
it's also special right triangle 5-12-13 (it's just something u remember)
Answer:
JL = 13
Step-by-step explanation:
a² + b² = c²
5² + 12² = c²
25 + 144 = c²
169 = c²
√169 = c
13 = c
JL = 13

The function f (x) = x2 with a vertical stretch of 8.5, a translation left 4 units and a translation 2 units down. Write the function g(x) that represents the transformations.
Answer:
g(x)=8.5([tex]x^{2}[/tex]+4)
Step-by-step explanation:
vertical stretch means to put that number in front like this:
8.5(x^2)
Then 4 units to the left means it will look like this. (Translation to the left is plus in the parentheses and for the right it's negative in the parentheses.)
8.5(x^2+4)
So you full equation is:
g(x)=8.5(x^2+4)
x - 4y = -1
3x + 5y = 31

Answer:
(x, y) = (7, 2)
Step-by-step explanation:
We assume you want the solution to this system of equations.
Since you're seeking help from "technology", it is appropriate to use the technology of a graphing calculator to find the solution. The attachment shows it to be (x, y) = (7, 2).
__
The coefficient of x in the first equation is 1, so it is convenient to use that equation to write an expression for x:
x = 4y -1 . . . . . add 4y to the equation
3(4y -1) +5y = 31 . . . . substitute for x in the second equation.
17y = 34 . . . . . . . . . . . simplify, add 3
y = 2 . . . . . . . . divide by 17
x = 4(2) -1 = 7 . . . . use the equation above to find x
The solution is (x, y) = (7, 2).

Answer:
40
Step-by-step explanation:
The angle marked x is an exterior angle of the polygon.
The sum of the measures of the exterior angles of a polygon, one exterior angle per vertex, is 360 deg.
In a regular polygon, all exterior angles are congruent. The number of exterior angles, one per vertex, is the same as the number of sides.
We count the number of sides of this polygon and see it has 9 sides.
Since it is a regular polygon, he measure of each exterior angle is 360 divided by the number of sides.
x = 360 deg/9 = 40 deg
Answer:
40 hope this helps

Given the function h(x) = 4x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3. Part A: Find the average rate of change of each section. (4 points) Part B: How many times greater is the average rate of change of Section B than Section A? Explain why one rate of change is greater than the other. (6 points) (10 points)
Answer:
Part A. 4/1 ( 4 over 1 ) and -4
Part B. it is -1 times greater. It is -1 times greater because the values are higher.
Step-by-step explanation:
Average rate of change formula is change in f(x) values over corresponding change in x values
Part A.
first make a table.
X - 0, 1
f(x) - 0, 4
To figure out the y f(x) values you plug the first x value into x in the function h(x)=4x like h(x)=4(0) and you get 0...and plug in the next x value into the function h(x)=4x like h(x)=4(1) and you get 4.
You now have the coordinates (0,0) and (1,4) and now to find the average rate of change you put 4 - 0 / 1 - 0 ( 4 - 0 over 1 - 0) and solve so 4-0=4 and 1-0=1 the average rate of change for this is 4/1.
For B you do the same thing.
