Joe took $12 to the arcade. Each game cost $.50 to play. This situation can be modeled with the equation y + -.50 x+ 12. This represents the relationship between money Joe has remaining, y, and the number of games he plays, x. Use the function to determine the x-intercept.
State the Domain and Range for this equation in the context of the problem scenario?
Answer:
x-intercept: x=24
DOMAIN: (0,24) where x∈Natural Numbers
RANGE: (0,12) where y∈Natural Numbers
Step-by-step explanation:
Remain money = y
Number of games = x
Given function:
[tex]y=12-0.5x\\[/tex]
x-intercept:x-intecept is the value of x where y becomes zero.
Substitute y=0 in the given equation:
[tex]0=12-0.5x\\0.5x=12\\x=\frac{12}{0.5}\\x=24[/tex]
Domain:Domain is a set of all possible values of x.
x= No. of games (So x cannot be negative)
y= Remain Amount (So y cannot be negative)
So the minimum value of x is 0 because x cannot be negative.
Maximum value of x is the value for which y doesn't become negative. For any value of x>24, y <0 which is not possible.
So maximum value of x is 24
DOMAIN: (0,24) where x∈Natural Numbers
Range:
Range is a set of all outcomes of y for all possible values of x.
For x=0 , y =12
for x=24 , y = 0
So
RANGE: (0,12) where y∈Natural Numbers
help please i did a problem like this and got it wrong i honestly think im confusing the closed and open dots. can some one just please help
Answer:
It should be a "closed" dot facing the left side (towards the negative numbers)
Step-by-step explanation:
The graph will be a line segment with endpoints -1 and 1. Both endpoints are closed dots. This is to indicate we include the endpoints as part of the solution set. Everything between the endpoints is shaded in.
The answer in interval notation is [-1, 1]. The square brackets tell the reader to include the endpoints. This describes the interval from -1 to 1, inclusive of the endpoints.
How do we know to include the endpoints or not? By looking at the "or equal to" portion. If that is present, then we include the endpoint; otherwise, we exclude.
The original inequality [tex]|x| \le 1[/tex] is the same as [tex]-1 \le x \le 1[/tex]
The general rule is [tex]|x| \le k[/tex] turns into [tex]-k \le x \le k[/tex] for some positive number k.

Please help! Read question 5.
pls help show ALL work
Answer:
B. 5.81
Step-by-step explanation:
So to get this answer, you'd first find how much square inches are on the cheese. We know its 9/10 of the pizza and the pizza is 215 square inches. To find out what is 9/10 of the pizza you'd multiply 215 by 9 then divide by 10. That'd leave you with 193.5 then you multiply that by the cost $0.03 then get 5.805 which rounds up to 5.81.

Find the measurement of y
A-129°
B-130°
C-145°
D-134°
Answer: C
Step-by-step explanation: Since the angle measures of a heptagon measure up to 900, add all known angle measures. they equal to 755. 900 - 755 is 145.
What angle measure is complementary to a 65 angle?
Answer:
x = 25
Step-by-step explanation:
Complementary angles add to 90 degrees
x+65 = 90
Subtract 65 from each side
x = 90-65
x = 25
The Definition of Complementary Angles states that if two angles are
complementary, then the sum of their measures is 90°.
To find the complement of an angle, we take 90 degrees minus the
measure of the angle which in this case 90° - 65° or 25°.
So the complement of the 65° angle measures 25°.
In the diagram below of circle o, chords AB and CD intersect at E.
If CE = 10, ED = 6, and AE = 4, what is the length of EB?
AWARDING MAX POINTS
Answer:
The length of EB is found 15
Step-by-step explanation:
As the diagram of the circle is not given in the question, I've found the diagram of the same question from internet and attached below. So that we can have a better understanding)
We can see in the diagram the chord AB and chord CD intersect each other at point E.
Each of the chord is divided into two segments.
According to the Intersecting Chords Theorem:
Products of the lengths of line segments on each chord are equal
Which means that
(AE)(EB) = (CE)(ED)
Substitute the given values;
(4)(EB) = (10)(6)
4(EB) = 60
EB = 15
Answer:
The length of EB is found 15

There are 42 citizens called for jury duty. Eleven are randomly chosen to for the interview phase. How many different ways can the group of interviewees be made?
The quick way to get the answer is just type "42 choose 11" into Google.
Or if you want to figure it out yourself, you have 42 choices for the first potential juror, 41 choices for the second potential juror, etc.
Now before you stop there, you only care about the combination of the 11 people chosen, not what order they are selected, so you need to divide by the ways to arrange 11 people.
Final expression:
C(42,11) = (42 * 41 * 40 * 39 * 38 * 37 * 36 * 35 * 34 * 33 * 32) / (11 * 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1)

Solve the following system:
y = x + 3
3x + y = 19
O (7,4)
O(-4,7)
O (4,7)
O (4.-7)
Answer:
(4, 7) (third answer choice)
Step-by-step explanation:
In the system
y = x + 3
3x + y = 19
the first equation already gives y in terms of x. Thus we can substitute x + 3 for y in the second equation:
3x + (x + 3) = 19, which simplifies to:
4x = 16, yielding x = 4. Substituting 4 for x in the first equation, we get:
y = (4) + 3 = 7.
Thus, the solution is (4, 7) (third answer choice).

Solve for y: 3y + 6 = -45
Answer:
Step-by-step explanation:
solution :
y = -17
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3*y+6-(-45)=0
Step by step solution :
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
3y + 51 = 3 • (y + 17)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
2.1 Solve : 3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
2.2 Solve : y+17 = 0
Subtract 17 from both sides of the equation :
y = -17

y = -17
Which is the equation of a line that has a slope of One-half and passes through point (2, –3)?
Answer: y=1/2x-4
Step-by-step explanation:
Since we are given the slope, we can use the slope-intercept form to find the y-intercept.
y=1/2x+b
-3=1/2(2)+b
-3=1+b
b=-4
Now that we know our y-intercept, we can fill in our slope-intercept equation.
y=1/2x-4

The interior angles of triangle ABC measure 34°, 63°, and xº. The Interior angles of
triangle DEF measure yº, 63°, and 83º.
Which statement is true?
The triangles are similar because y=34 and there are three pairs of congruent
angles.
The triangles are similar because they each have an interior angles that
measures 63º.
The triangles are not similar because x does not equal y.
The triangles are not similar because y does not equal 34º.
Answer:
the triangles are similar because y=34 and there are three pairs of congruent angles
Step-by-step explanation:
this is correct because all of the angles in a triangle add up to 180, so if y = 34 then 34 + 63 + 83 = 180
this also means x is equal to 83 which means both triangles share all of the same angle measures

5.25x +6 =74.25
5.25x = 74.25 -6
5.25x =68.25
x = 68.25÷5.25
x = 13
Answer:
x=13
Step-by-step explanation:
1) Subtract 6 from both sides.
2) Divide by 5.25 on both sides to get x on its own.
[tex]5.25x+6=74.25\\5.25x+6-6=74.25-6\\5.25x=68.25\\\frac{5.25x}{5.25} = \frac{68.25}{5.25} \\x=13[/tex]
