Answer:
x = 119, y = 55
Answer:
x = 119°
y = 55°
Step-by-step explanation:
y + 125 = 180 {linear pair}
y = 180 - 125
y = 55°
Sum of all the angles of quadrilateral = 360
x + 55 + 72 +114 = 360
x + 241 = 360
x = 360 - 241
x = 119°
1. What is the domain of the function graphed on the grid?
Answer:
[-2,4]
Step-by-step explanation:
The domain is just asking for all the possible x values
we can see that the lowest x value is -2 and the highest is 4 which means our answer is
[-2,4]
Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the
x
-axis. The range is the set of possible output values, which are shown on the
y
-axis. Keep in mind that if the graph continues beyond the portion of the graph we can see, the domain and range may be greater than the visible values.
We can observe that the graph extends horizontally from −5 to the right without bound, so the domain is [−5,∞). The vertical extent of the graph is all range values 5 and below, so the range is (−∞,5]. Note that the domain and range are always written from smaller to larger values, or from left to right for domain, and from the bottom of the graph to the top of the graph for range.

The radius of the circle on a basketball court is 6 feet. What are the approximate circumstance and area of the circle?
Answer:
C= 38 in Approx
A=113 in^2 Aprprox
Step-by-step explanation:
Given data
radius= 6 ft
Circumference, C=2πr
substitute
C=2*3.142*6
C=37.704 in
Area A= πr^2
substitute
A=3.142*6^2
A=3.142*36
A=113.112 in^2
What is the sign of f on the interval?
The function f(x) will be sometimes positive and sometimes negative on the interval
Option (3) is correct.
What is a function?An arrangement known as a function connects inputs to essentially one output.
In other words, a function is a relationship between variables, and the nature of that relationship—for example, y = sinx and y = x +6—defines the function.
Given function:
f(x) = (x - 5) (2x - 7) (7x - 3)
The term (x - 5) will be negative if x < 5.
The term (2x - 7) will be negative if x<3.5
So, If x = 4, (x - 5) will be negative but (2x - 7) will be positive, resulting in a negative overall value.
Therefore, if x = 3, then (x - 5) will be negative, as well as (2x - 7), making the whole value negative.
Hence, the function f is sometimes positive and sometimes negative on the interval.

A bag contains 5 red marbles, 3 blue marbles, 7 yellow marbles, and 2 green marbles. Which ratio can be used to compare the red
marbles to the blue marbles?
A) 3/5
B) 3/8
C) 5/3
D) 5/8
Answer:
C) 5/3
Step-by-step explanation:
The ratio comparing red to blue marbles can be created by putting 5 and 3 together, since there are 5 red marbles and 3 blue marbles
This gets you 5/3
So, the correct answer is C) 5/3
Answer:
5/3
Step-by-step explanation:
This is because there are 5 red marbles and there are 3 blue marbles. If you put them side by side, the ratio is 5:3 or 5/3.

Answer:
-33 and -21
Step-by-step explanation:
-36, -33, -30, -27, -24, -21, -18
-36
-36 + 3 = -33
-33 + 3 = -30
-30 + 3 = -27
-27 + 3 = -24
-24 + 3 = -21
-21 + 3 = -18
formulas A=bh/2 A=bh and I have 6in 4in 6in 10in and I have to find the area
Answer:
Lots of "ifs" here.
A=bh/2 is the formula for the area of a triangle.
A=bh is the formula for the area of a rectangle or a parallelogram.
If the 6 & 4 area the base & height of a rectangle, then (6)(4) = 24 in^2
If the 6 & 10 are the base and height of a triangle, then 1/2(6)(10) = 30 in^2
Step-by-step explanation:
Nancy started the year with $425 in the bank and is saving $25 each week. Sam started the year with $705 but is spending S15 a week. Write a system of equations that model the following situation.
Define cach variables with a "Let" statement, write two equations, and solve completely.
Answer:
Step-by-step explanation:
Let x equal number of weeks and y equal money in the bank.
Nancy, y=425+25x
Sam, y=705-15x
The system of equations:
Nancy: [tex]y=\$425+\$25x[/tex]
Sam : [tex]y=\$705-\$15x[/tex]
Given:
Amount in Nancy's bank = $425
Amount saved by Nancy each week = $25
Amount in Sam's bank = $705
Amount spend by Sam each week = $15
To find:
The system of equations describing the given models.
Solution
1) Amount in Nancy's bank = $425
Amount saved by Nancy each week = $25
Let the number of weeks Nancy saving her money be 'x'.
Let the total amount of money in Nancy's bank after x weeks be 'y'.
[tex]y=\$425+\$25\times x\\y=\$425+\$25x[/tex]
The equation for Nancy:
[tex]y=\$425+\$25x[/tex]
2)
Amount in Sam's bank = $705
Amount spend by Sam each week = $15
Let the number of weeks Sam spending his money be 'x'
Let the total amount of money left in Sam's bank after x weeks ='y'
[tex]y=\$705-\$15\times x\\y=\$705-\$15x[/tex]
The equation for Sam:
[tex]y=\$705-\$15x[/tex]

A school district currently has 12,000 students. Based on declining enrollment figures, the number of students in the school district is expected to decline by 5% each year. Which of the following functions represents the number of students, S, in the school district after n years?
Answer:
S(n) = 12,000(–0.05)n
Step-by-step explanation:
The function that represents the number of students, S, in the school district after n years is [tex]S=12000(0.95)^n[/tex]
Original population , P = 12000
Rate of decline, r = 5%
r = 5/100
r = 0.05
The number of years = n
The population of students after n years will be given by the formula:
[tex]S =P(1-r)^n[/tex]
Substitute r = 0.05 and P = 12000 into the formula above
[tex]S=12000(1-0.05)^n\\\\S=12000(0.95)^n[/tex]
The function that represents the number of students, S, in the school district after n years is [tex]S=12000(0.95)^n[/tex]
