Answer:
12
Step-by-step explanation:
zeros are the x-intercepts of any function. to find the x-intercept of this given function, we have to set y equal to 0.
0= -1/2x+6
-6=-1/2x
12=x
x=12
the x-intercept is (12,0), meaning 12 is the zero of this function.

Our class buys oranges for 25¢ each and sells them for 50¢ each. If each student in our class of 30 sells 10 oranges, how much money, in dollars, will we make?
Answer:
$75 Have a nice day! :)
here is how 50 x 10 = 500 500 x 30 = 15000 15000 divided by 2 = 7500 converted to dollars is $75
Answer:
$75.00
Step-by-step explanation:
50¢-25¢=25¢
30×10=300
300×25¢=7500¢
7500¢=$75$

Use the slope formula to find the slope m .
Answer:
B
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 3) and (x₂, y₂ ) = (3, - 5)
m = [tex]\frac{-5+3}{3-1}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1 → B

Answer:
Step-by-step explanation:put ha times 4 then divide it by ha 23helpppppppppppppppppppppppp
Answer:
By looking at the sides. BC is the same as HJ and 3 is half of 6. That goes with the rest of the equation
AC = GJ
AB = HG
So then the change in BCA is Double of GHJ
The Smith family and the Jackson family are having their basements remodeled. the Smiths contractor charge $16.50 an hour plus $289 in supplies. the Jackson’s contractor charge is $18.75 an hour and $274.60 and supplies. at how many hours of work with the total cost be the same for both families
Answer:
6.4 hrs
Step-by-step explanation:
16.5h + 289 = 18.75h + 274.6
16.5h-18.75h = 274.6-289
-2.25h=-14.4
h=14.4/2.25
h=6.4 hrs
check
6.4×16.5=105.6
105.6+289=394.6
18.75×6.4=120
120+274.6=394.6
The system of equations graphed below has how many solutions?
A. 0
B. 1
C. Infinitely many
D.2
Answer:
A. 0
General Formulas and Concepts:
Perpendicular Lines always have 1 solution.
Parallel Lines always have no solution.
Same Lines always have infinite amount of solutions.
Step-by-step explanation:
We see from the graph given that the 2 lines are parallel. Since they are parallel, they will never intersect.
Therefore, we would have no solution, or 0 solutions, as our answer.
Which equation has the same solution as this equation?
x^2-16x+12=0

What is the midpoint of a line segment with the endpoints of (-4, -4) and (6, 14)
(10, 18)
(2, 10)
(-1, 4)
(1, 5)
Answer:
The midpoint is ( 1,5)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates of the endpoints and divide by 2
( -4+6)/2 = 2/2 =1
To find the y coordinate of the midpoint, add the y coordinates of the endpoints and divide by 2
( -4+14)/2 = 10/2 =5
The midpoint is ( 1,5)

What is the measure in degrees of the smaller of the angles formed by the hands of a clock at 7:48?
Answer:
So the measure in degrees of the smaller angle formed by the hands of the clock at 7:48 is 24 degrees
Step-by-step explanation:
At 7:48 , we have two angles formed
One formed by the hour and the other formed by the minute hand
The angle formed by the hour hand will be;
7/12 * 360 = 210 degrees
Let’s now go for the minutes hand
mathematically;
60 minutes = 360 degrees
So 48 minutes will be ;
Recall;
there are 12 hours on a clock, so each hour will be 30 degrees
So the angle for 48 minutes will be;
48/60 * 30 = 24 degrees

3(2x - 7) = 5(x + 3) + 2x7
Answer:
x = -1.52016
Step-by-step explanation:
Step 1: Write equation
3(2x - 7) = 5(x + 3) + 2x⁷
Step 2: Solve for x
Distribute: 6x - 21 = 5x + 15 + 2x⁷Subtract 6x on both sides: -21 = -x + 15 + 2x⁷Add 21 to both sides: 0 = -x + 36 + 2x⁷Rearrange: 0 = 2x⁷ - x + 36Find roots by graphing: x = -1.52016Which gives the correct domain and range for the following relation: (-3, 2) , (0, 4) ,
(-3, 0) , (1, 4)
A. Domain: {-3, 0, 4}, Range: {2, 4}
B.
Domain: {-3, 0, 1}, Range: {0, 2, 4}
C.
Domain: {-3, 0, 4}, Range: {0, 2, 4}
D.
Domain: {-3, 0, 1}, Range: {2, 4}

Problem: The average cost of a compact car at a certain dealership over the last 10 years has ranged from $15,000 to $24,500. Suppose you were going to plot these points on a coordinate grid.
A) What is a good scale [range] would be good to use for the y-axis to make a nicely sized graph? Explain your reasoning.
B) What is a good interval [step size] would be good to use for the y-axis to make a nicely sized graph? Explain your reasoning.
C) What is a good scale [range] would be good to use for the x-axis to make a nicely sized graph? Explain your reasoning.
D) What is a good interval [step size] would be good to use for the x-axis to make a nicely sized graph? Explain your reasoning.
Note: The step size the distance between the marks on the graph, and the range is the maximum and minimum values (ex: -10 to 10).
Answer:
a. 10 by 25,000
b. 25,000 interval because the x and y axis would both have 10 marks
c. 1-10 because it meets the exact number needed, and gives the graph a nice, square look
d. 1 because it will give the graph a nice size and perfect range.

The volume of a rectangular pool is the product of the pool's area and depth. Suppose a pool that is 12 feet deep has
a volume of 10368 ft? What is the area of the pool?
The area of the pool is
square feet.
The area of the pool is the product of the pool's length and width. Suppose the pool's length is 24 ft. What is the
pool's width?
The pool's width is
feet
Answer:
The area of the pool is [tex]864\ ft^2[/tex]
The pool's width is 36 ft
Step-by-step explanation:
Volume and Area
The volume of a rectangular pool is the product of the pool's area and depth. We are given the pool's depth d=12 feet and the pool's volume V=10368 [tex]ft^3[/tex]
Since:
[tex]V= d*A[/tex]
Solving for A:
[tex]\displaystyle A=\frac{V}{d}=\frac{10368}{12}=864\ ft^2[/tex]
The area of the pool is [tex]864\ ft^2[/tex]
Now we calculate the pool's width, knowing the area is the product of the pool's length and width. Knowing the length is L=24 ft:
[tex]A=L*W[/tex]
Solve for W:
[tex]\displaystyle W=\frac{A}{L}=\frac{864}{24}=36[/tex]
The pool's width is 36 ft
The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 3 to 5. If there were
4104 total votes, how many yes votes were there?
Answer:
the residents of a city voted on whether to raise property taxes. The ratio of yes to no votes was 5 to 8. If there were 6776 no votes, what was the total number of votes?
-------
5 to 8 is the same as 5x to 8x where 8x is the number of no votes.
----
If 8x = 6776, then x = 847
