Which of the following is an even function?
f(x) = x1
Of(x) = x2 - 1
Of(x) = -3x
O Rx) = 3/8
Answer:
[tex]f(x) = x^{2} - 1[/tex]
Step-by-step explanation:
The definition of even function is: [tex]f(x) = f(-x)[/tex]
I am going to assume the second option is [tex]f(x) = x^{2} - 1[/tex] and the answer.
[tex]f(x) = x^{2} - 1\\f(-x) = (-x)^{2} - 1 = x^{2}-1[/tex]

PLEASE HELP ME IVE BEEN STUCK BECAUSE I THOUGHT THAT 12/60 WAS 1/5 SIMPLIFIED??
Answer:
1/3, 33.33%
Step-by-step explanation:
The full square is 6x6 which means there are 36 tiles in total. The shaded area is 3x4 which is 12. 12/36 is 1/3 simplified or 33.33%.
Answer:
1/3 and 33.33℅
Step-by-step explanation:
total number of rectangles is 36 and the shaded are 12
so 12/36 =1/3
1/3= 0.3333
to change to percent we multiply by 100
0.3333×100℅ = 33.33℅

The vendor of a coffee cart mixes coffee beans that cost $9 per pound with coffee beans that cost $5 per pound. How many pounds of each should be used to make a 75-pound blend that sells for $6.00 per pound
Answer:
56.25 pound of the coffee that costs $5 per pound is needed
18.75 pound of the coffee that costs $9 per pound is needed
Step-by-step explanation:
Let the number of pounds be x and y respectively
The total pounds is 75;
So;
x + y. = 75 •••••••(i)
Total cost of first type
9 * x = $9x
Total cost of second type;
5 * y= $5y
75 pound at $6 per pound; total cost of this is;
6 * 75 = $450
Thus;
9x + 5y = 450 ••••••••(ii)
From i, x = 75-y
Put this into ii
9(75-y) + 5y = 450
675 -9y + 5y = 450
4y = 675-450
4y = 225
y = 225/4
y = 56.25
x = 75 - y from i
x = 75-56.25
x = $18.75

A won a race at the local fair by running 10.5 miles in exactly 2 hours. At this constant rate, how long does it take the same dog to run the 21 mile state fair race? Use ratio reasoning to solve. * 1 point
Answer:
The dog will run the 21-mile race in 4.04 hours
Step-by-step explanation:
The first thing we need to do is find out how far he ran the race at the local fair in 1 hour.
To do this, we can set up a simple relationship:
If he ran 10.5 miles in 2 hours,
He will run x miles in 1 hour
Cross multiplying, we have
x = (10.5 X 1)/2 = 5.25 miles in 1 hour.
We can now comfortably say that he runs at the rate of 5.2miles/hr
He now goes to the state fair race, which is 21 miles long.
if he runs at the rate of 5.2 miles in 1 hour,
He will run 21 miles in y hours
y = 21 / 5.2 = 4.04 hours
The dog will run the 21-mile race in 4.04 hours

Elena runs for 28 seconds and finishes at 250 seconds what is her velocity please explain
Answer:
The velocity is 8.93 meters/second.
Step-by-step explanation:
It is given that Elena runs for 28 seconds and finishes at 250 meters.
Here the displacement is 250 meters and the time is 28 seconds.
We know that [tex]V=\dfrac{\text{Displacement}}{\text{Time}}[/tex]
Substitute displacement = 250 and time = 28 in above formula.
[tex]V=\dfrac{250}{28}[/tex]
[tex]V\approx 8.93[/tex] meters/second
Hence, the velocity is 8.93 meters/second.

Jermyn is converting £263 into $. He knows that £1 = €1.14 and €1 = $1.25. How many $ will Jermyn get? Give your answer to 2 dp
Answer:
£263 = €299.82
€299.82 = $374.775
Answer:
374.78
Step-by-step explanation:
Essentially it would be 374.77 but it requires 2 decimal places so you have to round up to 78 and that's the answer hope it helps!
5x-2y=12
6x+2y=32
find the solution
Answer:
(4,4)
Step-by-step explanation:
There are two ways that you can solve this. You can solve it with the help of technology or you can solve it traditionally. I will show how to do it in both ways so you can pick which way you want to solve it.
Traditional Method:
5x - 2y = 12
6x + 2y = 32
Look at the variables and numbers in both equations. One of them has to be the same value but have to have opposite signs. The 2y in both equations are the same value but have different signs. That's what we want. We can add everything in the equation now. (5x + 6x), (-2y + 2y), and (12 + 32).
11x = 44
To get x alone, Divide each side by 11. Then we will get the value of x.
11/11x = 44/11
x = 4
Horray! We got x, but what about y? Pick one of the equations. I will go with 5x - 2y = 12. Substitute the x value inside the equation.
5(4) - 2y = 12
20 - 2y = 12
-2y = -8
y = 4
Good! We figured out y. Now we know the solution! The solution is (4,4).
Technology Method:
Grab a graphing calculator. Enter the equations. You will see two lines. Look at where they intersect. The point where they intersect is the solution. That line is (4,4). You could also do this on a piece of paper by graphing the equations.
I hope this helps! Let me know if you need any more help or if I got anything wrong.

Taiga wants to make a circular loop that she can twirl around her body for exercise. He will use a tube that is 2.5 meters long. Estimate the diameter of Taiga's exercise hoop? Round your answer to the nearest thousandth of a meter.
Answer: 0.796 meters
Step-by-step explanation:
Circumference of circle = [tex]2\pi r[/tex] , where r=radius
Here, Circumference of loop = 2.5 meters
i.e. [tex]2\pi r=2.5[/tex]
[tex]\Rightarrow\ r=\dfrac{2.5}{2\pi}[/tex]
[tex]\Rightarrow\ r=\dfrac{2.5}{2\times\dfrac{22}{7}}\\\\\Rightarrow\ r=\dfrac{2.5\times7}{2\times22}\\\\\Righttarrow\ r=0.398\ m[/tex]
Diameter = 2r = 2(0.398) = 0.796 meters
Hence, The diameter of Taiga's exercise hoop = 0.796 meters
Given that D( x ) = 2 x , select all of the following that are true statements.
D( x ) is a direct variation.
D( x ) is a function.
D( x ) is a rule for the set of points (5, 10), (6, 12) and (-2, -4).
x is the dependent variable.
D(6) = 3
Answer:
3rd
Step-by-step explanation:
Answer:
D(x) is a function. TRUE. It is a function of x.
x is the dependent variable. FALSE. x is the independent variable because the function is expressed in terms of the independent variable.
D(6) = 3. FALSE. D(6) = 2(6) = 12. D(6) should be equal to 12.
D(x) is a direct variation. TRUE. This holds true to the definition of direct variation where one variable is related to the other variable at the same constant multple. In this case, it is 2.
D(x) is a rule for the set of points (5, 10), (6, 12) and (-2, -4). TRUE. If you replace x with the first coordinate, the function would be equal to the corresponding second coordinate.

Which statement explains whether w = 8 is a solution to the equation 5 + w = 58?
(4-8)( 12, 8)
Write the equation of a line using slope intercept form
Answer:
y=2x-16
Step-by-step explanation:
so gradient is 8-(-8)/ 12-4
so 16/8 which is 2
equation of line is: y= 2x+c
substitute the values into x,y
8=2(12)+c
8=24+c
8-24=c
-16= C
this is because when it goes over the equal sign it becomes negative so now the equation is y=2x-16
Answer:
Y=2x+16

Anna is in a cave 48 feet below the cave entrance. She descends 11 feet, then ascends 15 feet. Find he
new position relative to the cave entrance.
Answer:
-44 feet deep
In other words: 44 feet below ground
Step-by-step explanation:
First we have to write out the equation that the problem creates for us.
-48 - 11 + 15
Next we just have to subtract and add:
-48-11 = -59
-59+15 = 44
There we go! That's our answer.
