A function is shown f(x) = 2/3x + 3
What is the value of f(12)?
Answer:
f(12) = 11
Step-by-step explanation:
To evaluate f(12) substitute x = 12 into f(x) , that is
f(12) = [tex]\frac{2}{3}[/tex] × 12 + 3 = 8 + 3 = 11

Answer:
C
Step-by-step explanation:
Solve for y to find the inverse:
x = f(y)
x = y/3 -2
x +2 = y/3
y = 3(x +2)
f⁻¹(x) = 3(x +2) . . . . the inverse function

A farmer has a rectangular field that measures 100 feet by 150 feet. He plans to increase the area of the field by 20%. He will do this by increasing the length and width by the same amount, x. Which equation represents the area of the new field? WILL GIVE BRAINLIEST
Answer:
(100 + x) x (150 + x) = 18,000 ft^2
Step-by-step explanation:
area of a rectangle = length x width
Area of the original field = 15,000
Area after 20% increase = 1.2 x 15,000 = 18,000
Increase i length = 100 + x
increase i width = 150 + x
Area = (100 + x) x (150 + x) = 18,000 ft^2
Answer
C
Step-by-step explanation:
It would be (100+x)(150+x) = 18,000 (incase if the answer isn't C for those)
Sam paid $8.28 for 18 stamps. At this rate, how much would it cost Sam to buy 12 stamps?
Answer: $5.52
Step-by-step explanation:
Given: Sam paid $8.28 for 18 stamps.
Thus, the cost of 18 stamps = $8.28
Then the cost of 1 stamp=
Thus, the cost of 1 stamp=$0.46
With the same rate , the cost of 12 stamps=
Therefore, the cost of 12 stamps= $5.52
hence, it costs $5.52 to Sam to buy 12 stamps.
8.28÷18 = 0.46
0.46 is the cost if 1 stamp
cost of 12 stamps= 0.46×12 = $5.52

Sarah is making a cake using a recipe that requires
3
4
cup of milk for every
1
2
cup of sugar. How many cups of milk, written as a fraction, should Sarah use for 1 cup of sugar?
Answer:
6/4 or 1 1/2
Step-by-step explanation:
Because Sarah is using 1 cup of sugar or two 1/2s, she will have to multiply 3/4 by 2. 2 can also be shown as 2/1 if its easier for you.
to multiply fractions together, multiply the numerators together for your numerator and your denominators together for your denominator.
3/4 × 2/1 = 6/4
if you like, you can write 6/4 as a mixed fraction by saying 1 1/2
Answer:
6/4

A bridge can hold at most 80,000 pounds. A tow truck weighing 7,000 pounds is broken down on the bridge. If the average car weights 2,800 pounds, how many cars can safety be on the bridge with the broken down tow truck.
Answer:
26
Step-by-step explanation:
x = number of cars that an safety be on the bridge with the broken down tow truck.
The equation that can be used to determine the answer =
total weight the bridge can accommodate = total weight of truck + total weight of cars
total weight of cars = weight of a car x total number of cars
2800x
80,000 = 7000 + 2800x
collect like terms
80,000 - 7000 = 2800x
73,000 = 2800x
x = 73,000 / 2800
x = 26

Is algebra.
Answer:
B
Step-by-step explanation:
The first one is a binomial. It has two different terms on either side of the middle minus sign. y is raised to the 4 th power so that is degree 4. The answer is b
The second problem is ordered as 4 3 1 2
The powers determine the degree. The terms are all different and the number of terms is determined by the powers of the letters in the terms.

The rate at which a mountain is eroding is given by y=0.5x, where y represents the amount of erosion in millimeters and x represents the amount of time in years. A field is eroding at a rate of 2 millimeters per year. Is the field or the mountain eroding at a faster rate? By how much?
Answer:
Field
Field is eroding 4 times faster than the mountain.
Step-by-step explanation:
[tex]y[/tex] = The amount of erosion in millimeters
[tex]x[/tex] = Number of years passed
[tex]y=0.5x\\\Rightarrow \dfrac{y}{x}=0.5[/tex]
The rate at which soil is eroding in the mountain is 0.5 millimeters per year.
The rate at which the field is eroding is 2 millimeters per year.
The field is eroding faster than the mountain.
[tex]\dfrac{m_f}{m_m}=\dfrac{2}{0.5}\\\Rightarrow m_f=4m_m[/tex]
So the field is eroding 4 times faster than the mountain.
how many different right triangles are there with a hypotenuse of lenght 5 cm
Answer:
Draw a horizontal line across a page of paper, somewhere in the middle. Mark a point A on the line, toward the left margin.
Spread open a compass to make good sized circle, but so that if the point of the compass is on the point you drew, the pencil fits on the page, both below the top edge and to the left of the right edge of the page. Draw the arc, from roughly the 12 O’Clock position over and down to the intersection of the line segment, at the 3 O’Clock position.
Call the opening of your compass, the radius of the arc you just drew, “5 units”.
Pick any point on the arc between the 12 and 3 positions, B. Drop a line down from that point B, perpendicular to the original horizontal line. Label the point that it intersects the horizontal line, C.
ABC is a right triangle with hypotenuse 5. Do this again with a point a little closer to the 3 O’Clock position. It’s another right triangle with hypotenuse 5.
Indeed, as you get closer to the right, along the arc, the height of the triangle declines, but the width of the triangle increases. The hypotenuse remains 5 in all cases. We picked points on the circle. We could have picked points on the horizontal line first, and raised perpendicular lines until they intersected the circle. Each point forms a distinct right triangle.
There are as many possible right triangles as there are possible points in a line segment.

If the perimeter of the square is 36 cm. What is the area of the non-shaded region?
Answer:
either 20.25π or around 63.6173
Step-by-step explanation:
So first you find the side length of the square which is the perimeter/4 so in this case, 9. 9/2 will give you the radius of the circle and just solve for the area using the formula a=πr^2
Helppppppppppppppppp
Answer:
CA = 32
Step-by-step explanation:
By intersecting chords theorem:
[tex]12(4x + 1) = 14(3 + 3x) \\ \\ 48x + 12 = 42 + 42x \\ \\ 48x - 42x = 42 - 12 \\ \\ 6x = 30 \\ \\ x = \frac{30}{6} \\ \\ x = 5[/tex]
CA = 14 + ( 3 + 3x)
CA = 14 + ( 3 + 3*5)
CA = 14 + ( 3 + 15)
CA = 14 + 18
CA = 32
Find X and TU
Show all the work
Answer:
x = 10, TU = 24
Step-by-step explanation:
The midsegment TU is half the sum of the parallel bases, that is
[tex]\frac{1}{2}[/tex] (3x + 2+ 2x - 4 ) = 2x + 4 ( multiply both sides by 2 to clear the fraction )
5x - 2 = 4x + 8 ( subtract 4x from both sides )
x - 2 = 8 ( add 2 to both sides )
x = 10
Then
TU = 2x + 4 = 2(10) + 4 = 20 + 4 = 24
The graph shows the relationship between the number of apples and their cost. For the point (1, r), what is the value of r?
Answer:
C.
Step-by-step explanation:
When you check the point that is on X, it is a little over halfway to the point 1,2. It would be like 1,1.5 or 1,1.6.
5/3 is the equivalent to 1.6 so that answer would make the most sense.
Answer:
5/3
Step-by-step explanation:
3 Apples cost $5, so each apple cost 5 divided 3 ( 5 over 3).
On Tuesday, a local hamburger shop sold a combined total of 381 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the number
of hamburgers sold. How many hamburgers were sold on Tuesday?
Answer:
127 hamburgers
Step-by-step explanation:
let c = # of cheeseburgers
let h = # of hamburgers
c = 2h (The number of cheeseburgers sold was two times the number
of hamburgers sold.)
h + c = 381 (combined total)
h + 2h = 381
3h = 381
h = 127

What is the value of x? (Round to the nearest tenth.)
Answer:
707.9
Step-by-step explanation:
Let find some missing angles using the triangle interior theorem,
The triangle is split up into 3 triangles, (2 right triangles and 1 scalene triangle.)Let find the missing angle of the triangle on the top.Using triangle interior theorem, the missing angle is 48.We can use law of sines to find the missing side since we know.
We know the angle opposite of the side we trying to find, 42We know a side and it opposite side, 518 and 48.Let y represent the top triangle vertical side.
[tex] \frac{y}{ \sin(42) } = \frac{518}{ \sin(48) } [/tex]
[tex]y = \frac{518}{ \sin(48) } \times \sin(42) [/tex]
[tex]y = 466.4[/tex]
Know let find the missing side of the bottom The missing angle near the top triangle right angle is 90 degrees. Using triangle interior theorem, the .missing angle is 65.We can law of sines since we know a side and the angle opposite of it, and we are trying to find a side and we know an angle opposite of it.
Let z represent the missing side of the bottom triangle vertical side,
[tex] \frac{518}{ \sin(65) } = \frac{z}{ \sin(25) } [/tex]
[tex] \frac{515}{ \sin(65) } \times \sin(25) = z [/tex]
which is about
[tex]241.5[/tex]
Y and Z both add to X so add the vertical side together
[tex]466.4 + 241.5 = 707.9[/tex]
So
[tex]x = 707.9[/tex]
