Answer:
x=3
y=11
Step-by-step explanation:
5x + 2y = 37
y = x + 8
5x+2(x+8)=37
5x+2x+16=37
7x=21
x=3
y = (3) + 8
y=11
The length of a rectangle is four times its width. If the perimeter of the rectangle is 50 m, find its length and width.
Answer:
20m
Step-by-step explanation:
let the length be x and the width be y
x = 4y
2x + 2y = 50
2(4y) + 2y = 50 ( since x = 4y )
8y + 2y = 50
10y = 50
y = 5m
x = 4y
x = 4(5)
x = 20

The diameter of a cylindrical construction pipe is 6 ft. If the pipe is 26 ft long, what is its volume?
Use the value 3.14 for it, and round your answer to the nearest whole number.
Be sure to include the correct unit in your answer.
Answer:
Step-by-step explanation:
First find the area of the circular base. The diameter is 6, so the radius is 3.
A circle is pi r square, so it is 3.14 x 3^2, = 28.26
Multiply that by the length 28.26 x 26 = 734.76, which rounds to 735 cubic feet.

Which expression are equivalent to -1+12x^2+x
Answer:
(3x+1)(4x-1)
Step-by-step explanation:
you can reorder the terms to make it less confusing to 12x^2+x-1
write x as a different 12x^2+4x-3x-1
factor out 4x 4x(3x+1)-3x-1
factor out the negative sign 4x(3x+1)-(3x+1)
factor out 3x+1
(3x+1)(4x-1)

Ask your teacher to explain it. I think that the answer is one hundred and thirty-two dollars.
Step-by-step explanation:
The simple interest follows this formula:
I = C x r% x t
– C would be the capital; the money that is provided (in this case, $1600)
– r would be the rate, which could be annual, monthly, etc. In this scenario, it's not specified. Therefore, we assume that it's annual as the time is given in years. (It would be equal to 2,75, but don't forget about the percent symbol %, which is equal to 1/100)
– Finally, t stands for time.
Remember that both time and rate must be in the same measurement (annual, monthly, etc).
You multiple everything, and the result is $132

In a school election, 3/4 of the students vote. There are 1484 votes. Find the number of students.
There are a total of
students.
Answer: 1979 students.
Step-by-step explanation:
We are told that 3/4 (75% or 0.75) of total students voted, which amounted to 1484 votes.
Letting X be the total number of students, we can write that as:
(0.75)X = 1484
X = 1978.67 total students
Now I know one classmate who wasn't all there, but I suspect even he isn't counted as 0.67 of a student. So round to the nearest whole number, 1979 students.

Round your answer to the nearest hundredth.
Answer:
Angle B = 48.19
#Rounded off to the nearest hundredth after the decimal point
Step-by-step explanation:
As Seen in the diagram is a right angled triangle and by using the infamous laws of Trigonometry, we can use the Trigonometric ratios in an indirect sense to find our answer...
Now to solve this question we need to first see what values are given to us! So the values given to us are
Hypotenuse= 3
Adjacent= 2
C= 90° (since it is the angle opposite to the hypotenuse and if observed with every right angled triangle, it will always be the case)
B=?
A=?
Questions objective= find B
I shall provide a labelled version of right angled triangle which shall aid where is the adjacent, opposite or the Hypotenuse below
Now coming back to the question,
The Opposite side of the angle we are trying to find is the adjacent and there are many Trigonometric ratios but for the sake of the question, we will need to use the one affiliated with Cosine
the way we shall interpret it is quite simple
Cos ∅°= [tex]\frac{Adjacent}{Hypotenuse}[/tex]
Now by interpreting the values from the diagram
Cos A°= [tex]\frac{2}{3}[/tex]
Now to find the actual value of a number that has an operation that disrupts the actual value, we only need to use the inverse of the operation on it to find the actual value
so by this statement we need to put an inverse of Cos
∴ A°= [tex]Cos^{-1}[/tex]([tex]\frac{2}{3}[/tex])
A°= 48.1896851
Now we need to subtract the value of 180° - (Angle A + Angle C)
by doing so we will get the value of 41.82 (rounded off to the nearest hundredth)
hence B= 41.82 °
We can add up all the values and it will be approximately be equal to 180 (keep in mind that some of these values of triangle are irrational due to which they never end)
Please do double-check it as I could've made a mistake too

Answer:
final answer is: ABC, A (-5,1), B (-4,6) and C (-1,4)
Step-by-step explanation:
Original: ABC, A (2,-1), B (1,4) and C (-2,2)
translate 3 units to the right and 2 units up: ABC, A (5,1), B (4,6) and C (1,4)
reflected over the x-axis: ABC, A (5,-1), B (4,-6) and C (1,-4)
rotated 180°: ABC, A (-5,1), B (-4,6) and C (-1,4)
Given the equations x^2 + 8x + 12 = 0 and 3x + 6 = 0, what is the common
solution?
[tex] {x}^{2} + 8x + 12 = 0 \\ = > {x}^{2} + 6x + 2x + 12 = 0 \\ = > x(x + 6) + 2(x + 6) = 0 \\ = > (x + 2)(x + 6) = 0 \\ = > x = - 2 \: \: or \: \: - 6[/tex]
[tex]3x + 6 = 0 \\ = > 3x = - 6 \\ = > x = \frac{ - 6}{3} \\ = > x = - 2[/tex]
Here, the common solution is -2.
Answer:
x = -2.

The function f is defined below.
f(x)=−2x−3
Find f(1).
Answer:
[tex]f(1)=-5[/tex]
Step-by-step explanation:
[tex]f(1)=-2(1)-3\\\\f(1)=-2-3\\\\f(1)=-5[/tex]
f(1) means to substitute x with 1 or that x=1. So since x=1 you will substitute it in where x is and then solve like a regular equation which will give you -5.
