x+x2 +2=44 solve the equation quick
Answer:
x=10.5 or x=6=x=−7
Step-by-step explanation:
x+x^2+2=44
x+x(x)+2=44
2x(x)+2=44 1. -2 on both sides
2x^2=42
2x(2x)=42
4x=42 2. /4 on both sides
x=10.5
Answer:
x = -7, 6.
Step-by-step explanation:
x+x2 +2=44
x^2 + x - 42 = 0
(x - 6)(x + 7) = 0
x =-7, 6
A 20 ft. long piece of lumber is cut such that the first piece is 4 ft. longer than three times the second piece. what is the length of each piece?
Answer:
2nd = 4ft.
1st = 16ft
Step-by-step explanation:
2nd = x
1st = 3x + 4
Piece of rope = 20ft.
(3x + 4) + x = 20
4x + 4 = 20
4x = 16
x = 4 (second piece)
First
3x + 4
3(4) + 4
12 + 4 = 16
GIVING BRAINLIESTT!!
Answer:
15) A
Step-by-step explanation:
4x-2 + 7x + 17 = 180
11x + 15 = 180
11x = 165
x = 15
Because the two angles (4x-2 and 7x+17) are linear, we can say that they add up to 180 degrees.
4x-2+7x+17 = 180 Now, simplify like terms
11x + 15 = 180
11x = 165
x = 15
Thus, the value of x would be 15 (choice 1)

Find the volume of a cone with the base of 10 and height of 6
Answer:
Answer = 157
Step-by-step explanation:
The formula to finding the volume of a cone is h(pi)(r^2)/3. We know that the height is 6 and the base is 10. This means that the radius is 5 because it is 1/2 of the base. Now we plug in our numbers into the equation and get 157!

Price of next model:
Answer:
increase in price = $6664
price of next model = $56664
Step-by-step explanation:
(11.9 ÷ 100 ) x 56000 = $6664
56000 + 6664 = $56664

Using the equation, y=5x²−17x −12, determine the y-intercept.
A) (0, -12)
B) (4, 0)
C) (1.7, -26.4)
D ) (0, 12)
Answer:
A
Step-by-step explanation:
to find the y- intercept let x = 0 in the equation and solve for y
y = 5(0)² - 17(0) - 12 = 5(0) - 0 - 12 = 0 - 12 = - 12
then the y- intercept is (0, - 12 )
Answer:
[tex]\huge\boxed{\sf (0,-12)}[/tex]
Step-by-step explanation:
Given equation:[tex]y=5x^2-17x-12[/tex]
y-intercept is the point where x = 0
Put x = 0 in the above equation.
[tex]y=5(0)^2-17(0)-12\\\\y = 0-0-12\\\\y=-12[/tex]
So, y = -12, when x = 0.
Ordered pair = (x,y) = (0,-12)

Isabella has a total of 150 music CD's.She loves rock music and alternative music. The number of alternative music CD's is three more than twice that of the rock music CD's that she owns .
(a). Write down two equations that represent this information.
(b). Draw the two graphs that represent these equations on the same set of axes .
(C). Show where you can read off how many Rock CD's Isabella owns .
The system of equations that we need to solve is:
x + y = 150y = 2x + 3And the solution is x = 49 and y = 101.
How to solve the system of equations?
Let's define the variables:
x = number of CDs of rock music.y = number of CDs of alternative music.We know that the total number of CDs is 150, then:
x + y = 150
And we know that:
y = 2x + 3
Then the two equations that represent the information (and conform a system of equations) are:
x + y = 150
y = 2x + 3
b) The graphs of the two equations can be seen below.
c) To find the solution, we just need to see where the graphs intercept.
We can see that the intercept is (49, 101), this means that:
Isabella has 49 rock music CDs and 101 alternative music CDs.

Regardless of how the graph is oriented in the standard
(x,y) coordinate plane, NO graph in one of the
following categories has a vertical line of symmetry.
Which one?
F. Line
G. Square
H. Pentagon
J. Parallelogram
K. Scalene triangle
Answer:
the answer is j because it's impossible to draw a line through the center of any parallelogram that divides the figure into two equal halves that are mirror images of each other
Out of the given options, the shape that does not have a vertical line of symmetry is J. Parallelogram.
The correct answer is J. Parallelogram.
A vertical line of symmetry means that if a line is drawn vertically through the shape, the two halves will be mirror images of each other.
In the case of a line (F), it is one-dimensional and does not have an area, so it does not have any symmetry.
A square (G) has four sides of equal length and four right angles. It has both vertical and horizontal lines of symmetry, dividing it into four congruent quadrants.
A pentagon (H) is a five-sided polygon. Depending on its shape and orientation, it may or may not have a vertical line of symmetry. For example, a regular pentagon does have a vertical line of symmetry, while an irregular pentagon may not.
A parallelogram (J) is a four-sided polygon with opposite sides that are parallel and equal in length. It does not have a vertical line of symmetry because its opposite sides are not mirror images of each other.
A scalene triangle (K) is a triangle with no equal sides or equal angles. It does not have a vertical line of symmetry because its sides and angles are not symmetric.

Jeff has a balance of $2,513.77 on his credit card. He would like to pay off his card over the course of a year and a half by making identical monthly payments. The APR on his card is 10.66%, compounded monthly. Assuming that Jeff makes no additional purchases with his card, how much will he have to pay every month to reach his goal? (Round all dollar values to the nearest cent.) a. $151.73 b. $162.57 c. $139.65 d. $147.64 Please select the best answer from the choices provided A B C D
Using the monthly payment formula, it is found that the amount he will have to pay is given as follows:
a. $151.73.
What is the monthly payment formula?It is given by:
[tex]A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}[/tex]
In which:
P is the initial amount.r is the interest rate.n is the number of payments.In this problem, the parameters are given as follows:
P = 2513.77, r = 0.1066, n = 1.5 x 12 = 18.
Hence:
r/12 = 0.1066/12 = 0.008883.
[tex]A = 2513.77\frac{0.008883(1 + 0.008883)^{18}}{(1 + 0.008883)^{18} - 1} = 151.73[/tex]

Solve the system of equation using ELIMINATION (solve for x)
x + 3y = 14
-x + y = 10
Answer:
x = -1.5 , y = 5.17
Step-by-step explanation:
Solve the system of equation using ELIMINATION (solve for x)
x + 3y = 14
-x + y = 10
Solution
x + 3y = 14 ------- equation 1 * 1
-x + y = 10 ------- equation 2 * 3
x + 3y = 14 ------- equation 3
-(-3x + 3y = 30)------ equation 4
Using the ELIMINATION METHOD.
x-(-3x) + 3y-3y = 14-30
4x = -6
x = [tex]\frac{-6}{4}[/tex]
x = -1.5
Substuting -1.5 into equation one
x + 3y = 14
-1.5 + 3y = 14
Adding 1.5 to both sides
-1.5 + 1.5 +3y = 14 +1.5
+3y = 15.5
Dividing by the coeffient of y
[tex]\frac{3y}{3} = \frac{15.5}{3}[/tex]
y = 5.166666666666
y =5.17
Therefore x = -1.5 , y = 5.17
