Answer:
Assuming that the x2 is x squared, B
Step-by-step explanation:
(1)(1) + 5(1) - 6 = 1 + 5 - 6 = 6 - 6 = 0
(-6)(-6) + 5(-6) - 6 = 36 - 30 - 6 = 6 - 6 = 0
Answer:
B
Step-by-step explanation:
Let's solve using factoring.
x²+5x-6=0
5 is the sum of the numbers, while -6 is their product.
Think: which two numbers add up to 5, but when multiplied, equal -6?
Those numbers are -1 and 6.
Now factor the polynomial:
(x-1)(x+6)=0
split into parts:
(x-1)=0
x-1=0
x=1
(x+6)=0
x+6=0
x=-6
So B

Quadrilateral JKLM is graphed in the coordinate plane. Under which transformation
would the image of JKLM be similar to JKLM?
9514 1404 393
Answer:
A
Step-by-step explanation:
Rigid transformations and dilation will result in similar figures. Choices B, C, and D are not rigid transformations or dilations, but are different stretches in one direction than another.
The transformation of A is a dilation by a factor of 2 and reflection over the y-axis. It results in similar figures.
Find the value of x :>
Answer:
x = 61°
Step-by-step explanation:
Since the lower left angle equals to 90°, the other angle on the right must also equal 90°. Subtract 29 from 90° to get 61° as your x value and as your final angle answer.
Answer:
61°
Step-by-step explanation:
The dotted angke is a right angle which is 90° so,
We can solve for x using algebra
90+x+29=180
x+119=180
x=180-119
x=61

A used book store also started selling used CDs and videos. In the first week, the store sold a combination of 40 CDs and videos. They charged $4 per CD and $6 per video and the total sales were $180. Determine the total number of CDs and videos sold.
I kind of need to know how to solve. I have more q's like this but if I know how to, I might be able to do it.
Answer:
They sold 10 videos and 30 CDs
Step-by-step explanation:
So, you need two different equations-
We will use c to represent CDs and v to represent videos
So-
c + v = 40
4c + 6v = 180
Single out a variable in the first equation-
v = 40 - c
Because this is equal to v, insert it where v is in the second equation-
4c + 6(40 - c) = 180
Multiply-
4c + 240 - 6c = 180
Solve-
-2c + 240 = 180
-2c = -60
c = 30
Now that you know c, use first equation to find v-
30 + v = 40
v = 10
So c = 30 and v = 10
Solve for x (PLEASE HELP!!!)
Answer:
it's answer is 2
Step-by-step explanation:
take the reference angle as 60°
base (b) = x
hypotenuse (h) = 4
Now
cos 60 ° = b / h
1/2 = x / 4
1/2 * 4 = x
Therefore x = 2

You are decorating your bedroom. To get the paint colour you want, you mix 2 parts red with 1 parts cream and 3 part blue. How much blue paint will you need to mix with 4 litres of red?. Single line text.
Answer:
6 litres of blue color should be mixed.
Step-by-step explanation:
To get the paint color as per my wish, paint of different colors are mixed in the ratio = Red : Cream : Blue
= 2 : 1 : 3
In this mixture, ratio of red and blue color = 3 : 2
This ratio will be constant for any amount of mixture.
Therefore, [tex]\frac{\text{Amount of Blue color}}{\text{Amount of red color}}=\frac{3}{2}[/tex]
[tex]\frac{b}{4}=\frac{3}{2}[/tex]
b = [tex]\frac{3}{2}\times 4[/tex]
b = 6 litres
Therefore, 6 litres of blue color should be mixed with the 4 litres of red color.

find the area of the shaded region of the trapezoid.
Answer:
B
Step-by-step explanation:
Area of Trapezoid
Area = (b1 + b2)*h/2
Area = (9 + 13)*11 /2
Area = (22) * 11/2
Area = 121 sqr. units.
Area of the unshaded triangle
Area = 1/2 b * h
Area = 1/2 9 * 11
area = 49.5
Area of the shaded region
Area = 121 - 49.5
Area = 71.5

You pay a registration fee and a monthly fee to join a local fitness center. The table shows the total cost of joining the fitness center for different numbers of months.
Write an equation that represents the total cost (in dollars) of joining the fitness center after a certain number of months.
Answer:
100 divided by 3=33.33 therefore 33.33 per month
Step-by-step explanation:
Equation:
33.33x9= 299.97
This is for 9 months
An equation that represents the total cost (in dollars) of joining the fitness center after a certain number of months is; y = 20x + 40
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
WE have to pay a registration fee and a monthly fee to join a local fitness center.
The table represents the total cost of joining the fitness center for different numbers of months.
Then the equation is;
y - 100 = 20(x - 3)
y = 20x - 60 + 100
y = 20x + 40
Hence, an equation that represents the total cost (in dollars) of joining the fitness center after a certain number of months is; y = 20x + 40

Mr Jones is 4 years older than his wife and 31 years older than his son.All three ages add up to 82 years. If Mr Jones is x years old find the value of x and find the ages of his wife and son
Answer:
So the age of Mr.Jones = 39 yrs. |
the age of his wife = 39-4 = 35 yrs.|
and the age his son = 39-31 = 8 yrs.|
Step-by-step explanation:
Let the age of Mr.Jones = x
So, the age of his wife = x-4 (wife is younger by 4 years)
and the age of his son = x-31 (son is younger by 31 years)
Sum of their ages = x + (x-4) + (x-31) = 82
= x + x - 4 + x - 31 = 82 (By removing the brackets)
= 3x - 35 = 82
= 3x = 117 (By adding 35 both the sides)
= x = [tex]\frac{117}{3}[/tex]= 39

there were 135 wagons in two station together.
after they moved 45 wagon from the first station to the second station, and 36 wagon from the second station to the first station,
it turned out, that now there were
1 1/2 (3/2) times more wagons in first station, than in second station.
question: how many wagons were on each station in the beginning?
(I need detailed answer please, and I'll mark u as brainliest )
Answer:
[tex]The\ number\ of\ wagons\ on\ Station\ A\ at\ the\ beginning\ = 90\\ The\ number\ of\ wagons\ on\ Station\ B\ at\ the\ beginning\ =45[/tex]
Step-by-step explanation:
[tex]We\ are\ given:\\Total\ no.\ of\ wagons\ in\ both\ the\ stations=135\ wagons\\Now,\\Let\ both\ the\ stations\ be\ denoted\ as\ Station\ A\ and\ Station\ B.\\\\Let\ the\ number\ of\ wagons\ on\ Station\ A\ at\ the\ beginning\ be\ x\\Let\ the\ number\ of\ wagons\ on\ Station\ B\ at\ the\ beginning\ be\ y\\Hence,\\We\ are\ also\ given\ that,\\Number\ of\ wagons\ that\ removed\ from\ Station\ A=45\\Number\ of\ wagons\ that\ were\ added\ to\ Station\ A=36\\Similarly,\\[/tex]
[tex]Number\ of\ wagons\ that\ removed\ from\ Station\ B=36\\Number\ of\ wagons\ that\ were\ added\ to\ Station\ B=45\\Hence,\\The\ final\ number\ of\ wagons\ in\ Station\ A=x-45+36=x-9\\The\ final\ number\ of\ wagons\ in\ Station\ B=x+45-36=y+9\\Now,\\As\ we\ already\ know,\\No.\ of\ wagons\ in\ Station\ A\ at\ the\ beginning\\ +No.\ of\ wagons\ in\ Station\ B\ at\ the\ beginning=135\\Hence,\\x+y=135\\y=(135-x)\\Hence,\\The\ final\ number\ of\ wagons\ in\ Station\ B=y+9=(135-x)+9=(144-x)[/tex]
[tex]We\ are\ also\ given\ that,\\Final\ number\ of\ wagons\ in\ Station\ A=\frac{3}{2}* Final\ number\ of\ wagons\\ in\ Station\ B\\Hence,\\(x-9)=\frac{3}{2}*(144-x)\\By\ simplifying:\\2(x-9)=3(144-x)\\2x-18=432-3x\\3x+2x=432+18\\5x=450\\x=\frac{450}{5}=90\\Hence,\\The\ number\ of\ wagons\ on\ Station\ A\ at\ the\ beginning\ = x=90\\ The\ number\ of\ wagons\ on\ Station\ B\ at\ the\ beginning\ =y=(135-x)=(135-90)=45[/tex]
