The length of the line segment EF is 106.
The distance between the end points of DF is equal to 9x-39.The distance between the end points of DE is equal to 47.The distance between the end points of EF is 3x + 10.Applying the logic that the line segments are a part of the same straight line, we can conclude thatThe length of the line segment DF is equal to the sum of the lengths of the line segments DE and EF.DF = DE + EF.9x - 39 = 47 + (3x + 10)9x - 6x = 47 + 10 + 393x = 96x = 32The length of the line segment EF is 3*32 + 10.The length of the line segment EF is 96 + 10.Thus, the length of the line segment EF is 106.To learn more about distance, visit :

Answer: (x-2)(x+y)
Step-by-step explanation:
x² + xy-2x-2y=
x(x+y)-2x-2y=
x(x+y)-2(x+y)=(x-2)(x+y)
Answer:
[tex] \large \boxed{(x- 2)(x+y)}[/tex]
Step-by-step explanation:
[tex] {x}^{2} + xy - 2x - 2y[/tex]
We are given with 4 terms. so use grouping method for factoring. To factor the given expression we take out GCF
[tex]x^2- 2x +xy - 2y[/tex]
we group first two terms and last two terms
then take out GCF from each group
[tex]x(x-2) +y(x-2)[/tex]
Now take out common factor x-2

A bag contains 3 red
marbles, 5 blue marbles and 4 green marbles. If three marbles
are drawn out of the bag, what is the exact probability that all three marbles drawn
will be blue?
Can y’all help me please??
Answer:
[tex]\frac{5}{42}[/tex]
Step-by-step explanation:
It makes a difference if the marbles are place bag into the bag after selecting. Since this is not stated, I am assuming that once a marble is selected, it is not placed back in the bag.
[tex]\frac{5}{9}[/tex] x [tex]\frac{4}{8}[/tex] x [tex]\frac{3}{7}[/tex] = [tex]\frac{60}{504}[/tex] This simplified would be [tex]\frac{5}{42}[/tex] The 5 represent the number of blue marbles available our of 9 total marbles. Next, we only have 4 blue marbles available out of a total of now 8 marbles and lastly, for the third draw we only have 3 blue marbles available and only 7 total marbles are left.
If the marbles are replaces that changes the problem and the answer would be [tex]\frac{5}{9}[/tex] x [tex]\frac{5}{9}[/tex] x [tex]\frac{5}{9}[/tex] = [tex]\frac{121}{729}[/tex]

a godown had a stock of cloth of Rs.160000. Due to a fire a part of the merchandise, wroth Rs. 20000, was completely destroyed. find the loss percent?
The loss percentage of cloth is 12.5%.
Stock of cloth = Rs. 1,60,000
worth of destroyed cloth = Rs. 20,000
A percentage is a number or ratio that can be expressed as a fraction of 100. It is denoted by the symbol %.
Percentage = Value/ Total value × 100%
Loss percentage = Loss/Total value × 100%
So, the loss percentage of cloth = 20,000/1,60,000 ×100%
= 0.125 × 100%
= 12.5%.

3x+4 < 4 pls some one help me pls it’s my last problem for my homework
Answer:
x < 0
Step-by-step explanation:
We are given this inequality:
3x + 4 < 4
And we want to solve it.
Solving inequalities is very similar to solving equations. We want to isolate the variable (in this case, x) on one side, while leaving the numbers on the other side.
To start, we can subtract 4 from both sides.
3x + 4 < 4
-4 -4
__________________
3x < 0
Now, we have the numbers on one side and the variable on the other, but we aren't done yet, as we want to solve for the value of x, or 1x, not the value of 3x.
So, we'll need to divide both sides by 3.

Jenna paid a total interest of $4810 (13% of the cost of the car) for the car.
What is APR?Suppose there is initial amount as P.
The interest, or say charge on it is applied annually as 'C' amount.
Taking how much percent of P is C, we get:
[tex]APR = \dfrac{C}{P} \times 100[/tex]
WE have been given that Jenna bought a new car for $37,000 and paid a 10% down payment and financed the remaining balance for 72 months with an APR of 6.5%
Assuming that she makes monthly payments, to determine the total interest Jenna pays over the life of the loan.
The cost = $37,000
Time = 72 months
APR = 6.5%
Then;
Interest = (37,000 x 6.5 x 2) /100
= $4810
Percentage of interest paid = (4810/37,000 ) x 100
= 13%
Therefore, Jenna paid a total interest of $4810 (13% of the cost of the car) for the car.

Jaquan passed a checkpoint jogging at a constant speed of 9 km/h. Then, 2 minutes later Odalis passed the same checkpoint.
If Odalis runs at a constant speed of 12 km/h, then how far past the checkpoint will Odalis be when they catch up to Jaquan?
The distance from the check point when Odalis catch up Jaquan is 1.2 kilometers.
What is relative speed ?Relative speed is the net speed difference when objects move in the same direction and sum of individual speeds when objects move in opposite direction.
Given Jaquan speed is 9km/hr which is 0.15km/minute and Odalis has a speed of 12km/hr which is 0.2km/minute.
∴ The relative speed difference between Jaquan and Odalis is
= (0.2 - 0.15) km/hr.
= 0.05 km/hr.
Given Odalis reached the check post after 2 minutes in this time Jaquan have covered (2×0.15) kilometers.
= 0.30 kilometers.
Now to catch up Jaquan, Odalis will need (0.30/0.05) minutes which is
= 6 minutes.
∴ The distance from the check post Odalis travelled to catch up with Jaquan is (0.2×6) kilometers.
= 1.2 kilometers.

write an equation in slope- intercept form for the line described.
perpendicular to y = 1/4x + 2 passes through (0,0)
Answer:
y=-4x+0
Step-by-step explanation:
Slope form is y=mx+b
m is the slope, and b is the y intercept. If the line must pass through (0,0) then the y intercept would be zero.
This give you y=mx+0
Now to find the slope you need a perpendicular line to the previous line. This would mean you have to swap 1/4 which is the previous lines slope.
1/4 is a positive so make it a negative, -1/4
Now flip -1/4 to make is -4/1 which also equals -4
Now with the slope -4 and y-intercept 0, you know you equation
