Point K is on line segment \overline{JL} JL . Given JK=2x-2,JK=2x−2, KL=x-9,KL=x−9, and JL=2x+8,JL=2x+8, determine the numerical length of \overline{KL}. KL .
Answer:
KL = 10
Step-by-step explanation:
Point K is on line segment \overline{JL} JL . Given
JK=2x−2
JL=2x+8
KL=x-9
JL = JK + KL
Hence:
2x + 8 = 2x - 2 + x - 9
2x + 8 = 2x + x - 2 -9
2x + 8 = 3x - 11
Collect like terms
3x - 2x = 8 + 11
x = 19
We are to find the numerical length of KL
KL = x - 9
KL = 19 - 9
KL = 10
(-3, 11) a solution to the systems of equations: x – 3y = -36 and 3x + 4y = 48
true or false
Answer:
TRUE and FALSE (please look at step-by-step)
Step-by-step explanation:
How to know if it's true or false, you just simply plug in the given numbers to the x and y values.
x = -3
y = 11
for the x - 3y = -36 equation:
-3 -3(11) = -36
-3 - 33 = -36
This equation is true.
for the 3x + 4y = 48 equation:
3(-3) + 4(11) = 48
-9 + 44 = 35
This equation is false.

Step-by-step explanation:
adding both equations and then we find the value of y which is given below
y = -2/3x
and then putting the value of y in any above equation then we find the value of X which is given below
X = 1
In a grid of an auditorium, the vertices of a section of seats are A(40, 20) , B(80, 20) , C(100, 70) , and D(40, 70) . The coordinates are measured in feet. Find the area of the section.
Answer:
[tex]Area = 2900[/tex]
Step-by-step explanation:
Given
[tex]A (x_1,y_1) = (40,20)[/tex]
[tex]B (x_2,y_2) = (80,20)[/tex]
[tex]C (x_3,y_3) = (100,70)[/tex]
[tex]D (x_4,y_4) = (40,70)[/tex]
Required
Determine the Area
The area of the section is:
[tex]Area = \frac{1}{2}|(x_1y_2 + x_2y_3 + x_3y_4 + x_4y_1) - (y_1x_2 + y_2x_3 + y_3x_4 + y_4x_1)|[/tex]
Substitute values for the x's and y's
[tex]Area = \frac{1}{2}|(40 * 20 + 80*70 + 100*70 + 40*40) - (20*80 + 20*100 + 70*40 + 70*40)|[/tex]
[tex]Area = \frac{1}{2}|15000 - 9200|[/tex]
[tex]Area = \frac{1}{2}|5800|[/tex]
[tex]Area = \frac{1}{2} * 5800[/tex]
[tex]Area = 2900[/tex]
Hence, the area of the section is 2900ft^2
Paulo catches a 7.45 am tram to school. During a period of 79 days, he arrives at school on time 53 occasions. Estimate the probability Paulo:
arrives on time: arrives late:
Answer:
On time: 0.67
Late: 0.33
Step-by-step explanation:
Probabilities
One approach to estimating the probability of occurrence of an event is to record the number of times that event happens (e) and compare it with the total number of trials (n).
The probability can be estimated with the formula:
[tex]\displaystyle P=\frac{e}{n}[/tex]
And the probability that the event doesn't occur is
Q = 1 - P
Paulo arrives on time to school e=53 times out of n=79 times. The probability that he arrives on time is:
[tex]\displaystyle P=\frac{53}{79}[/tex]
P = 0.67
And the probability he arrives late is:
Q = 1 - 0.67 = 0.33

[Find all the missing side and angles of this triangle]
Step-by-step explanation:
We have AB = 7, Angle ABC = 70°
and Angle ACB = 90°.
Angle BAC = 180° - 70° - 90° = 20°
(Sum of angles in a triangle = 180°)
Using Trignometry,
AC = 7sin70° = 6.58.
BC = 7cos70° = 2.39.
Can someone pls help me? This is urgent :(
Answer:
They are both congruent triangles because they both have the same height, base length, and the same angle.

Two snakes race the speed of the first is 24 1/2 inches per minute and the speed of the other is 26 inches per minute how far apart with they be in 3 min? 10 min?
Answer:
In 3 min = 4 1/2
10 min = 15
If you multiply both of the snakes speed by the specific amount of minutes and then subtract both of the sums you'll get the answer :)

Answer: x = 15
Step-by-step explanation:
same thing. here's my work:
4x - 5 = 3x + 10
4x - 5 (+ 5) = 3x + 10 (+ 5)
4x = 3x + 15
4x (- 3x) = 3x (- 3x) + 15
x = 15

Write the equation of the line pleaseeee
Answer:
y = 2/3x -1
Step-by-step explanation:
y intersect is -1 as that's where the line passes the y axis
the slope can be found by finding two points and using the slope formula (y-y)/(x-x)
What is the equation of the line that passes through (4,3) and (2, -1)?
y = 6x+4
y = 1/2 x -2
y = 2x-5
y = 4x -13
c
you need to find the slope and then y intercept
m=y2-y1/x2-x1
so m=2
now y intercept
3=2(4)+b
solve for b
u get -5
therefore
y=2x-5
A function represented by the equation y=1/3x + 4 is a graph on a coordinate plane. What will happen to the line if the slope is changed to 2/3?
Answer:
Graph of the new function will be vertically stretched by 2 units.
Step-by-step explanation:
A linear function is represented by the equation, y = [tex]\frac{1}{3}x+ 4[/tex]
This function has the slope = [tex]\frac{1}{3}[/tex] and y-intercept = 4
If this function is stretched vertically by 'k' the the equation of the new function will be,
y = [tex]a(\frac{1}{3})x+ 4[/tex]
y = [tex]\frac{a}{3}x+4[/tex] ---------(1)
If the slope of this equation is changed to [tex]\frac{2}{3}[/tex],
New equation of the function will be,
y = [tex]\frac{2}{3}x+4[/tex] ---------(2)
Comparing equations (1) and (2),
a = 2
Therefore, graph of the new function will be stretched vertically by 2 units.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first number be A
Now , the value of A is = 16 cm
Let the second number be = B
The value of B is = 20 cm
The ratio of A and B is calculated as C
where C = A / B
A goes to the numerator of the fraction and B to the denominator
Substituting the values in the equation , we get
C = A/B
C = 16/20

Factorise
121ײ + 110 +25 y²
Answer:
(5y+11)²
Step-by-step explanation:
The given expression is :
25y²+110y+121
We need to factors of the given expression.
We know that, (11)² = 121
5² = 25
We can write the given expression as :
25y²+110y+121 = (5y)² + 2(5y)(11) +11²
Using identity : (a+b)² = a²+2ab+b²
25y²+110y+121 = (5y+11)²
Hence, the factors of 25y²+110y+121 is (5y+11)².
The lengths of the sides of a triangle are in the extended ratio 6 : 7 : 10. The perimeter of the triangle is 92 cm. What are the lengths of the sides?
Step-by-step explanation:
[tex] \underline{ \underline{ \text{Given}}} : [/tex]
The ratios of length : 6 : 7 : 10Perimeter of a triangle = 92 cmLet the lengths of a triangle be 6x , 7x and 10x.
[tex] \underline{ \underline{ \text{To \: find}}} : [/tex]
Lengths of the side[tex] \underline{ \boxed{ \text{Sum \: of \: all \: sides \: of \: triangle = Perimeter \: of \: a \: triangle}}}[/tex]
⟹ [tex] \sf{6x + 7x + 10 = 92}[/tex]
Solve for x
⟹ [tex] \sf{23x = 92}[/tex]
⟹ [tex] \sf{ \frac{23x}{23} = \frac{92}{23}} [/tex]
⟹ [tex] \sf{x = 4}[/tex] cm
Now , Replacing the value of x :
⟼ [tex] \sf{6x = 6 \times4 = 24}[/tex] cm
⟼ [tex] \sf{7x = 7 \times 4 = 28}[/tex] cm
⟼ [tex] \sf{10x = 10 \times 4 = 40}[/tex] cm
Hence , the sides of the triangle are 24 cm , 28 cm and 40 cm.
