Answer:
C. JK and LM are congruent
Step-by-step explanation:
Given the coordinates J(-2,8), K(0,8), L(1,0), and M(1,-2), in other to determine whether JK is congruent to LM, we need to determine if the length of side JK and LM are equal i.e JK = LM
To get JK:
We will find the distance between the coordinates J(-2,8), K(0,8) to get the length JK using the formula:
JK =√(x2-x1)²+(y2-y1)²
JK = √(0-(-2))²+(8-8)²
JK = √2²+0²
JK = √4
JK = 2
For the length of LM with coordinate L(1,0), and M(1,-2)
LM = √(1-1)²+(-2-0)²
LM = √0²+(-2)²
LM = √0²+2²
LM = √0+4
LM =√4
LM = 2
Since JK = LM = 2 units, this means that JK and LM are congruent.

Prove that in a triangle the length of any altitude is smaller than the sides that are meeting at the altitude's vertex.
The proof here would be based on the use of the Pythagoras theorem in trigonometry.
How to prove that the length of the altitude are smallerIn a triangle getting the altitude or height will result to producing a right angled triangle. In trigonometry, a right angled triangle have the sides as the hypotenuse, the adjacent and the opposite. in this case the altitude is either the opposite or adjacent.
From Pythagoras Theorem, the hypotenuse. equals the square root of the sum of squares of the other two sides. hence is the longer side. Each leg of this triangle would be shorter than the hypotenuse. The two sides that meet at the vertex are the adjacent or the opposite and the hypotenuse.

1. Write the equation of a line parallel to y = -2x + 10 that passes through point (2, 4).
Answer:
y - 4= -2(x - 2)
Step-by-step explanation:
(This answer is in point slope form, if you need the answer in a different form like slope intercept, you would have to distribute the negative 2 and bring the negative 4 to the right side.)
So, you know the line is parallel to the equation y= -2x + 10. We know that parallel lines must have the same slope, so the answer will have a slope of negative 2. Because they have given you a point that the line passes through, we are going to put the answer in point slope form. we know a point and we know the slope, hence it is called point-slope.
Point slope form is y - y₁ = m(x - x₁). The m stands for the slope, and the x₁ and y₁ is where you will plug in the x and y coordinates (2,4) .
So to plug in the numbers into point slope form it would be y - 4 = -2 (x - 2). hope this helped :)
If a +5 = b + 3 and a + 5 = 12, then b +3=
Answer:
12
Step-by-step explanation:
The Transitive Property states that if one quantity equals a second quantity, and the second quantity equals a third quantity, then the first quantity equals the third quantity.
Using Transitive Property, it is found that b + 3 is equal to 12.
What is Transitive Property ?The Transitive Property states that if one quantity equals a second quantity, and the second quantity equals a third quantity, then the first quantity equals the third quantity.
Given;
If a +5 = b + 3 and a + 5 = 12, then we need to find b +3=

Hans is using frequent flier miles to fly to a location 750 miles away, but the airline he is using still charges $20.19 for fees and taxes and $0.15 to redeem each mile. In the equation below, x represents the distance Hans is flying, and y represents the cost of the trip. Y = $0.15x + $20.19 How much did Hans pay for his trip?
Answer:
Cost of the trip = $132.69
Step-by-step explanation:
Given:
Total distance = 750 mile
Fixed charge = $20.19
Variable charges = $0.15 per mile
Find:
Cost of the trip
Computation:
Y = $0.15x + $20.19
Y = $0.15(750) + $20.19
Y = $132.69
Cost of the trip = $132.69

Katherine invests $7770 in a six-month money market account giving 5.8% simple annual interest and $12,500 in a
three-year CD giving 7 25% simple annual interest. Assuming that Katherine does not reinvest or renew these
investments, how much money will she have when both investments reach maturity, to the nearest dollar?
$2,944
b. $15,219
$23,214
d. $30,886
a
С.
Answer:
Katherine will receive $23214 to the nearest dollar from both investments.
Step-by-step explanation:
Simple interest = Principal × Time × rate
Le's work out the interest Katherine earns from the two investments.
Money Market Account
Simple interest = 7770 × 5.8/100 × 6/12
= 7770 × 0.058 × 0.5 = $225.33
So, the amount she gets at maturity is:
$7770 + $225.33= $7995.33
CD account
Simple interest = 12500 × 0.0725 × 3 = $2718.75
The amount she receives at the end of period is:
$12500 + $2718.75 = $15218.75
The total amount she receives from both investments at maturity is:
$15218.75 + $7995.33 = $23214.08
This to the nearest dollar is:
= $23214

Jessica prepared 36 kilograms of dough after working 6 hours. How much dough did Jessica prepare if she worked for 8 hours? Assume the relationship is directly proportional.
Answer:
48
Step-by-step explanation:
because 36 divided by 6 is 6 and that is how much dough she produces in an hour so if you added two more 6s to 6 to make it 8 meaning you are adding 12 because that is how much dough she makes in an hour
Devon purchased a new car valued at $16,000 that depreciated continuously at a rate of 35%. Its current value is $2,000. The equation represents the situation, where t is the age of the car in years and r is the rate of depreciation. About how old is Devon's car? Use a calculator and round your answer to the nearest whole number.
Given :
Devon purchased a new car valued at $16,000 that depreciated continuously at a rate of 35%.
Its current value is $2,000.
To Find :
Age of car.
Solution :
Price of car after 1 year :
[tex]P_1=P_o(1-0.35)[/tex]
Price of car after 2 year :
[tex]P_2=P_1(1-0.35)\\\\P_2=[P_o(1-0.35)](1-0.35)\\\\P_2=P_o(1-0.35)^2[/tex]
So, price of car after n years.
[tex]P_n=P_o(1-0.35)^n[/tex]
[tex]2000=16000(1-0.35)^n\\\\0.65^n=0.125\\\\n\times log(0.56)=log(0.125)\\\\n=\dfrac{log(0.125)}{log(0.56)}\\\\n=3.58[/tex]
Therefore, age of car in nearest whole number is 4 years.
Hence, this is the required solution.

Which table could represent a function?
1. 1:4,2:2, 3:4, 2:6
2. 1:2, 2:4, 3:6, 4:2
3. 2:6, 0:4, 1:6, 2:2
4. 2:2, 3:2, 4:6, 3:6
The table that represents a function is 1:2, 2:4, 3:6, 4:2.
Option 2 is the correct answer.
Given,
Function table:
1. 1 → 4, 2 → 2, 3 → 4, 2 → 6
2. 1 → 2, 2 → 4, 3 → 6, 4 → 2
3. 2 → 6, 0 → 4, 1 → 6, 2 → 2
4. 2 → 2, 3 → 2, 4 → 6, 3 → 6
We need to find which one is a function.
What is a function?A function has an input and an output.
We can have different inputs and the same output.
Example:
f(x) = x²
x = 1, -1 are the inputs
f(1) = 1
f(-1) = 1
- We see that we have the same output 1 with different inputs 1 and -1.
i.e Many to one
- But we can not have the same inputs and different outputs.
i.e One to many
- We can have one-to-one in a given function.
We have,
1. 1 → 4, 2 → 2, 3 → 4, 2 → 6
Here,
2 → 2 and 2 → 6 = one to many.
We have the same inputs but different outputs which is not possible.
It is not a function.
2. 1 → 2, 2 → 4, 3 → 6, 4 → 2
Here,
1 → 2 and 4 → 2 = many to one
2 → 4 and 3 → 6 = one to one
It is a function.
3. 2 → 6, 0 → 4, 1 → 6, 2 → 2
2 → 6 and 2 → 2 = one to many
This is not possible.
It is not a function.
4. 2 → 2, 3 → 2, 4 → 6, 3 → 6
3 → 2 and 3 → 6 = one to many
This is not possible.
It is not a function.
Thus the table that represents a function is 1:2, 2:4, 3:6, 4:2.
Option 2 is the correct answer.
