Step-by-step explanation:
f(0)=8
Coordinate: (0,8)
y intercept,c: 8
f(4)=20
Coordinate: (4,20)
gradient, m
= (20-8)/(4-0)
=3
Y=mx+c
f(x)=3x+8
f(x)=3x+8 is the linear function f with the values f(0) = 8 and f(4) = 20.
What is Linear Function?A linear function is a function that represents a straight line on the coordinate plane.
The given functions are f(0)=8 and f(4) =20
For f(0)=8
Coordinate: (0,8)
y intercept, c: 8
For f(4)=20
Coordinate: (4,20)
gradient or slope, m when x₁=0,y₁=8,x₂=4, y₂=20
=( y₂-y₁)/(x₂-x₁)
= (20-8)/(4-0)=12/4
=3
The linear equation is in the form, y=mx+c
So f(x)=3x+8, where 3 is the slope and 8 is y intercept.

Answer: 120.
Step-by-step explanation: the angles of a triangle add up to 180 degrees. angles c and d are given and their values add up to 120 degrees. so E must be 180-120, which equals 60 degrees. We also know that a straight line is 180 degrees and since one side is 60 degrees, the other one must add up with 60 to give 180, which is 120.
Graph a right triangle with the two points forming the hypotenuse.
Using the sides, find the distance between the two points in simplest
radical form. (8,7) and (6,3)
the distance between the points (8, 7) and (6, 3) which is the hypotenuse of the triangle is 2 √ 5 units.
We need to find the distance between two points which is the hypotenuse of the triangle:
(8, 7) and (6, 3)
It can be calculated using distance formula:
D = √ (x₂ - x₁)² + (y₂ - y₁)²
Substituting the values in the formula, we get that:
D = √ (6 - 8)² + (3 - 7)²
D = √ ( - 2 )² + ( - 4 )²
D = √ 4 + 16
D = √ 20
D = 2 √ 5 units
Therefore, we get that, the distance between the points (8, 7) and (6, 3) which is the hypotenuse of the triangle is 2 √ 5 units.

Six times a number is at least four less than eight times the number. If x represents the number, which will help find
the number?
Answer:
The inequation 6x ≥ 8x - 4 can be used to find the solution.
The solution is x ≤ 2
Step-by-step explanation:
In math, 'at least' represents greater or equal than (which is the inequation simbol ≥)
If x represents the number then six times a number is the multiplication of x by 6, and four less than eight times the number can be written as: 8x -4
6x ≥ 8x - 4
Solving the inequation;
Substracting 6x each side:
0 ≥ 8x - 6x -4
Suming 4 each side
4 ≥ 2x
Dividing by 2 each side
2 ≥ x
2 greater or equal than x is the same as:
x ≤ 2

Anil Kumar took a loan of Rs. 20,000 from bank at the rate of 8% per annum. At the end of 2 years, how much compound amount should he pay if the interest was compounding half-yearly?
Anil Kumar should pay a compound amount of Rs. 23,397.12 at the end of 2 years.
Compound interest is a method of calculating interest where the interest earned is added to the principal amount, and the resulting sum becomes the new principal for the next period's interest calculation. This process is repeated until the end of the investment period.
The formula to calculate the compound interest is:
[tex]A = P(1 + r/n)^(^n^t^)[/tex]
Where,
A = Amount after the given time
P = Principal amount (initial investment)
r = Annual interest rate (as a decimal)
n = Number of times the interest is compounded per year
t = Time duration for which the interest is calculated (in years)
In this case, Anil Kumar took a loan of Rs. 20,000 from a bank at the rate of 8% per annum, compounded half-yearly, for 2 years. Therefore, we can plug in the values as follows:
P = Rs. 20,000
r = 8% per annum = 0.08 (as a decimal)
n = 2 (since the interest is compounded half-yearly)
t = 2 years
Now, we can calculate the compound amount using the above formula:
[tex]A = P(1 + r/n)^(^n^t^)[/tex]
[tex]A = 20,000(1 + 0.08/2)^(^4^)[/tex]
[tex]A = 20,000(1 + 0.04)^4[/tex]
[tex]A = 20,000(1.04)^4[/tex]
[tex]A = 23397.1712[/tex]
Therefore, Anil Kumar should pay a compound amount of Rs. 23,397.123 at the end of 2 years.

Answer:
x = 6[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 12² = 18²
x² + 144 = 324 ( subtract 144 from both sides )
x² = 180 ( take the square root of both sides )
x = [tex]\sqrt{180}[/tex]
= [tex]\sqrt{36(5)}[/tex]
= [tex]\sqrt{36}[/tex] × [tex]\sqrt{5}[/tex]
= 6[tex]\sqrt{5}[/tex] ← exact value
You have $50 in your bank account. Each week you plan to deposit $6 from your allowance and $20 from your paycheck. The equation b = 60 + (20+6)w gives the amount b in your account after w weeks. How many weeks from now will you have $215 in your bank account?
6 weeks from now, you will have $215 in your bank account
How many weeks from now will you have $215 in your bank account?The given parameters are:
b = 60 + (20+6)w
When the account balance is $215, we have
60 + (20+6)w = 215
Subtract 60 from both sides
(20+6)w = 155
This gives
26w = 155
Divide both sides by 26
w = 5.96
Approximate
w = 6
Hence, 6 weeks from now, you will have $215 in your bank account

Help me find the X! UwU..
Well all the angles in a triangle add up too 180º and this triangle is obviously a equilateral triangle (all sides are same) BUT as you see the other people saying X = 60º notice that it says 2 xº meaning that it is X x 2 so 60º is actually wrong :).
If it is X is 60º (since the 3 angles add together since it’s equilateral) then that would be 2 x 60º = 120º times 3 WHICH IS NOT 180.I think U get what I mean now,it’s 2 Xº; so X is 30 because 30 x 2 = 60º and 60 x 3 = 180º!
So Da Answer is X = 30º

What’s the value of k ?
Hello!
[tex]\large\boxed{k = 10^{o}}[/tex]
When given two interior angles and an exterior angle, the sum of the two interior angles is equal to the sum of the exterior angle. Therefore:
m∠YZX + m∠ZXY ≅ m∠MYZ
(4k + 5)° + (6k + 10)° = 115°
Combine like terms:
10k + 15 = 115°
Subtract 15 from both sides:
10k = 100°
Divide both sides by 10:
k = 10°
Answer:
k=10
Step-by-step explanation:
First you would find the missing angle at the top this would be 65 degrees, this means that the 2 other missing angles must total to 115 degrees.
Second you would set the equations equal to 115
4k+5+6k+10=115
Then you would combine the like terms
10k+15=115
next you would subtract the 15 from both sides
10k=100
then you divide by 10
k=10

It will take you 10 hours to paint your garage
it will take your brother 15 hours to paint your garage.
How long will it take to paint the garage if the two of you paint together
Total work = LCM of 10 and 15 = 30 units
now , it will take 10 hours to paint the garage
therefore it one hour efficiency = 30/10 =3 units
similarly your brother take 15 hours to apint the garage
therefore brother one hour efficiency = 30/15 = 2 units
so total one hour efficiency is 5 units
and total work is 30 units and their one hour efficiency is 5 units
therefore they complete the work in 30 /5 = 6 hour
Hence they take 6 hours to paint the garage if the two of you paint together.

3x - 12 = 5x - 6 ( subtract 5x from both sides )
