Answer:
The answer is below
Step-by-step explanation:
A linear graph has an equation in the form y = mx + b, where y and x are variables, m is the slope of the line and b is the y intercept (that is value of y at x = 0).
a) y represent the number of hours worked and x represent the number of weeks. The points are represented in the form (x, y).
First we can find the slope of the line by picking two points from the graph. Let us use (0, 0) and (2, 10). The slope m is given as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{10-0}{2-0} \\\\m=5[/tex]
The slope and constant of proportionality is 5.
b) The equation can be gotten using the points (0, 0) and (2, 10). Therefore:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-0=\frac{10-0}{2-0}(x-0)\\\\y=5x\\\\[/tex]
c) In 16 weeks (i.e. x = 16):
y = 5x
y = 5(16)
y = 80 hours

the graph for the equation y=2x+4 is shown below if another poisonous graph so that the system has one solution which equation could that be? y=2x-4 y=2(x+2) y=2(x-4( y=x+4)
Answer:
The graph below shows that y = x+4 has one solution the rest are all parallel.
Step-by-step explanation:
Answer:
y = x + 4
Intersects at (0,4).
Step-by-step explanation:
y = 2x -4: No solution(parallel)
y = 2(x+2): Infinite many solutions(same line)
y = 2(x-4): No solution(Also parallel)
y = x + 4: One Solution(Intersects at (0,4)).

The sum of these angles is 90 degrees
Answer:
30+30+30
Step-by-step explanation:
Help please please help me please please help please please ASAP please please help please please ASAP please please help
Answer:
the answer is 13 .
Step-by-step explanation:
it is a right angle which is 90 degrees, they already gave you 53 and 24 so you add those and get 77. then you subtract 77 from 90. that gives you 13!
Answer:
Start with: sin 53° = 24/w
Multiply both sides by w: w × (sin 53°) = 24
Divide both sides by "sin 53°": w = 24 / (sin 53°)
Calculate: w = 24 / 0.79863551
w = 30.1

1 meter of ribbon costs $3
how much do you pay for 2 3/4
If correct I will brainest u
Answer:
You pay $8 [tex]\frac{1}{4}[/tex] for 2 [tex]\frac{3}{4}[/tex] meters of ribbon
Step-by-step explanation:
Let us solve the question
∵ 1 meter of ribbon costs $3
∵ We need to find the cost of 2 [tex]\frac{3}{4}[/tex] meters
→ Separate the length of the ribbon to a whole number and a fraction
∵ The length of the ribbon = 2 m + [tex]\frac{3}{4}[/tex] m
→ Multiply each part by the cost of 1 meter
∵ The cost of 1 meter = 3 dollars
∴ The cost of the ribbon = 3 × 2 + 3 × [tex]\frac{3}{4}[/tex]
∴ The cost of the ribbon = 6 + [tex]\frac{9}{4}[/tex] dollars
→ Change the improper fraction [tex]\frac{9}{4}[/tex] to a mixed number
∵ 9 ÷ 4 = 2 [tex]\frac{1}{4}[/tex]
∴ The cost of the ribbon = 6 + 2 + [tex]\frac{1}{4}[/tex]
∴ The cost of the ribbon = 8 + [tex]\frac{1}{4}[/tex]
∴ The cost of the ribbon = 8 [tex]\frac{1}{4}[/tex] dollars
∴ You pay $8 [tex]\frac{1}{4}[/tex] for 2 [tex]\frac{3}{4}[/tex] meters of ribbon

What is algebra?Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.
Given:
[tex]9^{-1/2} = 27^{1/4}[/tex]÷[tex]3^{x +1}[/tex]
[tex][3^{2}]^{{-1/2}} = [(3)^{4}]^{1/4}[/tex] ÷[tex]3^{x +1}[/tex]
[tex]3^{-1}[/tex] = 3 ÷[tex]3^{x +1}[/tex]
[tex]3^{-1}[/tex]= [tex]\frac{3}{3^{x+1}}[/tex]
[tex]3^{-1}= 3^{1-x+1}[/tex]
[tex]3^{-1}= 3^{2-x}[/tex]
On comparing we get,
-1=2-x
x= 3
Hence, the value of x is 3.

Complete the table for each given sequence: On = 15+3(n − 1)
Answer:
The complete table will be:
Term # Value of aₙ
1 15
5 27
10 42
20 72
Step-by-step explanation:
Given the sequence expression
aₙ = 15 + 3(n-1)
Substituting n = 1 for the first term
aₙ = 15 + 3(n-1)
a₁ = 15 + 3(1-1)
a₁ = 15 + 3(0)
a₁ = 15 + 0
a₁ = 15
Substituting n = 5 for the 5th term
aₙ = 15 + 3(n-1)
a₅ = 15 + 3(5-1)
a₅ = 15 + 3(4)
a₅ = 15 + 12
a₅ = 27
Substituting n = 10 for the 10th term
aₙ = 15 + 3(n-1)
a₁₀ = 15 + 3(10-1)
a₁₀ = 15 + 3(9)
a₁₀ = 15 + 27
a₁₀ = 42
Substituting n = 20 for the 20th term
aₙ = 15 + 3(n-1)
a₂₀ = 15 + 3(20-1)
a₂₀ = 15 + 3(19)
a₂₀ = 15 + 57
a₂₀ = 72
Therefore, the complete table will be:

Colin buys a car for £20000. It depreciates at a rate of 6% per year. How much will it be worth in 2 years? Give your answer to the nearest penny where appropriate.
The worth of the car in 2 years is £1767.2
How to determine the worth of the car?
The given parameters are:
Value, a = £20000
Depreciation rate, r = 6%
The value of the car in t years is represented as:
f(t) = a *(1 - r)^t
This gives
f(t) = 2000 * (1 - 6%)^t
In 2 years, t = 2
So, we have:
f(2) = 2000 * (1 - 6%)^2
Evaluate
f(2) = 1767.2
Hence, the worth of the car in 2 years is £1767.2
