Answer:
Slope: 1
Y-Intercept: (0,4)
Equation: y=1x+4
Step-by-step explanation:
To solve for slope you need to pick 2 points on the graph (ex. 2,6 and 4,8 ), then you use the formula to find the slope.
For Y-Intercept you just look for where the line intercepts on the y-axis (ex. 0,4).
If the line doesn't touch the origin (0,0), then it isn't proportional.
For the equation it's y=mx+b or, if its proportional then y=mx. The Y-Intercept will always be b. The slope represents m. The x is the variable.

Answers
Answer:
1/2
0.5
50%
Step-by-step explanation:
The square is spilt into 2 equal pieces, one out of the 2 is shaded therefore 1/2 is shaded. The decimal to represent the shaded area would be 0.5, as 1 times 1/2 = 0.5. As a percent the shaded area represents 50% as 1/2 times 100 (per cent = per hundred) is equivalent to 50.

Divide using synthetic division (x^2 +9)÷(x-3) =
Answers
Answer: x+3+ 18/x-3
Step-by-step explanation:
The complete division problem can be written as:
(x² + 9) / (x-3) = x + 3 + 18/(x-3)
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
To divide using synthetic division, we follow these steps:
Write the dividend (x² +9) and the divisor (x-3) in the form of a long division problem, with the divisor (x-3) written on the outside and the dividend (x² +9) written inside the division brackets.
Write the coefficient of the first term of the dividend (in this case, 1) in the first row of the synthetic division. This will be the first term of the quotient.
Multiply the divisor (x-3) by the coefficient in the first row (1), and write the result (x-3) in the second row.
Add the second term of the dividend (9) to the result in the second row. The result is the coefficient of the second term of the quotient.
Repeat this process until you have found the coefficients of all the terms in the quotient.
Using this process, we can divide (x² +9) by (x-3) as follows:
The quotient is x + 3. The remainder is 18, so the complete division problem can be written as:
(x² + 9) / (x-3) = x + 3 + 18/(x-3)

Write an equation to determine the initial number of orange trees (t)(t)left parenthesis, t, right parenthesis on MacDonald's farm.
Find the initial number of orange trees on MacDonald's farm.
orange trees
Answers
Answer:Initial number of trees (t)=204
Step-by-step explanation:
t = initial number of trees
Subtract 5 trees from the initial number of trees
we have,
t-5
each remaining tree made 210 oranges for a total of 41,790 oranges
We have,
(t-5) * 210=41790
Solve the equation
(t-5) * 210=41790
Open the bracket
210t-1050=41790
210t=41790+1050
210t=42840
Divide both sides by 210
210t/210=42840/210
t=204
The initial number of trees on MacDonald farm orange trees (t)=204
If 5 is removed from the initial trees
t-5=204-5
=199 trees
199 trees produce 210 oranges
We have,
199*210=41790 oranges
5. James makes $15.50 per hour and works 40 hours a week. He pays 26% of his gross earnings in federal and state
taxes. He also saves 7.5% of his monthly gross income to put into savings. He is considering renting an apartment tha
will cost $1,400 per month. Based on his expenses, can he make the monthly payments?
Answers
9514 1404 393
Answer:
no
Step-by-step explanation:
On average, there are about 173 1/3 hours per month, so James's take-home pay will be about ...
($15.50/h)(173 1/3 h/mo)(1 -26%) = $1988.13
His proposed rental is about ...
1400/1988.13 · 100% = 70.4%
of his take-home pay.
Most financial planners would recommend the percentage be well below 50%. It is unlikely James can make his proposed monthly payments.

Anyone can help me with math for solving for a side in the right triangles for khan academy
Answers
Answer:
7.45
Step-by-step explanation:
We are given a right triangle with one side length known and an angle know so we can use some trigonometry.
You need to find the hypotenuse so you are going to use either sine or cosine.
Since the adjacent from the angle is given (SOH-CAH-TOA) we can use cosine so,
cos(20) = 7/h
=>h = 7/cos(20)
=> 7.44924
=> 7.45

Hope it helps! Good luck friend! :3
Answer:
36 / (9 - 3) = 6

If you put the parentheses around 9 - 3, that will give you 6. 36 divided by 6 = 6. Also, in PEMDAS, Parentheses comes first, so that is why the parentheses go there to make this true.
Colin invests £2350 into a savings account. The bank gives 4.2% compound interest for the first 4 years and 4.9% thereafter. How much will Colin have after 10 years to the nearest pound?
Answers
Answer:
£3,692
Step-by-step explanation:
First four years
A = p(1 + r/n)^nt
P = £2350
r = 4.2% = 0.042
n = 1
t = 4
A = p(1 + r/n)^nt
= 2350(1 + 0.042/1)^1*4
= 2350(1 + 0.042)^4
= 2350(1.042)^4
= 2350(1.5789)
= 2770.42
A = £2770.42
Next 6 years
P = £2770.42
r = 4.9% = 0.049
n = 1
t = 6
A = p(1 + r/n)^nt
= 2770.42(1 + 0.049/1)^1*6
= 2770.42(1 + 0.049)^6
= 2770.42(1.049)^6
= 2770.42(1.3325)
= 3691.59
A = £3691.59
Approximately £3692
