3: -9
4: -49
Answer:
See screenshot below
Step-by-step explanation:
All you have to do it substitute the x in the rule with the x in the table. Let's do the first one in the steps below.Write the equation with the x value: y = -10(-1) + 1-10 × -1 = 10Plug 10 in: y = 10 + 110 + 1 = 11So, y = 11Now that you know how to find the rest, go ahead and do it (my answer doesn't show the work, but the answers are in the screenshot below)I hope this helps!

Express the shaded area as a fraction, a decimal, and a percent of the whole.
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) =
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)

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?
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.

Sam finished his math assignment in 1/4 hours then he completed his English assignment in 2/5 hours. How many hours did Sam spent doing both assignments?
Answer:
13/20 Hours
Step-by-step explanation:
you have to find a common denominator. (20) You do 4x5 and 5x4 both equal 20. Then you do 1x5=5 and 2x4=8 then 8+5=13 then you make your fraction which is 13/20.

True or False. Shapes that have at least one right angle also have at least one pair of perpendicular lines. Explain your thinking.
Answer:
True
Step-by-step explanation:
In geometry, the property of being perpendicular is the relationship between two lines which meet at a right angle.

Add parentheses to make true 36 / 9 - 3 = 6
36/ (9 - 3) = 6
Cause:
9 - 3 = 6
Then:
36/6 simplified equals 6
So, your answer is 36/(9 - 3) = 6
Hope it helps! Good luck friend! :3
Answer:
36 / (9 - 3) = 6
Step-by-step explanation:
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.
Find the value of each variable. Write answers in simplest radical form.
Answer:
1) x = 5
2) y = 5·√2
Step-by-step explanation:
1) The given parameter of the right triangle are;
The legs of the right triangle = 'x', and 5
One interior angle of the right triangle = 45°
Therefore, buy the interior angle summation property of a right triangle, we have;
The measure of the other angle, θ = 180° - 90° - 45° = 45°
From which we have;
A right triangle with an interior angle of 45° is an isosceles triangle with both legs equal
∴ The length of the other leg, x = 5
x = 5
2) By Pythagoras's theorem, we have that the square of the length of the hypotenuse, 'y', is given as follows;
y² = x² + 5²
∴ y² = 5² + 5²
y = √(5² + 5²) = √(25 + 25) = √50 = √(25 ×2) = 5·√2
y = 5·√2 in the simplest radical form.
Anyone can help me with math for solving for a side in the right triangles for khan academy
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
t the beginning of the season, MacDonald had to remove 555 orange trees from his farm. Each of the remaining trees produced 210210210 oranges for a total harvest of 417904179041790 oranges.
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
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

I need help with my math assignment
Answer:
y = 3x + 11
Step-by-step explanation:
obviously since y is 11 when x is zero the constant term is 11.
Then use the other coordinates to find the cooefficent of x.
-4= c × -5 + 11
-4= -5c + 11
5c=15, c=3
Therefore the equation should be:
y= 3x + 11
