Answer:
9-5[x+4] = 16 , 3[2-x] = 3
Step-by-step explanation:
The mathematical model C(x) = 500x + 100,000 represents the cost in dollars a company has in manufacturing x items during a month. Based on this, how many items were produced if expenses were $250,000 in one month?
Answer:
300
Step-by-step explanation:
Fill in the given value and solve for x.
C(x) = 500x +100000
250000 = 500x +100000
500 = x + 200 . . . . . . divide by 500
300 = x
300 items were produced if the month's expenses were $250,000.

Write the equation of the line fully simplified slope-intercept form.
Answer:
y=-x+2
Step-by-step explanation:
The slope-intercept form is y=mx+b where m is the slope and b is the y-intercept.
From the graph, we can see that the y-intercept is at (0,2) so the equation becomes y=mx+2.
Other points on the graph include (1,1) and (2,0). Plugging (1,1) into the slope-intercept equation, we get 1=(m)1+2. Solving this will give us m=-1.
We can confirm this by plugging m=-1 into the equation along with the point (2,0); 0=(-1*2)+2. It checks out!
So our final equation in slope-intercept form will be y=-x+2
Answer: Think it is y=2x+2
Step-by-step explanation: because whats your y intercept it is on the two. Whats your x intercept it is also on the a 2.

A family paid $30600 as a down payment for a home. If this represents %17 of the price of the home, find the price of the home
Answer:
180000
Step-by-step explanation:
30600/17=1800
1800•100=180000
Answer:
$180,000
Step-by-step explanation:
First you have to change 17% into a decimal which would be 0.17 which makes it easier to work with.
If we put this into an equation we know some value of x is the original price of the house and 0.17 (17%) of this unknown x is 30600.
Therefore: x * 0.17 = 30600
We divide 0.17 on both sides to cancel it on the left and get x by itself.
Now x = 30600/0.17
We get x = $180,000
Therefore, the original price of the home was $180,000.

Oscar has received a $4,000 gift and is looking for a bank to start a savings account. Which option would be the best for him at a current inflation rate of 1.5%?
Here is the complete question
A nominal interest rate of 5%
A real interest rate of 5%
A real interest rate of 3%
A nominal interest rate of 3%
Answer:
A real interest rate of 5%
Step-by-step explanation:
A real interest rate of 5% is the best option for oscar. The nominal rate of interest is a type of interest rate that shows the increase in in percentage of money without the depreciation discount that is usually caused by inflation or the payment of tax.
The real rate of interest shows the real increase in the money that has been paid for an investment. This is after inflation has been discounted and all forms of taxes have been paid.
So oscar should invest his $4000 on a savings account whose real interest rate is 5% per year

Answer:
50⁰
Step-by-step explanation:
Add 130 plus 50 to get 180.
Answer:
x = 50°
Step-by-step explanation:
In a parallelogram consecutive angles are supplementary, thus
∠ BAC + ∠ ABD = 180°, that is
130° + ∠ ABD = 180° ( subtract 130° from both sides )
∠ ABD = 50°
Since ACDB and FGHE are congruent then corresponding angles are congruent, thus
∠ FEH = ∠ ABD = 50° =x

Answer: y = 4x - 16
Step-by-step explanation:
Using the point slope formula to plug in your point and slope, I found
y - 4 = 4 (x - 5)
After simplifying it into an equation of the line I got y = 4x - 16

Step-by-step explanation:
intergers are numbers that are not a fraction.ie a whole number.
A rectangular lot is 140 meters long and 100 meters wide. Give the length and width of another rectangular lot that has the same perimeter but a larger area.
Step-by-step explanation:
Length of rectangle is 140 m and its breadth is 100 m
Perimeter = sum of all sides
For rectangle, P = 2(l+b)
P = 2(140+100)
P = 480 m
Area = length × breadth
For a rectangle, A = lb
A = 140 × 100
A = 14000 m²
We need to write the length and breadth such that it has the same perimeter but a larger area.
Let the length is 110 m and breadth is 130 m.
Perimeter, P = 2(110+130)
P = 480 m
Perimeter is same as previous
Area, A = 110 × 130
A = 14300 m²
Area is more than the initial area.
Hence, this is the required solution.
answer:
it's [tex]\boxed{L=130, \W=110}[/tex]
explanation:
[tex]\boxed{L=140}\\\boxed{W=100}\\P=2(L+W)\\P=2(140+100)\\\boxed{P=480m}\\A=L*W\\A=140*100\\\boxed{A=14000m^{2}}[/tex]
It's easy to get a Length and Width with an equal Perimeter as this rectangle, how? the key is in the Perimeter formula for rectangle, it is literally 2 times the sum of the Length and Width, so [tex]2(L+W)=2(sum)[/tex], that means we can change the value of both the Width and the Length as long as the sum of both the Length and the Width is equal;
[tex]\boxed{L=140}\\\boxed{W=100}\\L+W=140+100=\boxed{240}[/tex]
to change these values and still have a perimeter equal to 480 meters, and an area larger than 14,000 meters square, we gotta have a length and a width that have a sum of 240 and still maintain a hundred place value, for example 130 and 110, not 150 and 90, because [tex]150*90=13500[/tex] which is less than our goal; while [tex]130*110=14300[/tex], note that as long as one of the values doesn't fall below 100 you're solid.

Solve for b:
6b+14 = -7-b
Answer:
b = -3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6b+14=−7−b
6b+14=−7+−b
6b+14=−b−7
Step 2: Add b to both sides.
6b+14+b=−b−7+b
7b+14=−7
Step 3: Subtract 14 from both sides.
7b+14−14=−7−14
7b=−21
Step 4: Divide both sides by 7.
[tex]\frac{7b}{7} = \frac{-21}{7}[/tex]
b= -3
Answer:
b=−3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6b+14=−7−b
6b+14=−7+−b
6b+14=−b−7
Step 2: Add b to both sides.
6b+14+b=−b−7+b
7b+14=−7
Step 3: Subtract 14 from both sides.
7b+14−14=−7−14
7b=−21
Step 4: Divide both sides by 7.

Sue and Gwen each have large collections of CDs. Sue has twice as many CDs as Gwen. Together the girls have 96 CDs. Which equation could be used to find the number of CDs, x, that Gwen has?
Answer:
3x=96
Step-by-step explanation:
From the information given, you can write the following:
a+x=96 (1)
a=2x (2)
where a is the number of CDs that Sue has and x is the number of CDs that Gwen has.
You can replace 2 in 1 and you would have the following:
2x+x=96
3x=96
From this, you can isolate x to find its value:
x=96/3
x=32
According to this, the equation that could be used to find the number of CDs, x, that Gwen has is: 3x=96.

A rectangle that is 2 inches by 3 inches has been scaled by a factor of 7.
1. What are the side lengths of the scaled copy?
2. Suppose you want to scale the copy back to its original size. What scale factor should
you use?
Answer:
[tex]New\ Lengths = (14,21)[/tex]
[tex]New\ Scale\ Factor = \frac{1}{7}[/tex]
Step-by-step explanation:
Given
Rectangle:
Length = 2 in
Width = 3 in
Scale Factor = 7
Solving (a):
The side lengths of the new scale is calculated as follows;
New Lengths = Old Lengths * Scale Factor
[tex]New\ Lengths = (2,3) * 7[/tex]
[tex]New\ Lengths = (2 * 7,3* 7)[/tex]
[tex]New\ Lengths = (14,21)[/tex]
Solving (b): To go back to the original length
Given that the initial scale factor is 7;
The new scale factor is the reciprocal of the old factor;
Hence;
[tex]New\ Scale\ Factor = \frac{1}{7}[/tex]

7|12x+3|- 1=62 hhih
Answer:
a. x = ½, and x = -1
Step-by-step explanation:
Given the equation, 7|12x + 3| - 1 = 62, solve as follows:
Add 1 to each side of the equation
7|12x + 3| = 62 + 1
7|12x + 3| = 63
Remove the absolute value to create ± on the right side of the equation
7(12x + 3) = ±63
Solve the positive portion of the solution
7(12x + 3) = 63
84x + 21 = 63
Subtract 21 from both sides
84x = 63 - 21
84x = 42
Divide both sides by 84
x = 42/84
x = ½
Solve the negative portion of the solution
7(12x + 3) = -63
84x + 21 = -63
Subtract 21 from each side of the equation
84x = -63 - 21
84x = -84
Divide both sides by 84
x = -84/84
x = -1
The answer is: x = ½, and x = -1
