Answer:
-8c -12 =0
-8c = 12
c = - 12/8 = -3/2
Solve by elimination.
2x + 8y = 60
5x + 4y = –10
Answer:
2x + 8y = 60= 30
5x + 4y = –10= -2
Step-by-step explanation:
Simplifying
2x + -8y = 60
Solving
2x + -8y = 60
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '8y' to each side of the equation.
2x + -8y + 8y = 60 + 8y
Combine like terms: -8y + 8y = 0
2x + 0 = 60 + 8y
2x = 60 + 8y
Divide each side by '2'.
x = 30 + 4y
Simplifying
x = 30 + 4y
A small software development company invests $16,000 to produce a software package that will sell for $50.65. Each unit costs $8.20 to produce. How many units must the company sell to break even? How many units must the company sell to make a profit of $95,000?
Answer:
376 units and 1,857 units
Step-by-step explanation:
The computation is shown below:
The number of units that company sells to break even is
Let us assume the number of units be x
$16,000 + $8.20x = $50.75x
$16,000 = $50.75x - $8.20x
$16,000 = $42.55
x = $16,000 ÷ $42.55
= 376 units
Now in order to make the profit the number of units sold is
$50.65x - ($16,000 + $8.20x) = $95,000
$50.65x - $16,000 - $8.20x = $95,000
$42.55x = $95,000 - $16,000
$42.55x = $79,000
x = $79,000 ÷ $42.55
= 1,857 units

If the point (3,-4) is dilated by a scale factor of 74 , what are the new coordinates?
Now take the new points and rotated them 180°. What are the new coordinates?
Answer:
(-222, 296)Step-by-step explanation:
Given point
(3, -4)Dilation by a scale factor of 74:
(x, y) → (74x, 74y)(3, -4) → (74*3, 74(-4)) = (222, -296)Rotation by 180°:
(x, y) → (-x, -y)(222, -296) → (-222, 296)Answer the question below please.

Domain and Range for the function f(x)=5IXI is
Answer:
The domain of the function f(x) is:
[tex]\mathrm{Domain\:of\:}\:5\left|x\right|\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]
The range of the function f(x) is:
[tex]\mathrm{Range\:of\:}5\left|x\right|:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:0\:\\ \:\mathrm{Interval\:Notation:}&\:[0,\:\infty \:)\end{bmatrix}[/tex]
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=5\left|x\right|[/tex]
Determining the domain:
We know that the domain of the function is the set of input or arguments for which the function is real and defined.
In other words,
Domain refers to all the possible sets of input values on the x-axis.It is clear that the function has undefined points nor domain constraints.
Thus, the domain of the function f(x) is:
[tex]\mathrm{Domain\:of\:}\:5\left|x\right|\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]
Determining the range:
We also know that range is the set of values of the dependent variable for which a function is defined.
In other words,
Range refers to all the possible sets of output values on the y-axis.We know that the range of an Absolute function is of the form
[tex]c|ax+b|+k\:\mathrm{is}\:\:f\left(x\right)\ge \:k[/tex]
[tex]k=0[/tex]
so
Thus, the range of the function f(x) is:
[tex]\mathrm{Range\:of\:}5\left|x\right|:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:0\:\\ \:\mathrm{Interval\:Notation:}&\:[0,\:\infty \:)\end{bmatrix}[/tex]

Can someone plz help me. There is an equation and the cost too.
Answer:
C = 40p
Cost for 15 people: 600 dollars
Step-by-step explanation:
The amusement park charges $40 per person.
That can be represented as 40 × P or 40P.
C is equal to the cost of admission for P people.
So, C = 40P
C = 40P
C = 40(15)
C = 600
The cost of admission for 15 people is 600 dollars.

Salvador sold hats during the weekend sporting event. On Saturday, Salvador sold ( * of the total number of hats. On Sunday, he sold & ( of the total number of hats. What fraction of the total number of hats was left over?
Answer:
5/28
Step-by-step explanation:
Salvador sold hats during a weekend sporting event. On Saturday, Salvador sold 4/7 of the total number of hats. On Sunday, he sold 1/4 of the total number of hats. What fraction of the total number of hats was left over
Total number of hats = x
Hats sold on Saturday = 4/7x
Hats sold on Sunday = 1/4x
Hats left over = x - (4/7x + 1/4x)
= x - ( 16x+7x/28)
= x - 23/28x
= 28x - 23x/28
= 5/28x

Maria can paint an area of 100 square feet in one-third of an hour. At this rate, how
many square feet can she paint in one minute?
Answer:
A. 5 square feet per minute
Step-by-step explanation:
Answer:
The answer is 5 square feet per minute.
Step-by-step explanation:
Since 1/3 of an hour is 20 minutes, it will look like 100 square feet/20 min.
To make 20 minutes into one minute, we have to divide it by 20.
Because we did it to the denominator, we also have to do the same thing to the numerator.
Divided 100 by 20, which gives you 5.
