Here is a system of equations. y=2x-1 y=-x-4 Graph the system. Then write its solution. Note that you can also answer "No solution" or "Infinitely many" solutions.
Answer:
The solution of the given system is: (-1,-3)
Step-by-step explanation:
Given equations are:
[tex]y = 2x-1\\y = -x-4[/tex]
Solving a system using graph means plotting the lines represented by the system of equations and then finding out where the lines intersect. If the lines intersect at only one point, that point is solution of the system.
We have used the online graphing calculator "Desmos" plot the lines.
Manually, the points can be obtained by substituting values of x in both equations
In the attached picture, the red line represents the first equation and the blue line represents the second. Both lines intersect at (-1,-3)
Hence,
The solution of the given system is: (-1,-3)

Find the final sale price of a basketball that is $ 35 which is on sale for 50% and then gets an additional 10% off.
Answer:
$15.75
Step-by-step explanation:
$35 * 0.50 = 17.5
$35 - $17.50 = $17.50
$17.50 * 0.10 = $1.75
$17.50 - $1.75 =$15.75
Answer:
$15.75Step-by-step explanation:
To find the percent of a number, we need to express the percent as a decimal with the decimal point of the original percent moved two places to the left. We cannot add the two percents together. You are only paying 50% of the original price.
50% = 0.5
We will now move to decimal two places to the left.
0.005 x 35 = 17.50
Now, we find 90% (since we only care about the amount you are paying) of $17.50
0.009 x 17.50 = 15.75

Answer:
[tex][f(x)]^2-g(x) = 5x^2-13x-8[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 2x-2\\g(x) = -x^2+5x+12[/tex]
To find: [tex][f(x)]^2-g(x)[/tex]
First of all the square of first function f(x) will be found and then second function g(x) will be subtracted from the square of first function
Squaring the first function
[tex][f(x)]^2 = (2x-2)^2\\Using\ (a-b)^2 = a^2-2ab+b^2\\\[f(x)]^2 = (2x)^2-2(2x)(2)+(2)^2\\= 4x^2-8x+4[/tex]
Now subtracting g(x) from [f(x)]^2
[tex][f(x)]^2-g(x) = (4x^2-8x+4)-(-x^2+5x+12)\\\[f(x)]^2-g(x) = 4x^2-8x+4+x^2-5x-12[/tex]
Combining alike terms
[tex][f(x)]^2-g(x) = 4x^2+x^2-5x-8x+4-12\\\[f(x)]^2-g(x) = 5x^2-13x-8[/tex]
Hence,
Subtracting g(x) from the square of f(x) gives us:
[tex][f(x)]^2-g(x) = 5x^2-13x-8[/tex]
Solve for x and verify:3(x+3)-2(x-1)=5(x-5)
Answer:
x=9
Step-by-step explanation:
Distribute:
3x+9-2x+2=5x-25
Combine like terms:
x+11=5x-25
Solve:
x-x+11=5x-x-25
11=4x-25
11+25=4x-25+25
36=4x
Divide by 9:
x=9.
Hope this helps :D
Answer:
x = 9
Step-by-step explanation:
Step 1: Solve both sides by distributing the values.
3x+9-2x+2 = 5x-25
Step 2: Put the like terms together.
3x-2x-5x = -25-9-2
-4x = -36
Step 3: Divide both sides by -4 to get the value of x.
[tex]\frac{-4x}{-4}[/tex] = [tex]\frac{-36}{-4}[/tex]
x = 9
Let's verify the answer.
3x+9-2x+2 = 5x-25
3(9)+9-2(9)+2 = 5(9)-25
27+9-18+2=45-25

Determine the domain and range of the function shown in the graph.
Answer:
The domain and range of the function shown in the graph will be:
{x|x ≥ -4}; {y|y ≥ 2}
Thus, option 2 is true.
Step-by-step explanation:
We know that domain is the set of all possible values for which is the function is defined.First, let's check the domain. We see a closed circle at x = -4 and the graph is heading towards +ve infinity i.e. [-4, ∞).
A closed circle means the point is included in the domain.
Therefore, the domain is:
{x|x ≥ -4}
We know that the range is the set of values of the dependent variable for which a function is defined.Now, let's check the range. We see a closed circle at y = 2 and the y-values of the graph are heading towards +ve infinity. i.e. [2, ∞)
Therefore, the range is:
{y|y ≥ 2}
Hence, the domain and range of the function shown in the graph will be:
{x|x ≥ -4}; {y|y ≥ 2}
Thus, option 2 is true.
An investor flips a house, selling it for $88,000. If her profit was 30%, how much did she pay for the house originally? Round to two decimal places.
Answer:
She paid $67692.31 for the house originally.
Step-by-step explanation:
Let the initial cost of the house be [tex]x[/tex] dollars.
Given:
Selling price of the house (S.P) = $88000
Profit made = 30% of 'x' = [tex]0.30x[/tex]
We know that,
Profit = Selling Price - Original price
[tex]0.30x = 88000 - x[/tex]
Adding [tex]x[/tex] on both sides, we get:
[tex]0.30x+x = 88000\\\\1.3x=88000[/tex]
Dividing both sides by 1.3, we get:
[tex]x = 88000/1.3\\\\x = \$ 67692.307[/tex]
Rounding to 2 decimal places, we get:
[tex]x=\$67692.31[/tex]
Therefore, she paid $67692.31 for the house originally.
