y = 2x - 8 3x - 2y = 13
Answers
Answer:
{x,y} = {3,-2}
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = 2x - 8
// Plug this in for variable y in equation [2]
[2] 3x - 2•(2x-8) = 13
[2] -x = -3
// Solve equation [2] for the variable x
[2] x = 3
// By now we know this much :
x = 3
y = 2x-8
// Use the x value to solve for y
y = 2(3)-8 = -2
Solution :
{x,y} = {3,-2}

Step-by-step explanation:
Interior angles of a triangle sum up to 180
180 - 90 = 90
90 / 2 = 45
Answer:
X = 45
Step-by-step explanation:
Since all interior angles of a triangle add up to 180 and both of the missing angles are the same value, X would equal 45,
90+45+45=180

Area of smaller parallelogram = 15 ft?
Answers
Answer:
135ft^2
Step-by-step explanation:
Area of the smaller parallelogram = Base * Height
15 = 3 * height
Height = 15/3
Height = 5ft
Since they are both similar
Height of the big parallelogram = 3(5) = 15ft
Area of the other parallelogram = 9 * 15
Area of the other parallelogram = 135ft^2
how do u solve problems like this ?
Answers
The first and second polygons are exactly the same, the only difference is that the second is bigger! If we look right the first polygon is 4 cm and the second is triple which means that we will have to triple the area of the First polygon to discover the area of the second polygon!
Resposta:if the first polygon is 4 cm long and the second 12 cm means that the second polygon has three times the area of the first polygon!
[tex](4 cm.3=12 cm)\\A-10 cm^{2}.3=30 cm^{2}[/tex]
the second polygon has [tex]30 cm^{2}[/tex] of area
[tex]A=30 cm^{2}[/tex]

a. P 82.50
b. P 8.50
c. P 825
d. P 85
Answers
Answer:
the answer for the discount is A. P 82.50
Step-by-step explanation:
Finding the Discount
The discount refers to the amount being deducted from the original price. It is determined by the rate. To find the discount, multiply the rate by the original price.
Given:
original price - P 550.00
rate - 15%
Equation:
Remember to convert the rate to decimal by dividing it by 100.
P 550.00 × 0.15 = N
Solution:
P 550.00 × 0.15 = P 82.50
Final Answer:
P 82.50

the sum of the square of two consecutive positive integers is 85. Write a quadratic equation
Answers
Answer:
2x^2 + 2x - 83 = 0
Step-by-step explanation:
Consecutive integers differ by 1
Let the first number be x
The next will be (x+1)
The sum of the squares of these two numbers is 85
so we have;
x^2 + (x + 1)^2 =85
= x^2 + x^2 + 2x + 2 = 85
2x^2 + 2x + 2-85 = 0
2x^2 + 2x - 83 = 0

In a college philosophy class during the fall semester, there were 323 students,42% of whom were male and the rest of whom were female. In the springsemester, the same number of females was in the class as in the fall, but there were only 298 total students in the class. In the spring, what percent of students were female?
A. 46%B. 58%C. 63%D. 92%
Answers
Using the percentage concept, it is found that the percentage of female students in the spring was of:
C. 63%
What is a percentage?The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
[tex]P = \frac{a}{b} \times 100\%[/tex]
During the fall semester, 58% of 323 students were female, hence:
0.58 x 323 = 187.
Then, during the spring semester, the same amount out of 298, hence:
[tex]P = \frac{187}{298} \times 100\% = 63\%[/tex]

4) solve for n, show all work
—6 ( — 2 n + 4 ) = 24
Answers
Answer: n = 4
Step-by-step explanation:
-6(-2n + 4) = 24 (divide both sides by -6)
-2n + 4 = -4 (subtract 4 from both sides)
-2n = -8 (divide by -2 on both sides)
n = 4
Answer:
12n - 24 = 24
add 24 to both sides
12n = 48
divide 12 from both sides
n = 4

Liu is making a rabbit pen. The graph shows where he plans to place it in his backyard. Each unit on the graph represents 1 foot.
1. What is the distance between points R and U? Explain how you found this distance.
2. Find the other three side lengths.
The length of the side between U and T is _______ feet.
The length of the side between T and S is _______ feet.
The length of the side between S and R is _______ feet.
3. The perimeter is the sum of the side lengths. What is the perimeter of the pen?
4. Does Liu have enough fence to make the pen? Why or why not?
Answers
Answer:
1. The distance between the points R and U is 4 feet
2. The length of the side between U and T is 3 feet
The length of the side between T and S is 4 feet
The length of the side between S and R is 3 feet
3.The perimeter of the pen is 14 feet
4. Yes
Liu has enough fence to make the Pen because he has more fence than the perimeter of the pen
Step-by-step explanation:
The 'x', and 'y' (x, y) coordinates of the points are;
R(5, 7), U(5, 3), S(8, 7), T(8, 3)
1. From the graph, the distance between the points R and U is given by the change in the values of the y-coordinate, given in feet, since the x-coordinate values are the same
Therefore, the distance between the points R and U = 7 ft. - 3 ft. = 4 ft.
2. Similarly, the length of the side between U and T is given by the change in the values of the x-coordinate, given in feet, since the y-coordinate values of U ant T are the same, as follows;
The length of the side between U and T = 8 ft. - 5 ft. = 3 ft.
Similarly the length of the side between T and S which have the same x-coordinate values is given as follows
The length of the side between T and S = 7 ft. - 3 ft. = 4 ft.
The length of the side between S and R which have the same y-coordinate values is given as follows;
The length of the side between S and R = 8ft. - 5ft. = 3ft.
3. The perimeter of the pen = Length R and U + Length U and T + Length T and S + Length S and R
∴ The perimeter of the pen = 4 ft. + 3 ft. + 4 ft. + 3 ft. = 14 ft.
4. The length of fencing Liu has = 16 feet (from internet source)
Therefore, the length of fence Liu has, 16 ft.is more than the length that make up the perimeter of the pen, 14 ft.
Therefore Liu has enough fence to make the Pen because the length of fence he has is more than the perimeter of the pen.
