Solve the system of linear equations by substitution.
y = 2x + 8
y = -2x
Answers
Answer:
(- 2, 4 )
Step-by-step explanation:
y = 2x + 8 → (1)
y = - 2x → (2)
substitute y = 2x + 8 into (2)
2x + 8 = - 2x ( add 2x to both sides )
4x + 8 = 0 ( subtract 8 from both sides )
4x = - 8 ( divide both sides by 4 )
x = - 2
substitute x = - 2 into (2)
y = - 2(- 2) = 4
solution is (- 2, 4 )

Carlos uses a food delivery service to order lunch. He paid $13.75 for lunch, which included the cost of the food and a delivery fee, which is 10% of cost of the food. What was the cost of Carlos' lunch before the delivery fee? Enter your answer in the box.
Answers
Answer:
$12.50
Step-by-step explanation:
Let x = the cost of the food without the delivery fee.
The delivery fee can be represented as 0.10x.
Keep in mind that the cost of the food plus the delivery fee equals $13.75.
Therefore, your equation will look like: 13.75 = x + 0.10x
x + 0.1x = 1.10x
So, 13.75 = 1.10x
This means that x = 13.75/1.10
x = 12.5 = $12.50
Answer: Let's represent the cost of the food as "x".
We know that the delivery fee is 10% of the cost of the food, so it can be written as 0.1x.
The total cost that Carlos paid for lunch is the sum of the cost of the food and the delivery fee, which is:
Total cost = Cost of food + Delivery fee
$13.75 = x + 0.1x
Simplifying the equation, we get:
$13.75 = 1.1x
Dividing both sides by 1.1, we get:
x = $12.50
Therefore, the cost of Carlos' lunch before the delivery fee was $12.50.

PLEASE HELP ME IF YOU CAN AS SOON AS POSSIBLE. THANK YOU
Answers
(220,10)
Step-by-step explanation:
This reminds me of when I was in middle school
Answer:
(110, 135)
Step-by-step explanation:
From the coordinates given, the shape of the ceiling is a rectangle.
Width = difference in x-coordinates = 220 - 0 = 220
Length = difference in y-coordinates = 260 - 10 = 250
To find the center of the ceiling, we need to find the centroid (center-point) of the rectangle.
x-coordinate = Half of the width + smallest x-coordinate= (220 ÷ 2) + 0 = 110
y-coordinate = Half of the length + smallest y-coordinate = (250 ÷ 2) + 10 = 135
Therefore, the center of the ceiling is at (110, 135)

Cory writes the polynomial x7 3x5 3x 1. Melissa writes the polynomial x7 5x 10. Is there a difference between the degree of the sum and the degree of the difference of the polynomials?.
Answers
Degree of a polynomial gives the highest power of its terms. Yes there is a difference between the degrees of sum and difference of the polynomials.
What is degree of a polynomial?Degree of a polynomial is the highest power that its terms pertain(for multi-variables, the power of term is addition of power of variables in that term).
Thus, in [tex]x^3 + 3x^2 + 5[/tex], the degree of the polynomial is 3 as the highest power in its terms is 3.
(power and exponent are same thing)
What are like terms?Those terms which have same variables raised with same powers.
For example, [tex]x^3[/tex] and [tex]3x^3[/tex] are like terms since variable is same, and it is raised to same power 3.
For example [tex]4x^2[/tex] and [tex]x^3[/tex] are not like terms as the variables are same but powers aren't same.
The given polynomials are:
[tex]c(x) = x^7 + 3x^5 + 3x + 1\\\\p(x) = x^7 + 5x + 10[/tex]
Their sum is
[tex]c(x) + p(x) = x^7 + 3x^5 + 3x + 1 + x^7 + 5x + 10 = (1+1)x^7 + 3x^5 + (3+5)x + 11\\\\c(x) + p(x) = 2x^7 + 3x^5 + 8x + 11[/tex]
(only like terms' coefficients can be added (or subtracted) for addition or subtraction of them )
The sum's degree is 7
Their difference is:
[tex]c(x) - p(x) = x^7 + 3x^5 + 3x + 1 - x^7 -5x - 10 = (1-1)x^7 + 3x^5 +(3-5)x -9\\\\c(x) - p(x) = 3x^5 - 2x - 9[/tex]
Difference's degree is 5
Thus, both's degrees are not same.
Thus, Yes there is a difference between the degrees of sum and difference of the polynomials.
