Answer:
Its 2 i did the sheet
Step-by-step explanation:
City A and City B had two different temperatures on a particular day. On that day, four times the temperature of City A was 8° C more than three times the temperature of City B. The temperature of City A minus twice the temperature of City B was −3° C. The following system of equations models this scenario:
4x = 8 + 3y
x − 2y = −3
What was the temperature of City A and City B on that day?
City A was 5° C, and City B was 4° C.
City A was 3° C, and City B was −1° C.
City A was 8° C, and City B was −3° C.
City A was 5° C, and City B was −5° C.
Answer:
City A was 5 and city B was 4
Step-by-step explanation:
Use substitution. Move 2y over so you have x=-3+2y
Plug that into 4x=8+3y
4(-3+2y)=8+3y
-12+8y=8+3y
subtract 3y from both sides
add 12 to both sides
5y=20
20 divided by 5
y=4
then youd plug it into the other equation
x-2(4)=-3
x-8=-3
x=5
therefore the answer is A

x^3+7x^2+5x^2+35x
= x^3+12x^2+35x
Answer:
x³ + 12x² + 35x
Step-by-step explanation:
"What is (x² + 5x) multiplied by (x + 7)?
First, we can convert this into an algebraic expression!
This can be written as:
(x² + 5x)(x + 7)
We can use the FOIL Method for multiplying binomials.
FOIL: First, Outer, Inner, Last
"A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial. Then Outer means multiply the outermost terms in the product. Inner means multiply the innermost terms in the product, Last means multiply the terms which occur last in each binomial."
FOIL: First: x² × x
x² × x = x³
FOIL: Outer: x² × 7
x² × 7 = 7x²
FOIL: Inner: 5x × x
5x × x = 5x²
FOIL: Last: 5x × 7
5x × 7 = 35x
Add Everything Together!
x³ + 7x² + 5x² + 35x
Simplify:
x³ + 12x² + 35x

Answer:
area = 120√2 ft² or 169.71 ft²
Step-by-step explanation:
x² = 9² - 3² = 81 - 9 = 72
x = √72 = √(36 x 2) = 6√2 ft or 8.49 ft
area = 1/2(5 + 8)(6√2) = 120√2 ft² or 169.71 ft²
Solve the inequality.
2x + 7 ≥ -13
A. x ≥ -6
B. x ≤ -10
C. x ≤ -6
D. x ≥ -10
Answer:
D.
Step-by-step explanation:
First, move the 7 to the other side and then solve for x. You get 2x is greater than or equal to -20, or x is greater than or equal to -10.
Hopefully this helps- let me know if you have any questions!

Step-by-step explanation:
solve for x: 3 x - s = r
Answer:
Brainliest please
Step-by-step explanation:
Simplifying
3x + -1s = r
Reorder the terms:
-1s + 3x = r
Solving
-1s + 3x = r
Solving for variable 's'.
Move all terms containing s to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-1s + 3x + -3x = r + -3x
Combine like terms: 3x + -3x = 0
-1s + 0 = r + -3x
-1s = r + -3x
Divide each side by '-1'.
s = -1r + 3x
Simplifying
s = -1r + 3x
