The temperature in Minsk was recorded over a period of four hours. The equation y = -5x + 54
describes the temperature over this time, where y is the temperature in degrees Fahrenheit (°F) and c is the number of hours since measurements started. Which of the following statements correctly describes the temperature?
A: It was 54°F after four hours, and it is dropping by 5 degrees per hour.
B: It was -5°F when the temperature was first measured, and it is rising by 54 degrees per hour.
C: It was -5°F after four hours, and it is rising by 54 degrees per hour.

25. 3r^2
Step-by-step explanation:
I don't know if I did it correctly but based on what I understand I think this is how you do this exercise.
Example: 5x^2 - 2x + 1 < This is a Trinomial because it has three terms, but there is more to it.
In 5x^2 - 2x + 1, the highest exponent is 2 (^2 from 5x^2) < therefore this is a 2nd-degree Trinomial.
Another example: 3x^4 + 4x^2 < This is a Binomial (two terms) but there's more to it.
In 3x^4 + 4x^2, there are two different exponents 4 and 2, but we are focusing on the highest exponents which is 4 (^4 from 3x^4) < therefore this a 4th-degree Binomial.
Hope this can help you in the future!

Answer:
a 25 square units
Step-by-step explanation:
first find the length of the two sides of the triangle (sides of square 1 and 2)
the perimeter of a square is the length of the side × 4
so to find the length of the side, divide the perimeter by 4
perimeter of square 1: 12 units
divide it by 4: 3 units, so that's the length of side 1
perimeter of square 2: 16 units
divide it by 4: 4 units, so that's the length of side 2
now use a2 + b2 = c2
3 squared + 4 squared = c2
and solve
9 + 16 = c2
25 = c2
square root of 25 = square root of c2
5 = c
So now multiply 5 × 5 to find the area of the square

d.-23=4a-15
e.-90=-9-9a
Answers
Answer:
a. 1
b. -5
c. -9
d. -2
e. 11
Step-by-step explanation:
a. -7 = 3a-10
-7+10 = 3a
3 = 3a
a = 1
b. 2a+13 = 3
2a = 3-13
2a = -10
a = -10/2
a = -5
c. -5a+14 = 59
-5a = 59-14
-5a = 45
-a = 9
a = -9
d. -23 = 4a-15
-23+15 = 4a
-8 = 4a
-2 = a
a = -2
e. -90 = 9-9a
-90-9 = -9a
-99 = -9a
-99/-9 = a
11 = a
a = 11

Answers
Answer:
18.72
Step-by-step explanation:

cost of one carton = $ 5.76/4
cost of 13 cartons= $ 5.76/4× 13
=$ 18.72
Step-by-step explanation:
Cost of four cartons: 5.76
Cost of one carton: 5.76/4 times 13.
Cost of 13 cartons: 5.76/4 times 13 = 18.72

Question 1- Y= -6x - 4
Question 2- -6
Step-by-step explanation:
If this is the original question, 12x + 2y = -8, you first need to move x to the right like so ----- 12x + 2y = -8
-12x - 12x
Leaving you with 2y = -12x -8. Then dived both sides by the Y coefficient ---------- 2y = -12x -8
/ 2 /2 /2
For the final answer---- Y = -6x -4
For question 2- Just take M from the top and put it in there ------- -6
Hope this helps. Comment below if you have any other questions. I'd be happy to explain!
12x+2y=-8
-12x on both sides
2y = -12x -8
/2 on both sides
y = -6x -4
