Answer:
x = -5 and y = 1
Step-by-step explanation:
a) 2x + 5y +5 = 0
a) 2x + 5y = -5
b) 2y = 3x + 17
b) y = 3/2x + 17/2
a) 2x + 5(3/2x + 17/2) = -5
a) 2x + 15/2x + 85/2) = -5
a) 19/2x = -5 - 85/2
a) 19/2x = -95/2
a) x = (-95/2) / (19/2)
x = -5
b) 2y = 3(-5) + 17
b) y = 2/2
y = 1
The situation that represents the expression 2 - 5 is (a) the temperature was 2°C and has decreased by 5°C
<h3>How to determine the situation?</h3>
The expression is given as:
2 - 5
When the expression illustrates change in temperature, the interpretation can be:
An initial temperature of 2°C decreases by 5°C
Hence, the situation that represents the expression 2 - 5 is (a) the temperature was 2°C and has decreased by 5°C

Answer:
24
Step-by-step explanation:
If this is an answer 24 because when there were 50 tickets sold there were 12 so when there is 100 tickets sold you double 12 to get 24
Hope this makes since and please do not come after me if this is wrong.
Answer:
y=14x+56
Step-by-step explanation:
Question says to find the equation in slope intercept form that means we have to use y=mx+b form.
Where b is the initial value or you can say y-value when x=0
Given that at shift x=0, number of people y=56
so that means b=56
now find the difference between consecuitve value of y
70-56=14
84-70=14
98-84=14
We are getting constant difference of 14 so that mean slope m=14
now plug values of m and b into y=mx+b
Then final answer will be y=14x+56
