Write an equation of a line with the given slope and y-intercept. m = 4/5 , b = 2 y = 2x + y = x – 2 y = x + 2 y = x + 2
1 answer:
Answer:
Step-by-step explanation:
Put the slope value given as the coefficient of x.
It is the "m" in the formula y = mx + b
I'm not sure what the other equations in the question are there for. Maybe to change from slope-intercept form to standard form?
y = 2x +
y = x – 2 becomes y -x = -2 or x - y = 2
y = x + 2 becomes y -x = 2 or x - y = -2

Answer:
Total number of people in the stadium = 520
Step-by-step explanation:
Let the total number of people in the stadium = x
Since, 25% of the fans are teenagers, number of teenagers in the stadium
= 25% of x
=
= 0,25x
If the number of teenagers in the stadium = 130
0.25x = 130
x =
x = 520
Therefore, total number of fans in the stadium = 520.
