Answer: (0,1)
Step-by-step explanation:
x-5y=-1
+5y
x= -1+5y
+1
x+1= 5y
Y intercept would be 1

Answer: g(x) = 5x+9, second choice</h3>
Explanation:
When we reflect over the vertical y axis, every negative x value becomes positive and vice versa. So we effectively replace x with -x like so
f(x) = -5x+9
f(-x) = -5(-x)+9 ... replace every x with -x
f(-x) = 5x+9
g(x) = 5x+9
A point like (1,4) on f(x) will reflect over to (-1,4) on g(x). If we apply this to every point on f(x), then all of f(x) will reflect to g(x).
Answer:
y=11.142857
Step-by-step explanation:
Simplify 5.2/3.5 to 1.485714
1.485714=y/7.5
Multiply both sides by 7.5
1.485714× 7.5=y
Simplify 1.485714×7.5 to 11.142857
11.142857=y
Switch sides
y=11.142857
Answer:
Well 40% of 120 is 48 so 48 students
Step-by-step explanation:
There has been 28 years since 1985 to 2013, this becomes your x value. Plug x into the equation:
f(x) = (.65*28)+24.75
f(x) = 18.2+24.75
f(x) = 42.95
