Answer:
f(x)=1/3x+2
g(x)=1/3x+5
Step-by-step explanation:
for f(x)
So f(x) = 1/3x + 2
b is where the line hit y-axis
for g(x):
So g(x) = 1/3x+5
Let the number of weeks to have same amount = x Then:-
1200 + 40x = 700 + 50x
1200 - 700 = 50x - 40x
10x = 500
x = 50
answer is 50 weeks
Answer:
y = x - 5
Step-by-step explanation:
Equation of any two parallel lines differ only by a constant.
Therefore, the equation of the line parallel to would be ax + by + c₂ = 0.
The equation of the line parallel to should be equal to
x - y + c = 0.
Since, a point intersecting the line is given this means that the line passes through this point. This can be used to determine the value of c.
⇒ 3 -(-2) + c = -5 + c = 0
⇒ c = - 5.
Substituting we get: x - y - 5 = 0
⇒ y = x - 5 is the required equation of the line.
Answer:
924
Step-by-step explanation:
The number of students this year will be increased by 9%, so that means you'll have to multiply by 1.09 (109%). This means you take 847 * 1.09 = 923.23 students, which you then round up (because you cannot have a decimal of a student) to 924.
Answer:
12
Step-by-step explanation:
