The answer is distributive.
7 is distributed to 3 + 4
Answer to the first question: 24
Answer to the second question: 2 coupons each
The given line
4x + y = 5
The slope of the given line is -4
Find the slope of perpendicular line
m₁ × m₂ = -1
-4 × m₂ = -1
m₂ = -1/-4
m₂ = 1/4
Find the equation of perpendicular line
y - y₁ = m(x - x₁)
y - 9 = 1/4(x - 8)
y - 9 = (1/4) x - 2
y = (1/4)x - 2 + 9
y = (1/4)x + 7
Answer:
27 attendees
Step-by-step explanation:
First, we can find the cost per attendee.
78÷26
3
So $3 per attendee.
Then divide 81 by 3 to find the number of possible attendees.
81÷3=27
I hope this helps!
Yes it is.
For every value of 'x' you can name, the value of 'y' is 5 .
If you mark several of those points on a graph, you see that
they form a straight line, which is horizontal and crosses the
y-axis at the point where 'y' is 5.
If the equation were not a linear one, its graph wouldn't be a straight line.
