Answer: the equation is y = - 3x + 14
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
c represents the y intercept
m represents the slope of the straight line.
The slope of the given line is - 3 and it contains the point (4, 2)
To determine the y intercept, we would substitute m = - 3, x = 4 and
y = 2 into y = mx + c. It becomes
2 = - 3 × 4 + c
2 = - 12 + c
c = 12 + 2
c = 14
The equation becomes
y = - 3x + 14
Answer:
5
Step-by-step explanation:
Rental = $40
Catering = $12 per person
Budget = $100
Amount left after paying for the rental
= 100 - 40
= $60
Maximum number of guests
= 60 ÷ 12
= 5
Answer:
x = 3
y = -1
Step-by-step explanation:
(x-y) + (x+y) = 4 + 2
2x = 6
x = 3
sub x=3 into x+y=2
3+y=2
y=2-3
y=-1
Check by subbing x=3 and y=-1 into x-y=4
(3)-(-1) = 3+1 = 4
Those two added together are equal to
14 and
Answer:
A
Step-by-step explanation:
I agree with Katie because number is legs is directly proportional to the number of ants.
1 ant has 6 legs.
So, 2 ants have 6 *2 = 12
3 ants have 6*3 = 18
