Answer:
2x-y-1=0
Step-by-step explanation:
A(4,7)
B(2,3)
(y-ya)/(yb-ya)=(x-xa)/(xb-xa)
(y-7)/(3-7)=(x-4)/(2-4)
(y-7)/-4=(x-4)/-2
(7-y)/4=(4-x)/2=2(4-x)/4
so 7-y=2*4-2x
y=-8+2x+7
2x-y-1=0
Answer:
Josh was driving faster

Answer:
Lowest: 78
Highest: 99
Step-by-step explanation:
Quiz 1 =A
Quiz 2 = B
B = 21 + A
2A = 57 + B
2A = 57 + (21 + A)
2A = 78 + A
A = 78
B = 21 + A
B = 21 + 78
B = 99
The range is {-4. -2, 0, 2, 4}
The range of any relation is simply the possible y values. In this relation, there are only 5 possible values, so we list them as seen above.
Answer:
Step-by-step explanation:
If we consider x as days and y as gumballs we can write this equation
y = -2x + 20
we can now fit the table
x = 0 ; y = 20
x = 1 ; y = 18
x = 2 ; y = 16
x = 3 ; y = 14
x = 4 ; y = 12
x = 5 ; y = 10
x = 6 ; y = 8
x = 7 ; y = 6
x = 8 ; y = 4
x = 9 ; y = 2
x = 10 ; y = 0
the x intercepts indicate that when 10 days will pass, the gumballs will finish
the y intercepts indicate the initial amount of gumball before Mrs Labella will start to eat them
