i think there is a trick so the 3 nbs are 9+11+13=33
How's that we need 30
if we flip 9 we get 6
so the answer would be 6+11+13=30
Since the lines are parallel, you know that they have the same slope, which is 2. If you look at the coordinate grid you can see that line y_{2} crosses the y-axis at (0, 1), making the y-intercept 1. Now that you know the slope is 2 and the y-intercept is 1, you can piece those into a slope-intercept equation.
y = mx + b where m is the slope and b is the y-intercept
y_{2} = 2x + 1
Answer:
B
Step-by-step explanation:
Step-by-step explanation:
-inf<= x <= inf
-inf<= y <= 4
It is a function
Let b>a,
a+b=40 so we can say a=40-b
We are told that b-a=6.5, using a found above in the equation gives us:
b-(40-b)=6.5
b-40+b=6.5
2b-40=6.5
2b=46.5
b=23.25, and since a=40-b
a=40-23.25
a=16.75
So a=16.75 and b=23.25
check...
16.75+23.25=40, 40=40
23.25-16.75=6.5, 6.5=6.5
