The graph displays y = -2x + 1
So, f(-1) would be:
f(-1) = -2(-1) + 1
= 2 + 1
f(-1) = 3
Answer: B: It gets flatter
Step-by-step Explanation:
Slope is basically a ratio of the change in the x-value over the change in the y-value over a certain interval. It also shows how steep the line is. The higher (or further away from 0) the slope, the “steeper” the line is. If the slope is 0, the graph just looks like a horizontal line
1x + 4 (-×+3) = 6
1× -4× + 12 = 6
-3× = -6
× = 2
2× +2y = 6
× - y = 3
multiply second equation by 2x - 2y = 6
now add equations
4x = 12 so x = 3. substitute 3 - y = 3 so y is 0. check in first equation 2×3 + 2×0 = 6. 6+0= 6
Answer:
3/8 or 0.375 meters
Step-by-step explanation:
3.25-2.875=0.375
3 1/4 -2 7/8 = 3/8
thus the birch tree is longer than the spure tree by 3/8 meters
Answer:
4.5 miles
Step-by-step explanation:
you do 40/3 and get .75, then do .75 times 60 and you get 4.5 miles. her mile a minute ratio is 13 mins and about 23 seconds
