Answer:
The third option (the one that looks like a V but isn't sideways.
To find a function use the vertical line test. To do that you see if a vertical line passes through one or multiple points. If it passes through more than one point anywhere then it isn't a function.
78 + 96 + 40 + 104 + 77
174 + 40 + 104 + 77
214 + 104 + 77
318 + 77
395
395/5 = 79
answer:
-1
work:
y = mx+ b
so we can tell that the Y intercept is 1, so we can plug that in. ( + b is the y-intercept)
y = mx + 1
plug in some values to find the slope.
(-1, 2)
2 = -m + 1
- 1 - 1
1 = -1m
/-1 /-1
-1 = m
the slope is -1.
i hope this helps! :D
Answer:
28 shirts
Step-by-step explanation:
Let's see what we are given.
there are x amount of shirts ($616 total)
there are 12 in a dozen
the regular shirts are $16
the last 12 shirts are $14
Lets make an equation.
616= 14(12) + 16x
616=168+16x
448=16x
x=28
(Sorry if this explanation is bad)
