This is my work. Also 2/3 is a repeating decimal so it’s actually 0.6...
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
When you want to find out what the slope is, you have to remember what the formula is first....

so in this case -3 would be the
because it's the y in the ordered pair and it's the second one. Then one of the 5's would be
and 9 would be
and then the other 5 would be
.
now if we plug it in

now we can tell that we can't divide by zero so the slope would be unidentified and that's it.
$ 3.50 per lb * 1 1/2 lbs
3.50 per lb * 1.5 lbs = 5.25
It will cost $5.25
Answer:
y = 0.87x + 0.02
Step-by-step explanation:
Euros as a function of dollars means that euros is y and dollars are x.
We are given 2 points: (4, 3.5) and (10, 8.72)
slope = (8.72 - 3.5)/(10 - 4)
slope = 5.22/6 = 0.87
y = 0.87x + b
3.5 = 0.87(4) + b
b = 0.02
y = 0.87x + 0.02
-17/2
Step-by-step explanation:
30-8(8)+4y
30=64+4y
30-64=4y
-34=4y
y= -34/4
y= -17/2
hope it helps!
