Answer:
C, D, and E
Step-by-step explanation:
When trying to solve for the cost of each item you will find a rainbow fish is $8.50 and a tetra is $2.50. If you use that information to solve the other answer choices C, D, and E would be correct
Answer:
Two equal sides = 14.4 inches each
Shortest side = 7.2 inches
Step-by-step explanation:
a + b + c = 36
a = b
a = 2c
then:
c = a/2
a + a + a/2 = 36
2a + a/2 = 36
4a/2 + a/2 = 36
5a/2 = 36
a = 2*36/5
a = 72/5
a = 14.4
a = 2c
14.4 = 2*c
c = 14.4/2
c = 7.2
a = b
b = 14.4
Check:
14.4 + 14.4 + 7.2 = 36
18=3+36x-50x-55
18=3-14x-55
18=-14x-52
70=-14x
x=-5
Answer:
-6 is less than -5
Step-by-step explanation:
any negative number is always lower than a positive number
Answer: Choice H
y = -2x+3
=========================================================
Explanation:
Start at any point you want on the diagonal line. Notice how we move down 2, right 1 to get to a neighboring point. This "down 2, right 1" motion determines the slope
- rise = go down 2 units
- run = go right 1 unit
slope = rise/run = -2/1 = -2
So m = -2 is the slope
Another way to find the slope is to use the slope formula for any two points on that diagonal line.
The y intercept is 3 because this is where the diagonal line crosses the y axis. This means b = 3.
---------------------
To summarize, we found that m = -2 is the slope and b = 3 is the y intercept.
We go from y = mx+b to y = -2x+3
