(a,1)(a,2)(a,3)(a,4)(b,1)(b,2)(b,3)(b,4)
Answer:
no solution
Step-by-step explanation:
Hi there!
We are given this system of equations:
y=-2x+5
y=-2x+20
and we want to find the solution (the point in which the lines intersect)
There are 3 ways to solve a system, but let's use substitution in this case
Both equations are set to y, so they should be equal to each other via a property known as transitivity (if a=b and b=c, then a=c)
-2x+5=-2x+20 (the same as y=y)
Now let's solve for x
add 2x to both sides
5=20
In this case, we got an untrue statement. If this happens, then the lines won't intersect.
If they won't intersect, there's <u>no solution </u>
Hope this helps!

Just start with 14 and go up and then start at 150 and go down by 12 until they meet
The machine make nails at a rate of 8th pounds per hour
<h3>How to determine the rate of making machine?</h3>
From the question, the given parameters are:
- Amount of pounds of nails = 4th pounds
- Number of time = half an hour
The rate in pounds per hour the machine make nails is then calculated as
Rate of making nails = Amount of pounds of nail/Number of time
Substitute the known values in the above equation
So, we have
Rate of making nails = 4th pounds/0.5 hour
Evaluate
Rate of making nails = 8th pounds per hour
Hence, the rate of making nails is 8th pounds per hour

Answer:
B
Step-by-step explanation:
V=4/3 x 3.14 x 3^3
V= 113.04
SA= 4 x 3.14 x 3^2
SA= 113.04
