$1.21 is the original price per pound...i too am having trouble with figuring out how to setup the equation!!
Answer:
part A; B and Part B; pencils
Step-by-step explanation:
you want to find out how many pens and pencils you cn buy with that 90$ so you want to do
.75y+.15x=90
pens=50
pencils=50
but you want to add .75+.15 which = .90
then you divide 90/.90
and that equals 100
then split it up and each gets 50
Answer:
To draw this graph, we start from the left in quadrant 3 drawing the curve to -4 on the x-axis to touch it but not cross. We continue back down and curve back around to cross the x-axis at -1. We continue up past -1 and curve back down to 5 on the x-axis. We touch here without crossing and draw the rest of our function heading back up. It should form a sideways s shape.
Step-by-step explanation:
A polynomials is an equation with many terms whose leading term is the highest exponent known as degree. The degree or exponent tells how many roots exist. These roots are the x-intercepts.
This polynomial has roots -4, -1, and 5. This means the graph must touch or cross through the x-axis at these x-values. What determines if it crosses the x-axis or the simple touch it and bounce back? The even or odd multiplicity - how many times the root occurs.
In this polynomial:
Root -4 has even multiplicity of 4 so it only touches and does not cross through.
Root -1 has odd multiplicity of 3 so crosses through.
Root 5 has even multiplicity of 6 so it only touches and does not cross through.
Lastly, what determines the facing of the graph (up or down) is the leading coefficient. If positive, the graph ends point up. If negative, the graph ends point down. All even degree graphs will have this shape.

Essentially, you can always tell a thing's position by 3 coordinates. We also say that our world is three-dimentional: it has three dimensions -that's why three coordinates are needed.
If something is on a flat surface, you know its one coordinate (all points on the same surface have the same coordinate) so you only need two more (you can call them vertical and horizontal)
Answer:
172.7sqft (square feet)
Step-by-step explanation:
SA = 2(pi)(r)(h) + 2(pi)r^2
plug in the radius, height, and find SA, then multiply by 10 fenceposts.
SA= 2(3.14)(.5)(6)
Solve
SA=14.39166
Multiply by 12
Answer is 172.7sqft
Hope this helps!
