Answer:
starts wuth 46, and sells half, so she has 23. then when she buys 17 more she then has 40.
if you are asked to show work its 46/2=23, then 23+17=40!
Yes it a mathematical sentence because it has the verb "is equal" in the sencence.
x = 1 translates to:
x is equal to 1 - notice the "is equal"
x + 1 is not a sentence because there is no "is equal" in the word form
x plus 1 (this needs more to it to understand)
Answer:
100 minutes
Step-by-step explanation:
Let
x ----> the number of minutes
y ----> the total cost of the plan
we know that
<em>Cingular Plan</em>
-----> equation A
<em>Verizon Plan</em>
-----> equation B
To find out how many additional minutes will it take for the two plans to cost the same
Solve the system of equations A and B
Solve by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (100,84.99)
see the attached figure
therefore
For x=100 minutes
The cost for both plans is $84.99
I don't exactly want to give away the answers, but I can give away a key that helps you in getting the answers. Every line is 180 degrees. So if you add up all the angles on that line, let's take number one as an example, you will get 140 degrees. Now, to find the last angle, you subtract 180 with whatever you have. As a simplified version, here are some steps:
1. Add all the angles
2. Subtract 180 with your result
3. enjoy the satisfaction of finishing math work
Answer:
1
Step-by-step explanation:
f(0) is another way of saying 'what is Y when X is 0'. If you look at the graph, when X is 0, Y is 1.
