Answer:
Option C 
Step-by-step explanation:
Let
x ----> the cost of the concert ticket
we know that
The total cost to be no more than $4 Above $80
so
Solve for x
The total cost to be no more than $4 below $80
so
Solve for x
therefore
The inequality that represent this problem is
<u><em>Verify</em></u>
<em>First solution (positive case</em>)
Solve for x
----> is ok
<em>Second solution (negative case)</em>
Multiply by -1 both sides
Solve for x
---> is ok
Remember that
is equivalent to
Because is a absolute value
Answer:
x = 5 only
≡ On a graph, the point touches (5, 0), making <em>x</em> equal to 0.
≡ In other words, you must replace <em>y</em> with <em>0</em> to solve for <em>x. </em>There is no <em>y</em> term in this problem, so you must determine <em>y</em> by separating the coefficients into groups and determining each part.
Answer:
Cameron need to mow 4 lawns.
Step-by-step explanation:
Cameron needs 11$ for some new toys.
But he charges 3$ to mow a lawn.
So, he needs to mow 11/3= 3.66... lawns
The number of lawns can not be decimal. So, let's round to next whole number as 4.
Answer:
Yes.
Step-by-step explanation:
Though x and y can be achieved in a system of equations. The equation
x (t)=0.0411905(t^2)+(-0.164619)t+28.0114
And
y (t)=-0.024127(t^2)+(-0.591143)t+(-87.4403)
Are not system of equations but rather two different models of equations. Nevertheless
To find t in the first equation, x(t) has to be equal to zero.
When the t is substituted in the second equation, t will completely disappear. Given the value of y(t) and vice versa.
