Answer:
p = 2.7x - 20
p(90) = $223
Step-by-step explanation:
revenue → f(x) = 3x ,where x is the number of downloads.
the statement “Your profit p is $20 less than 90% of the revenue for x downloads”
<u><em>means</em></u>

<u><em>means</em></u>
<u><em></em></u>
<u><em>means</em></u>

<u><em>means</em></u>

<u><em>means</em></u>

………………………………
the profit for 90 downloads :
= p(90)
= 2.7×(90) - 20
= $223
<u>Answer:</u>
<em>Equation is 4x-6(6x-1) = -11
</em>
<u>Step-by-step explanation:</u>
<em>The set of equations given are
</em>
<em>6x-y=1
</em>
<em>4x-3y=-11
</em>
A pair of linear equations in <em>two variables x and y is given</em> in the set of equations. If there are two variables we require two equations to find the <em>value of variables</em>. Substitution is one among the methods used to solve pair of linear equations in two variables.
Here we have to <em>determine the value of y</em> from the first equation and then substitute it in the second equation.
<em>6x-y=1
</em>
<em>y=6x-1
</em>
<em>Substituting this value in second equation 4x-6y=-11 </em>
<em>we get </em>
<em>4x-6(6x-1) = -11
</em>
Answer:
B
Step-by-step explanation:
The conduct of a survey is part of the plan process. In particular, the execution of the question(s) and the responses.
Answer:
Step-by-step explanation:
<u>Factorize both numbers:</u>
- 900 = 2*2*3*3*5*5
- 270 = 2*3*3*3*5
<u>Common factors are:</u>
<u>So HCF is:</u>
- HCF(900, 270) = 2*3*3*5 = 90
