Is there a graph ? But I’m thinking z>1
To find inverse of a function, switch x and y
x = (y + 2)/7
7x = y + 2
y = 7x - 2
answer - A. p(x) = 7x - 2
<em>Answer:</em>
<em>In my opinion the answer is </em><em><u>y = 6</u></em>
<em>Step-by-step explanation:</em>
<em>We have two unknowns from the equation therefore, two equations are needed. These equations are:
</em>
<em>
</em>
<em>3x + y = 9 </em>
<em>y = –4x +10 </em>
<em>
</em>
<em>To solve for y, we first substitute the second equation to the first one.
</em>
<em>3x + –4x +10= 9 </em>
<em>x = 1
</em>
<em>
</em>
<em>We substitute the value of x to either of the equations and solve for y.
</em>
<em>
</em>
<em>y = –4(1) +10 </em>
<em>y = 6</em>
Answer: 80,000
Step-by-step explanation:
Plug in 50,000 where the x are and then just solve from there
