Answer:
False.
Step-by-step explanation:
To determine the inverse of a function, we first write the parent function in terms of y. So, in this part the x would be isolated to one side of the equation. Then, with the new form of the parent function, we switch the x into y and y to x. The new function would be the inverse function. For the given function, we do as follows:
<span> y=-4/x + 1
y - 1 = -4/x
x ( y - 1 ) = -4
x = -4 / (y -1)
Replacing x into y and y into x,
</span>y = -4 / (x -1)
<span>Therefore, the inverse is y=-a/x-b where a = 4 and b = 1.</span>
70 degrees! This is the answer. Notice that the triangle ACF is isosceles, therefore, 35, 35 degrees, and 110 the vertex at F, then AB is 180 deg, so 70 left!
No, it doesn’t pass the line test
Answer:
n=35; q=33 coins.
Step-by-step explanation:
1) if number of nickles is 'n' and the quaters is 'q' then it is possible to write:
n+q=68 - 'she counted 68 coins...' - the 1st equation of system;
0.25q+0.05n=10 - '10$ in it' - the 2d equation of the system.
2) it is possible to make up and solve the next system of two equations:
