If $P(x) = 4+2\sqrt{x+2}$ and $G(x) = 4-3x$, then what is the largest constant $a$ such that $P(G(a))$ is defined?
If the first term of an arithmetic sequence is 17 and the common difference is 6, what is the first term.
In the diagram below, $WXYZ$ is a trapezoid such that $\overline{WX}\parallel \overline{ZY}$ and $\overline{WY}\perp\overline{ZY}$. If $YZ = 12$, $\tan Z = 1.5$, and $\tan X = 3$, then what is the area of $WXYZ$?
A painting with dimensions 10 inches by 14 inches is placed in a picture frame (of constant width), increasing its area to 221 square inches. How many inches is the width of the picture frame?
Let a^2=16/44 and b^2=(2+sqrt5)^2/11, where a is a negative real number and b is a positive real number. If (a+b)^3 can be expressed in the simplified form [x*sqrt(y)]/z where x, y, and z are positive integers, what is the value of the sum x+y+z?
The operation $*$ is defined for non-zero integers as follows: $a * b = \frac{1}{a} + \frac{1}{b}$. If $a+b = 9$ and $ a \times b = 20$, what is the value of $a*b$? Express your answer as a common fraction.
\(f(x) = \frac{3x - 7}{x + 1}\)
x+1=0
x=-1
(-inf, -1)U(-1, inf)
At first I had misread the question. I corrected the answer.
Sorry
So you can find the formula.
I checked the results with Excel.
In the line 4x+ 7y + c = 0, the sum of the a- and y- intercepts is 22 . Find c.
