I'm horrible at this so I'm just guessing.
X is the variable and x means multiplication symbol.
X + (X x 3 - 1) + (X x 3 - 1) - 4) <span>≥ 45 is the answer I got.
The answer to that inequality would be
X </span><span>≥ 7 I think.</span>
Answer:
y = x + 1
Step-by-step explanation:
Answer:
38.5 = x
Step-by-step explanation:
9/ (x+2) = 2/9
Using cross products
9*9= 2(x+2)
Distribute
81 = 2x+4
Subtract 4 from each side
81-4 = 2x+4-4
77= 2x
Divide each side by 2
77/2 = 2x/2
38.5 = x
The area of the circle is 16*16*pi=256pi. We can calculate 3/4 of the circle's area for the part not represented by the triangle and the shaded area, and then add in the triangle. 3/4 of the circle's area is 192pi.
The triangle is a right triangle with two legs of length 16. Therefore, it's area is 16*16/2=128, and the total area is 192pi+128, or 731.2.
Thé vertex of the graph of the following function f(x)=x2+8x-2 is (-4,-18).
