If (x+2) is a factor of 3x^2+14x+k, the equation must equal zero when x=-2 so:
3(-2)^2+14(-2)+k=0
12-28+k=0
-16+k=0
k=16
Answer:
The answer is B, f(x)=5(2/5)^(z)
Step-by-step explanation:
I did the graphs for all of them and graph B was identical to the one in the picture.
8a + a - 3 = 6a - 2a - 3
1. Add the a's on both sides:
9a - 3 = 4a - 3
2. Shift 4a to the left and -3 to the right of the equals sign (this changes their signs):
9a - 4a = -3 + 3
3. Simplify:
5a = 0
So a = 0
Answer:
A5 is approximately 5.8 by 8.3 inches in size, and it's the closest in size to the U.S. paper size called the “half-letter” size, at 5.5 by 8.5 inches. But here's how all the A-series sizes break down: A0 paper is 841 by 1189 millimeters, approximately 33.1 by 46.8 inches.A5 measures 148 × 210 millimeters or 5.83 × 8.27 inches. In PostScript, its dimensions are rounded off to 420 × 595 points.A5148 x 210mm5.8 x 8.3 inch
