Answer:
14. C
15. C
Step-by-step explanation:
14. The function is entirely in quadrants I and II, so the leading coefficient is positive. This eliminates choices A and B.
The horizontal asymptote is 0, not -1, eliminating choice D.
The curve is best described by the equation of choice C.
__
15. The domain and range of an unadulterated exponential function are ...
domain: all real numbers; range: y > 0 . . . . matches choice C
Answer:
a. infinite solutions, answer is x = 30, identity equation
b. no solution, a contradiction equation
c. no solution, a contradiction equation
Step-by-step explanation:
Its -3 or 3 sorry if you get it wrong if its not tight.
<span>A) 12x + 15y = 34
</span><span>
</span><span>B) -6x + 5y = 3 Multiplying B) by -3
</span>
B) 18x -15y = -9 Then adding this to A) equals
30x = 25
x =

0.8333333333...

<span>A) 12x + 15y = 34
</span>
12 * <span>
<span>
<span>
0.8333333333... + 15y = 34
</span></span></span><span><span><span>
</span></span></span><span><span><span /></span></span>10 + 15y = 34
15y = 24
y = 1.6

He is incorrect. If you divide 520 by 10 you get 52. He is correct for that answer. But 23.160 divided by 10 is 2.316. NOT 23.10.
