Which is the graph of y = 2.5x? A. B. C. D.

1 answer:

5 0

The answer is D. because first you got solve the problem.

y=2.5x
(turn y to 0)
0= 2.5x
÷2.5 ÷2.5
_________
0=x

So we got one answer (0,0)

y=2.5x
(turn x to 0)
y= 2.5(0)
y=2.5

(2.5, 0)

When you do (0,0) (2.5,0) on the graph it will look like D.)

Answer:

x = (√6)/10^0.7 ≈ 0.488737

Step-by-step explanation:

It can work reasonably well to take antilogs first.

$\log(6)-2\log(x)=1.4\\\\\dfrac{6}{x^2}=10^{1.4}\\\\\dfrac{6}{10^{1.4}}=x^2\\\\x=\dfrac{\sqrt{6}}{10^{0.7}}\approx0.488737$
