Answer:

y=2x-9 or D

Step-by-step explanation:

To get the slope of the perpendicular line, you find the negative reciprocal.  The negative reciprocal of -1/2 is 2.

Then, you need to find the y-intercept.  Considering the line has to pass through the point (2,-5), you can use the slope to find that the y-intercept is -9.

Answer:

3/2 cm/s

Step-by-step explanation:

speed = gradient of the line (slope)

To calculate the slope divide the change in y by the change in x:

(9 - 0) / (6 - 0) = 9/6 = 3/2 cm/s

Which function is increasing?? :)
exis [7]

Answer:

\large\boxed{B.\ f(x)=4^x}

Step-by-step explanation:

Exponential function f(x)=(a)^x is

increasing if a > 1\to a\in(1,\ \infty)

decreasing if 0 < a < 1\to a\in(0,\ 1)

A.\ f(x)=\left(\dfrac{1}{4}\right)^x\to a=\dfrac{1}{4}\in(0,\ 1)\to\text{decreasing}\\\\B.\ f(x)=4^x\to a=4\in(1,\ \infty)\to\text{increasing}\\\\C.\ f(x)=(0.4)^x\to a=0.4\in(0,\ 1)\to\text{decreasing}\\\\D.\ f(x)=\left(\dfrac{1}{2}\right)^x\to a=\dfrac{1}{2}\in(0,\ 1)\to\text{decreasing}

2 nights. 2/3 plus 2/3 is already more than 1 whole, so he finishes reading one book in 2 days. Since he also reads four books, but also 2/3 of it in one day, the answer still remains the same: 2 nights. Hope this helps! Please rate brainiest answer!
