Answer:

The average rate of change between -1 and 2 is 1.

Step-by-step explanation:

To get this, use the two ordered pairs (-1, 5) and (2, 8). Now use the slope formula to find the rate of change.

m(slope) = (y2 - y1)/(x2 - x1)

m = (8 - 5)/(2 - -1)

m = 3/3

m = 1

1. Which are true of x = log10 31,500? Select all that apply.

ziro4ka [17]

Given:

$x=\log_{10}31,500$

To find:

Select the true statements from the given options about the given value.

Solution:

We have,

$x=\log_{10}31,500$

It can be written as

$x=\log_{10}(2^23^25^37)$

$x=\log_{10}(2^2)+\log_{10}(3^2)+\log_{10}(5^3)+\log_{10}(7)$ $[\because \log(ab)=\log a+\log b]$

$x=2\log_{10}2+2\log_{10}3+3\log_{10}5+\log_{10}(7)$

$x=2\left(0.30105\right)+2\left(0.47712\right)+3\left(0.69897\right)+0.8451$

$x=4.49835$

Clearly, the value of x lies between 4 and 5. So, $x>4$ and $x$ .

Therefore, the correct options are C and D.

i need help on math

dolphi86 [110]

X=2
2x-3=-x+3

add three to both sides
add 1x to each side
should be left with 3x=6
divide both sides by 3 to get x alone
your answer then is x=2

Write a ratio and a percent for the shaded area.

nika2105 [10]

I’m pretty sure it’s 36/100 - 36% since there are 100 boxes and 36 of them are shaded
