replace the value of x int eh equation

so 23x-1 becomes

23(1.1478)-1

23*1.1478 = 26.3994-1 = 25.3994

THE ANSWER IS 8 :)

Step 1: Simplify. Turn 2^3x-1 into 2^3(1)

Step 2: Multiply exponents. 3 times 1 is 3 so it simply becomes 2^3

Step 3: Solve. Multiply 2 by itself three times. By doing this, you get 8!

2x2x2=8

Write in slope-intercept form an equation of the line that passes through the points (−1,12) and (1,2).

zzz [600]

Answer:

$y=-5x+7$

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

the points (−1,12) and (1,2)

substitute

$m=\frac{2-12}{1+1}$

$m=\frac{-10}{2}$

$m=-5$

step 2

we know that

The equation of the line in slope intercept form is equl to

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$m=-5$

$point\ (1,2)$

substitute in the linear equation and solve for b

$2=-5(1)+b$

$b=2+5=7$

therefore

$y=-5x+7$

URGENT Match each ratio of the volumes of two solids to the pair of solids it represents.

Anarel [89]

1. cylinder to cone:
(πr^2h)/((1/3)πr^2h) = 3:1

2. sphere to cylinder:
((4/3)πr^3)/(πr^2h) = 4r:3h

3. cone to sphere:
((1/3)πr^2h)/((4/3)πr^3) = h:4r

4. hemisphere to cylinder:
half the ratio of sphere to cylinder = 2r:3h
