Answer:

see below

Step-by-step explanation:

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

= (90-80)/(0-1)

= 10/-1

=-10

The slope is -10 ft/s

This means the height decreases 10 ft for every second that passes

This is not proportional because it has to go through the point (0,0)

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

= (1000-0)/(3-0)

= 1000/3

=1000/3

The slope is $1000/3

This means the 1000 dollars is sold every 3 days

This is proportional because it goes through the point (0,0) and has a constant slope

Step-by-step explanation:

Let 'm' be slope

HAWK DIVING TOWARDS PREY:

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

= (90 - 80) / (0 - 1)

= 10 /- 1

= - 10

This is not proportional because it doesn't to go through the point (0, 0)

BOOK SALES:

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

= (1000 - 0) / (3 - 0)

= 1000/3

This is proportional because it goes through the point (0, 0)

Hope this helps!

Find the value of x which satisfies the following equation. log2(x−1)+log2(x+5)=4

weqwewe [10]

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \: x = 3$

____________________________________

$\large \tt Solution \: :$

$\qquad \tt \rightarrow \: log_{2}(x - 1) log_{2}(x + 5) = 4$

$\qquad \tt \rightarrow \: log_{2} \{(x - 1)(x + 5) \} = 4$

[ log (x) + log (y) = log (xy) ]

$\qquad \tt \rightarrow \: ( x - 1)(x + 5) = {2}^{4}$

$\qquad \tt \rightarrow \: {x}^{2} + 5x - x - 5 = 16$

$\qquad \tt \rightarrow \: {x}^{2} + 4x - 5 - 16 = 0$

$\qquad \tt \rightarrow \: {x}^{2} + 4x -21 = 0$

$\qquad \tt \rightarrow \: {x}^{2} + 7x - 3x - 21 = 0$

$\qquad \tt \rightarrow \: x(x + 7) - 3(x + 7) = 0$

$\qquad \tt \rightarrow \: (x + 7)(x - 3) = 0$

$\qquad \tt \rightarrow \: x = - 7 \: \: or \: \: x = 3$

The only possible value of x is 3, since we can't operate logarithm with a negative integer in it.

$\qquad \tt \rightarrow \: x = 3$

Let f(x) = x^2 – 81. Find f–1(x). Can someone double-check what I have?

Trava [24]

I hope this helps you

y=x^2-81

x^2=y+81

x=square root of y+81

f^-1 (x)= square root of x+81

9 1/2 divided by 3 7/10

OleMash [197]

Solution:

Convert the fractions into improper fractions and solve.

9 1/2 ÷ 3 7/10
=> 19/2 ÷ 37/10
=> 19/2 x 10/37
=> 19 x 5/37
=> 95/37

Convert the fraction into mixed fraction (Not required):

=> 95/37 = 37/37 + 37/37 + 21/37
=> 1 + 1 + 21/37
=> 2 + 21/37
=> 2 21/37

The solution to the problem is 2 21/37.
