Answer:

8 feet

Step-by-step explanation:

First, we need to look at the relationship between the elephant and its shadow. The elephant is 9 ft tall and the shadow is 3 ft long, making the elephant 3 times larger than the shadow. Using this information, we can assume that the tree is 3 times larger than its shadow. To find the answer, divide 24 by 3, giving you a final answer of 8 feet long.

24 / 3 = 8

Evaluate f(x) = -4x + 7 when x = 2 and x = -2.
anzhelika [568]

Answer:

f(x)=-1 and 15

Step-by-step explanation:

What you do is you put -2 and 2 into the x.

f(x) = -4(-2) + 7 = -1

f(x) = -4(2) + 7 = 15

f(x)=-1 and 15 are your answers.

Please anybody help please
wel

Answer:

x= -3 and y = 6

Step-by-step explanation:

so basically what you are trying to do is reduce into finding x and y

what you do is you want to find a number to multiply one of the equations in order to get the same x or y value does not matter which

so,...

we can do

either 20x or 15y

we will go with the smallest 15y

so for both equations multiply the whole thing by 5 for the first equation and by 3 for the second

5 x 5x+3y=3 --> 1

3 x 4x+5y=18 --> 2

we then get

25x+15y = 15 -->1

12x + 15y = 54 -->2

then now that you have the same Y values you can subtract ! which cancels out both the 15y

25x+15y = 15 -->1

- 12x + 15y = 54 -->2

13x =-39

so now x=-3 and all you have to do with x = -3 is sub this into either one of the equations that you started with  !

x = -3

5(-3) +3y =3

-15 + 3y = 3

3y = 3+15

3y=18

y = 6!

_30. Solve the following logarithmic equation: log8(x + 9) + 3 = 3
Bezzdna [24]

Answer:

A

Step-by-step explanation:

using the rule of logarithms

log_{b} x = n ⇒ x = b^{n}

log_{8} (x + 9) + 3 = 3 ( subtract 3 from both sides )

log_{8} (x + 9) = 0 , then

x + 9 = 8^{0} = 1 ( subtract 9 from both sides )

x = - 8
