-2 is the slope of the line

Remark
Line slopes are found with the formula
m = (y2 - y1)/(x2 - x1)

Givens
y2 = 1
y1 = - 7
x2 = -1
x1 = 3

Sub and solve
m = (1 - - 7) / (-1 - 3)
m = (1 + 7) / -4
m = 8 / - 4
m = - 2

Find the inverse of

y = \left( \dfrac 1 5 \right)^x

For the inverse we swap x and y and solve for y.

x = \left( \dfrac 1 5 \right)^y

Taking logs base 1/5

\log_{1/5} x = y

f^{-1}(x) = \log_{1/5} x

Answer: Second Choice

Note: There's more simplification to do but we'll stop here.

(2, 12), (4, 7), (5, 4) Will the correlation coefficient for these data points be positive or negative?
maw [93]
(2,12)  , (4,7)  -> coefficient is negative, because the x-coordinate is increasing and y-coordinate is decreasing

(4,7),  (5,4)  ->  coeficien is negative too - look above

At the sewing store, Eva bought a bag of mixed buttons. She got 64 large buttons and 16 small buttons. What percentage of the bu
DIA [1.3K]

Answer:

80% of the buttons were large.

Step-by-step explanation:

Recall that percentages are fractions.

We first need to find the total number of buttons that Eva bought

64 + 16 = 80

Then we need to divide 64 into 80 as a fraction of the whole (80 is our whole)

64 ÷ 80 = 0.8

To convert our decimal to a percentage, we must multiply it by 100.

0.8 * 100% = 80%

Therefore, 80% of the buttons were large.

A restaurant offers a​ $12 dinner special that has 77 choices for an​ appetizer, 1010 choices for an​ entrée, and 44 choices for
krok68 [10]
<span>280 I'm assuming that this question is badly formatted and that the actual number of appetizers is 7, the number of entres is 10, and that there's 4 choices of desserts. So let's take each course by itself. You can choose 1 of 7 appetizers. So we have n = 7 After that, you chose an entre, so the number of possible meals to this point is n = 7 * 10 = 70 Finally, you finish off with a dessert, so the number of meals is: n = 70 * 4 = 280 Therefore the number of possible meals you can have is 280. Note: If the values of 77, 1010 and 44 aren't errors, but are actually correct, then the number of meals is n = 77 * 1010 * 44 = 3421880 But I believe that it's highly unlikely that the numbers in this problem are correct. Just imagine the amount of time it would take for someone to read a menu with over a thousand entres in it. And working in that kitchen would be an absolute nightmare.</span>
