I got 39 tables.
134+167=301
301/7=43
Total amount of people =344
344/9=38.222 which you would round to 39 tables

What can you say about the y-values of the two functions ?

Both exponential i.e 5 ^x
A is true, surprisingly. 
B cannot be true, it alternates.(rule of indices negatives by positive exponent = positive, negative by negative , but -5 x -5 x -5 = + 5)
I'm only imaginging, but C must be right, since it increases exponentially, as opposed to D which only increases quadratically.

lesya [120]

Answer:

3.53 km

Step-by-step explanation:

Let third day be X:

Second day: X - 0.98

First day: X - 0.98 + 1.37 = X + 0.39

X + X - 0.98 + X + 0.39 = 10

3X = 10.59

X = 3.53 kn

GUYS I NEED HELP ITS URGENT! WILL MARK BRAINLIEST!
Ad libitum [116K]

Answer:

k = 13 The smallest zero or root is x = -10

===============================

Work Shown:

note: you can write "x^2" to mean "x squared"

f(x) = x^2+3x-10

f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5

f(x+5) = (x^2+10x+25)+3(x+5)-10

f(x+5) = x^2+10x+25+3x+15-10

f(x+5) = x^2+13x+30

Compare this with x^2+kx+30 and we see that k = 13

Factor and solve the equation below

x^2+13x+30 = 0

(x+10)(x+3) = 0

x+10 = 0 or x+3 = 0

x = -10 or x = -3

The smallest zero is x = -10 as its the left-most value on a number line.

Hope this was Right
