Answer:
$1.65
Step-by-step explanation:
If h is the price of a hot dog, then the total bill was ...
4(2h +1.25) = 18.20
2h +1.25 = 4.55 . . . . . . divide by 4
2h = 3.30 . . . . . . . . . . . subtract 1.25
h = 1.65 . . . . . . . . . . . . . divide by 2
The price of one hot dog was $1.65.
Answer:
D
Step-by-step explanation:
This is because of the slope and amount of earnings Tatiana has.
Tatiana gets 26 dollars added to her earnings every 2 hours
Sample: 16 + 26 = 42
The 16 represents the number of earnings that Tatiana gets/earns for hour 0.
If we were to graph the earnings of Tatiana meaning her time represents X and the earnings represent Y. We could clearly see that Tatiana earns more money than Darryl.

∑3(1/4)ⁿ⁻¹ ==> replace n by consecutive values, starting with 1
ⁿ=¹
f(1) = 3(1/4)⁰ = 3 x 1 (any number raised to o is equal to 1
f(2) = 3(1/4)¹ = 3 x 1/4
f(3) = 3(1/4)² = 3 x (1/4)²
f(4) = 3(1/4)³ = 3 x (1/4)³
f(5) = 3(1/4)⁴ = 3 x (1/4)⁴
And so on and so forth. Then we have found a pattern that is:
f(n) = 3(1/4)ⁿ⁻¹
and with this you can find any number providing you know n
30:42 would be the answer, 30/42 if you’re looking for a fraction
You have the equation 7x+y=5
But you must rearrange this into y=mx+b form
to do this subtract 7x from both sides
y= -7x+5
On the y axis plot a dot on 5 because that is the y intercept.
To find the x intercept let y=0
0= -7x+5
1. Subtract 5 to both sides
-5=-7x
2. Divide by -7 to both sides
x= -5/-7
x=5/7
The x intercept is 5/7, so on the x axis mark a dot on 5/7 which is approximately at 0.7
Once you have marked one dot on the y axis at 5 and another dot on the x-axis at 0.7 then you draw a straight line through these points and you have graphed the function 7x+y=5
