Ontem = 1/2 h = 0,5 h = 30 min
hoje = 4 h + 1/3 h = 1 h + 60/3 = 1 h e 20 min = 80 min

30 min + 80 min = 110 min

110 min.................54
60 min....................x

11x = 54*6
11x = 324
x = 324/11
x ~ 29,45 por hora

<h3>Answer:   f(x) = x + 13 </h3>

This is the same as y = x+13

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

Explanation:

Let's find the slope

I'll use the first two rows as the (x1,y1) and (x2,y2) points

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

m = (19-18)/(6-5)

m = 1/1

m = 1

The slope is 1.

Now apply the point slope formula and solve for y

y - y1 = m(x - x1)

y - 18 = 1(x - 5)

y - 18 = x - 5

y = x-5 + 18

y = x + 13

f(x) = x + 13  is the final answer

As a check, note how something like x = 5 leads to...

f(x) = x+13

f(5) = 5+13 ... replace x with 5

f(5) = 18

We see that x = 5 leads to f(x) = 18. That verifies the first row. I'll let you check the remaining three rows.

The equation y = x+13 has slope 1 and y intercept 13.

nekit [7.7K]

Answer:

Step-by-step explanation:

Ted had 5 apples weighing 7¼

7¼×5=?

29/4×5=116/4

116/4=29 ounces

Robin had 6 apples weighing 6½

6½×6=?

13/2×6=78/2

78/2=39 ounces

Difference = 39-29=10 ounces
