Answer:
(x -11) * t + 1067
Step-by-step explanation:
We know that in her tutoring job she earns x amount of money and how waitress earns $ 11 / hour.
They give us the combined number of hours that he works with all the jobs, which is 97, but from here we can say that in the time that he does NOT work as a tutor it is actually 97 - t.
Total earned this month = x * t + 11 * (97 -t)
Total earned this month = x * t + 1067 - 11 * t = (x -11) * t + 1067
Answer:
a = 5
Step-by-step explanation:
3(a - 4) + 1 = 9 - a Distribute the 3 into a-4
3a - 12 + 1 = 9 - a Combine like terms
[-12 and 1]
3a - 11 = 9 - a Add 11 to both sides to isolate 3a
+11 +11
3a = 20 - a Add a to remove it and have all a
+a +a
4a = 20 Divide by 4 to only have a
/4 /4
a = 5
Answer:
<em>1. We can't see any boat on the river at this scale.</em>
<em>2. 0.025 inches. We won't be able to see it</em>
<em></em>
Step-by-step explanation:
<em>the beginning of the question states that; according to this map, the driving distance is 3 miles, we're most interested in the graphics at the bottom left, which indicates that 1 inches on the map corresponds to 2,000 ft in real life.</em>
<em />
If 1 inches = 2000 ft,
x inches = 50 ft
we cross multiply to give
2000x ft = 50 ft-inches
x = 50/2000 =<em> 0.025 inches</em>
You would use the point-slope equation of y-y₁=mx(x-x₁)
So the rate of change is the slope and equals m, so m=-4
and has a solution at (-5,2) which would be the (x₁, y₁) and then it is just plugging in the numbers
y - (2) = (-4)(x - (-5))
y - 2 = -4 (x+5)
y - 2 = -4x - 20
y = -4x - 18
Answer:
The answer to that question is 7
