Answer:
$570
Step-by-step explanation:
Given that:
For each hour of tutoring, Lena earns 30 dollars.
E is her earning and
H is the number of hours for which she tutors.
To find:
Equation relating E to H.
Solution:
Let Lena tutors for 1 hour, then the earning = 30 dollars
Let Lena tutors for 2 hours, then the earning = 30+30 OR 230 = 60 dollars
Let Lena tutors for 3 hours, then the earning = 30+30 +30 OR 330 = 90 dollars
If Lena tutors for H number of hours, then the earning, E = 30 + 30 + .... + 30 (H times) i.e.
So, the equation that relates E to H is given as:
Now, it is given that she tutors for 19 hours.
Let us put H = 19 hours in the above equation:
Therefore, the earning for 19 hours of tutoring is <em>570 Dollars.</em>
Answer:
Step-by-step explanation:
slope = (y2 - y1) / (x2 - x1)
(-3,-4)....x1 = -3 and y1 = -4
(-2,r)....x2 = -2 and y2 = r
slope = 10
now sub
10 = (r - (-4) / (-2 - (-3)
10 = (r + 4) / (-2 + 3)
10 = (r + 4) / 1.....multiply both sides by 1, eliminating the 1 on the right
10 * 1 = r + 4
10 = r + 4
10 - 4 = r
6 = r <======
We are given the function <span>–2x – 4 + 5x = 8 and is asked in the problem to solve for the variable x in the function. In this case, we can first group the like terms and put them in their corresponding sides:
-2x + 5x =8+4
Then, do the necessary operations.
3x = 12
x = 4.
The variable x has a value of 4.</span>
