Answer:
x = 14
Step-by-step explanation:
-1/5(x - 4) = -2
-1/5x + 4/5 = -2
-1/5x = -2 - 4/5
-1/5x = -10/5 - 4/5
-1/5x = - 14/5
x = -14/5 * - 5
x = 70/5
x = 14 <====

Answer:
We conclude that the person is saving $60 dollars per week.
Hence, option C is true.
Step-by-step explanation:
Given the table chart
Week Saving Money
2 60
4 120
6 180
8 240
We know to determine the slope to find the rate of change.
Taking the points (2, 60) and (4, 120)
Rate of change = Slope = [y₂ - y₁] / [x₂ - x₁]
= [120 - 60] / [4 - 2]
= 60 / 2
= $30 dollars per week
Now, taking the points (4, 120) and (6, 180)
Rate of change = Slope = [180 - 120] / [6 - 4]
= [60] / [2]
= $30 dollars per week
Now, taking the points (6, 180) and (8, 240)
Rate of change = Slope = [240 - 180] / [8 - 6]
= [60] / [2]
= $30 dollars per week
- This concludes that the rate of change is contant i.e. $30 dollars per week
Therefore, we conclude that the person is saving $60 dollars per week.
Hence, option C is true.
Answer:

Step-by-step explanation:

Firstly, we've to interchange the variables.

Solving for y

Adding 3 to both sides

Multiplying 2 to both sides

Taking cosine on both sides

Dividing both sides by y

Replace y by 
=> 
Answer:
d. 6.99
Step-by-step explanation:
You have a right triangle with the right angle marked.
The hypotenuse is opposite the right angle and has no length given.
For the 25-deg angle, the side with length 15 is the adjacent leg, and the side with length x is the opposite leg.
The trigonometry ratio that relates the opposite leg to the adjacent leg is the tangent ratio.


Solve for x by multiplying both sides by 15.


Use a calculator to find the value of x.
