Answer:
Average decrease in value per year: $70
Step-by-step explanation:
600 ---> 250
600 - 250 = 350
350 / 5 = 70
Answer:
Reflecting a point across the y-axis -> changes the sign of the x-coordinate
Reflecting a point across both axes -> changes the sign of both coordinates
Reflecting a point across the x-axis -> changes the sign of the y-coordinate
Step-by-step explanation:
Reflections:
- The rule to reflect a point across the y-axis is (-x, y), meaning that the x-coordinate's sign changes.
- Reflecting a point across both axes is the same thing as rotating it 180 degrees, so the rule is (-x, -y). This means that both coordinates' signs change.
- Reflecting a point across the x-axis is (x, -y), meaning that the y-coordinate's sign changes.
Answer:
(a) 117.1 billions of dollars
(b) 187.6 billions of dollars
Step-by-step explanation:
The sales S (in billions of dollars) for walgreens from 2000 through 2010 can be modeled by the exponential function.
where t is the time in years, with t = 0 corresponding to 2000.
(a) In 2014, t = 2014 - 2000 = 14
(b) In 2018, t = 2018 - 2000 = 18
Part 1:
6(x-5) = 5(x+5) (x = 55)
4y + 2 (-3 + 2y) = 1-y (x = 7/9)
Part 2:
4(a-6) = 8a - (4a-24) (No Solution)
4(2x-8) = 8(x-8) (No Solution)
2(3x-3) = -6x-6 (Identity (x = 0))
Answer:
70 Degrees
Step-by-step explanation:
All triangles add up to 180 degrees so add 44+26=70 180-70= 110 so remaining angle is 110. A straight line is 180 degrees so using the remaining angle of the blue triangle we find that 180-110=70 so B is 70 degrees.
