Answer:
Step-by-step explanation:
Point-slope equation for line of slope -⅔ that passes through (5, 1):
y-1 = -⅔(x-5)
Rearrange to solve for y:
y = -⅔(x-5)+1
y = -⅔x + 13/3 Slope-intercept form
⅔x + y = 13/3
2x + 3y = 13 standard form
A = P*(1 +r)^t
4614 = P*1.12^18
4614/7.689966 = 600.00
$600 must be deposited to have $4614 after 18 years.
Answer:
Q(-2,-7)
See attachment
Step-by-step explanation:
We need to form a simultaneous equation and solve.
The point P has coordinates (1,8). Let the other point Q also have coordinate (x,y).
Then the average rate of change is the slope of the secant line connecting P(1,8) and Q(x,y) and this has a value of 5.
This point Q also lies on the given parabola whose equation is
Put equation (1) into (2) to get:
When x=-2, y=5(-2)-3=-7
Therefore the required point is Q(-2,-7)
Answer:
The multiples of 20 are
Step-by-step explanation:
1, 20
2, 10
4, 5
You would add the negatives and get a sum of:
-155.
to make it a fraction you just put it over one.
final answer:
-155/1
hope this helped!! xx
