Vicki ate 5/20 cookies on Friday and 15/20 last week
Answer:
- 1 1/14 seconds
- 4 2/7 seconds
Step-by-step explanation:
We are being asked for times, so we can express the rate in terms of seconds per meter.
(15 seconds)/(14 meters) = (15/14) seconds per meter = 1 1/14 seconds/meter
__
1) It will take Robot A 1 1/14 seconds to go 1 meter.
2) it will take Robot A 4 2/7 seconds to go 4 meters. (4 times as long)
The quadratic equation is given by:
y = 3x² + 10x - 8
The standard equation of a parabola is given by:
y = ax² + bx + c
Where a, b, c are constants
At point (4, 80):
80 = a(4)² + b(4) + c
16a + 4b + c = 80 (1)
At point (-3, -11):
-11 = a(-3)² + b(-3) + c
9a - 3b + c = -11 (2)
At point (-1, -15):
-15 = a(-1)² + b(-1) + c
a - b + c = -15 (3)
Solving equations 1, 2 and 3 simultaneously gives:
a = 3, b = 10, c = -8
Therefore the quadratic equation becomes:
y = 3x² + 10x - 8

Answer:
Yes!
The rate can be expressed by the ratio 3:1
For every 3 bottles, its $1
For every 6 bottles, its $2
For every 12 bottles its $4
and for every 18 bottles its $6
The juice's are equivalent because the ratio of number to bottles to dollars is equal.

Answer:
5
Step-by-step explanation:
The leading coefficient belongs to the term with the largest exponent
Given
5
- 7x³ + 2x + 1 ← in standard form
The leading term is 5 ← with leading coefficient 5
