Answer:
(c) Yes, because angle 3 and angle 6 are congruent
Step-by-step explanation:
Angles 3 and 6 are "alternate interior" angles. When those angles are congruent, as these are, then the lines crossed by the transversal are parallel.
__
We expect angles 5 and 6 to be supplementary because they are a linear pair. That fact says nothing about the relationship of line d to line c.
Answer:
y = -1/4x^2 - x + 3
Step-by-step explanation:
(-6,0)
(-4,3)
(2,0)
36a - 6b + c = 0
16a -4b + c = 3
4a + 2b + c = 0
c = -4a - 2b
36a - 6b - 4a -2b = 0
16a - 4b -4a - 2b = 3
32a -8b = 0
12a - 6b = 3
4a - b = 0
4a - 2b = 1
b = -1
4a + 1 = 0
4a = -1
a = -1/4
c = 1 + 2 = 3
y = -1/4x^2 - x + 3

See Explanation
Step-by-step explanation:
<u>Define the variables</u>
Let the entry fee be c and the hourly rate be m
Let the number of hours be x and the total amount be y
<u>Work to solve</u>
For Sami's skate
and
For Brad's skate
and
<u>The equations</u>
The equation is derived using:
For Sami's skate
For Brad's skate
<u>When the cost are the same</u>
To do this, we equate both expressions
i.e.
i.e. the cost are the same at the 4th hour
<u>What is the cost</u>
Substitute 4 for x in any of the equations
<em>The cost is $14.00</em>
The original equation is x=10×200
Frank and the # of workers hired= # of workers+Frank
x= the total area of the field, not how much each worker has to harvest
10×20=200
9+1=10
10×200=x
Solution: B. Frank and nine workers are hired to harvest tomatoes from a field. If each of the workers is given a plot which is 10 by 20 feet in size,what is the total area of the field?
