Answer:
a. 226 pounds
b. 8 weeks
Step-by-step explanation:
To solve this problem, simply plug in the numbers for the variables it told you they correspond to. 12 is the number of weeks, and t represents the number of weeks, so we can plug 12 in for t.

Simplify and you'll have your answer.

For part B, 234 is the amount of pounds, and W represents the weight in pounds, so we can plug 234 in for W.

3 hours, 6.5/ per hour therefore 6.5x3= 19.5 and with the additional fee of 1.25, 19.5+1.25= 20.75
Answer: Choice A) -3
Work Shown:

Which leads us to choice A. In the second step, I used the rule that
is equivalent to
. For each equation, the b is the base. Note how logs undo exponents and vice versa.
Answer:
Two points on the graph would be (2,-1) and (4,2).
Step-by-step explanation:
You can choose two random x variables such as how i selected 2 and 4. if you change the variable x to those values you can solve for y or in this case f(x).
EX:
3/2*2-4
6/2-4
3-4
f(x)= -1
Answer:
x = 10
, y = 10
Step-by-step explanation:
using the sine and cosine ratios in the right triangle and the exact values
cos60° =
, sin60° =
, then
cos60° =
=
=
( cross- multiply )
2x = 20
( divide both sides by 2 )
x = 10
and
sin60° =
=
=
( cross- multiply )
2y = 20
×
= 20
( divide both sides by 2 )
y = 10
