Answer:
v > -25/p
r = -5 +7/3 w
Step-by-step explanation:
- pv + 40 < 65
Subtract 40 from each side
- pv + 40-40 < 65-40
-pv < 25
Divide each side by -p (remember to flip the inequality since we are dividing by a negative)
-pv/-p > 25/-p
v > -25/p
7w - 3r = 15
Subtract 7w from each side
7w-7w - 3r = 15-7w
-3r = 15-7w
Divide by -3
-3r/-3 = (15-7w)/-3
r = -5 +7/3 w
Complement angles, sum is equal 90
Give one angle = 70 to find other: 90 - 70 = 20
Answer
Complement of angle with the measure of 70 degrees is 20 degrees
Independent is hour
Dependent is her rate ($18) because it DEPENDS on how long she works
Answers:
a. £2,090
b. My answer would be less because my total in euros would be divided by a greater number when converting euros to pounds.
Work for part a:
Apartment: 560•3= 1680 euros
Car: 20.16•15= 302.4 euros
1680+302.4=1982.4
1982.4/1.12 = £x/1
1982.4 / 1.12= £1,770
£1,770 + £320 = £2,090 total
Work for part b:
Example:
(instead of 1.12 I put 2 to see what would happen with a greater number)
1982.4 / 2 = 991.2
991.2 is less than 1,770 (the answer I got with 1.12)
Let me know if you need any clarification! :)
Since adding a constant to a function simply moved the graph upwards by that amount, solve f(x) for any value and see how much the graph given is different from that value of y...the simplest way in this case may be to simply find f(0) which is:
5*2^0=5
Clearly the graph at x=0 is at y=-2 so we can see that k is:
5+k=-2 so
k=-7
