4)
a) you got it correct
b) y = 70x
c) Yes
d) f(6) = 70(6) = 420
e) f(x) = 210
70x = 210
x = 210/70
x = 3
f) continuous
g)
Domain: <span>The set of </span>all possible input values<span> (commonly the "x" variable), which produce a valid output from a particular function.
</span> (-∞ , ∞)
Range: <span>The range is the set of </span>all possible output values<span> (commonly the variable y, or sometimes expressed as </span><span><span>f(x)</span><span>f(x)</span></span><span>), which result from using a particular function.
</span>(-∞ , ∞)
5)
a) y = -5x
b) Yes, go thru (0,0)
and Yes, constant rate is -5
c) Yes
d)
f(11) = -5(11) = -55
e)f(x) = -45
-5x = -45
x = 9
Answer:
2/18
Step-by-step explanation:
because i multiplied 1/9 by 2
There are a total of 32 problems.
Assumed all 32 problems are 3 points questions ⇒ 32 x 3 = 96 points.
The test is worth 111 points, so there is an extra of 111-96 points = 15 points.
The difference in points in the 2 type of questions is 4 - 3 = 1 points.
Number of 4 points questions = 15 ÷ 1 = 15.
Number of 3 points questions = 32 - 15 = 17.
Answer: There are 17 3-points questions and 15 4-points questions.
Answer:
-10
Step-by-step explanation:
x+75=180-(x+125)
2x=-20
x=-10
