Answer:
a is 100 b is 5
Step-by-step explanation:
a is 100 because if you substitute 100 for a and 1 for x (decrease of 5 dollars) you get 600 yearbooks sold which is a curate according to the economics class prediction
b is 5 because substituting 5 into b and 1 to x gives you 45 dollars per year book. this is accurate because a 5.dollar decrease in price makes the year books 45 dollars instead of 50
Answer:
between 108-110?
Step-by-step explanation:
60% or 200 = 120 people
90% of 120 = 108
question doesnt look complete so this is the best I could come up with...♀️
I believe the answer is $8.76!
The vendor sold 124 sodas and 90 hot dogs.
Step-by-step explanation:
Let,
x be the number of sodas.
y be the number of hot dogs.
Total sold = 214
According to given statement;
x+y=214 Eqn 1
y= x-34 Eqn 2
Putting value of Eqn 2 in Eqn 1;

Dividing both sides by 2;

Putting x=124 in Eqn 2;

The vendor sold 124 sodas and 90 hot dogs.

This is an example of a
sine wave function. A given sine wave function has a standard form of:
y = A sin [B (x + C)] + D
Where,
A = absolute value of
amplitude
2 π / B = the period of
the sine wave
D = is the midline of y
C = phase of the sine
wave
Rewriting the given
equation into this form will yield:
f (x) = -7 sin[4 (x – π / 4)]
+ 2
Therefore from this form,
we can get the answers:
Amplitude = 7
Period = 2π / 4 = π / 2
