Answer:
-2
Step-by-step explanation:
replace x with -4 in the h(x) function
h(x) = -2x-10 ➡ h(-4) = (-2)×(-4)-10 ➡8-10 = -2
Answer:
30 first-class tickets were sold and 260 coach tickets were sold.
Step-by-step explanation:
Let a first-class ticket be represented by f and let a coach ticket be represented by c.
On a particular flight, a jumbo jet was carrying 290 passengers. So, the sum of the first-class tickets and coach tickets must sum to 290:
The total income was $95,280. Therefore:
We can now solve the system of equations. First, we can simplify the second equation by dividing everything by 8:
From the first equation, we can subtract f from both sides:
Substitute:
Distribute:
Simplify:
So:
From the previous equation:
Substitute:
30 first-class tickets were sold and 260 coach tickets were sold.
Answer:
you have to find the mean, median, and mode so the 1st is that you have to add numbers and then multiple it
Step-by-step explanation:
did this in 8th grade middle school
We can use the subtraction property of logs to expand the right side of the equation:
log(1/H*) = log(1) - log(H*)
No matter what base we’re using, log(1) = 0, so this simplifies to -log(H*). We’re also given a pH value of 3.6, so we can substitute this value into the original equation along with -log(H*) to get
3.6 = -log(H*)
Multiplying by -1 on both sides:
-3.6 = log(H*)
And rewriting in exponential form:
H* = 10^(-3.6) = 0.0003 (rounded to the nearest ten thousandth)
Answer:$25
