Evaluate the function.
f(x)=-2x^2-7x+6
Find f(−3)
Answers
Answer:
f(-3) = 9
Step-by-step explanation:
Step 1: Define
f(x) = -2x² - 7x + 6
f(-3) = x = -3
Step 2: Substitute and evaluate
f(-3) = -2(-3)² - 7(-3) + 6
f(-3) = -2(9) + 21 + 6
f(-3) = -18 + 21 + 6
f(-3) = 3 + 6
f(-3) = 9
Substituting x = -3 into the function f(x) = -2x^2 - 7x + 6, we get f(-3) = -33. Therefore, the value of the function at x = -3 is -33.
To evaluate the function f(x)=−2x ^2 −7x+6 at x=−3, substitute −3 for x in the function: f(−3)=−2{(−3) }^2 −7(−3)+6
Now, calculate each part of the expression:
(−3) ^2 is 9 because the square of −3 is 9.
−2 times 9 is −18 because −2⋅9 =−18.
−7 times −3 is 21 because −7⋅−3=21.
Now, plug these values back into the expression:
f(−3)=−18−21+6
Finally, add and subtract:
f(−3)=(−18−21)+6=−39+6=−33
So, f(−3)=−33.
The value of the function
f(x)=−2x^ 2 −7x+6 at x=−3 is −33.

Step-by-step explanation:
Keep in mind that exterior angles are mentioned. So let's find the interior ones. Note that the interior and exterior angles are forming straight lines. So something plus 84 equals 180 degrees.
180-84=96
180-120=60
The sum of three angles of a triangle is 180 degrees. X is an angle. So we can form an equation to represent this. Then just solve for x!
96+60+x=180
156+x=180
x=24

Making a proportion helps solve this problem. Cm on top, km on bottom.
1 9
---- = ----
20 ?
Cross multiply to get 1? = 180
? = 180.
The distance is 180 km.
Final answer:
The conversion of 9 cm on the map to an actual distance, using the given scale of 1 cm for 20 km, results in an actual distance of 180 kilometers.
Explanation:
The question is asking for the actual distance corresponding to 9 cm on the map. According to the given scale on the map, 1 cm corresponds to an actual distance of 20 km. So to find out how many kilometers 9 cm on the map would be in real life, we simply multiply the length measured on the map by the distance each centimeter represents. This gives us:
9 cm * 20 km/cm = 180 km
So, according to the map, 9 cm corresponds to an actual distance of 180 kilometers.

Answer:
The remaining amount in the person's wallet is $30.
Step-by-step explanation:
We are given that a person left the house to go shopping with $240.00 in his wallet, and he spent 2/3 of this amount in the supermarket, then spent 1/4 of what was left in the pharmacy. At a stop at the butcher shop, he left 1/2 than he had left.
And we have to find the remaining money in the wallet after making all these above expenses.
At the starting, the amount of money in the person's wallet = $240
Amount of money spent in the supermarket =
=
= = $160
So, now the amount of money left with him = $240 - $160
= $80
Amount of money spent in the pharmacy =
= = $20
So, now the amount of money left with him = $80 - $20
= $60
Now, Amount of money spent at the butcher shop =
= = $30
So, now the amount of money left with him = $60 - $30
= $30
Hence, the amount of money remaining in the person's wallet is $30.

Step-by-step explanation:
a/(5h+q) = t
multiply both sides by 5h + q
a / (5h + q) * (5h+q) = t * (5h + q)
a = t * (5h + q)
I would say this is your answer.
You could distribute the t
a = 5ht + tq
which could also be an answer.
