Answer: 12 gallons
Step-by-step explanation:
The car uses 16 gallons to travel 240 miles. You need to calculate how many miles is in a gallon. So, divide 240 by 16 (you get 15). That is 15 miles per gallon. Next, you divide 180 by 15 to calculate how many gallons it would take you to travel 180 miles if there are 15 miles in a gallon.
Answer:
First, do 4x*4x. then,16x*16x. next, 64x*64x. and,256x*256x. answer:1024x. Divide 1024x by 8x. answer to that is 128.
F(x) = -(x+7)² + 4
f(x) = -(x+7)(x+7) + 4
f(x) = -(x² + 7x + 7x + 49) + 4
f(x) = -x² - 14x - 49 + 4
f(x) = -x² - 14x - 45
True for f(x)

test 1 = 50
test 2 = 70
70+50 = 120
so tests are .5*120/2 = 30 points
hw = .25*100= 25 points
quiz = .25*75 = 18.75
total score = 30+25+18.75 = 73.75
Answer:
Option 4 : 
Step-by-step explanation:
<u>See the attached figure:</u>
To find the vertices of the feasible region, we need to graph the constraints, then find the area included by them, then calculate the vertices which is the intersection between each two of them.
As shown, the shaded area represents the solution of the constraints
So, the vertices of the feasible region are:
