Answer:
x = −
7
Step-by-step explanation:
y = 4.5*x^2-9*x+8.5;4.5;-9;8.5
-(((-9)^2-(4*4.5*8.5))/(4*4.5))
-(-9/(2*4.5))
4.5*0^2-(0*9)+8.5
(7*x^5-(5*x^7))^(1/2)+1/((7*x^5-(5*x^7))^(1/2))
Answer:
8246=x+180
x=8066 miles
Step-by-step explanation:
Let the initial readings be x
The final reading is the sum of initial reading and distance covered hence
Final=Initial + distance covered
Substituting 8246 miles for the final miles and 180 miles for the distance traveled to Grandma's house
8246=x+180
Solving for x
x=8246-180=8066 miles
D and b maybe... (I’m not super sure though)
Really ! What are you going to do when the moment comes
on an exam when you have to do it on your own ?
<u>(1/4) (8x + 16) = -10</u>
Multiply each side by 4 :
8x + 16 = -40
Subtract 16 from each side:
8x = -56
Divide each side by 8 :
<u>x = -7</u>
C is the answer. The height of a cylinder is the perpendicular distance between the bases.
