<span>In order for an equation to have an infinite number of answers, the simplified equation should be x=x. In evaluating the above equation, -3 inserted in the box results in this simplified equation. The answer is therefor #1: -3</span>
Answer:
The shape of this graph is similar to a U-shape, opening upward
Step-by-step explanation:
Since the coefficient of x^4 is positive and is 1, the function f(x) opens upwards.
Answer:
y=45-3x
Step-by-step explanation:
we want y, which is the number of hours left. to find this, we take:
hours left=total # of hours required - hours worked/day
so:
y=45-3x
(because x could be any number: 2 days, 3 days, etc.)

Answer:
1.646×10¹¹ km³.
Step-by-step explanation:
From the question given, we obtained the following information:
Radius (r) = 3400 km
Volume (V) =.?
The shape of a planet is spherical in nature. Thus, we shall apply the formula for calculating the volume of a sphere to obtain the volume of Planet Mar as illustrated below:
Radius (r) = 3400 km
Pi (π) = 3.14
Volume (V) =.?
Volume of a sphere = 4/3 πr³
V = 4/3 × 3.14 × (3400)³
V = 4/3 × 3.14 × 3.9304×10¹⁰
V = 1.646×10¹¹ km³
From the calculations made above, the volume of Planet Mar is 1.646×10¹¹ km³
