I graphed the equation using an online graphing calculator and got the vertex of (-5, 49) therefore y = 49
Y-intercept happens when x = 0
y-intercept represents if Mitch doesn't add the monthly savings, so the savings account will still remain in $175
Their slopes must be the same, but with different y-intercepts.
Here is an example: 2x + 1 and 2x + 4 are parallel lines.
Answer: x(2x²+5)
please give brainliest if it helped
Surface area of a sphere = 4πr²
Surface area of the sphere = 4π(0.8)² = 8.0 ft²
Volume of a sphere = 4/3 πr³
Volume of the sphere = 4/3 π(0.8)³ = 2.1 ft³
Answer: Surface area = 8.0 ft² and volume - 2.1 ft³ (Answer C)
