Answer:
There intersecting lines
Step-by-step explanation:
5x+2y=-8
-5x -5x
2y=-8 -5x
/2 /2 /2
y=-4 -5/2x also
y=-5/2x - 4
&
y=5/2x - 19
neither parallel (slope is not the same)
or perpendicular (slope is not reciprocal or opposite signed)
hope i helped

Formula
---------------------------------------
Volume = πr²h
---------------------------------------
Find Volume of one tank
---------------------------------------
Volume of 1 tank = πr²h
Volume of 1 tank = 3.14 x 6² x 12
Volume of 1 tank = 678.24 ft³
---------------------------------------
Find Volume of 5 tanks
---------------------------------------
Volume of 1 tank = 678.24
Volume of 5 tanks = 678.24 x 5
Volume of 5 tanks = 3391.2 ft³
---------------------------------------
Answer: 3391.2 ft³

Answer:
Step-by-step explanation:
Given equation is representing the graph of parabola which opens down and its pick is its vertex
<u>The vertex is calculated by vertex formula:</u>
- x = -b/2a for the equation y = ax² + bx + c
<u>In our case t is the vertex and its value is:</u>
- t = -42/(-1.5*2) = 42/3 = 14 seconds
