Answer:
A and B
Step-by-step explanation:
A line is a distance between two points. The possible equation of the line will be g(x) = 4x - 7
<h3>Equation of a line</h3>
A line is a distance between two points. The equation of a line in slope-intercept form is expressed as y = mx + b
where:
- m is the slope
- b is the y-intercept
Given the equation of the line graphed by Chin expressed as f(x) = 4x + 3, the equation similar the line must have the same slope. The possibe equation of the line will be g(x) = 4x - 7

Step-by-step explanation:
the surface area is the area that describes the material that will be used to cover a geometric solid. To find the volume of the prism we multiply the area of the base, called the base area B, by the height h.
Answer:
1.5secs
Step-by-step explanation:
Given the expression that models the height as;
h(t) = -16t²+20t +6
The ball will touch the ground at when h(t) = 0
0 = -16t²+20t +6
Swap
-16t²+20t +6 = 0
Divide through by -2
8t²-10t-3 = 0
Expand using the general formula
t = -(-10)±√(-10)²-4(8)(-3)/2(8)
t = 10±√100+96/16
t = 10±√196/16
t = 10±14/16
t = 10+14/16
t = 24/16
t = 1.5
Hence it will take the ball 1.5secs to hit the ground
