Answer:
See attachment for graph
Step-by-step explanation:
Given
Required
Draw the graph
First, we identify at least 2 possible values of x and y
Let 
Solve for y
So, a point is: 
Let 
Solve for y
So, another point is: 
<em>Plot </em><em> and </em><em> on the graph, then draw a straight line through both points</em>

Answer:
12566.4 mm²
Step-by-step explanation:
The Petri dish shown has no lid. What is the surface area of the outside of the Petri dish? Round to the nearest tenth. A cylindrical-shaped Petri dish with a radius of 50 millimeters and a height of 15 millimeters.
TSA = Total Surface Area
CSA = Curved Surface Area
TSA of open cylinder = CSA of cylinder + area of base or top
= 2πrh + πr²
= πr(2h + r)
From the above question:
r = 50mm
h = 15mm
Hence,
= π × 50 (2 × 15 + 50)
= π × 50 (30 + 50)
= π × 50(80)
= π × 4000
= 12566.370614mm²
Approximately = 12566.4 mm²
The Surface Area of the petri dish with no lid = 12566.4 mm²
Answer:
.7 or 70%
Step-by-step explanation:
17/30 + 17/25 + 38/50 + 18/25 = 2.727
2.727 divided by 4 (the amount of addends) = .7
2x^2 - 7
we can plug any values of x into this The domain is All Real x.
The graph will be a parabola opening upwards with a minimum value when x = 0 and f(x) will be = -7
so the range is f(x) <= -7 or (-∞, -7]
4(5x - 2) - 2(9 - 3x)
= 26x - 26
