Answers:
- slope = 2
- slope = -3
- slope = 1
- slope = 1/4
- slope = 1/4
None of the five lines are horizontal or vertical
===============================================
Explanation:
Something like f(x) = 2x-5 is the same as y = 2x-5. This is because y = f(x).
Compare y = 2x-5 with y = mx+b. We see that m = 2 is the slope in this case.
The other four questions are handled the same way.
A horizontal line occurs when the slope is 0. Since none of the slopes are zero, none of the lines are horizontal.
A vertical line equation is of the form x = k, where k is any real number. The y variable is not involved. It is not possible to write a vertical line equation in the form y = mx+b because the slope m is undefined. So none of the given five equations are vertical lines.
Side note: something like y = x+6 is the same as y = 1x+6

Answer:
26.8cm²
Step-by-step explanation:
the area if a rectangle is 53.6cm^2.If the length is multiplied by four and the width is halved, the area would then be?
Area of rectangle = length x width
53.6 = 4L x 1/2 W
53.6 = 2L × W
Divide both sides by 2
L × W = 53.6 ÷ 2
New area = 26.8cm²

Answer:
Step-by-step explanation:
Part A
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
1) radius = diameter/2 = 4/2 = 2 inches
Volume = 3.14 × 2² × 10 = 125.6 inches³
2) Volume = 3.14 × 20² × 50 = 62800 cm³
3) radius = 16/2 = 8 mm
Volume = 3.14 × 8² × 10 = 2009.6 mm³
4) Volume = 3.14 × 9² × 9 = 2289.06 ft³
Part B
The formula for determining the volume of a sphere is expressed as
Volume = 4/3πr³
Where
r represents the radius of the sphere.
5) Volume = 4/3 × 3.14 × 5³ = 523.3 cm³
6) radius = 24/2 = 12 inches
Volume = 4/3 × 3.14 × 12³ = 7234.56 inches³
7) Volume = 4/3 × 3.14 × 1³ = 4.2 ft³
8) radius = 42/2 = 21 mm
Volume = 4/3 × 3.14 × 21³ = 38772.72 mm³
