Answer:
7n is greater than or equal to 21
t4+10
Step-by-step explanation:
Answer:
y ≥ 3x +4
Step-by-step explanation:
The line is solid, so the inequality will include the "or equal to" case. The shading is above the line, so values of y greater than or equal to those on the line are in the solution set. The only choice with the correct (≥) inequality symbol is ...
y ≥ 3x +4
The amount of metal used to make the can = surface area of cylindrical can, which is: D. 42π in².
<h3>What is the Surface Area of a Cylinder?</h3>
A can is a cylinder.
Surface area of a cylinder = 2πrh + 2πr²
Thus:
Amount of metal used to make the can = surface area of the can
r = 6/2 = 3 in.
h = 4 in.
Therefore:
Surface area = 2×π×3×4 + 2×π×3²
Surface area = 24π + 18π
Surface area = 42π in².

A
12x+3y = 36
3y = -12x+36
divide
y = -4x+12
parallel = same slope
so A
Vertices of the triangle located at R(2, 3), S(4, 4), T(5, 0), gives;
Part A:
The lengths of the sides are;
- RS = √5
- RT = 3•√2
- ST = √(17)
Part B;
The slopes are;
- Slope of RS = 1/2
- Slope of RT = -1
- Slope of ST = 4
Part C:
- The triangle is a scalene triangle
<h3>Which method can be used to analyze the triangle?</h3>
Part A: The length of each side can be found using Pythagorean theorem as follows;
Length of RS = √((4 - 2)²+(4 - 3)²) = √5
Length of RT = √((5 - 2)²+(0 - 3)²) = 3•√2
Length of ST = √((4 - 5)²+(4 - 0)²) = √(17)
Part B:
The slope of each side are;
- Slope of RS = (4 - 3)/(4 - 2)= 1/2
- Slope of RT = (0 - 3)/(5 - 2) = -1
- Slope of ST = (4 - 0)/(4 - 5) = 4
Part C: Given that the length of the sides of the triangle are different, (√5, 3•√2, and √(17)), the triangle is a scalene triangle, by definition of scalene triangles.
