Which inequality below will have a dashed boundary line with a shaded area above its graph? A. 7x − y ≤ 3 B. x − y ≤ 4 C. 2x − 9y > 2 D. 4x + 7y > 3
Answers
Now turn your inequalities into y = mx + b form
2x - 9y > 2 --- subtract 2x from both sides
-9y > -2x + 2 -- divide by -9...and change inequality sign
y < 2/9x - 2/9 this says y is less then.....we need greater then...this is not it
try the next one...
4x + 7y > 3 --- subtract 4x from both sides
7y > 4x + 3 -- divide by 7
y > 4/7x + 3/7
this says y is greater then...this is the one we want

Which statement is true about a line and a point? A point and a line have length as a dimension to measure. A point is a location and a line has many points located on it. A line and a point cannot lie on the same plane. A line and a point cannot be collinear. 2. Trisha drew a pair of line segments starting from a vertex. Which of these statements best compares the pair of line segments with the vertex? The line segments and the vertex have length as a dimension of measurement and there are three collinear points on each. Line segments and the vertex have two endpoints each and the distance between the end points is their dimension. Line segments have two endpoints and a vertex is a common endpoint where two line segments meet. The line segments and the vertex have their lines extending in one direction only and the lengths of both are infinite.

What is Area of Circle?
A circle's area is the area that it takes up in a two-dimensional plane.
The formula for area of circle is, A = πr², where r is the radius of the circle. The unit of area is the square unit, such as m², cm², etc.
Given:
Radius= 40 mm
So, Area of petri dish = πr²
= 3.14x(40 mm)²
= 3.14 x 1600 mm²
= 5024 mm²
and, Population Density
= 2100 / 5024
= 0.418 bacteria per mm²
Hence, the population density is 0.418 bacteria per mm².

Area = πr^2
= 3.14•(40 mm)^2
= 3.14•1600 mm^2
= 5024 mm^2
Pop Density = 2100 / 5024
= 0.418 bacteria per mm^2
The answer is 0.42 bacteria per square mm

Answer:
ok sorry i could not put this into a formula im have to go but i will show you a really easy way.
Step-by-step explanation:
for number 1 i got (7,-1)
This is because there is a slope of 1/1 between these two points. so i plotted the two points on the graph. The distance between the two points is 4. so i followed the slope 4 times and thats what i got.
The correct way for doing number 1 is using the distance formula i believe but im running out of time
for the second one i got (3, -1/2)
we do this by using the midpoint formula.
The first picture is for number one and the second for number 2

SA of cone = pi×r×l + pi×r²
= pi×r×(3r) + pi×r²
= 3pi×r² + pi×r²
= 4pi×r²
SA of cylinder = 2pi×r×h + 2pi×r²
= 2pi×r×2r + 2pi×r²
= 4pi×r² + 2pi×r²
= 6pi×r²
