The value of m must be 4 and the value of b must NOT be -3.
No matter what numbers they involve, two equations with the SAME slope (m) and a DIFFERENT y-intercept (b) have no solution. This is because they form parallel lines, never crossing and therefore never giving a solution.
Answer:
All real numbers
Step-by-step explanation:
There is no real number that makes the expression undefined, therefore the domain would be all real numbers.
Like the given triangle is an isosceles triangle, the value of ∠ABC is 72°.
<h3>Types of Triangles</h3>
There are 3 main classifications for triangles refer to its sides.
- Equilateral triangle - This triangle presents all sides with the same dimensions and the all angles equal to 60°.
- Isosceles triangle - This triangle presents two sides with the same dimensions and it has two angles with equal size.
- Scalene triangle - This triangle presents all sides with different dimensions and it has all angles no equal size.
The figure shows that the given triangle is an isosceles triangle because it has two equal sides (AB=AC). If it is an isosceles triangle, this triangle presents two sides with the same dimensions (AB=AC). and it has two angles with equal size(∠ACB=∠ABC).
Knowing the sum internal angles of triangle is 180°. You can write:
3x+6x+6x=180
15x=180
x=12
Like ∠ABC=6x, then ∠ABC=6*12=72°.

Answer:
Larger cell 400 times bigger cell than the smaller cell
Step-by-step explanation:
Given:
diameter of the cell h = 
diameter of the cell v =
To Find:
How many tines larger is the bigger cell than the smaller cell?
Solution:
The cell h with diameter
is larger and the cell v with diameter
is small. To find the number of times it is larger, we can divide the larger cell diameter by smaller cell diameter
=>
=>
=>
=>
=>
=> 400
Larger cell is the bigger cell than the smaller cell by 400 times
Start with the brackets. Then do 5 multiply 1 which is 5 then divide that 5 from 20 which gets you 4. Times the outside of the brackets with the inside which will give you the answer of 16
