Answer:
y = -1/2x - 3
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Determine known variables
Slope = -1/2 (m = -1/2)
y-intercept - (0, -3), so b = -3
Step 2: Write in known variables
y = -1/2x - 3
For the GCF, you want to perform the title backwards.
Write Factors of the numbers, find the Common ones and then the Greatest of those.
*It is good to write the factors in pairs to ensure none are left out
18
1, 18, 2, 9, 3, 6
27
1, 27, 3, 9
36
1, 36, 2, 18, 3, 12, 4, 9, 6
The factors common in all are 1, 3, & 9
Now, from these numbers, select the greatest - 9
Answer:
3.25 minutes
Step-by-step explanation:
3.25 minutes per green light x 24 = 78
the yellow light is a given, hence 6 cars pass through
78 + 6 = 84 cars
The following inequality in slope-intercept form.
y≤-4x-15
Slope intercept form is y=mx+ c
- m= slope
- c= y intercept
- So, inequality 4x+y≤ – 15 is written as
- y≤-4x-15
- with , m= slope =-4
- c= y intercept= -15
what is a coordinate in geometry?
Coordinates are two numbers (Cartesian coordinates), or every so often a letter and a range of, that discover a particular point on a grid, called a coordinate aircraft. A coordinate aircraft has 4 quadrants and two axes: the x axis (horizontal) and y axis (vertical).
what is coordinate geometry instance?
In coordinate geometry, lines are parallel if their slopes (m) are equal. for instance: the line y = ½ x - 1 is parallel to the line y = ½ x + 1 due to the fact their slopes are both the identical.

Answer:
34 edges
Step-by-step explanation:
Euler's formula for polyhedron states
F + V - E = 2
where F is number of faces, V, number of vertices, E number of edges
Here F = 16, V = 20, thus
16 + 20 - E = 2, that is
36 - E = 2 ( subtract 36 from both sides )
- E = - 34 ( multiply both sides by - 1 )
E = 34
