Answer: C. y=1/3x+3
Step-by-step explanation:
The line hits the y axis at 3 so 3 is the y intercept and the line rises one accross 3 so 1/3 is your slope. Together its y=1/3x+3
Answer:
x = 44°
Step-by-step explanation:
The sum of the exterior angles of any polygon my be 360°, so just add all the angles up, and subtract this from 360°.
Given a pentagon with exterior angles: 102°, 47°, 34°, and 133° with the missing angle x°.
To find the missing angle, first write an equation representing the given rule:
102° + 47° + 34° + 133° + x° = 360°
(316°) + x° = 360°
316° + x° - 316° = 360° - 316°
x° = 44°.
This way, because the rule must be true, the missing angle with this value will satisfy this:
102° + 47° + 34° + 133° + <u>44°</u> = 360°
For this topic, here are some general angle rules for polygons:
- n is the number of sides
- 180° (n – 2) = sum of interior angles of any polygon.
- 180° (n – 2) / n = each interior angle of a regular polygon [all sides and or angles the same measure / congruent].
- 360° = sum of exterior angles of any polygon.
- 360° / n = each exterior angle of a regular polygon. [all sides and or angles the same measure / congruent].
Answer:
Irrational
Step-by-step explanation:
The square root of 28, which is 5.291502622129181, is not a rational number. It cannot be written as a simple fraction, so it is called irrational.
Answer:
(-18, -3)
Step-by-step explanation:
To solve this system of equations, use the substitution method.
Steps for substitution method:
Step 1 : First, solve one linear equation for y in terms of x.
Step 2: Then substitute that expression for y in the other linear equation. You'll get an equation in x.
Step 3: Solve this, and you have the x -coordinate of the intersection.
Step 4: Then plug in x to either equation to find the corresponding y -coordinate.
Answer:-10.2n-1
Step-by-step explanation:
you have: -2.4n+3 and -7.8n+2
Combine like terms.
-2.4n - 7.8n = -10.2n
-3 + 2 = -1
So we have:
-10.2n - 1
In other words-->>
-2.4n-3+-7.8n+2
Simplify them-->>
-10.2n-3+2
-10.2n-1
