Robin works as a customer service representative. She knows that the
amount in dollars of her yearly bonus is represented by the expression - 1.25x + 651, where x is the
number of complaints customers had about her during the year. To find her bonus if she gets 12
complaints, she substitutes 12 for x. What should be her next step? What would her bonus be?
Answer:
multiply -1.25 x 12
Sense a negative and a positive will always be negative when dealing with multiplication you'll get -15
now -15 +651= 636
always take the sign of the biggest number.

A ride sharing company offers two options: riding in small cars that can carry up to 3 passengers each, or riding in large vans that can carry up to 6 passengers each. A group of 27 people is going to use the ride sharing service to take a trip. The trip in a small car costs $10 and the trip in a large van costs $15. The group ends up spending $80 total. An equation that represents one of the constraints is 3x+6y=a. What is the value of a?
Answer:
a = 27
Step-by-step explanation:
3x + 6y = a
From the given information, 3 and 6 are the numbers of passengers that cars and vans can take. That means x and y must be the numbers of cars and vans, and a is the total number of passengers.
a = 27

Which equations are true for x = –2 and x = 2? Select two options x2 – 4 = 0 x2 = –4 3x2 + 12 = 0 4x2 = 16 2(x – 2)2 = 0
The equation x² - 4 = 0 and 4x² = 16 have roots of x = -2 and 2 so option 1st and 4th are correct.
What are the roots of an equation?Roots of an equation are the solution of that equation, since an equation consists of hidden values of the variable so to determine them by different processes and then the resultant is called roots.
For example root of x -4 = 0 is x = 4 so 4 will be the only root of this linear equation.
The number of roots of an equation depends on the degree of the equation for example number of roots of quadratic equation are 2.
Given the roots
01)
x = -2
square both sides
x² = 4
x² - 4 = 0
02)
x = 2
Square both sides
x² = 4
Multiply by 4 on each side
4x² = 16
Hence "The equation x² - 4 = 0 and 4x² = 16 have roots of x = -2 and 2".

Three interior angles of a polygon are 125,140 and 160. The remain angles are 145 each. Calculate the sum of the interior angles of the polygon
Answer:
1440 degrees.
Step-by-step explanation:
125 + 140 + 160 = 425 degrees.
The remaining angles are each 145.
The exterior angles of all polygons sum to 360 .
So we have exterior angles sum of the 3 given angles
= (180-125) + ( 180-140) + (180-160)
= 55 + 40 + 20 = 115.
So the remaining vale of the sum is 360 - 115
= 245 degrees.
An internal angle of 145 will give an external one of 35 degrees.
245/35 = 7.
So there are 7 145 degree angles in the polygon.
Sum of the interior angles is therefore:
425 + 7*145
= 1440 degrees.
This is a 10 sides polygon ( a decagon).
