Answer:
41 empty chairs.
Step-by-step explanation:
Banquet has (22)(4) tables and (15)(6) tables, subtracted by 3.
22 x 4 = 88
15 x 6 = 90
178 - 3
175 chairs.
Subtract 175 by 134 and you have the amount of empty chairs.
41 chairs.

Find Slope:
--------------------------------------------------------------------------------------------------------
y = 1/4x - 7
Slope = 1/4
Perpendicular slope = -4 (Negative reciprocal)
--------------------------------------------------------------------------------------------------------
Substitute slope into the general equation y = mx + b:
--------------------------------------------------------------------------------------------------------
y = -4x + b
--------------------------------------------------------------------------------------------------------
Find y-intercept:
--------------------------------------------------------------------------------------------------------
at point (-2, -6)
-6 = -4(-2) + b
-6 = 8 + b
b = -6 - 8
b = -14
--------------------------------------------------------------------------------------------------------
Substitute b = -14 into the equation:
--------------------------------------------------------------------------------------------------------
y = -4x + b
y = -4x - 14
--------------------------------------------------------------------------------------------------------
Equation:
--------------------------------------------------------------------------------------------------------
y = -4x - 14
y + 6 = -4x - 8 \\add 6 to both sides
y + 6 = -4(x + 2) \\Take out common factor -4
--------------------------------------------------------------------------------------------------------
Answer: y + 6 = -4(x + 2) (Answer D)
--------------------------------------------------------------------------------------------------------
For this case, the first thing we must do is define a variable.
We have then:
t: number of years
P (t): number of people since 2010
We know that:
1) There were 30,700 people in the city
2) The population is growing at a rate of 850 people per year.
The equation modeling the problem is given by:
Answer:
a formula for the city's population is:
Answer:
m < 1200
Step-by-step explanation:
0.10m + 130 < 250
-130 -130
0.10m < 120
/0.10 /0.10
m < 1200
Answer:
-7
