Answer:
Step-by-step explanation:
We are asked to find (f+g)(x). The question is essentially asking us to find the sum of f(x) and g(x).
We know that f(x) equals 3x-1 and g(x) equals x+2. Substitute the values of the functions in.
Combine the like terms.
- 3x and x are like terms (both have the variable "x"
- -1 and 2 are like terms (both without variables, also known as constants)
(f+g)(x) is equal to <u>4x+1</u> and the correct answer is A.
Answer:
The metric system is a system of measurement that uses the meter, liter, and gram as base units of length (distance), capacity (volume), and weight (mass)
Step-by-step explanation:
The metric system uses units such as meter, liter, and gram to measure length, liquid volume, and mass, just as the U.S. customary system uses feet, quarts, and ounces to measure these.
In addition to the difference in the basic units, the metric system is based on 10s, and different measures for length include kilometer, meter, decimeter, centimeter, and millimeter. Notice that the word “meter” is part of all of these units.
Answer:
y = 9
Step-by-step explanation:
Calculate the slope m of line k using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (5, 8) and (x₂, y₂ ) = (2, y)
m = 
= 
Given a line with slope m then the slope of a line perpendicular to it is
= - 
The slope of line l is m = 3, thus slope of line k is
m = - 
Equating the 2 slopes for line k
= - ( multiply both sides by - 3 )
y - 8 = 1 ( add 8 to both sides )
y = 9
Answer: 1400 students
Explanation:
Total = 4000
Senior = 1/8 x 4000 = 500
Senior not in favor of debate = ( 1 - 1/5) x 500 = 400
Non senior = 4000 - 500 = 3500
Non-senior not in favor of debate = (1 - 5/7) x 3500 = 1000
Total = 400 + 1000 = 1400
Answer:
x=±sqrt (33)
Step-by-step explanation:
y=(x+2)(x-2)
29=x^2-4. x^2=33, x=±sqrt (33)
