So it’s saying the X value is -4 so the new equation would be
Answer: 3*-4^2+ 2*-4

-4^2= -16

3*-16+2*-4

3*-16=-48

-48+2*-4=

2*-4= -8

-48+ -8= -56

Answer:

  • both are linear functions with a y-intercept of 3 and domain of all real numbers
  • f(x) has positive slope, so a range of all real numbers
  • g(x) has zero slope, so a range of only the value 3

Step-by-step explanation:

Both functions are shown in the attached graph. Both are linear functions with a y-intercept of 3. Both have a domain of all real numbers.

Function A has a positive slope, so has a range of all real numbers.

Function B has a zero slope, so its range is the single number y = 3.

A group of 485 people take a canoe trip. They fill up all avalible canoes that each hold 3 people with 273 people. The rest of t
Jobisdone [24]
Answer:
3c=273
c=91
2c= 212
C= 106
c= 91+ 106= 197
so they will need 197 canoes total

Why:
So first you have to determine a set variable to represent the number of canoes, I chose C. Then you make an equation to represent the number of canoes 273 people will use if they group into 3's, from this I got 3c=273. Solve for C and get 91.
The remainder of the group which is 485-273= 212 will use canoes in groups of 2's. To represent this, 2c=212. Solve for C and get 106. Combine 106 and 91 to get the total number of canoes.
