So r+c=42
c=4+r
subsitute c=4+r for r in r+c=42
r+4+r=42
add like terms
2r+4=42
subtract 4 from both sides
2r=38
divide both sides by 2
r=19
rob=19
subsitute r=19 for r in c=4+r
c=19+4
carly=23
Answer:
b)
Step-by-step explanation:
b) set up equations so they are equal to each other,
this is when f(x)=g(x) so our approximation was close.
c)solving it graphically is nearly impossible because the solution can be any value around the intersection. only way to be sure is to solve it symbolically.
Answer:
Quadratic
Step-by-step explanation:
It looks like it’s forming a very wide arch so quadratic formulas are arches
Is their suppose to be a picture ?
Answer:
terms: 3 terms, 4e,7e, and 5
like terms: 4e and 7e
coefficients:4e and 7e
constants:5
Step-by-step explanation:
terms are the numbers and or variables being added
like terms consist of the same variables
coefficients are the numbers being multiplied by a variable
constants are any numbers that aren't being multiplied by a variable
