Part A- C
Part B-4 days
Part C- i got that part wrong
Answer:
Step-by-step explanation:
g(x) = -2x - 4
f(-2x -4)
5(-2x - 4) + 7
-10x - 20 + 7
-10x - 13
Answer:
The product of 5/ 12 and –420 should have been the value of x.
You have to solve for 1 variable
I'm pretty sure they want 4y and not just y becaseu taht is too easy
-6x+4y=33
5x+18y=29
solve for 1 variable
may be messy
-6x+4y=33
add 6x both sides
4y=33+6x
divide both sides by 4
y=(33+6x)/4
sub that for y in other equation
5x+18((33+6x)/4)=29
5x+9(33+6x)/2=29
5x+(297+54x)/2=29
(10x/2)+(297+54x)/2=29
times both sides by 2
10x+297+54x=58
297+64x=58
minus 297 both sides
64x=-239
divide both sides by 64
x=-239/64
sub back
y=(33+6x)/4
y=(33+6(-239/64))/4
y=(33-717/32)/4
y=(1056/32-717/32)/4
y=(339/32)/4
y=339/128
the solution is

you can graph it and check if you want
47/5=9.40
9*5=45
47/5= 9 2/5
