Answer:
y=3.5x
Step-by-step explanation:
Since when x is 0 when y is 0, there is no y-intercept. The ratio with the other values gives the equation y=3.5x, because y is 3.5 times larger than x.
<span>b. 2πn this sounds like the right awnser to me

Answer:
x=1
Step-by-step explanation:
3=5x-4+2x
collect the like terms
3=7x-4
Move terms
-7x=-4-3
Calculate
-7x=-7
Divide both sides by -7
x=1
Answer:
4, -2
Step-by-step explanation:
1+1=2
2-2=0
0+3=3
so on
+1,-2,+3,-4,+5,-6...

it is a way of remembering how to multiply binomials
it tells which terms to multiply
example
(x+3)(x+4)
First (multiply first terms)
x times x=x²
Outer (multiply outer terms)
x times 4=4x
Inner (multiply inner terms)
3 times x=3x
Last (multiply last terms)
3 times 4=12
now add them all
x²+4x+3x+12
x²+7x+12
that is what FOIL is
