How to represent y=5x+40 with an equation
2 answers:
Y=5x +40
What that is saying is that y equals five times whatever x is +40.
So, if x=1, then y=45
x | y
----------
-2 | 30
-1 | 35
0 | 40
1 | 45
2| 50
To solve these, all I did was plug the number in as x. For example,
If x=2:
y=5(2)+40
y=10+40
y=50
Or, if x=-2:
y=5(-2)+40
y=-10+40
y=30
Well you already have it in alope intercept form
-5x+y=40 is in standard form

it is very easy so focus
Step-by-step explanation:
b is more than a by 90
50 % is half, which means half are not for sale.
The fraction for half is 1/2
Multiply total boats by 1/2 = 33 boats are not for sale.
Dunno C. (Just guessing im not so good at maths)
Ok so we know that x = y+70
So y+y+70 = 300
2y+70 = 300
2y = 230
y = 115
So we know that x = y+70
do x = 115+70
X= 185
C is your possible answer. You are trying to find how many females.
