Answer:
Hannah needs 10 gallons of soda and 15 gallons of fruit drink
Step-by-step explanation:
Let
x -----> the number of gallons of soda needed
y ----> the number of gallons of fruit drink needed
we know that
-----> equation A
-----> equation B
Solve the system by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (10,15)
see the attached figure
therefore
Hannah needs 10 gallons of soda and 15 gallons of fruit drink
Answer:
y=0.012x+0.65
Step-by-step explanation:
And again y=mx+c
we have 4 point given in the question
(50,1.25) ( 100,1.85) ( 150,2.45) (200,3.05)
we can find the M ( gradient/Slope) by using 2 of them with the formula
I am using the first 2 (50,1.25) ( 100,1.85)
which in decimal form is 0.012
with that cross out the first option as its wrong
now to find c, like in the previous two question, put the m, x and y in the equation and solve for C
I am gonna use the 3rd coordinates for this one (150,2.45)
2.45=0.012(150)+c
2.45=1.8+c
0=1.8-2.45+c
-c=-0.65
c=0.65
So our completed equation is y=0.012x+0.65
The third answer is correct :)
