Answer:

Y= -1/4x - 1

Step-by-step explanation:

we know that the equation of the line is:

y=mx+b

m= slope= (y2-y1)/(x2-x1)

we have two points giver from the graph:

point 1: (-4,0)

point 2: (4,-2)

we to find the slope:

m=(-2-0)/(4-(-4))

m=-2/8

m=-1/4

we need to find "b"

using the point (-4,0)

we have:

0=(-1/4)*(-4)+b

0=1+b

so we have b=-1

finally we have that the answer is:

y=-1/4x-1

snow_tiger [21]

yeet


first brand quantity is x

2nd brand quantity is y


x+y=30

0.3x+0.55y=0.35(30) or 0.3x+0.55y=10.5

solve for x and y

multiply first equation  by -0.3

-0.3x-0.3y=-9

add to 2nd equation


0.3x-0.3y=-9

<u>0.3x+0.55y=10.5 +</u>

0x+0.25y=1.5


0.25y=1.5

divide both sides by 0.25

y=6

sub back

x+y=30

x+6=30

x=24


you need 24 gallons of the first brand and 6 gallons of the 2nd brand
