WITCHER [35]

maple syrup = x

corn syrup = 50-x

6x + 0.8(50-x)=2.36*50

6x+40-0.8x=118

5,2x=78

x= 15 gallons of maple syrup

50-15 = 35 gallons of corn syrup

A quadrilateral-shaped land property is drawn on a coordinate grid. Two adjacent sides of the property lie along the lines y = 4

Liono4ka [1.6K]

Answer:

P(-4,-8)

Step-by-step explanation:

Given two lines:

$y = 4x + 8;$ and $ \\y = -0.25x - 9$

To determine the point of intersection P of the lines, we equate the two lines and solve for (x,y).

$4x + 8= -0.25x - 9\\4x+0.25x=-9-8\\4.25x=-17\\$Divide both sides by 4.25$\\x=-4\\$Recall:$\\y = 4x + 8\\=4(-4)+8\\=-16+8\\=-8$

Therefore, the intersection point P of the lines is: P(-4,-8)
