Answer:
Step-by-step explanation:
y-4x=6
y=6+4x, using this value in 2y-3x=4 gives
2(6+4x)-3x=4
12+8x-3x=4
5x+12=4
5x=-8
x= -8/5= -1.6, making y=6+4x become
y=6+4(-1.6)
y= -0.4, so the solution is the point
(-1.6, -0.4)
Answer:
An equation is a mathematical statement that shows the equal value of two expressions while an inequality is a mathematical statement that shows that an expression is lesser than or more than the other. 2. An equation shows the equality of two variables while an inequality shows the inequality of two variables.
Answer:
2394 cubic centimeters
Step-by-step explanation:
If all of the dimensions of the shipping box are 1.3 times that of the gift, then the volume of the box is 1.3^3=2.197 times that of the gift. Dividing this by the volume of the box, you get a volume of 2000 cubic centimeters for the volume of the gift. Subtracting this from the volume of the box, you get 2394 cubic centimeters of unused space. Hope this helps!
