If you already have an equation, all you have to do is locate the slope and look after it. But if it's in a graph, it's where the line is crossing the y-axis.
An example of the equation would be
y=2x+3
y=mx+b
2 would be m which is slope
and 3 would be b which is the y-intercept
If you let j, c, t represent the prices of jeans, camisoles, and t-shirts, respectively, the three purchases can be described by ...
2j +2c +4t = 90.00
1j +0c +3t = 42.50
1j +3c +2t = 62.00
It is convenient to let a calculator solve these equations. It can tell you the row-reduced matrix equations are ...
[[1 0 0 24.5]
[0 1 0 8.5 ]
[0 0 1 6 ]]
which means
flare jeans cost $24.50
camisoles cost $8.50
T-shirts cost $6.00
Answer:
The y-intercept is 4 so you start at 4 on the y-axis. The move down 1 over 5 to get the negative part of the slope.
Step-by-step explanation:
The expression representing the height of the box is x+1.
<h3>What is volume of cuboid?</h3>
The volume of the box is the product of length, breadth and width.
The volume of the box = l x b x h
x³ + 5x² -8x - 12 = (x + 6) . (x -2) .h
= (x²+ 4x -12) .h
h = (x³ + 5x² -8x - 12) / (x²+ 4x -12)
On dividing we get
h = x +1
Therefore, the expression representing the height of the box is x +1.
