Answer:
y=1x+2 or y=x+2
Step-by-step explanation:
We know that the slope is going to be one since the slopes of parallel lines are equal and the other equation has a slope of 1. We can then use the equation y=1x+b and the point given, (2,4), to find the y-intercept, b. You plug in (2,4) as your x and y values to get 4=1(2)+b. You can then solve this by multiplying to get 4=2+b, then subtracting 2 from both sides to get b=2. We can then use b to complete the equation as y=1x+2 or y=x+2.
The whole field is square, and its total area is 25 acres.
It's divided up into 25 little sections.
Each little section is a square, and its area is 1 acre.
So the whole thing looks like a square tray with 25 little square blocks in it.
The blocks are in 5 rows, and there are 5 blocks in each row.
There are 16 blocks around the edge of the square tray, and 9 in the middle
that don't touch the edge.
Every block costs $1,200 to start out. But the ones around the edge are
more expensive. Anything on the edge costs an extra $150 for each side
of the little block that touches the edge.
Most of the 16 little blocks around the outside have only 1 side that touches
the edge. But the ones in the
<em>corners</em> of the tray have 2 sides along the edge.
You may want to have a look at the picture I attached.
That should be plenty to put you in a position to work out the costs.
Answer:
- 3x² + x + 5
Step-by-step explanation:
g(x) + f(x)
= 4x + 5 - 3x² - 3x ← collect like terms
= - 3x² + x + 5
