The input is the x-coordinate and the output is the y-coordinate. If the input is 4, plug 4 into the x variable to find the output, y.
y=3(4)-5
y=12-5
y=7
The output is 7.
Answer:
45 oz
Step-by-step explanation:
first you need to find the are of the yard. To do that you multiply the length by the width: 60x90=5400 feet
next you divide by 120: 5400/120=45
therefore, you need to buy 45 ounces of grass seed.
The answer is D. 5^-2 times 5^4.
Explanation:
When the points are plotted on a graph, it is easy to see that the slope of AC is -2 and the slope of BC is 1/2. These slope values have a product of -1, so the corresponding line segments are perpendicular to each other.
___
If you have studied vectors, you can find the dot product of AC with BC:
AC = (-5, 3) -(-2, -3) = (-3, 6)
BC = (6, 1) -(-2, -3) = (8, 4)
The dot product is ...
(-3, 6)·(8, 4) = (-3)(8) + (6)(4) = -24+24 = 0
When the dot product of vectors is zero, they are perpendicular.
