Step-by-step explanation:
y = -2x + 1. => Slope = -2
Then the perpendicular line will have a slope of -1/(-2) = 0.5.
We have y = 0.5x + c.
When x = 4, y = -3.
=> (-3) = 0.5(4) + c, c = -5.
Hence the answer is y = 0.5x - 5. (C)

Answer:
> 1
Step-by-step explanation:
A scale factor greater than 1 will produce an enlargement
A scale factor less than 1 will produce a reduction
Since the image is larger than the pre- image the scale factor > 1
Real numbers are all numbers found on the number line (positive, negative, fractions, square roots, whole numbers).
Rational numbers are fractions, or quotients, of two integers.
Irrational numbers are numbers with decimals that continue on (without repetition). They cannot be written as a fraction of two integers. Irrational number examples: √41, √97, √15
Natural numbers are whole, positive numbers.
Integers are whole, non-fraction numbers.
ANSWER: 1/8 is not a whole number, an integer or a natural number. It is a real and rational number (choice #1).
Hope this helps! :)
Answer:
8 seconds
Step-by-step explanation:
lets first start by plugging in 1024 into initial height
h(t) = -16t^2 + 1024
I would find a Greatest Common Factor (GCF) first
-16(t^2 - 64) If this is new just think that if you multiply -16 by t squared and -64 you will come back to the original equation
But now we notice that T squared -64 can be factored with the difference of perfect squared method
so we will get -16(t-8)(t+8)
So to get the answers we will set everything equal to 0
-16t =0
t =0 this is the time that the penny was thrown
t-8 = 0
t = 8 the is the time the penny hit the ground
t+8 =0
t= -8 This is an extraneous solution or a solution that doesn't make sense so we just disregard the solution.
