Answer:
about 30.1 astronomical units or 4.5 billion kilometers.
Answer:
Marla did 64 sit ups each day for one week = (60*7)+(4*7)= 448
Marla did 64 sit ups each day for one week =(50*7)+(14*7)= 448
Marla did 64 sit ups each day for one week =(40*7)+(24*7)= 448
Step-by-step explanation:
Marla did 64 sit ups each day for one week = 64 *7 = 448
A distributive property allows us to multiply a sum by multiplying each addend separately first and then summing the products together.
64 sit ups could be written as 60+4, 50+14 or 40+24.
Apply the distributive property:
Marla did 64 sit ups each day for one week = (60*7)+(4*7)= 448
Marla did 64 sit ups each day for one week =(50*7)+(14*7)= 448
Marla did 64 sit ups each day for one week =(40*7)+(24*7)= 448
We can try any two numbers whose sum is 64 and all will give us the answer 448....
We have been given Marley was asked to solve 
using the Quadratic Formula. She found the discriminant first and decided she did not need to continue with the Quadratic Formula.
We are asked to determine whether Marley is correct or not.
We know when an equation is in form 
, we can use discriminant to check for the real solutions of equation.
If 
, then the equation will have two real solutions.
If 
, then the equation will have one real solution.
If 
, then the equation will have no real solutions.
Let us find discriminant.
Since 
, therefore, the equation will have no real solutions, so Marley is correct.
Answer:
(-4, 3)
Step-by-step explanation:
There are coordinate rules for reflection that really help me with these:
Reflection over x-axis -- (x, y) -> (x, -y)
Reflection over y-axis -- (x, y) -> (-x, y)
Reflection over y = x -- (x, y) -> (y, x)
Reflection over y = -x -- (x, y) -> (-y, -x)
Hope this helps :]
The x-axis is probably time, so look at the horizontal line when it's value is five, and determine which line is higher at five seconds.
