Answer:
Option B. After 20 minutes, Shari had 6 kilometers left to run
Step-by-step explanation:
Let
x ----> the time in minutes
y ----> the distance remaining in kilometers
we have the ordered pair (20,6)
That means
x=20 min
y=6 km
so
After 20 minutes, Shari had 6 kilometers left to run
Answer:
Question 2
Step-by-step explanation:
2) The time when she woke up was - 3° C

125,000×1.05⁷ ≈ 175,888
Answer:
The standard form of the equation for the conic section represented by 
is:
Step-by-step explanation:
We know that:
is the standard equation for an up-down facing Parabola with vertex at (h, k), and focal length |p|.
Given the equation
Rewriting the equation in the standard form
Thus,
The vertex (h, k) = (-5, 12)
Please also check the attached graph.
Therefore, the standard form of the equation for the conic section represented by is:
where
vertex (h, k) = (-5, 12)
Answer:
To solve an equation you can use PEMDAS, standing for parenthesis, exponents, multiplication, division and addition. If it's an equation like, x/3+7+13, you could use the distributive property. By separating variables.
