Answer:
Step-by-step explanation:
First, you must find the actual decrease in temperature.
Decrease = Yesterday's temperature - Today's temperature
Decrease = 80 - 75
Decrease = 5 degrees
Now, find the percentage decrease.
% Decrease = Actual decrease / Yesterday's temperature x 100
% Decrease = 5/80 x 100
% Decrease = 0.0625 x 100
% Decrease = 6.25 %
So, the percent decrease in high temperature from yesterday to today is 6.25%
Answer: Choice C) Infinitely many solutions
If you solve the first equation for y, you get
2y = 14 - 2x
2y = 14 + (-2x)
2y = -2x + 14
2y/2 = (-2x)/2 + 14/2 ... divide every term by 2
y = -x + 7
This result of y = -x+7 is identical to the second equation in the system. So the two graphs are going to be the same. We only produce one line. One graph is right on top of the other. The two lines will intersect infinitely many times. Any point on the blue line is a solution to the system.
Answer:
The answer is
<h2>
</h2>
Step-by-step explanation:
To find the equation of the line given a point and slope we use the formula
<h3>
</h3>
where
m is the slope
( x1 , y1) is the point
From the question the point is (0 , 3) and slope is - 6
Substitute the values into the above formula and solve
That's
<h3>
</h3>
We have the final answer as
<h3>
</h3>

A markdown in math is basically a decrease in whatever numbers you are working with.
Answer:
16
Step-by-step explanation:
If you flip 4 coins there are 16 possible outcomes
You can determine this by doing 
x is 4 in this case
unless you want all the outcomes... I can answer that if you want
