First we are going to express both equation in terms of

to compare their slopes:
For our first equation:



For our second equation:


So now we have our system of equations in terms of y:

Notice that the slope, the coefficient of

, in both equations is the same: 1, and if tow linear equations have the same slope, they are parallel.
We can conclude that we can classify the system of equations as
parallel.
Answer:
To find your heart rate you would, D. 220 - your age
Step-by-step explanation:
You can calculate your maximum heart rate by subtracting your age from 220. For example, if you're 45 years old, subtract 45 from 220 to get a maximum heart rate of 175. This is the average maximum number of times your heart should beat per minute during exercise
Answer:
X=2
Step-by-step explanation:
Ratios
4:x = 24:12
24:12 reduced is 2:1
Therefore we can see x must be half of 4.
So the answer is 2
Hope this helps! :)

Answer: x = 6.56
Step-by-step explanation: -0.4x - 0.5 + x = 3.63
-0.4x^2 - 0.5 = 3.63
-0.4x^2 = 4.13
0.63x = 4.13
x = 6.56
7+2=2+6 because 7+2=8 and 2+6 is = to 8 as well
