Answer:
x = 41.5
Step-by-step explanation:
2x = 83
x = 83/2
x = 41.5
Answer:
x = 5 and y = 1 is the answer.
Step-by-step explanation:
(-5)(x+4y=1)
(-4)(-3x-5y=-10)
-5x + -20y = -5
12x + 20y = 40
———————
7x + 0 = 35
7x= 35
7x/7 = 35/7
x = 5
subtitution:
x= 5
x + 4y = 1
5 + 4y = 1
4y = 1 - 5
4y = 4
4y/4 = 4/4
y = 1
Answer:
congruent and perpendicular
Step-by-step explanation:
Answer:
D.
Step-by-step explanation:
First, you multiply 18 1/4 with 10 1/2 and you get 191 5/8. Then you multiply 191 5/8 with 12 3/4 and you get D. 2443 7/32
Answer: 
Step-by-step explanation:
By definition, the slope of the line is described as "Rate of change".
You need to use the following formula to calcualte the slope of the line;

In this case you know that the line passes through these two points: (8, -10) and (-6, 14).
Then, you can say that:

Knowing these values, you can substitute them into the formula for calculate the slope of a line:

Finally, you must evaluate in order to find the slope of this line. You get that this is:
