Answer:
-8
Step-by-step explanation:
plug it into a calculator. its taking 7 away from an already negative number.
A) -2
a slope of a line perpendicular is it’s opposite and reciprocal.
Therefore you want to find the slope. You can do this by writing it in intercept form, or just knowing A/B since it’s in standard form.
slope form: y= mx + b
8y = -4 -4x
y = -1/2x -1/2
So the slope is -1/2 so it’s opposite and reciprocal would be 2. So a slope of a line perpendicular is -2.
b) -1/2
A line parallel would have the same slope as your equation. Since you know the slope -1/2 you know whatever your b value is, that line would be parallel as long as it has the same slope.

09:30 AM i hope this helps! :)
Step-by-step explanation:
10:20 -20 minutes = 10:00 - 19 minutes = 09:41 - 11 minutes = 09:30
Answer:
Ans is 59
Step-by-step explanation:
46 +51+y=180 (sum of triangle)
y=180-46-51
y=83
now,
83+x+38=180
x=180-83-38
x=59
value of x is 59
