the lines are perpendicular because they're crossing each other
Answer:
3,158
Step-by-step explanation:
The formula is :
h(x)=-49(x)-125
h(-67)=(-49)*(-67)-125
h(-67)=3283-125
h(-67)=3158
The value of x is 5. Angle one and four are vertical. You can do this by writing 7x = 3x + 20. Isolate the variable by moving 3x to the other side. If you do this, 3x becomes negative, and you end up with 7x-3x = 20 --> 4x = 20.
x=5.
