Answer:
1. 5 – x = 8 , x = -3
2. -1 = x – 2 , x = 1
3. -3x = 9 , x = -3
4. -10 = -5x , x= 2
Step-by-step explanation:
First, do the distributive property: 4x-5=4x+2
This answer has no real solution. The term is no real numbers.
Just graph it in the calculator
Answer: Like the angles BAC (56°) and BDC has the same arc BC in the circumference, these angles must be congruent, then angle BDC must be equal to 56°.
Let x be the distance (in feet) along the road that the car has traveled and h be the distance (in feet) between the car
and the observer.
(a) Before the car passes the observer, we have dh/dt < 0; after it passes, we have dh/dt > 0. So at the instant it passes the observer we have
dh/dt = 0, given that dh/dt varies continuously since the car travels at a constant velocity.
