For any value of x the value of the expression (x–3)(x+7)–(x+5)(x–1) is equal to –16.
Step-by-step explanation:
In order to prove the statement we can take any value of x and then solve the expression to see if it equal to -16 or not.
So,
Taking x = 2
Taking x = 5
Taking x= 10
Hence,
For any value of x the value of the expression (x–3)(x+7)–(x+5)(x–1) is equal to –16.

Part A you can figure out that the car is traveling at 50 miles an hour because after every hour the distance decreases by 50
b the average change is 100 miles for every 2 hours, which can be simplified back to 50mph which represents the speed of the car
part C {y=-50x+900| (0,900),...(18,0)
since all sides are equal, which means all angles must also be equal to one another
all angles =60°
solving 7x-3=60
7x=63
x=9
similarly 11 y+5=60
11y=55
y=5
Answer:
y=80 I'm pretty sure lmk if it's wrong
Answer:
(5, 2), (5, 1), (2, 1), (2, 2)
Step-by-step explanation:
When rotated 90° CCW about the origin, a point is transformed by the rule ...
(x, y) ⇒ (-y, x)
Your points get transformed to ...
(2, -5) ⇒ (5, 2)
(1, -5) ⇒ (5, 1)
(1, -2) ⇒ (2, 1)
(2, -2) ⇒ (2, 2)
