answer:
x=-1, y=0
step-by-step explanation:
y= -7x-7, y= 5x+5
substitute−7x−7for y=5x+5:
y=5x+5
−7x−7=5x+5
−7x−7+−5x=5x+5+−5x(add -5x to both sides)
−12x−7=5
−12x−7+7=5+7(add 7 to both sides)
−12x=12
-12x/-12=12/-12 (divide both sides by -12)
x=−1
substitute−1 for x in y=−7x−7:
y=−7x−7
y=(−7)(−1)−7
y=0(simplify both sides of the equation)
answer: x=−1 and y=0
good luck :)
hopefully, this helps
have a great day !!
Answer:
(3, -9)
Step-by-step explanation:
To reflect an image across the line y = x, (x, y) → (y, x).
(-9, 3) → (3, -9)
Ok so 3cm/1m so 25 m times 3 cm is the answer so the answer is 75 cm
1 over 117649 is equivalent to (7^3)^-2
