4x-2y=8 ==> y=2x-4 (to better show you what I mean)
2 lines are parallel if they have the same slope (m the coefficient of x).
So y=mx + b // y =2x-4 means m=2 & y=mx + b, becomes y=2x + b.
Moreover they are telling us that this function passes by (-2,1), where -2 represents x & 1, represents y. To calculate b , replace x & y by their values:
y=2x+b ==> 1 = 2(- 2) + b==> 1 = -4 + b ==> b= 5. Finally the equation is
y=-2x+5
Answer:9.75
Step-by-step explanation:12x12 =144 and 7x7= 49 subtract 144-49 and get 95 the square root of 95 is approximately 9.747 rounded to the nearest hundredths place is 9.75
Answer: D
You get the same answer from doing both!
69 babyyyyyyyyyyyyyyyyyyyyyy
Answer:
Both Shawn and Brielle are correct. The function that represents a vertical stretch by a factor of 9 is f(x)=9×2.The function that represents a horizontal shrink by a factor of 3 is: f(x)=(3x)2, which is equal to f(x)=9×2.
Additionally, if you wanted to verify that the given points are on the graph of both functions, you could substitute them into the functions to get true statements.
