Answer:
y = 3x+6
Step-by-step explanation:
y=3x-2
This is in the form
y = mx+b where m is the slope and b is the y intercept
The slope is 3 so a line parallel also has a slope of 3 since parallel lines have the same slope.
Using slope intercept form
y = 3x+b
We have a point (2,11)
11 = 3*2+b
11 =6+b
11-6 = b
5 =b
The equation is
y = 3x+6
Answer:
first number is 9
second number is 7
Step-by-step explanation:
2x + y = 25
3x - y = 20
Add the two equations so that 'y' is eliminated:
5x = 45
x = 9
2(9) + y = 25
18 + y = 25
y = 7
You are using the 7 to see what the 8 will change to. Because the 7 is over 5 it will round up the 8 and so the answer would be 590
Answer:
9x² -5
Step-by-step explanation:
(f○g)(x) means f(g(x))
Put the definition of g(x) in place of x in the definition of f(x):
f(g(x)) = f(x²) = 9(x²) - 5
(f○g)(x) = 9x² - 5
