Answer:
y = -x + 3
Step-by-step explanation:
The equation of a line with slope equal to -1 and y-intercept equal to 3 has the form
y = mx + b. With m = -1 and b = 3, we get: y = -x + 3
Think about this problem, please. Is there any way in which you could be clearer about what you wanted to learn?
Hi there.
Thanks for using Brainly!
First, let's rewrite to make this problem easier.
1^2 - a^2b^2
Then we must multiply the terms with equal exponents with their bases.
1^2-(ab)^2
Using the factor: a^2 - b^2=(a-b)(a+b)
We can factor using that expression.
(1-ab) x (1+ab)
After factoring, this has been our solution.
Solution: (1-ab) x (1+ab)

Answer:
17
Step-by-step explanation:
f(x) = 3x + 2
f(5) = 3(5) + 2 = 17
X - the unit
3x; 4x; 5x - the lengths of the sides
3x + 4x + 5x = 30
12x = 30 |:12
x = 2.5
3x = 3 · 2.5 = 7.5 cm
4x = 4 · 2.5 = 10 cm
5x = 5 · 2.5 = 12.5 cm
