Answer:
(f+g)(x) = -3x+5
Step-by-step explanation:
f(x)=x+8 and g(x)=-4x-3
(f+g)(x) = f(x) + g(x)
= x+8+-4x-3
= -3x+5
If you would like to solve 4 + 3/5 * (15 + 2x) = 25 for x, you can do this using the following steps:
4 + 3/5 * (15 + 2x) = 25
3/5 * (15 + 2x) = 25 - 4
9 + 6/5 * x = 21
6/5 * x = 21 - 9
6/5 * x = 12 /*5/6
x = 12 * 5/6
x = 10
The correct result would be x = 10.

Natalie was supposed to use PEMDAS (as we all do when doing math), which stands for: Parentheses, Exponents, Mulitplication, Division, Addition, Subtraction. However, Natalie subtracted 1 from 2 before multiplying 6 by 4 and dividing it by 2.
Hope this helps!!
Answer:
Slope in this case is -2
Y-Intercept in this case is 5, or (0, 5)
Step-by-step explanation:
In order to identify the slope and y-intercept, you must put the equation is y = mx + b form. This is quite simple! Don't panic! You got this :)
4x + 2y = 10
Move x to the right
2y = -4x + 10
Divide by y's coefficient
y = -2x + 5
Slope in this case is -2
Y-Intercept in this case is 5
