Step-by-step explanation:
just guess and see
We can solve this question by replacing "4 consecutive integers" with 4 expressions.
x
x + 1
x + 2
x + 3
We know that when we add the four expressions together, we will get the answer of 358. So now, we have:
4x + 6 = 358
Subtract 6 from both sides.
4x = 352
Divide 4 from both sides.
x = 88
Our consecutive integers are 88, 89, 90, and 91.
Answer:
(f+g)(x)=f(x)+g(x)=x²+2x+2
Step-by-step explanation:
f(x)=7
g(x)=x²+2x-5
(f+g)(x)=f(x)+g(x)=x²+2x+2

Answer:
The smaller number is -9.
Step-by-step explanation:
Let <em>x</em> and <em>y</em> be the two unknown numbers.
Their sum is -5. Hence:
Their difference is 13. Hence:
This yields a system of equations. We can solve this using elimination. Adding the two equations together:
Simplify:
Divide both sides by two. Thus:
Using either equation (I'll use the first):
So, our two numbers are 4 and -9.
The smaller number is -9.
