Answer:

  18, 21

Step-by-step explanation:

Let x represent the smaller number. Then x+3 is the larger number, and the other relation between them is ...

  3(x+3) = (7/10)(5x)

  6x +18 = 7x . . . . . multiply by 2 and simplify

  18 = x . . . . . . . . . . subtract 6x

The two numbers are 18 and 21.

Solve the equation and show all work. 4|x + 1/3| = 20 <br> i'm kind of stuck hhh
34kurt

Absolute value is a function that takes some number and outputs the size of that number, regardless of the sign. By definition, |x|=x if x\ge0, and |x|=-x if x.

For example,

  • |2| = 2 because the input 2 is positive, so the input is unchanged;
  • |-3| = -(-3) = 3 because the input -3 is negative, so the sign is switched.

What this means for this problem is that there are two cases to consider:

  • If x+\frac13\ge0, then \left|x+\frac13\right|=x+\frac13, so that

4\left(x+\dfrac13\right)=20\implies x+\dfrac13=5\implies\boxed{x=\dfrac{14}3}

  • On the other hand, if x+\frac13, then \left|x+\frac13\right|=-\left(x+\frac13\right), so

-4\left(x+\dfrac13\right)=20\implies x+\dfrac13=-5\implies\boxed{x=-\dfrac{16}3}

Can someone help please:<br> let f(x)=x^2+x <br> solve f(x-1)+f(x+1)=6
eimsori [14]

Step-by-step explanation:

f(x)=x^2+x

so

f(x-1) = (x - 1) ^ 2 + (x - 1)

= x^2 - 2x + 1 + x - 1

= x^2 - 3x

and

f(x+1) = (x + 1) ^ 2 + (x + 1)

= x^2 + 2x + 1 + x + 1

= x^2 + 3x + 2

now

f(x-1) + f(x+1) = 6

x^2 - 3x + x^2 + 3x + 2 = 6

2x^2 = 4

X = √2

brainliest pls took long enough to solve
