The sum of 4 times a number and -3 added to 9 times the number
Phoenix [80]

Answer:

The sum of 4 times a number and -3 added to 9 times the number is:

4x + (-3 + 9x)

Step-by-step explanation:

Determine what each of the words means

"the sum of" - you are going to be adding the following two numbers.

"4 times a number" - Let x be the number, so, 4x is the first number.

"and -3 added to" - again, it's going to be addition of this number and the following number.

"9 times the number" - let x be the number, so, 9x is the second number in the second addition.

Now that we know what it all means, put it together:

4x + (-3 + 9x)


I really hope this helps you =)

What is the slope of the line through (3,2) and (-3,4)?
NISA [10]

Answer:

slope = - \frac{1}{3}

Step-by-step explanation:

calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (3, 2 ) and (x₂, y₂ ) = (- 3, 4 )

m = \frac{4-2}{-3-3} = \frac{2}{-6} = - \frac{1}{3}
