Answer:

2x^2 +11

Step-by-step explanation:

f(x) = 3x^2 + 2 and g(x) = x^2 – 9

(f – g)(x) =  3x^2 + 2 -( x^2 – 9)

Distribute the minus sign

                     3x^2 + 2 - x^2 + 9

Combine like terms

                     2x^2 +11

Tashia paid two months rent and a $500 security deposit when she signed her lease. In total, she paid $2,400.
fiasKO [112]

The equation that represents the scenario is  2x + 500 = 2400

The cost of one month rent is $950

She paid two months rent and a $500 security deposit when she signed for a lease. In total she paid $2400.

let

the cost of a month rent = x

Therefore,

<h3>Total cost Equation</h3>
  • 2x + 500 = 2400

The cost of the one month rent can be calculated as follows:

  • 2x + 500 = 2400
  • 2x = 2400 - 500
  • 2x = 1900
  • x = 1900 / 2
  • x = $950

Therefore, the equation that represent the scenario and cost of one month rent are as follows;

  • 2x + 500 = 2400
  • cost of one month rent = $950

Help me pleasee (10 points)
Montano1993 [528]

Answer:

B

Step-by-step explanation:

Givens

a^2 + b^2 = c^2

a = 4x

b = x + 2

c = 3x + 4

Solution

(4x)^2 + (x + 2)^2 = (3x + 4)^3                  Remove all the brackets.

16x^2 + x^2 + 4x + 4 = 9x^2 + 24x + 16  Collect like terms on the left

17x^2 + 4x + 4 = 9x^2 + 24x + 16            Subtract the terms on the right

8x^2 - 20x - 12 = 0

This factors into

(4x - 12)(2x + 1)

There are 2 answers

4x - 12 = 0

4x = 12

x = 12/4

x = 3

or

2x + 1 = 0

2x = - 1

x = - 1/2

You have to look at x = -1/2 carefully. The problem is that 4x = 4*(-1/2) = - 2 which is not possible in Euclidean Geometry.

So the only answer is x = 3

In a bolt factory, machines 1,2, and 3 respectively produce 20%, 30% and 50% of the total output. of their respective outputs 5%
lorasvet [3.4K]

Answer:

a. 1/10 or 10%

b. 1/2 or 50%

Step-by-step explanation:

Since the combination of machines 1, 2 and 3 produce 100% of the total output when added together, then the probability of choosing a bolt at random that is defective is: 5 + 2 + 3 = 10% out of 100% or 10/100, which is 1/10 or 10%.

If the bolt that is choosen at random is defective, than the probability that it came from machine 1 is 5/10 or 1/2 which is also 50%.
