help please! Darren is finding the equation in the form y = m x + b for a trend line that passes through the points (2, 18) and
andrezito [222]

Answer:  d) 14

Step-by-step explanation:

Equation of a line passing through (a,b) and (c,d):

(y-b)=\dfrac{d-b}{c-a}(x-a)

Equation of a line passing through (2, 18) and (–3, 8):

(y-18)=\dfrac{8-18}{-3-2}(x-2)\\\\\Rightarrow\ (y-18)=\dfrac{-10}{-5}(x-2)\\\\\Rightarrow\ (y-18)=2(x-2)\\\\\Rightarrow\ y-18=2x-4\\\\\Rightarrow\ y=2x-4+18\\\\\Rightarrow\ y=2x+14

Comparing resulting equation y=2x+14 to y = m x + b, we get value of b= 14.

Hence, correct option is d) 14

I need help in this question that is in the photo
mihalych1998 [28]
The answer is A, 1. In the statement x^2 >x, if we try 4, 5 and 8 for x, we get 16, 25 and 64 for x^2. The statement is true. But if we try x = 1, when we square it we still have 1. Therefore for x=1, x^2>x is false.

Simplify the expression (2x − 9)(x + 6)
kenny6666 [7]

<u>Answer:  </u>

Simplified form of given expression (2x – 9 )( x + 6 )  is 2 \mathrm{x}^{2}+3 \mathrm{x}-54

<u> Solution: </u>

We need to simplify following expression.

(2x – 9) ( x + 6)  

For sake of simplicity lets first assume 2x – 9 = A

So expression becomes A(x+6)

= Ax + A6

Now replace A by 2x – 9

= (2x – 9 ) x + (2x – 9 ) 6

=2 \mathrm{x}^{2}-9 \mathrm{x}+12 \mathrm{x}-54

On simplification, we get

=2 \mathrm{x}^{2}+3 \mathrm{x}-54

Hence simplified form of given expression (2x – 9 )( x + 6 )  is = 2 \mathrm{x}^{2}+3 \mathrm{x}-54
