Y = 2x + 9 + xis this equation linear or nonlinear?

2 answers:

5 0

$\text{This would be a linear line}\\\\\text{Due to the fact that when you solve the equation, you should get y = 3x + 9}\\\\\text{The slope in constant. The slope here would be 3}\\\\\text{Since the line is always at a constant rate of change, this would make}\\\text{the line linear}$

Answer:

Linear

Step-by-step explanation:

Add 2 x and x . y = 3 x + 9 A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 1 .

Factorise: a squared +8a -20

Vaselesa [24]

Factor out the 4 in both equations
8a^2-20^2=(2^2 times a^2 times 2)-(2^2 times 5)
therefor it is also equal to
(2a)^2 times 2-(2^2 times 5)
we can force it into a difference of 2 perfect squares which is a^2-b^2=(a-b)(a+b)
(2a√2)^2-(2√5)^2=((2a√2)-(2√5))((2a√2)+(2√5))

What is the 7th term of the geometric sequence where a1 = 625 and a2 = −125?

myrzilka [38]

Common ratio, r = (-125)/625 = -0.2
First term, a = 625

7 term
= ar^6
= 625(-0.2)^6
= -0.04

Which statement is true?

Nadusha1986 [10]

The correct statement is D.

Step-by-step explanation:

Given,

For backyard

Length = 5x-2

Width = 2x+4

For house

Length = 5x-2

Width = 4x-12

For driveway

Length = x+10

Width = 4x-12

To find the correct statement.

Formula

The area of a rectangle = Length × Width

So,

The area of the house and the driveway = (5x-2)(4x-12) + (x+10)(4x-12)

= (4x-12)(5x-2+x+10)

= (4x-12)(6x+8)

= $24x^{2} +32x-72x-96$

= $24x^{2} -40x-96$

So, the correct statement is D
