Answer:

(a)\ m+ 2.1 > n + 2.1

(b).\ m - (-4) > n - (-4)

(c)\ 9 +m> 6 + n

Step-by-step explanation:

Given

m > n

Required

Select true inequalities

(a)\ m+ 2.1 > n + 2.1

Subtract 2.1 from both sides

m > n

This is true

(b).\ m - (-4) > n - (-4)

Open brackets

m + 4 > n + 4

Subtract 4 from both sides

m > n

(c)\ 9 +m> 6 + n

m> -9+6 + n

m> n-3

This is also true

What is the y-intercept of the equation 2g(x)+2x=4
uysha [10]

2g(x) +2x=4

2( g(x) +x) = 2(2)

g(x) + x= 2

g(x) = 2- x

To get y intercept,

put x=0

g(x) = 2- 0

g(x) = 2

So,y intercept = 2

How to tell if an equation is linear or nonlinear?
gogolik [260]
A linear equation will contain  a term in x  has the highest degree.  For example  y = 2x - 5 . A non linear will contain terms with exponents 2 or higher 
eg x^2 - 2x - 5  is nonlinear.

Solve the following quadratic by<br> completing the square.<br> y = x2 - 6x + 7
kobusy [5.1K]

Answer:

x = 5  or   x = 1

Step-by-step explanation:

 x² - 6x + 7 = 0

x² - 6x = -7

x² - 6x + 9 = -7 + 9      1/2 of the x term than square it and add it the both sides.

(x - 3)(x - 3) = 2

( x -3)² = 2

\sqrt{(x - 3)^2 = \sqrt{2}

(x -  3) = ± 2

x - 3 = 2  or  x - 3 = -2

x = 5     or  x = 1
