Answer:

b = 7

Step-by-step explanation:

You can start with either inequality, then add the required amount to make it look like the other one.

___

Starting with x > -21

x > -21

x + 7 > -14 . . . . . add 7 to both sides

b = 7 . . . . . . . . . compare to the form x + b > -14

___

Starting with x + b > -14

x + b > -14

x + b -7 > -21 . . . add -7 to both sides

b -7 = 0 . . . . . . compare to the form x > -21. 0 is added to x.

b = 7 . . . . . . . . add 7 to both sides

Explain what you can tell just by comparing the symbols in the picture graph

olchik [2.2K]

Picture graphs usually show amounts using...pictures! So if you looked at the symbols, you can likely guess the amounts. It might show how many students preferred hamburgers by using a hamburger to represent every 5 students. Just by quickly glancing at a picture graph, you can usually tell which result is the greatest.

Rewrite! Write an new and equivalent equation that is easier to solve

Marysya12 [62]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - an equation in a standard form

To do - simplify the equation so as to obtain an easier one

Since the equation provided isn't in it's general form , let's first convert it ~

General form of a Linear equation -

$\bold{ax + b = 0}$

The equation after getting converted will be as follows ~

$- 7 + ( \frac{4x + 2}{2} ) = 8 \\ \\ \implies \: \frac{ - 14 + 4x + 2}{2} = 8 \\ \\ \implies \: - 14 + 4x + 2 = 16 \\ \\ \implies \: 4x = 16 + 14 - 2 \\ \\ \implies \: 4x = 28 \\ \\\bold{ General \: form \: \dashrightarrow \: 4x - 28 = 0}$
