Answer:

x=14/5

Step-by-step explanation:

Group like terms

2x+8x+7=35

Add similar elements: 2x+8x=10x

10x+7=35

Subtract 7 from both sides:

10x+7−7=35−7

Simplify

10x=28

Divide both sides by 10

10x/10 =28/10

Simplify:

x=14/5

Which number line represents the solutions to 1-2x1 = 4?

kaheart [24]

Answer:

Third option: $x = -2$ and $x = 2$

Step-by-step explanation:

Given:

$|-2x|=4$

For a modulus function, if $|f(x)|=a$ , then,

$f(x)=\pm a$

Here, $f(x)=-2x$ , $a=4$

∴ $-2x=\pm 4\\ -2x=-4\textrm{ or } -2x=4\\ x=\frac{-4}{-2}\textrm{ or }x=\frac{4}{-2}\\ x= 2\textrm{ or }x=-2$

Therefore, the third option is the correct answer as the graph has $x$ values as -2 and 2

Find the illegal values of c in the multiplication statement c^2-3c-10/c^2+5c-14-c^2-c-2/c^2-2c-15

matrenka [14]

c^2 + 5c - 14 = 0 
(c-2)(c+7) = 0 
c-2 = 0 or c+7 = 0 
c = 2 or c = -7 

c^2 - 2c - 15 = 0 
(c-5)(c+3) = 0 
c-5 = 0 or c+3 = 0 
c = 5 or c = -3
