2x+3=4x+2

-2 both sides

2x+1=4x

-2x both sides

1=2x

2x=1

÷2 both sides

x=0.5 or 1/2

Help please !!!!!!!!!!!!!!
ohaa [14]
To start, we're given the range that x lies in: from -1 to 4. We know from the fact that -1 \leq x that -1 will be <em /><em>included</em> in that range, so we mark -1 on the number line with a solid circle. We also know from x\ \textless \ 4 that, while x can be any value <em>up to</em> 4, it does not <em>include </em>4. We indicate this by drawing a hollow circle around 4 on the number line. Since x can be <em>any value within this range</em>, we make that fact clear by drawing a bold line between the points -1 and 4 on the number line. I've attached an image of what our final graph would look like.

Please help! <br> Simplify. Your answer should contain only positive exponents.
maxonik [38]

Answer:

\frac{1}{4k^3}

Step-by-step explanation:

It's already in a form that only ha positive exponents.  Just to state it though you could rewrite it as k*(4k^{4})^{-1} or k*4^{-1}*k^{-4}  The question asks for positive exponents though so yu don't need to do that.

You also need to know \frac{x^a}{x^b}=x^{a-b} so in this case \frac{k}{k^4}=\frac{k^1}{k^4} =k^{1-4}=k^{-3}=\frac{1}{k^3}

so \frac{k}{4k^4}=\frac{1}{4}*\frac{k}{k^4}=\frac{1}{4}*\frac{1}{k^3}=\frac{1}{4k^3}

-m
dimaraw [331]

-m - (7/8) = -10

m = 10 - (7/8)

LCM = 8

m = (80 - 7)/8

m = 72/8

m = 9

hope it helps...!!!
