Answer:
Answer:Do it yourself.
Step-by-step explanation:
2p^2 + 3p - 4 - (-2p^2 - 3p + 4) =
2p^2 + 3p - 4 + 2p^2 + 3p - 4 =
4p^2 + 6p - 8 <==
Because for a fraction with a small denominator, you don't have to split them up into small pieces and as many pieces. For example: let's say you had 2/3. you draw a circle with 3 equal quadrants. Those quadrants are big because you didn't have to split the circle up into a lot of peices; only 3.
Now for a bigger denominator like 20/32, you have to split the circle into 32 peices. For all of them to fit, you have to make the pieces small.
Answer:
It's a function not a linear function
Step-by-step explanation:
Answer:
x = 2
Explanation:
First, make sure they both have common denominators ( 15 )
5 × 3 = 15 and 3 × 5 = 15
Whatever you do to the denominator you have to apply to the numerator. So, multiply the numerator and denominator of the first fraction by 3.
=
Next, multiply the numerator and denominator of the second fraction by 5.
=
Now we have:
Use distributive property on the numerators of both fractions.
Since the denominators are equal we can ignore them for now and find x.
9<em>x </em>- 3 = 5<em>x</em> + 5
We need to move like terms to different sides to isolate x. First, we can subtract 5<em>x</em> from both sides.
9<em>x</em> - 5<em>x</em> - 3 = 5<em>x</em> - 5<em>x</em> +5
4<em>x</em> - 3 = 5
Then, we can add 3 to both sides to cancel out the -3.
4<em>x</em> - 3 + 3 = 5 + 3
4<em>x</em> = 8
Finally, to find x we divide both sides by 4.
4x ÷ 4 = 8 ÷ 4
x = 2
