Answer:

- 2 - 13

Step-by-step explanation:

( 4 x - 5 ) - ( 6 x + 8 )

= 4 x - 5 - 6 x + 8

Arranging like terms together

= 4 x - 6 x - 5 - 8

= - 2 x - 13

Can someone solve this so that i can confirm that I’m doing it right?
Svetach [21]

Answer:

Below in bold.

Step-by-step explanation:

x /18 = 12/10

10x = 18*12

10/w = 18/24

10/w =  3/4

3w = 40

w = 40/3 =  13 33   to the neaest hundredth.

Order the group of parabolas from widest to narrowest.
Mamont248 [21]

Answer:

\large\boxed{y=\dfrac{1}{4}x^2,\ y=-\dfrac{1}{2}x^2,\ y=\dfrac{3}{2}x^2}

Step-by-step explanation:

The equation of a parabola: y = ax²

The larger the value of |a|, the narrower the parabola.

We have the following coefficients a:

\left|\dfrac{1}{4}\right|=\dfrac{1}{4},\ \left|-\dfrac{1}{2}\right|=\dfrac{1}{2},\ \left|\dfrac{3}{2}\right|=\dfrac{3}{2},

We arrange the coefficients from the smallest to the largest:

\dfrac{1}{4}\

Therefore you have the answer:

y=\dfrac{1}{4}x^2,\ y=-\dfrac{1}{2}x^2,\ y=\dfrac{3}{2}x^2
