1) Sketching it
Since the line segment AD = 10x -5 and AC= 3x +1 and CD= 15
According to the Segment Addition postulate we can write:
3x+1+15=10x-5 <em>Combining like terms</em>
3x +16 = 10x -5 <em>Subtract 16 from both sides</em>
3x = 10x-5-16 Subtract 10x from both sides
3x-10x =-21
-7x = -21
7x=21 <em>Dividing by 7 on both sides</em>
x=3
Answer:
-0.8 or -4/5
Step-by-step explanation:
You could do this a couple of ways. If you wanted to change your equation into slope-intercept form to make it easier for you, then you can do as follows:
4x + 5y = 10
5y = -4x + 10
y = -4/5x + 2
So your slope is -4/5.
Or you could do -A/B when your equation is in standard form. A is the term in front of the x value and B is the term in front of the y. Both strategies give you -4/5 for the slope.

if its wrong im sorry
Step-by-step explanation:
you don't know how exponents work ?
the exponent simply says how often the base value has to be multiplied by itself.
e.g. 5³ = 5×5×5 = 125
and when it says x=2, then you need to put 2 at every location, where is says "x".
so,
x⁵ for x = 2 means 2⁵ = 32
8² = 64
2⁴ = 16
