Answer:
35
Step-by-step explanation:
Since all the angles are the same in this triangle, all the sides should be the same too.
Hence, 3x - 5 = 4x - 30
5 + -1x = -30
-1x = -35
x = 35
Hope this helped!
The correct answer is actually (a) because rate of change is x/y (or that's how I learned it) then the more big the slope the bigger the rate of change
Answer:
a)13x+3
b) -3x-13
c)4x^2-24
d)-3x^2 +3x
Step-by-step explanation:
a) combine like terms
5x-3+8x+6 so combine the -3 and +6 and 5x and 8x
So 13x+3
b)There is an invisible one in front of (2x-5) and an invisible -1 in front of (5x+8). Distribute these.
2x -5 - 5x -8
So -3x-13
c) Distribute the four to everything in the brackets.
4(x^2-6) becomes 4x^2-24
d) Distribute:
-3x (x-1) becomes -3x^2 +3x
Hey dear !!
equation of point slope is of form :-..
◆y-y1 =m(x-x1). ----------(*1)
so here m = 2
y1= 9 , x1 =5
put these value in eqn 1
=) y-9 =2(x-5)
option 1 st is correct
