Slope = 4/5 because the formula for slope is rise/run. count the x and y units point one and point two are away from each other.
1.5 because 5 goes into 7 one time then u subtract 7 - 5 wich is 2 so u bring that down then the 5 from 7.5 goes down wich forms 25 and 25 ÷ 5 = 5 so the final results r 1.5 :) :) :) :)
Answer:
r = t/t-1
Step-by-step explanation:
Here, we want to make r the subject of the formula
what this mean is that we want to write the equation in terms of r
we have this as;
t = r/r-1
t(r-1) = r
tr - t = r
tr-r = t
r(t-1) = t
r = t/(t-1)
The coordinates of the vertex are (h,k) so we can write:-
f(x) = a(x -2)^2 - 4
now when f(x) = -7 x = 1 so:-
-7 = a(1-2)^2 - 4
-7 = a - 4
a = -3
so the vertex formula is
f(x) = -3(x - 2)^2 - 4
standard form:-
f(x) = -3(x^2 - 4x + 4) - 4
= -3x^2 + 12x - 16
No the first one worked not the second one
