Answer:
r = -4
Step-by-step explanation:
2r + 7 = - 1
2r = - 1 - 7
2r = - 8
Answer:
.1 approx.
Step-by-step explanation:
5/60 and x/100%
Cross multiplying...
5 x 100% = 5
5/60 ~= .1
( I dunno if I am right, so please check first.)
so confusing i really need help with this math
Answer:
(-1,6)
Step-by-step explanation:
Given that(4,6) is on the graph of f(x)
f(-4x) means x is multiplied by -4
When x is multiplied by -1 then there will be reflection over y axis
We multiply every point by -1. so multiply the x values of the given point (4,6) by -1
New point is (-4,6)
If any number is multiplied with x then there will be a horizontal compression or stretch.
4 is multiplied with x , so there will be horizontal compression because 4 is greater than 1
To get new point, we divide the x values by 4 for compression
we already got (-4,6) after multiplying by -1
Now we divide the x coordinate -4 by 4 = -1
So corresponding point for the function f(-4x) is (-1,6)
(2x-3)(x+4) —> x= 3/2 x= -4
