8/10 are equal to 4/5 because 4×2=8 and 5×2=10 so 8/10
Answer:
JH = 97.9
Step-by-step explanation:
25/12 = x/47
12x = 1175
x = 97.917
Answer:
x=5
Step-by-step explanation:
-3x+7=-8
Bring 7 to the other side, it becomes negative
-3x=-8-7
Signs are same on rhs so u add
-3x = -8+-7= -15
Bring -3 to the other side n divide
therefore,
x=-15/-3
= +5 (two negatives become positive)
Hope it helps!
Answer:
x=15
Step-by-step explanation:
You need to do proportions.
Since 16/12 = 1.3333333333333333333,
than you need to divide 20 by 1.323333333, so 20/1.3333333333333= 15
Answer:
(-infinity, 4]
Step-by-step explanation:
The range is the possible y values
The smallest that (x+3)^2 can be is zero
f(x) = 4 − 2(x + 3)^2
f(x) = 4 -2(0) = 4
This is the maximum value
As the square term gets bigger we are subtracting a larger amount and it will get more negative
Let x = infinity, x+3 = infinity and infinity ^2 = infinity and 2* infinity = infinity
f(x) = 4 - infinity
= -infinity
The range is -infinity to 4
