Answer:
186
Step-by-step explanation:
Divide 4 and 6.0 get 86 add 100 = 86 + 100 = 186
100% right. Kinda confusing ..
T=72, here's the work again :)
F(x) is another way of saying y
Y=2x-4
For the inverse you trade the x and y
X=2y-4
Then get y by itself
Add 4 to both sides
X+4=2y
Divide both sides by 2
X+4/2Z
An integer is a whole number. Two integers are opposite if they have the same distance away from zero. For example,
2 and -2
or
28 and -28
Those are all integers and opposites.
Hope this helps :)
Answer:
The answer to your question is:
Step-by-step explanation:
12.-
x² - 6x = 5
x² - 6x + (3)² = 5 + (3)²
x² - 6x + 9 = 5 + 9
(x - 3)² = 14
13.- x² - 6x = 12
x² - 6x + (3)² = 12 + (3)²
x² - 6x + 9 = 12 + 9
(x - 3)² = 21
x - 3 = ±√21
x1 = √21 + 3 x2 = -√21 + 3
x1 = 7.58 x2 = -1.58
14.- 2x² - 24x = - 20 Divide by 2
x² - 12 x = -10
x² - 12x + (6)² = - 10 + (6)²
x² - 12x + 36 = - 10 + 36
( x - 6) ² = 26
x - 6 = ±√26
x1 = √26 + 6 x2 = -√26 + 6
x1 = 11.1 x2 = 0.9
