Answer: 1st one
Step-by-step explanation:
the top part solve for x by simplifying both sides of the equation then isolating the variable.
x= -175
second part solve for x by simplifying both sides of the equation then isolating the variable ;
x = -175
third part:
x = -175
fourth part;solve for x by simplifying both sides of the equation then isolating the variable
x = -175
fifth part;
x= -175
sixth part;
nothing further can be done with this topic
so its
x= -175 :p
Answer:
b= -3
b=3/2=1.500
Step-by-step explanation:
step 1 . b • (2b + 3) - 9 = 0
Step-2 : Find two factors of -18 whose sum equals the coefficient of the middle term, which is 3 .
-18 + 1 = -17
-9 + 2 = -7
-6 + 3 = -3
-3 + 6 = 3
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -3 and 6
2b2 - 3b + 6b - 9
Step-4 : Add up the first 2 terms, pulling out like factors :
b • (2b-3)
Add up the last 2 terms, pulling out common factors :
3 • (2b-3)
Step-5 : Add up the four terms of step 4 :
(b+3) • (2b-3)
Two angles that are supplements add up to 180°.
"The angle" is five times its supplement.
If I call the supplement 'S', then 'the angle' = 5S .
S + 5S = 180°
Combine like terms: 6S = 180°
Divide each side by 6 : S = 30°
The supplement of 'the angle' = 30°.
That's one of the choices.
"The angle" = 5S = 150°.
That's NOT one of the choices.
|x-3|+5
With absolute value you're going to always use these | |
If you wish to go to right you will subtract x, if you wish to go to the left you will add to x.
And the +5 will do as it says and go up 5 or -5 go down by 5.
