Answer:
x = -6
Step-by-step explanation:
I'm assuming you're solving for x
3/4 (4x + 8) = -12
you distribute the 3/4 to 4x and 8 so
3/4 times 4x = 3x
3/4 times 8 = 6
now looks like
3x + 6 = -12
3x = -12 - 6
3x = -18
x = -6
Answer:
It takes 27 minutes for the element to decay to 35 grams
Step-by-step explanation:
Given:
Initial amount = 790 grams
Final amount = 35 grams
Half life = 6 minutes
To find:
Time taken for the element to reduce into 35 grams = ?
Solutions
Time taken = 
On substituting the values given, Time taken
= 
= 
= 
= 26.97
= 27 minutes
You can go through the set and test each one out:
x=0:
2(0)+3 ≥ 7? Or 3≥7? No
x=0.6:
2(0.6)+3≥7? 4.2≥7? No.
x=2:
2(2)+3≥7? 7≥7? Yes.
x=4:
2(4)+3≥7? 11≥7? Yes.
x=6:
2(6)+3≥7? 15≥7? Yes.
The set is {2, 4, 6}.
Answer:
Slope is -7
Y intercept = -21
Step-by-step explanation:
The equation is Y=mx+b
M is the slope so -7 would equal the slope
B is where your Y- intercept already is so that would equal -21
