Answer:
x = -20
Step-by-step explanation:
You move the 14 with the 6, since it is addition, it changes symbols ( from + to - ), so it'd be;
x = -6 - 14, since you are subtracting a negative number, you are technically adding them.
Answer:
An acute triangle
Step-by-step explanation:
All of the angles are less than 90 degrees
Plot the points ( -4,2.5), (-3,3), (-2,1.5), (-1,2), (0,1), (1,2), (2,3.5), (3,0.5), (4,2.5) then connect them with a line
Answer:
x < -3
Step-by-step explanation:
5x+10<-5
Subtract 10 from each side
5x+10-10<-5-10
5x < -15
Divide by 5
5x/5 < -15/5
x < -3
Answer:
Given:
x=log(3/5)
y=log(5/7)
z=log(sqrt(7/3)
Find x+y+z
Steps:
Using the law of logarithms, log A + log B = log (AB), we get
x+y+z
=log(3/5)+log(5/7)+log(sqrt(7/3)
=log(3/5*5/7*sqrt(7/3))
=log(3/7*sqrt(7/3)
=log((sqrt(3/7)*sqrt(3/7)*sqrt(7/3))
=log((sqrt(3/7)*sqrt(3/7*7/3))
=log(sqrt(3/7)*1)
=log(sqrt(3/7))
Now apply another law of logarithms, log(sqrt(A)) = (1/2) log(A)
=(1/2)log(3/7)
which is the final answer.
