Answer:
Step-by-step explanation:
-x+4y=16
-x=16-4y
x=(16/-1)-(4y/-1)
x=-16+4y
Answer:
C and A
Step-by-step explanation:
expand the things in parentheses so for C
1/2(x + 16) = 1/2(x) + 1/2(16) = 1/2 x + 8
same process for A
The word is CALCULATE. ( to determine or ascertain by mathematical methods; compute
Answer:
x=0
x=-1
x=-5
Step-by-step explanation:
To find the roots, we set the equation equal to zero and factor.
x(x²+6x+5)=0 [factor]
x(x+1)(x+5)=0 [set each factor equal to 0]
x=0
x+1=0 [subtract both sides by 1]
x=-1
x+5=0 [subtract both sides by 5]
x=-5
Now, we have found three roots, x=0, x=-1, x=-5.
