Absolute value only removes the negative signs. Just multiply the numerator and the denominator
Answer:let me know please
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Equation of line 1:
Choose two points : (-1, 0) & (0,2)
y -intercept = b = 2
y = mx+ 2
Plugin the values of the points ( -1 , 0) in the above equation
0 = -1m + 2
-2 = -m
m = 2
Equation of line 1 : y = 2x + 2
Equation of line 2:
(5,0) & (0,5)
y-intercept = b = 5
y = mx +b
y = mx + 5
Plugin the value of points (5 , 0) in the above equation
0 = 5m + 5
-5 = 5m
-5/5 = m
m = -1
Equation of line 2: y = -x + 5
Conclusion: 2x + 2 = -x + 5
I think... 1500
Step-by-step explanation:
multiply 30 and 25 then times 750 as your answer by 2 to get 1500
Just replace x^2+4 with a
factor out on left side
(x^2+4)^2+32=12(x^2+4)
replace x^2+4 with a
a^2+32=12a
minus 12a both sides
a^2-12a+32=0
solve
factor
what 2 numbers mulitply to get 32 and add to get -12
-4 and -8
(a-4)(a-8)=0
set each to zero
a-4=0
a=4
a-8=0
a=8
remember
a=x^2+4
so
4=x^2+4
0=x^2
0=x
8=x^2+4
4=x^2
+/-2=x
x=-2, 0, 2
