Jupiter diameter is 29.330664 bigger the mercury diameter so that means the answer is not on there but is near B, so the answer is B
Short Answer B
Argument
A
A will give you x = +/- 5i
x^2 + 25 = 0
x^2 = - 25 Take the square root.
sqrt(x^2) = +/- sqrt(-25)
x = +/- (5)i which is a complex number.
B
Is the answer
x^2 = 25
sqrt(x)^2 = sqrt(25)
x = +/- 5
C
Can't be factored just by looking at it. You can show that C is not true just by putting 5 into the equation
f(x) = x^2 + 10x - 25
f(5) = 25 + 10*5 - 25
f(5) = 50
C is not true.
D
D can be eliminated as C was
f(x) = x^2 - 5x - 25
f(5) = -25 ( l'll let you show this is not true). 5 is not a solution because it does not make f(x) = 0
Answer:
y = 7x - 12
Step-by-step explanation:
Parallel lines have same slope.
y = mx + b
m - > slope & b -> y-intercept
y = 7x
So, slope = 7 & (2 , 2)
y - y1 = m(x -x1)
y - 2 = 7(x - 2)
y - 2 = 7x - 14
y = 7x - 14 + 2
y = 7x - 12
The slope is -3
work:
m= y2-y1 / x2-x1
m= 4-13 / 1 - (-2)
m= -9 / 3
m= -3
