Answer:
4
Step-by-step explanation:
Given that:
Let the two numbers = a and b
H. C. F of the two numbers = 2
L.C.M of the two numbers = 54
If a = 27 ; b =?
The product of a and b = product of their L. C. M and H. C. F ;
HENCE ;
27 * b = 2 * 54
27b = 108
b = 108/27
b = 4
Hence, second number is 4
Answer:
A) -2 - i√3 , -2 + i√3
Step-by-step explanation:
Solve using quadratic formula
x² + 4x + 7 = 0
The Almighty Formula
= -b ± √b² - 4ac/2a
Where ax + bx² + c = 0
From the above question
a = 1, b = 4, c= 7
Hence,
-4 ± √4² - 4 × 1 × 7/2 × 1
-4 ± √16 - 28/2
=( -4 ± √-12)/2
Since
b² - 4ac < 0
We have two complex roots
Simplifying
( -4 ± √-12)/2
= -4/2 ± √-12/2
= -2 ± 2√3i/2
= -2 ± √3i
Therefore,
-2 - √3i , -2 + √3i
or
-2 - i√3 , -2 + i√3
Option A , is the correct answer
Answer: if this is supposed to be in slope-intercept form
the equation would be: y = -2/5x + 7
Step-by-step explanation:
so the slope is: -2/5 and the point is (10,3) considering that x = 10 and y = 3
so we would plug this information into this equation: y = mx + b (slope-intercept form)
3 = -2/5(10) + b
3 = -4 + b
b = 7
and if we plug this in:
y = -2/5x + 7
Answer:
the second one, B
Step-by-step explanation:
This is because in both numbers the decimal was moved back one.
I added the two checks together, then subtracted $45. $375.42 + <span>$24.95 = $400.37 -$45.00= $355.37</span>
