Answer:
J Monica is right
Step-by-step explanation:
Add three to both sides, divide by 4 you get x
4
<em>Let the number is n</em>
<em>it means that n÷2 = -12</em>
<em>multiplying both sides by 2, we get</em>
<em>n = -24 solution.</em>
Answer:
Solution given:
y=6/7x+7
Comparing above equation with y=mx+c
we get
m=6/7
a What is the slope of a line parallel to it?
Since for parallel slope are equal ,
slope will be 6/7.
b What is the slope of a line perpendicular to it?
Since for perpendicular line slope is reciprocal to another line but negative so
slope of line is-7/6.
Since the solution cannot be negative hence the true solution to the expression is x = 10
<h3>Laws of logarithm</h3>
Given the logarithmic expression
ln 20 + ln 5 = 2lnx
In logarithmic law, the sum of log is equivalent to its product .The equation above can be written as:
ln(20*5) = 2lnx
ln100 =2lnx
ln100 = lnx^2
x^2 =100
x = 10
Since the solution cannot be negative hence the true solution to the expression is x = 10
