Answer:
x =±2 sqrt(6)
Step-by-step explanation:
x^2 = 24
Take the square root of each side
sqrt(x^2) = sqrt(24)
x = ±sqrt(4*6)
x =±sqrt(4) sqrt(6)
x =±2 sqrt(6)
Answer:

Step-by-step explanation:
Given
Point: (-7,2)
x + 3y = -5
Required
Find B- - A in Ax + By = 3
To start with; we need to calculate the slope of x + 3y = -5

Subtract x from both sides


Divide both sides by 3


The slope of the line is the coefficient of x
Slope = 
The question says line Ax + By = 3 is parallel to line x + 3y = -5; This means that they have the same slope of 
Having calculated the slope, next is to calculate the equation of the line using the following formula;

Where m is the slope; m =
; 
Substitute these values in the formula above; the formula becomes


Cross Multiply

Open brackets

Add x to both sides


Add 6 to both sides


Multipby both sides by -3




Comparing the above to Ax + By = 3





Answer:
The first choice is correct
Step-by-step explanation:
$32.00 x 15% = 4.80. 32.00-4.80=27.20. Another way to work it is the first choice, subtracting 15% from 100% and then multiplying 85% by $32.00. Same answer
Hello :
by : <span>an = an-1 + 9.
n= 2 : a2 =a1+9
a2 = -12+9 = -3
n=3 : a3 = a2 +9
a3 = -3+9 = 6
n = 4 : a4 = a3 +9
a4 =6+9 = 15</span>
