Answer:
8%
Step-by-step explanation:
We will use the equation provided to solve this problem.
Lets plug in the values:
First, divide both sides by 800.
Multiply x by 1
Now, we multiply .08 by 100 to get our interest rate:
(.08)100 = 8
The interest rate is 8%
To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
First we have parentheses.
-4(3 - 1) + 2
3 - 1 = 2
-4(2) + 2
We have no exponents so go on to multiplication
-4(2) + 2
-4 * 2 = -8
-8 + 2
No division so go to addition
-8 + 2
When adding a positive number with a negative number you will act as if you are subtracting the two numbers, then take the sign of the largest number (disregarding the signs). In this case the largest number is 8 and its sign is negative. Your answer will have a negative sign.

Step-by-step explanation:
Find the gradient of AB
-2.5
Find the gradient of perpendicular
0.4
Make the equation
y= 0.4x + c
Apply point A
3= 0.4*2+c
3-0.8= c
c= 2.2
y= 0.8x + 2.2
6w-y=2z
6w=2z+y
w=(2z+y):6
w=(z:3)+(y:6)
