Answer:
y = 1/2x +6
Step-by-step explanation:
We have a point and a slope. Therefore we can use the point slope form to create a line
y-y1 = m(x-x1)
y-5 = 1/2(x--2)
y-5 = 1/2(x+2)
Distribute the 1/2
y-5 = 1/2x +1
Add 5 to each side
y-5+5 = 1/2x +1+5
y = 1/2x +6
This is in slope intercept form
W=A\L
Divide L from both sides
The L in the right cancels out
we have
Let's Isolate the variable y in each of the cases and then compare with Fiona's equation to determine the solution of the problem
case A) 
Multiply by 
both sides
Divide by 
both sides
therefore
the case A) is not equal to Fiona's equation
case B) 
Multiply by both sides
Divide by 
both sides
therefore
the case B) is not equal to Fiona's equation
case C) 
Multiply by both sides
Divide by both sides
therefore
the case C) is not equal to Fiona's equation
case D) 
Multiply by 
both sides
Divide by both sides
therefore
the case D) is equal to Fiona's equation
<u>the answer is</u>
Answer:
X= 5, -9
Step-by-step explanation:
(X+2)² =49
Expand the bracket,
(X+2) (X+2)= 49
Apply the distributive property;
X(X+2) +2 (X+2) =49
X²+2X+2X+4=49
X²+4X+4=49
Move 49 to the left side of the equation;
X²+4X+4-49=0
X²+4X-45=0
Apply Factorisation method;
Consider the form
a²+bx+c=0
Find two numbers whose sum is equal to b and whose product is equal to c.
Comparing with our equation;
B =4 and C =45
We can use 9 and -5, this is because ;
9+(-5)=4 and 9*(-5)= 45.
Replace X +4X-45=0 with (X-5) (X+9)=0
Therefore;
X-5=0
X+9=0
Moving to the left side of the equation;
Therefore X= 5 and -9
50% is greater than 33 1/3% so overall it would be greater than the original
