<span>y = -1/2x +2 1/2</span>
General equation;
y = mx + c
Calculating the slope;
Change in y/ (change in x) = gradient m
(2-1)/(1-3) = - 1/2
Replacing m gives;
y= -1/2x + c
Calculating the value of c
take point (1,2) above and replace y with 2 and x with 1
2=-1/2 *1 +c
c = 2 1/2
Equation then is
y = -1/2x +2 1/2
Answer:
4x-11=5
Step-by-step explanation:
If u were to divide each side of the equation by 2, the 2 on the left which is supposed to distribute into the parenthesis would disappear, and the 10 on the right side would turn into 5.
What is left is this,
4x-11=5
Looks like a pretty regular system, no parallel lines. In fact the second equation is a vertical line as written; not sure if that's a typo. Either way,
Answer: EXACTLY ONE SOLUTION
Answer:
m-a = n
Step-by-step explanation:
a=m-n
Subtract m from each side
a-m = m-n-m
a-m = -n
Multiply each side by -1
-a+m = n
m-a = n
Answer:

Step-by-step explanation:

Set up equation
Step 1: Simplify

Step 2:Multiply by conjugate

Step 3:Simplify

We can reduce this and we must make the imaginary number and real number serpate equations.

Reduce each by 2
