Answer:
x=-1 and x=5
Step-by-step explanation:
we have
Solve it by completing the square method
We take the coefficient of x that is -4, divide it by 2 and then square it
so
square it
Adds 4 both sides
Combine like terms right side
Rewrite as perfect squares
take square root both sides
therefore
im not sure if it is right but i got 920 cm2. is that one of ur answers?
Ok so if I understand this correctly then you have to find out what each one of them are then add them to get the total number of both of them. So this is the equation I did. The one circled on blue is the formula I made for the equation and then the green one is the answer. which is 5 4/9
I hope this helps.
Answer: See explanation
Step-by-step explanation:
Point slope form: y - y₁ = m (x - x₁)
y₁ = 6
x₁ = -7
y - 6 = -1 (x - [-7])
y - 6 = -1 (x + 7)
y - 6 = -1x - 7
Add 6 to both sides
y = -1x - 1 <em>or </em>y = -x -1
Slope intercept form: y = mx + b
m = -1
b = 6
y = -1x + 6 <em>or </em>y = -x + 6
Standard form: Ax + By = C
Change slope intercept form into _x + _y = c
Slope intercept form: y = -x + 6
Standard form:
y = -x + 6
Add x to both sides
x + y = 6 <em>or </em>-x - y = -6
Hope I helped!
