Answer:
The answer is y = 80±
and x = ±
Step-by-step explanation:
We need to solve this system of equations algebraically
y + x = 19 - 
..............................................(1)
x+y = 80 ...............................................................................(2)
Substituting equation (2) in equation (1)
80 = 19 -
-61 =
x = ±
Where i is the imaginary
Then the value of y = 80±
This is the solution to this system of equations
Answer:
42.2
Step-by-step explanation:
all you have to do is add up the number just how they are
y + 3 = 
(x - 5)
the equation of a line in point- slope form is
y - b = m ( x - a )
where m is the slope and (a, b) a point on the line
here m = and (a,b) = (5 , - 3 )
y + 3 = (x - 5 ) ← in point-slope form
Answer:
slope is (-7/4) and y-intercept is 7
Step-by-step explanation:
If we convert the equation 7x + 4y = 28 into Slope-intercept form, we can find the slope and the y-intercept.
7x + 4y - 7x = 28 - 7x
4y = 28 - 7x
divide both sides by 4
y = (28 - 7x)/4
y = 7 - 7x/4
slope is (-7/4) and y-intercept is 7
