Answer:
y = 2500x -4989000
Step-by-step explanation:
To find the slope we use the formula
m = (y2-y1)/(x2-x1)
= (31000-26000)/(2008-2006)
=5000/2
2500
The slope is 2500
Then we use point slope form to write an equation
y-y1 = m(x-x1)
y-26000 =2500(x-2006)
Distribute
y-26000 = 2500x -5015000
Add 26000 to each side
y-26000+26000 = 2500x -5015000+26000
y = 2500x -4989000
Answer:
(- 1, - 3 )
Step-by-step explanation:
Given the 2 equations
2x + y = - 5 → (1)
2x - 5y = 13 → (2)
Subtracting (1) from (2) term by term will eliminate the x-0 term
0 - 5y - y = 13 - (- 5) , that is
- 6y = 18 ( divide both sides by - 6 )
y = - 3
Substitute y = - 3 into either of the 2 equations and solve for x
Substituting into (1)
2x - 3 = - 5 ( add 3 to both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1
solution is (- 1, - 3 )
Answer:
7.5
Step-by-step explanation:
draw the triangles separately then write a fraction for the small one x/6 and 10/8 then to get rid of the 6 to get x by itself you multiply by 6 to get X and for the other side you do 10/8 then multiply 1.25 times 6 to get 7.5
please add a thanks and a brainliest
hope this helped
Answer:
z is less than 3/4
Step-by-step explanation:
Answer:
X would have to equal 6. To work it out, you subtract 4 from each side to cancel out the 4. -x = -6. You have to make -x just x so you × each side by -1. You get x = 6.
