Midpoint of (x1,y1) and (x2,y2) is
((x1+x2)/2,(y1+y2)/2)
just average the x and y values
(5,-8) and (10,18)
((5+10)/2,(-8+18)/2)
(15/2,10/2)
(7.5,5)
the midpoint is (7.5,5)
Answer:
(2, - 4 )
Step-by-step explanation:
Given the 2 equations
10x + 7y = - 8 → (1)
7x + 7y = - 14 → (2)
Subtract (2) from (1) term by term to eliminate y
(10x - 7x) + (7y - 7y) = - 8 - (- 14) , that is
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
10(2) + 7y = - 8
20 + 7y = - 8 ( subtract 20 from both sides )
7y = - 28 ( divide both sides by 7 )
y = - 4
solution to the system of equations is (2, - 4 )
Answer:
Step-by-step explanation:
1.)
10p² - 7 = 243
10p² = 250
p² = 25
p = ±5 (meaning p can both equal -5,5)
2.)
9b²+9 = 684
9b² = 675
b² = 75
b = ±√75
= ± 5√3
The answer is 0.06 because 0.03 times 0,02 is 0.06 and check your spelling hope this helps .
Answer:
y = (-5/2)x + 1
Step-by-step explanation:
y = (-5/2)x + c
When x = 2, y = -4
-4 = (-5/2)(2) + c
-4 = -5 + c
c = -4 + 5 = 1
y = (-5/2)x + 1
