Answer:
Step-by-step explanation:
5x+9y=-3 Multiply both sides by 8
40x+72y=-24
-53x-8y=-3 Multiply both sides by 9
-477x -72y= -27
sum the equations vertically to eliminate one variable
40x+72y= -24
-477x-72y= -27 (the y cancels out )
-477x =-51 (-24 + -27=-51)
-477x=-51 / -477 divide both sides by -477
x =51/437
5x 51/437=9y= -3 substitute the value of x
y= -174 /437
(x,y) = (51/437, -174/437)
Answer:
Step-by-step explanation:
Area A = 1/2 bh
36a^2b^4 = 1/2 × (12ab)h
Cross multiply
72a^2b^4 = 12abh
Dividing by 12ab
h = (72a^2b^4)/12ab
h = 6ab^3
Answer:
D
Step-by-step explanation:
P(3) = ⅙
P(5) = ⅙
Trials are independent so,
P(3 then 5) = 1/6 × 1/6 = 1/36
Point-slope for a line is:
(y-y1)=m(x-x1) where (x1,y1)=(1,1) and m=6 so
y-1=6(x-1)
