abruzzese [7]3 years ago

Answer:

(5,6)

Step-by-step explanation:

-6x+6y=6

-6x+3y=-12

solve the equation

-6x+6y=6

-6x=-12-3y

substitute the value of -6x into an equation

-12-3y+6y=6

minus -3y to 6y. and. add -12 to 6

-3y=-18

divide both sides by -3

y=6

substitute the value of 6 into an equation

-6x=-12-3•6

multiply -3 to 6

-6x=-12-18

minus -12 to -18 but since both are negative it's addition

-6x=-30

divide both sides by -6

x=5

the answer is (5,6)

What is ∑n=16[4(−5)n−1] equal to?<br><br> Enter your answer in the box.
Cerrena [4.2K]

Step-by-step explanation:

Geometric Sequence formula for general term:

an = a1(r^n-1)

a1 = 4 × (-5)^1-1

a1 = 4

r = -5

Summation formula for geometric sequence :

Sn = a1 ( 1 - r^n / 1 - r )

...<em>take n from the top of the summation.</em>

= 4 ( 1 -(-5)^6 / 1 -(-5)

= -10416.

Find x. Round to the nearest tenth if needed.
alexdok [17]

Answer:

x = 16

Step-by-step explanation:

Use that the addition of all internal angles of a triangle must add up to 180, and the fact that the two given triangles are similar:

51 + 65 + 4 x = 180

combine and solve for "x"

116 + 4 x = 180

4 x = 180 - 116

4 x = 64

x = 64 / 4

x = 16
