Answer:

y=3*x

Step-by-step explanation:

john bought 3 notebooks for 9 dollars

so 9/3=3

notebooks costed 3 dollars each

x-number of notebooks

y-cost of notebooks

y=3*x

because 3 dollar cost every notebook you could buy.

if i buy 2 notebooks

so x=2

y=3*2=6 dollars

if I buy 3 notebooks

then y=3*3=9 dollars

end this way continues

The equation is y=3x because you have to divide 9 by 3 (since they bought 3 notebooks for $9 & you’re trying to find how much for 1 notebook)

Given Sn=2n^2 - 5n, find
brilliants [131]

Answer:

a) -3

b) 117

c) 100

Step-by-step explanation:

(a) 2(1)²-5(1)

1²= 1

2×1= 2

2-5= -3

(b) 2(9)²-5(9)

9²= 81

81×2= 162

162-45= 117

(c) 2(4)²-5(4) +2(8)²-5(4)

4²=16

16×2= 32

32-20= 12

8²=64

64×2= 128

128-40= 88

88+12= 100

hope it helps!

Find the value of x when m<2 = x + 64​
polet [3.4K]

Answer:

-9

Step-by-step explanation:

The triangle has two sides that are the same, so it is an isosceles triangle.  Therefore, the base angles are the same.

Angles of a triangle add up to 180°, so:

70 + (x + 64) + (x + 64) = 180

70 + 2x + 128 = 180

2x = -18

x = -9
