y = 0 for the x-intercept, so
2х - 5*0 = 60
2x = 60
x = 60/2 = 30
(30, 0)

x = 0 for the y-intercept, so:
2*0 - 5x = 60
-5x = 60
5x = -60
x = -30/5 = -12
(0, -12)

Answer is a) (0, -12)(30, 0)

Savannah is planning to buy enough raffle

Alborosie

Answer:

20 tickets

Step-by-step explanation:

tickets/total tickets * 100% = 10% chance to win the raffle

x/200*100=10

solve for x

x/200 = 10/100

x = 200(0.1)

x = 20

IV. Intercepts. Give the intercepts of the following linear equations. 1) 5x + 3y = 8 2) 10x + 6y - 12 = 4 3) 2x – 3y = 5 4) 3x

rosijanka [135]

Answer:

1) $\frac{8}{3}$

2) $\frac{8}{3}$

3) $\frac{-5}{3}$

4)2

Step-by-step explanation:

1) 5x + 3y = 8

3y=8-5x

$y=\frac{-5}{8} x+\frac{8}{3}$

hence intercept is $\frac{8}{3}$

2) 10x + 6y - 12 = 4

10x + 6y = 16

6y=16-10x

$y=\frac{-10}{6} x+\frac{16}{6}$

hence intercept is $\frac{8}{3}$

3) 2x – 3y = 5

3y=2x-5

$y=\frac{2}{3} x+\frac{-5}{3}$

hence intercept is $\frac{-5}{3}$

4) 3x + 2y = 1

2y=-3x+4

$y=\frac{-3}{2} x+\frac{4}{2}$

hence intercept is 2

Which of these are correct relationships?

larisa86 [58]

I will assume here that we know the molar mass of sulfur, which is 32 g/mol (around).

this means that 0.5 moles will have half of it - the first option is correct!
8 moles will have 8 times this, which is 256 - the second option is not correct!
3 moles would have 96 grams -third option is not correct!
and we also know that 96 grams can't be 4 moles - so the forth option is not correct either
