Solve the system of equations below. -3x + 6y = 9 5x + 7y = -49

Step-by-step explanation:

Given system of equations,

-3x + 6y = 9  ------(1)

5x + 7y = -49 ------(2),

LCM (3, 5) = 15,

5 × equation (1) + 3 × equation (2),

We get,

30y + 21y = 45 - 147

51y = -102

From equation (1),

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1
