Answer:

x = 9

y = 5

Step-by-step explanation:

3x + y = 32...(1)

3x - 2y = 17....(2)

multiplying equation (1) by 2 we get,

6x + 2y = 64...(3)

Adding eq(2) and (3) we get,

6x + 2y = 64

+ 3x - 2y = 17

----------------------

9x. = 81

therefore, x = 81/9

therefore, x = 9

substituting value of x in eq( 1)

3 * 9 + y = 32

27 + y = 32

y = 32 - 27

y = 5

Step-by-step explanation:

-(3x+y=32)

3x-2y=17

-3x-y=-32

3x-2y=17

-3y=-15

y=5

3x+(5)=32

-5. -5

3x=27

x=9

Answer:

x=9

y=5

What is the inverse of Y=-5x-7
Pepsi [2]

Answer:y = - 5x - 7

Step-by-step explanation:The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

here m = - 5 and b = - 7, hence

y = - 5x - 7 ← equation of line

Sauron [17]

Answer:

167/346 or 0.483

Step-by-step explanation:

From the question given above, the following data were obtained:

Number of Tails (T) = 167

Number of Heads (H) = 179

Probability of tail, P(T) =?

Next, we shall determine total outcome. This can be obtained as follow:

Number of Tails (T) = 167

Number of Heads (H) = 179

Total outcome (S) =?

S = T + H

S = 167 + 179

Total outcome (S) = 346

Finally, we shall determine the probability of tails. This can be obtained as follow:

Number of Tails (T) = 167

Total outcome (S) = 346

Probability of tail, P(T) =?

P(T) = T / S

P(T) = 167 / 346

P(T) = 0.483

Thus, the probability of tails is 167/346 or 0.483
