Answer:6

Step-by-step explanation:

4.8(x)+1.2(y)=2.4

y would equal -6.

4.8(2)+1.2(y)=2.4

9.6 + 1.2y = 2.4 subtract 9.6 from both sides

1.2y = - 7.2 divide by 1.2 on both sides

y = -6

In 2010, the estimated population of Los Angeles was 3.79 × 106 people. The population of California that same year was about 9.

Olegator [25]

Answer:

The approximate population of the state of California in 2010 was $37,293,600\ people$

Step-by-step explanation:

Let

x----->the estimated population of Los Angeles in 2010

y----->the estimated population of the state of California in 2010

we know that

$y=9.84x$ ------> equation A

we have

$x=3.79*10^{6}\ people$

Substitute the value of x in the equation A and solve for y

$y=9.84(3.79*10^{6})=37.2936*10^{6}\ people$

$37.2936*10^{6}=37,293,600\ people$

I need help on a math assignment.

Answer:

(18 , - 10)

Step-by-step explanation:

5x + 4y = 50 .... (1)

x + 2y = - 2 ... (2)

Solve (2) for "x"

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

(3) ----> (1)

5(- 2y - 2) + 4y = 50 ⇔ - 6y - 10 = 50 ⇒ y = - 10 .... (4) 

(4) ----> (2)

x + 2(- 10) = - 2 ⇒ x = 18

(18, - 10)
