Answer:

(-3,2) is the solution to the system of equation

Step-by-step explanation:

Here, we want to know the point that serves as a solution to the system of equation

We equate the y

-2x + 4 = -1/3x-1

Multiply through by 3

-6x + 12 = -x-3

-6x + x = -3-12

5x = 15

x = 15/5

x = 3

Substitute x into one of the y

y = -2(3) + 4

y = -6 + 4 = -2

So the solution is;

(3,-2)

Answer:

False

Step-by-step explanation:

Given that a high school reports that its students' SAT scores were down by 12% in one year. The next year, however, the test scores rose by 20%.

Let score initially be 100

Down by 12

Next year score 88

For succeedingyear

increase is 20% = $20% of 88=17.6\\$

Score in the 2nd year = $88+17.6 = 105.6$

Hence overall scores improvement is 5.6% and not 8%
