What is the solution to this system of linear equations? 7x – 2y = –6 8x y = 3 (–6, 3) (0, 3) (1, –5) (15, –1)
erik [133]

Answer:

(0,3)

Step-by-step explanation:

we have

7x-2y=-6 ----> equation A

8x+y=3 ----> equation B

Multiply the equation B by 2 both sides

2(8x+y)=2*3

16x+2y=6 ------> equation C

Adds equation A and equation C

7x-2y=-6\\16x+2y=6\\--------\\7x+16x=-6+6\\23x=0\\x=0

Find the value of y

7(0)-2y=-6

-2y=-6

y=3

the solution is the point (0,3)

Does anyone know how to solve the equation ln 2 - ln(x - 8) = 4, giving nearly 80 points
RoseWind [281]

Answer:

x= 8.1353

x= 8.135 (rounded to the nearest tenth-thousandths)

x= 8.14 (rounded to the nearest thousandths)

x= 8.1 (rounded to the nearest tenth)

Step-by-step explanation:

<u><em>Note I am not 100% sure with my answer</em></u>

2 − ln (x − 8)= 4

−ln (x − 8) + 2= 4

−ln (x − 8) + 2 + −2= 4 + −2

−ln (x − 8)= 2

−ln (x − 8)/−1= 2/−1

ln (x − 8)= −2

<solve for the logarithm (ln)>

ln (x − 8)= −2

e^ln (x − 8)= e^−2

x − 8= e^−2

x − 8= 0.1353

x − 8 + 8= 0.1353 + 8

x= 8.1353
