Help, Due yesturday. ​

Mathematics

Answer:

Step-by-step explanation:

(0,3) and (6,0)

The line equation is y = mx + b

b is the y intercept. It is the y value from 0,3

So far, what you know of the line is that its equation is y = mx + 3

Now when y = 0, x = 6

So now we have

0 = m*6 + 3      So the slope (m) is the only unknown. Subtract 3

-3 = 6*m           Divide by 6

-3/6 = m

m = - 1/2

Answer: y = -1/2x + 3

Answer:

y = 1/2x + 3

Step-by-step explanation:

\frac{y_2-y_1}{x_2-x_1}=\\\\\frac{3-0}{0+6}=\\\\\frac{3}{6}=\\\\0.5

Slope is 0.5, y-intercept is 3, we get y = mx + b to y = 1/2x + 3.

Why does a logarithmic equation sometimes have an extraneous solution?
jonny [76]

The main reason behind this is using properties of logarithm .

like

when solving

  • log_2(x+2)+log_2(x-3)=3

There you use multiplication property and make addition to multiplication then you get extraneous solution because in plenty of cases they occur

like

  • (-2)²=(2)²

But

  • -2≠2

Same happens in case of logarithm

Five friends take a maths test
gulaghasi [49]

Answer:

Adam scored 60, Brandon scored 66, Chen scored 74, Damion scored 75, and Erica scored 75.

Step-by-step explanation:

Since five friends took the maths test, and Adam, Brandon, and Chen together together scored 200 marks; Brandon, Chen and Damion together scored 215; Chen, Damion and Erica together scored 224; and Damion and Erica scored more than Chen; While the five of them together scored 350 marks, to determine what are their individual scores the following calculations must be performed:

Adam + Brandon + Chen = 200

Damion + Erica = 150

Brandon + Chen + Damion = 215

Adam + Erica = 135

Chen + Damion + Erica = 224

Adam + Brandon = 126

Adam + Brandon = 126 + Chen = 200

Chen = 200 - 126

Chen = 74

Damion and Erica scored more than Chen

Chen + Damion + Erica = 224

74 + Damion + Erica = 224

Damion + Erica = 150

Damion = 75

Erica = 75

Brandon + Chen + Damion = 215

Brandon + 74 + 75 = 215

Brandon = 215 - 74 - 75

Brandon = 66

Adam = 350 - 75 - 75 - 74 - 66

Adam = 60

Therefore, Adam scored 60, Brandon scored 66, Chen scored 74, Damion scored 75, and Erica scored 75.
