10. 10x + 5y = 15 y=2x-3

Mathematics
1 answer:
Ivan2 years ago
6 0

Answer:

(i think) 1.5

Step-by-step explanation:

If you replace y with the equation y=2x-3, you get 5(2x - 3)

if you distribute this, it equals 10x - 15

combining like terms 10x + 10x - 15=15 will turn into 20x - 15 = 15

if you add 15 to both sides, -15 will cancel and 15 will turn into 30

20x = 30

divide both sides by 20 which will lead to x=1.5

What is the slope <br> y = (34/4)x + 3
statuscvo [17]

Answer:

The slope is 17 / 2.

Step-by-step explanation:

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y=mx+b

Find the values of m and b using the form y=mx+b.

m=17 / 2

b=3

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope: 17 / 2

y-intercept: 3

lys-0071 [83]

The numerical representation and final elevation of the fish relative to sea level are :

  • Final position = -13.52 + 7.8
  • Final position = - 5.72

<u>Given the Parameters</u> :

Initial depth of fish = - 13.52

Change in elevation of fish = 7.8 feets

Positions below sea level are represented as negative values (-) ;

Hence, initial position of fish = - 13.52

Change in position = Rise in depth of 7.8 feets

<u>The numerical representation of the final position of the </u><u>fish</u><u> </u><u>can</u><u> </u><u>be</u><u> written thus</u> :

  • Final position = Initial position + change in position

  • Final position = - 13.52 + 7.8

Hence, the final position of the fish will be :

  • Final position of fish = -13.52 + 7.8 = - 5.72
