Substitution would be a great approach to solving this system, because the first equation defines y as x - 10 and you can thus substitute x - 10 for y in the second equation:

2x + (x - 10) = 4

Then 3x - 10 = 4, and 3x = 14. Solving for x: x = 14/3.

Since y = x-10, subst. 14/3 for x to find y: y = 14/3 - 30/3 = -16/3

The solution is (14/3, -16/3).

Answer:

29,035.43 meters

Step-by-step explanation:

What we know:

- The elevation of the shore of the Dead Sea is -1,344.99 meters.

- The summit of Mt. Everest is 30,380.42 meters above the Dead Sea.

So, we just add the two values.

30,380.42 + (-1,344.99)

We can rewrite this as 30,380.42 - 1,344.99 since adding a negative is the same as subtracting that number.

And we get 29,035.43 meters as the elevation or height of Mt. Everest.

Use the function F(3)<br> F(x) =(1/5)^x<br> A.)1/15<br> B.)1/125<br> C.)3/5<br> D.)3/125

nalin [4]

Here is your answer

B) 1/125

REASON:

Given,

$F (x)={(1/5)}^{x}$

for F (3)

Putting x=3, in above function we get

$F (3)= {(1/5)}^{3}= 1/125$

(-4,19) and (8,-2) whats the slope intercept

Sever21 [200]

Answer:

slope = -7/4

Step-by-step explanation:

Plug the points into this formula: $\frac{y2 - y1}{x2 - x1}$

Plug in

$\frac{-2 - 19}{8 - (-4)} \\\\\frac{-21}{12} = -7/4$

The simplest form is -7/4

Hope this helps ya! Keep smiling!
