In a triangle the length of two sides are 1.9m and 0.7m. What is the length of the third side, if you know that it should be a w

monitta

Answer:

their sum: 2.8m

their difference: 1.2m

the third side's length should be smaller than their sum, larger than their difference

it could be: 1.3-1.4-1.5-1.6-1.7-1.8-1.9-2-2.1-2.2-2.3-2.4-2.5-2.6-2.7 but since it has to be a whole number, 2m is the only eligible answer.

The pressure at sea level is 1 atmosphere and increases at a constant rate as depth increases. When Sydney dives to a depth of 2

mylen [45]

Answer:

Step-by-step explanation:

We are told that pressure at sea level is 1 atmosphere and increases at a constant rate as depth increases.

We are provided two points as (0,1) and (23,3.3). To find function's formula we will find the line which passes through these points.

First of all we will find slope of this line.

Now we will find equation of this line in slope intercept form.

Our equation for this line will be .

Now let us write this for x as a function of p,

Therefore, our function's formula will be p(x) = 0.1x + 1.

Systems of equations and inequalities<br> solving systems by elimination<br> {y= -x+1<br> {y= 4x-14

kodGreya [7K]

Answer:

x = 3 , y = -2

Step-by-step explanation:

Solve the following system:

{y = 1 - x | (equation 1)

y = 4 x - 14 | (equation 2)

Express the system in standard form:

{x + y = 1 | (equation 1)

-(4 x) + y = -14 | (equation 2)

Swap equation 1 with equation 2:

{-(4 x) + y = -14 | (equation 1)

x + y = 1 | (equation 2)

Add 1/4 × (equation 1) to equation 2:

{-(4 x) + y = -14 | (equation 1)

0 x+(5 y)/4 = (-5)/2 | (equation 2)

Multiply equation 2 by 4/5:

{-(4 x) + y = -14 | (equation 1)

0 x+y = -2 | (equation 2)

Subtract equation 2 from equation 1:

{-(4 x)+0 y = -12 | (equation 1)

0 x+y = -2 | (equation 2)

Divide equation 1 by -4:

{x+0 y = 3 | (equation 1)

0 x+y = -2 | (equation 2)

Collect results:

Answer: {x = 3 , y = -2
