Answer:

y = 14

Step-by-step explanation:

The sum of the angles in a triangle add to 180 degrees

50 + 2x+ 5y + 10 = 180

We know that 2x = 50 since they are the base angles of sides that have the same length, they must be the same

50 + 50 + 5y+10 =180

Combine like terms

110 + 5y =180

Subtract 110 from each side

110+5y-110 = 180-110

5y = 70

Divide each side by 5

5y/5 =70/5

y = 14

The concentration of a saline solution is given by the function <img src="https://tex.z-dn.net/?f=C%28x%29%3D%5Cfrac%7B0.2%7D%7B
katrin2010 [14]

Answer:

We have to add 1.86 L of water to make the solution 7% saline.

Step-by-step explanation:

The concentration of a saline solution is given by

                        C(x) = \frac{0.2}{1+x}

where x represents the amount of water used to dilute the solution.

We have to find how much water must be added to obtain a solution that is 7% saline.

If we see the equation we notice that as we add the value of x, the concentration of the solution decreases.

Here C(x) = 0.07

0.07 = \frac{0.2}{1+x}

Rearranging,

1 + x = \frac{0.2}{0.07}

1 + x = 2.86

x = 1.86 L

We have to add 1.86 L of water to make the solution 7% saline.

Helpp how do we know if an equation is a linear relation​
antoniya [11.8K]

Answer:

Simplify the equation as closely as possible to the form of y = mx + b. Check to see if your equation has exponents. If it has exponents, it is nonlinear. If your equation has no exponents, it is linear.

The domain is an interval. The domain is the function is (answer.)
Dmitriy789 [7]

Answer:

Domain :Set of all real values

Range : -5

Step-by-step explanation:

Here we see the blue line. Assuming it to be the graph of the function we are about to find Domain for.

Here we see that the graph is a straight line , parallel to x axis at y=-5

Hence the function will be

f(x)=-5

Also for every values of x, y =-5. Hence it is defined for all values of x. So the Domain is Set of All Real numbers

However,

For every value of x, the value of y is constant that is -5. Hence The range of f(x)=-5 is {-5}
