The slope in the equation of a line is the coeffient of x
the equation of a line and a point is
(y-y1)=m(x-x1)
where m is the slope so 3 is the slope

A 1,000 mL solution of acetic acid contains 26 mL of pure acetic acid. Find the percent concentration of this solution.
Mrac [35]

Given:

Total solution : 1000mL

Pure acetic acid = 26mL

To find:

The percent concentration of given solution.

Solution:

We know that,

\text{Percent concentration}=\dfrac{\text{Pure acetic acid}}{\text{Total solution}}\times 100

Putting the given values, we get

\text{Percent concentration}=\dfrac{26}{1000}\times 100

\text{Percent concentration}=\dfrac{26}{10}

\text{Percent concentration}=2.6

Therefore, the percent concentration of this solution is 2.6%.

Write the direct variation function given that y varies directly with x, and y = 1.5 when x = 5.
Cloud [144]

Answer:

y=0.3x

Step-by-step explanation:

Formula = K=\frac{y}{x}

y α x

y = kx

Where k is the constant of proportionality.

When y = 1.5; x = 5;

We substitute these known values in the equation,

y = kx

1.5 = k5

Dividing both sides of the equation by 5 to find the value for k, we have

1.5/5= k0.3/5

Therefore,

K = 0.3

Having found the value of k,

We substitute this value into the relationship

y = kx

Therefore we have,

y = 0.3x.

The direct variation function is therefore,

y = 0.3x.
