Answer:
<h3>There is a constant of variation in the equation and it is 750. This means that the amount olivia earns increases by $750 every week.</h3>Step-by-step explanation:
Given the equation y = 750x which represents the number of dollars y Olivia earns in x weeks, from the equation, it can be inferred that the number of dollars olivia earns is DIRECTLY PROPORTIONAL to the number of weeks. This relationship is therefore a direct variation.
In direct variation, increase in a variable will lead to corresponding increase in the other variable and vice versa by a factor known as the constant of variation.
For example if y is directly proportional to x, it is written mathematically as shown;
where k is the constant of proportionality.
comparing the general expression above with the equation in question,
y = 750x
k = 750
Therefore we can conclude that there is a constant of variation in the equation and it is 750. This means that the amount olivia earns increases by $750 every week.
Answer:
<h2>x + y - 2 = 0</h2>Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept.
Put the given y-intercept b = 2 and the coordinates of the point (1, 1) to the equation:
<em>subtract 2 from both sides</em>
The equation of a line:
The general form of an equation of a line:
Convert:
<em>add x to both sides</em>
<em>subtract 2 from both sides</em>
Answer:
second marble is blue and first marble is white is
Step-by-step explanation:
given data
two marbles
box = 1 blue, 3 white, 2 green, and 2 red marbles
solution
we get here second marble is blue and given that the first marble is white
= P(3c1 × 1c1) ÷ P(3c1 × 7c1) ................................................1
= 1c1 ÷ 7c1
= 1 ÷ 7
so second marble is blue and first marble is white is
