Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
(x₁, y₁) - given point

For the answer to the question above, I'll provide a solution to my answer below.
(4 / 5) + (3 / x) = (1/2)
<span>x cannot equal 0 </span>
<span>(4x + 15) / 5x = 1/2 </span>
<span>2(4x + 15) = 5x </span>
<span>8x + 30 = 5x </span>
<span>3x = -30 </span>
<span>x = -10
</span>I hope my answer helped you. Feel free to ask more questions. Have a nice day!
Answer:
The equation of the line will be:
Step-by-step explanation:
Given the points
Finding the slope




We know that the value of y-intercept can be obtained by setting x=0, and solving for y
Here,
at x = 0, the value of y = 0
Thus,
y-intercept = b = 0
We know the slope-intercept form of the line equation is

where m is the slope and b is the y-intercept
now substituting m = 0 and b = 0 in the slope-intercept form
y = mx+b
y = 0(x) + (0)
y = 0+0
y = 0
Therefore, the equation of line will be:
Answer:
Total magic cakes =300
chocolate cakes =90
so if you want the percentage of chocolate you will divide the number of chocolate cakes over the total number of chocolates
% of chocolate cakes = 90/300×100%
=30%
