The equation of the perpendicular line to the given line is: y = -5/4x - 30.
<h3>What is the Equation of Perpendicular Lines?</h3>
The slope values of two perpendicular lines are negative reciprocal of each other.
Given that the line is perpendicular to y = 4/5x+23, the slope of y = 4/5x+23 is 4/5. Negative reciprocal of 4/5 is -5/4.
Therefore, the line that is perpendicular to it would have a slope (m) of -5/4.
Plug in m = -5/4 and (x, y) = (-40, 20) into y = mx + b to find b:
20 = -5/4(-40) + b
20 = 50 + b
20 - 50 = b
b = -30
Substitute m = -5/4 and b = -30 into y = mx + b:
y = -5/4x - 30
The equation of the perpendicular line is: y = -5/4x - 30.

Answer:
k = 1.75
Step-by-step explanation:
5 - 4k = -7
k = 1.75, because if you subtract 4 from both sides, you are left with 1.75 = -7.
Answer:
SU=5 the first option.

I did the assignment.
Answer:
2.8- 4.4n- 2n + 7 = -6.4n + 9.8
Step-by-step explanation:
combined like term:
-4.4n - 2n = -6.4n
2.8 + 7 = 9.8
so all you do is combined together and got -6.4n + 9.8
A man's inheritance money = $1200
Given :
He shared his inheritance between his 3 sons in the ratio 1:3:6
Then, the money the first son got :





▪︎Thus, the first son inherited $120.
Money the second son got :





▪︎Thus, the second son inherited $360.
Money the third son got :





▪︎Thus, the third son inherited $720.
We know that :
The largest share = $720
The smallest share = $120
Difference between the largest and smallest share :


<h3> ●=> Therefore :</h3>
▪︎<em>The difference between the largest and smallest share = 600</em>
