Answer:
sq root of 64 = 8, sq root of 81 = 9, 8 and 9
Step-by-step explanation:
Since Sq root of 64 = 8 and Sq root of 81 = 9 it is known that sq root of 66 is between 8 and 9
Answer:
0
Step-by-step explanation:
Use the slope formula: m = 
m = 
The slope of the line is 0.
Answer: The second one
Step-by-step explanation:
response/25=x/100 and then you solve for x
Answer:
2 10/16 or 2 5/8
Step-by-step explanation:
You can add the whole numbers first, so 1+1=2
Now add the remaining fractions: 5/16 +5/16=10/16.
2+10/16=2 10/16 or 2 5/8.
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.
