Answer:
5y = x + 11
Step-by-step explanation:
Given parameters:
Equation of the line ;
y = -5x + 1
Coordinates = (2, -1)
Find the equation of a line perpendicular;
Solution:
A line perpendicular to y = -5x + 1 will have slope that is a negative inverse of the given one.
Equation of a straight line is expressed as;
y = mx + c
y and x are the coordinates
m is the slope
c is the y-intercept
So, the slope of the new line perpendicular is 
;
Now let us find the y-intercept of the new line;
x = -1 and y = 2
2 = x (-1) + c
c = 2 + = 
The equation of the new line is;
y = x +
or multiply through by 5;
5y = x + 11
If he uses 85 tiles, 28 tiles will be black
<h3>Sequence and Pattern</h3>
The formation of the tiles of the floor follows an arithmetic sequence or pattern
The pattern is given as:
<h3>Formation of the tiles</h3>
Given that the total number of tile used is 85, and the black tile is always in the third position.
The highest number less than or equal to 85 that is divisible by 3 is 84.
Next, we divide 84 by 4
Hence, 28 of the tiles will be black

Answer:They spend $39.89
Step-by-step explanation:
Vampire:4•3.99=15.96
Zombie:2•1.04=2.08
3•0.79=2.37,2•3.49=6.98
Mummy:5•2.50=12.50
The Werewolf doesn’t buy anything
15.96+2.08+2.37+6.98+12.50=$39.89
Answer:
0.4
Step-by-step explanation:
1.6 - 1.2 = 0.4
D) 1 1/4
She needs 1/4 to make 1 batch so multiply that by 5 (or add 1/4, 5 times) 5 * 1/4 = 5/4 = 1 1/4
