So we have y=-x-1 this is the same as y=-1(x+1) so it has a slope of -1 this means any line perpendicular will have a slope of 1. now we use this with the point and point slope formula.
recall point slope formula is y-y1=m(x-x1) where (x1,y1) is a point and m is the slope so we find
y-7=1(x-5) we can simplify this into y intercept form by solving for y
so
y=x-5+7
y=x+2
so the line perpendicular has a slope of 1 and a y intercept of 2! :)
Answer:
c) 5√2 cm
Step-by-step explanation:
A square with side length l has a perimeter given by the following equation:
P = 4l.
In this question:
P = 20
So the side length is:
4l = 20
l = 20/4
l = 5
Diagonal
The diagonal forms a right triangle with two sides, in which the diagonal is the hypothenuse. Applying the pytagoras theorem.
Lenght is a positive meausre, so
So the correct answer is:
c) 5√2 cm
Answer:
The total sale price that Gechina paid was $5,274.71.
Step-by-step explanation:
Given that Gechina Galvez shopped at a department store during the end-of-summer sale in which all luggage was marked down 35 percent, and she purchased a suitcase that regularly sells for $74.95, a garment bag that regularly sells for $8,000, and a tote bag that regularly sells for $39.99, in order to know the total sale price, the following calculation has to be made:
100 - 35 = 65
(8,000 + 74.95 + 39.99) x 0.65 = X
8,114.94 x 0.65 = X
5,274.71 = X
Therefore, the total sale price that Gechina paid was $5,274.71.
Answer:
