What is the equation of the line perpendicular to –x + y = 7 and passing through (-1, -1)?

1 answer:

4 0

Y = x + 7
m1 = 1
m1 × m2 = - 1
1 × m2 = - 1
m2 = - 1

- 1 = - 1(-1) + c
- 1 = 1 + c
c = - 2
y = - x - 2
x + y = - 2
- x - y = 2

the answer is the 2nd one

The ratio of red cars to blue cars in a parking lot was 5:3 . If there was 40 red cars , how many blue cars were there ?

Bas_tet [7]

The answer is x equals 24
you set up a proportion new over old
so for red cars 40 over 5
since we don’t know the new for blue cars we’ll use x
so x over 3
we then make them equal to each other
40 x
—- = —-
5 3
cross multiply, then we get
120=5x
isolate the x by dividing 5 from both sides to get 24

The length of a rectangle is 5.5 feet. If the area is 44 square feet, what is the width of the rectangle, in feet?

vlabodo [156]

So area is length times width therefore
A=LW
44ft^2=5.5W
divide both sides by 5.5
44/5.5=Width=8 feet
