What's is an equation of the line that passes through the point(-3,-1) and is perpendicular to the line x-2y=6

katrin2010 [14]

Answer:

$y+1=-2(x+3)$

Step-by-step explanation:

Slope is negative reciprocal when two lines are perpendicular

m1=1/2 therefore m2=-2

The equation of the line in point-slope form is given as

$y-y_1=m_2(x-x_1)$

Here m=-2 and (x1, y1)=(-3, -1)

Therefore,

$y+1=-2(x+3)$

there are about 1.5 grams of fat in 1 tabespoon of humus.how many grams of fat are in 2 1/2 cups of hummus ?

Kipish [7]

We'll first we need to know the in 1 cup there is 16 tablespoon.
so we could multiply we need 2 1/2 cup so that is 16 (1cup) + 16 (1cup) +8 (1/2 cup)= 40 tablespoons... and 1 tablespoon is 1.5 grams of fat then we multiply 40 times 1.5 .... This is equal to 60 grams fat
So there is 60 grams of fat in 2 1/5 cups of hummus.
