Ab and bc form a right angle at point B. if a= (-3,-1) and B= (4,4) what is the equation of BC?

Vesnalui [34]

Answer:

Option C $-7x-5y=-48$

Step-by-step explanation:

step 1

Find the slope of AB

we have

A(-3,-1) and B(4,4)

The slope m is equal to

$m=(4+1)/(4+3)$

$m=5/7$

step 2

Find the slope of BC

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

$m1*m2=-1$

we have

$m1=5/7$

substitute

$5/7*m2=-1$

$m2=-7/5$

step 3

Find the equation of the line into slope point form

$y-y1=m(x-x1)$

we have

$m=-7/5$

$B(4,4)$

substitute

$y-4=-(7/5)(x-4)$

Multiply by 5 both sides

$5y-20=-7x+28$

$7x+5y=28+20$

$7x+5y=48$

Multiply by -1 both sides

$-7x-5y=-48$

ou need 1 1/4 cups of sugar to make 20 cookies. How many cups of sugar will you need to make 16 cookies? cups of sugar

frutty [35]

Answer:

To make 16 cookies you will need 1 cup of sugar.

Step-by-step explanation:

Given:

Sugar needed to make 20 cookies = 1 1/4 cups

To Find:

Sugar needed to make 16 cookies = ?

Solution:

For making 20 cookies 1 1/4 cups of sugar is used

So to make 1 cookie we need

=> $\frac{1\frac{1}{4}}{20}$

=> $\frac{\frac{5}{4}}{20}$

=> $\frac{5}{4} \times \frac{1}{20}$

=> $\frac{5}{80}$

=> $\frac{1}{16}$ cups of sugar

Now to make 16 cookies we need,

=> $16 \times \text{sugar needed to make one cookie}$

=> $16 \times\frac{1}{16}$

=> $\frac{16}{16}$

=> 1
