WILL GIVE BRAINLIEST! Find the equation of a line that passes through (-5,-2) and the intersection of the lines x+3y=0 and 4x-4y

-13=0
Mathematics
1 answer:
Verdich [7]2 years ago

Answer:

y + 2 = -0.069(x-+5)

Step-by-step explanation:

SInce the two lines intersects, we will equate it

Multiply x + 3y = 0 by 4;

4x + 12y = 0

4x-4y-13 = 0,

Subtracts both

12y +4y + 13 = 0

16y = 13

y = 13/16

get x;

x + 3(13/16) = 0

x = -39/16

The point of intersection is (0.8, -2.4) and (-5,-2)

Get the equation;

m = y2-y1/x2-x1

m = -2+2.4/-5-0.8

m = 0.4/-5.8

m = -0.069

Get the equation;

y - y0 = m(x-x0)

y - (-2)= -0.069(x-(-5))

y + 2 = -0.069(x-+5)

A company purchased​ 10,000 pairs of​ men's slacks for ​$19.36 per pair and marked them up $22.33 What was the selling price of
masha68 [24]

Answer:

$41.69

Step-by-step explanation:

The computation of the selling price of the each pair of slacks is as follows:

Given that

Cost = $19.36 per pair  

Markup = $22.33

As we know that  

Markup = Sell Price - Cost

So,  

Sell Price = Cost + Markup

= $19.36 + $22.33

= $41.69

Hence, the selling price is $41.69

PQ is parallel to RS. PR and QS are perpendicular to PQ and RS the ratio of the lengths of PR and QS is......
Lady bird [3.3K]

\frac{PQ}{PR} = \frac{RS}{QS} → \frac{PR}{PQ} = \frac{QS}{RS}

the ratio of PR to QS is 1:1 because they are congruent (equal)

If you draw a picture, you will see that PQRS is a parallelogram.

mihalych1998 [28]

Answer: 5%

Step-by-step explanation:

A meteorologist predicted that Monday's hight temperature would be 76F and on Monday, the temperature reached 80F.

The percentage error will be

Percentage error=

(Exact value-Forecasted value)/exact value x 100

= 76-80/80 × 100

= -4/80 × 100

=4/80 × 100

= 400/80

= 5%

The percentage error is 5%.
