What is the equation of a line that is perpendicular to a line with a slope of 2 and passes

2 answers:

6 0

To find the equation of a perpendicular line, you first need to find the negative reciprocal of the slope given. The slope is -1/3, so the slope of the perpendicular line will be 3

Now we just need to find the y intercept using the point (3, 2) and you can plug the coordinates in and then solve for b. Let's see what that looks like.

y=3x+b

2=3*(3)+b

2=9+b

-7=b So now we know the y-intercept and slope. We just put them together now

y=3x-7

the ration in this traingle is x, x $\sqrt{3}$ , 2x, where 2x is the hypothenuse

the hypothenuse is 12

x=12/2=6

the other leg is 6 $\sqrt{3}$ =10.39

A toy company spends $20 for every doll it makes. Promotion of the dolls costs $400 and the company sells each doll for $30. How

Romashka-Z-Leto [24]

Answer:

$20d+400< 30d$

Step-by-step explanation:

we know that

The profit is equal to the number of dolls multiplied by the selling price minus the number of dolls multiplied by the cost of each doll minus the cost of the promotion of the dolls

To make a profit, the number of dolls multiplied by the selling price minus the number of dolls multiplied by the cost of each doll must be greater than the cost of the promotion of the dolls

Let

d -----> the number of dolls

The linear inequality that represent this problem is

$30d-20d > 400$

Adds 20d both sides

$30d > 20d+400$

Rewrite

$20d+400< 30d$

Every ride at the country fair costs the same amount. The cost of one ride is $2.25. The fair entry fee is $6.50. Lupe paid the

adell [148]

Answer:

Step-by-step explanation:

Step one:

given data

we are told that the cost of one ride is $2.25

the entry fee= $6.5

the linear function for the situation is represented by the equation of line

y=mx+c

Step two:

let x be the number of ride

given that x=7

substituting we have

y=2.25(7)+6.5

y=15.75+6.5

y=22.25

In all Lupe we have to pay $22.25
