Line v passes through points (1, 17) and (9, 10). Line w is perpendicular to v. What is the slope of line w?

1 answer:

5 0

To find the slope of line v, divide the change in y-values by the change in x-values:

17 - 10 / 1 - 9
7 / - 8

Slope of line v = -7/8

Now, slopes of perpendicular lines are negative reciprocals of each other, therefore:

The slope of line w = 8/7

Hope this helps.

The Downtown Community Barbecue served 280 dinners. A child’s plate cost $2.60 and an adult’s plate cost $9.50. A total of $1,79

Romashka-Z-Leto [24]

Answer:

the number of child plates and adults plates were served is 125 and 155 respectively

Step-by-step explanation:

Let us assume the child plate be x

And, the adult plates be y

Now according to the question

x + y = 280 .................(1)

2.60x + 9.50y = 1797.50 .............(2)

Now multiply by 2.60x in equation (1)

2.60x + 2.60y = 728

2.60x + 9.50y = 1797.50

-6.90y = -1069.50

y = 155

So, x = 280 - 155

= 125

hence, the number of child plates and adults plates were served is 125 and 155 respectively

Which value for x makes the sentence true?<br><br> 3/4x + 4 = 7

Aleks04 [339]

Answer:

(x) = 4

Step-by-step explanation:

3/4 (x) + 4 = 7

3/4 (4) + 4 = 7

0.75 (4) + 4 = 7

3 + 4 = 7

7 = 7

7-x/3=-1-x/8 I'm in 8th grade and I can't figure this out

antiseptic1488 [7]

Answer: x = 38.4

Step-by-step explanation:

7-x/3 = -1-x/8

1. Add 1 to both sides

8-x/3 = -x/8

2. Add x/3 to both sides

8 = x/3 - x/8

3. Multiply x/3 by 8/8 and x/8 by 3/3 to get the same number under the quotient

8 = 8x/24 - 3x/24

4. calculate the difference between 8x/24 - 3x/24

8 = 5x/24

5. Multiply both sides by 24/5, and there is the answer

38.4 = x

If Eric can paint $3$ cars in $4$ hours and $2$ trucks in $5$ hours, then how long, in hours, would it take him to paint $4$ car

deff fn [24]

Answer:

47/6

Step-by-step explanation:

Given that :

Time taken to paint 3 cars = 4 hours

Time taken to paint 2 trucks = 5 hours

How long will it take him to paint 4 cars and a truck

If 3 cars = 4 hours ;

Then ;

1 car = (4/3)hours

If 2 trucks = 5 hours

Then;

1 truck = (5/2) hours = 2 1/2 hours

Time required To paint 4 cars :

4 × (4/3) = 16/3 hours

Time required to paint 1 truck :5/2 hours

Total time required :

(16/3 + 5/2) = (32 + 15) / 6 = 47/6
