Janelle graphed a line through (−6, 5) that had a slope of −79. What is the y-coordinate of a point on the line that has an x-coordinate of 3?

Answers

Answer:

The value of the y-coordinate is -706

Step-by-step explanation:

The equation of a straight line is;

y = mx + c

where m is slope and c is t-intercept

Given the slope, we can write the equation as;

y = -79x + c

we need to get c

Just put in the x and y values of the given point

X = -6 and y = 5

5 = -79(-6) + c

5 = 474 + c

c = 5-474 = -469

So the complete equation of the line would

be ;

y = -79x - 469

To get the y-coordinate of the point, just insert the x value into the equation;

y = -79(3) - 469

y = -237 - 469 = -706

Answers

Answer:

34.1 minutes

Step-by-step explanation:

distance= 2miles,time=11 minutes

pace=velocity

velocity= distance/time

V= (2/11) miles/minutes

since the pace is maintained. then,

time taken to run 6.2 miles would be

time=distance/velocity

T= 6.2miles/(2/11)miles/minutes

T= [(6.2×11)/2]minutes

T= 34.1 minutes.

how far would a 4.0 cm tall object be located from a reflecting surface with a focal lenght that is equal to 5 cm if it is to create an image seen 15 cm behind the mirror. Determine the image size

Answers

Answer:

HERE IS YOUR ANSWER

Step-by-step explanation:

Use the mirror equation:

1/di + 1/do = 1/f

where di = -10 cm and f = +15 cm. (Note that di is negative if the image is virtual.)

Substitute and solve for do.

1/do + 1/(-10 cm) = 1/(15 cm)

1/do = 1/(15 cm) - 1/(-10 cm) = 5/(30 cm)

do = 6 cm

Hope it helps you

Joanne has 20 books on crafts and cooking. she has 6 more cookbooks than craft books. how many of each does she have?

Answers

Answer:

Crafts books: 7

Cookbooks: 13

Step-by-step explanation:

Let x be the crafts book

Let y be the cookbooks

Solve for x:

Plug x and y in: x + y = 20Re-write: y = x + 6Plug in x + 6 instead of y: x + x + 6 = 20Combine like terms: 2x + 6 = 20Subtract 6 from each side, so it now looks like this: 2x = 14Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 7

Solve for y:

Re-use an equation from above: y = x + 6Plug in the value of x: y = 7 + 67 + 6 = 13So, y = 13

Ryan has a collection of 216 baseball cards. He lets his brother have 1/3 Ryan has a collection of 216 baseball cards. He lets his brother have 1/3 of his collection and takes 27 cards to school to give his friends. How many baseball cards remain in Ryan's collection? 127 cards 90 cards 117 cards 126

Answers

Answer:

117 cards

Step-by-step explanation:

Total number of cards in the collection of Ryan = 216

Number of cards given to his brother = ⅓ of 216 = ⅓ × 216 = 216/3 = 72

Number of cards given to his friend at school = 27

Number of baseball cards that Ryan has remaining = 216 - (72 + 27)

= 216 - 99

Number of cards remaining = 117 cards

if someone helps me on this I'm giving them a lot of points,

Answers

Answer:

the distance from Fresno to San Francisco on the second map is 75cm

Step-by-step explanation:

The scale on the first map is 1 cm to 20 km

The distance from Fresno to SanFrancisco is 15 cm

1cm/20km = 15cm

The scale on the second map is 1 cm to 100 km.

1cm/100km = x

X= 15cm*100km/20km *1cm/1cm

X=15cm *5

X= 75 cm

the distance from Fresno to San Francisco on the second map is 75cm

Answer:

Step-by-step explanation:

You would use a^2+b^2=c^2

a^2+3^2=5^2

a^2+9=25 subtract nine from both sides

a^2=16

find the square root of 16 which is 4

so the other side of the triangle is 4

Answer:

4 cm

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the length of the 3 rd side, then

x² + 3² = 5²

x² + 9 = 25 ( subtract 9 from both sides )

x² = 16 ( take the square root of both sides )

x = [tex]\sqrt{16}[/tex] = 4

Find m angle MOP if m angle MON =4x+9 and m angle MOP =3x-3

Answers

Answer:

Step-by-step explanation:

Measure of ∠MOP is equals to 71.7°.

What are supplementary angles?

" Supplementary angles are those angles whose sum is equals to 180°."

According to the question,

∠MOP = 3x - 3

∠MON = 4x + 9

As ∠MOP and ∠MON has common arm OM.

Therefore, ∠MOP and ∠MON are supplementary angles.

As per definition of supplementary angles we have

∠MON + ∠MOP = 180°

Substitute the value of ∠MOP and ∠MON we get,

4x + 9 + 3x - 3= 180°

⇒7x - 6 = 180°

⇒7x = 174

⇒ x = 24.9 (round off)

Substitute the value of x in measure of ∠MOP we get,

∠MOP = 3(24.9) -3

= 71.7°

Hence, measure of ∠MOP is equals to 71.7°.

Answers

17 apples were green because it’s 25 percent of apples so it’s 68-17

1. You need to do percentages so to find 25% or 1/4 of 68 (68 is divisible by 4) that would be 17
2. There are 17 green apples
3. There are 51 red apples
4. 51-17= 34
