Which answer is an equation in point-slope form for the given point and slope?
Point: (5, 9); Slope: 2
y-5= 2 (2 +9)
y-9=2(x+5)
y+9= 2(2-5)
y-9=2(x – 5)

Answers

Answer 1

Answer:  y-9=2(x-5)

Step-by-step explanation: The point (5,9) satisfies the equation:

y-9=2(x-5)  for (5,9)?

9-9=2(5-5) ?

0 = 0  YES

Slope of 2?  Rewrite:  

y-9=2(x-5)

y = 2(x-5)+9

The slope is 2  YES

what's the question

.
Aiden buys ice cream and apples at the store.
He pays a total of $15.05.
• He pays a total of $3.80 for the ice cream.
• He buys 3 bags of apples that each cost the same amount.
Write and solve an equation which can be used to determine x, how much each bag
of apples costs.

Answers

Answer:

Equation: y = 3x + 3.80

Cost of each bag: $3.75

Step-by-step explanation:

y = 3x + b

y = $15.05

x = cost of each bag

b = $3.80

3 = # of bags

15.05 = 3x + 3.80

11.25 = 3x

3.75 = x

The equation to determine x is y = 3x + 3.8

and cost of each apple bag is $3.75.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

Total amount paid by Aiden = $15.05

Total amount paid for ice cream =  $3.80

Number of bags of apple = 3

So if x is the amount of each apple bag and y is the total amount paid by Aiden,

So,Cost of apple bags = 3x

And total amount = 3x + 3.8

or y = 3x + 3.8

this is the equation to determine x.

Now since, total amount paid is $15.05

⇒ 15.05 = 3x + 3.8

or,3x = 15.05 - 3.8

or 3x = 11.25

⇒ x = 11.25/3

⇒ x = $3.75

Thus,the equation to determine x is y = 3x + 3.8

and cost of each apple bag is $3.75.

Answer:

x = 12.2;  angles are 77.6 and 102.4 total to 180

Step-by-step explanation:

The equations they are giving you for the two angles he was correct about.  When a line intersects two parallel lines, the angles on the opposite sides of the transverse line will equal 180 degrees.

So those two equations when added together must equal 180 degrees.

(5x + 16.6) + (9x - 7.4) = 180

Rearrange the equation

5x + 9x + 16.6 - 7.4 = 180

Add the x values together and subtract the regular numbers

14x + 9.2 = 180

Subtract 9.2 from both sides

14x = 170.8

Divide both sides by 14

x=12.2

The top angle in your drawing is 5x + 16.6  or

5 ( 12.2) + 16.6 = 77.6 degrees

The bottom angle in your drawing is 9x - 7.4 or

9 ( 12.2) - 7.4  = 102.4

Both angles added together is 77.6 + 102.4 = 180

Answer:

×=25 ; angle = 107 degree

Step-by-step explanation:

if a transversal line intersect two parallel lines then the sum of two consecutive exterior angles is 180 degrees.

The two consecutive exterior angles are 3x+32 and x+48.

3x+32+x+48=1803x+32+x+48=180

4x+80=1804x+80=180

4x=180-804x=180−80

4x=1004x=100

x=25x=25

The value of x is 25.

The measure of two consecutive exterior angles are

3x+32=3(25)+32=1073x+32=3(25)+32=107

x+48=25+48=73x+48=25+48=73

The measure of the larger angle is 107 degrees.

Jamal has two trails. the first trail is 5 1/3 miles long, and the second trail was 1 3/4 times as long as the first trail. how many miles did Jamal walk?

Answers

Answer:

The correct answer is Jamal hiked [tex]14\frac{2}{3}[/tex] miles.

Step-by-step explanation:

To solve this math problem, you will need to convert mixed numbered fractions, into improper fractions.

To do that, you will need to multiply the whole number with the denominator (Ex: 5 × 3 = 15), then when you receive the answer, add the answer with the numerator (Ex: 15 + 1 = 16), finally, you should receive a new answer, and to finalize the improper fraction, you always need to keep the denominator the same (Ex: The denominator is 3 so use the new answer as a numerator replacement. [tex]\frac{16}{3}[/tex])

--

After you have converted all the mixed numbers into improper fractions in the math problem, you are then able to use multiplication.

--

But first we have to calculate how long the second trail was.

[tex]\frac{7}{4} *\frac{16}{3} =7*\frac{4}{3} =\frac{28}{3} =9\frac{1}{3}[/tex] miles. Then, convert the mixed number into improper. ([tex]\frac{28}{3}[/tex])

--

Now add the number of miles of both trails.

[tex]\frac{16}{3} +\frac{28}{3} =\frac{44}{3} =14\frac{2}{3}[/tex]

With the result as: [tex]14\frac{2}{3}[/tex]

Answers

Considering they're getting 2 more each wave, we can apply simple math to this.

6+2 and onwards,

0+3 and onwards until it surpasses the first value.

I calculated this, and it seems it takes around 6 minutes to catch up to the friend at 18 exercises.

It will take you 6 minutes to catch up to your friend.

Given that when you started your homework assignment, your friend already had 6 exercises done.

You can do about 3 exercises per minute, whereas your friend can only do 2 exercises per minute.

So, your friend is ahead by 6 exercises, and you can complete 3 exercises per minute while your friend can complete 2 exercises per minute.

This means you're gaining on your friend's lead at a rate of 3 - 2 = 1 exercise per minute.

To catch up to your friend's lead of 6 exercises, you'll need 6 minutes, because you'll be closing the gap by 1 exercise per minute.

So, it will take you 6 minutes to catch up to your friend.
