Answer:

D. -3x + 18

Step-by-step explanation:

3x - 9y = 18

y = 1/3 x - 2  ... x intercept   0 = 1/3x -2        x=6

perpendicular line slope: - 1/(1/3) = -3 and (6,0) 0n the line

equation: (y-0)/(x-6) = -3

y = -3x +18

Answer:

-3x\4

Step-by-step explanation:

multiply the number 3x(-1/4)= -3/4x

the combine -3/4x to -3x/4

Answer:

6(x - 3)

Step-by-step explanation:

18(x−3)−6(x−3)2 =>

18x - 54 - 12 (x - 3 ) =>

18x - 54 - 12x + 36 =>

18x - 12x - 54 + 36 =>

6x - 18 or 6(x - 3)

both answers are good, althoguth this second one 6 (x - 3) should be the one that you are looking for

Answer:

  3. 1.8

  4. 66

Step-by-step explanation:

The common difference is the difference between a term and the one before it.

  5 -3.2 = 1.8

The common difference is 1.8.

__

The 8th term is found by putting 8 where n is and doing the arithmetic.

  a₈ = 10·8 -14

  a₈ = 80 -14 = 66

The eighth term is 66.

_____

Additional comments

The difference is only "common" if all pairs of adjacent terms have the same difference. When that is the case, any pair of adjacent terms can be used to find the common difference. The arithmetic is probably easier using ...

  6.8 -5 = 1.8

__

In question 4, the sequence has a first term of -4 and a common difference of 10. The sequence is ...

  -4, 6, 16, 26, 36, 46, 56, 66 . . . . the 8th term is 66.

The sequence of the terms is -7,-1+5, and +11. A series is a collection of sequences.

A sequence is a collection of items that have been arranged in a logical order, with members appearing either before or after each other.

Given equation ;

[tex]\rm a_n = a_{n-1}+6[/tex]

If,

[tex]\rm a_1 = -13[/tex]

The next term in the sequence is;

[tex]\rm a_2 = a_{2-1}+6 \\\\ \rm a_2 = a_{1}+6 \\\\ a_2 = -13 +6 \\\\ a_2 =-7[/tex]

[tex]\rm a_3 = a_{3-1}+6 \\\\ \rm a_3 = a_{3}+6 \\\\ a_3 = -7 +6 \\\\ a_3 =-1[/tex]

[tex]\rm a_4 = a_{4-1}+6 \\\\ \rm a_4 = a_{3}+6 \\\\ a_4 = -1 +6 \\\\ a_4 =+5[/tex]

[tex]\rm a_5 = a_{5-1}+6 \\\\ \rm a_5 = a_{4}+6 \\\\ a_5 = 5 +6 \\\\ a_5 =11[/tex]

Hence, the sequence of the terms is -7,-1+5, and +11.

Answer: 15.6

Step-by-step explanation: 2.6 x 6 = 15.6

Answer:

$15.60

Step-by-step explanation:

If buying a pound of something is $6 then 2 pounds is $12.

0.6 pounds would be $3.60

1 = $6

0.9 = $5.40

0.8 = $4.80

0.7 = $4.20

0.6 = $3.60

0.5 = $3.00

0.4 = $2.40

0.3 = $1.80

0.2 = $1.20

0.1 = $0.60

0 = $0.00

subtract by .60 or 60 cents

Answer:

They are similar using the angle-angle property.

Step-by-step explanation:

Since you know that 2 of the angles are congruent, you can use this to prove triangle similarity.

By AA similarity, triangle PQR similar to triangle STU.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

The two given triangles PQR and STU.

Here, ∠P=63° and ∠R=45°

In triangle STU, ∠S=63° and ∠U=45°

Now, ∠P=∠S=63° and ∠R=∠U=45°

Since angles of triangle are congruent

By AA similarity, ΔPQR similar to ΔSTU

Therefore, triangles are similar.

Answer:

It can be written as 0.25 in decimal form (rounded to 6 decimal places).

Step-by-step explanation:

Answer:

It is already in the simplest form, but you can convert It into many things.

Step-by-step explanation:

Make this into an improper fraction you: 1 x 4 + 1 then put the answer on the numerator and keep the denominator.

Mixed number = 5/4

Decimal = 1.25

because 1/4 = 0.25

and 1 is a whole number.

Answer:

24

Step-by-step explanation:

Answer:Thus 30% of 80 is (30/100) x 80 = 24.

Step-by-step explanation:

33oz = 100%

1% = 100%/100 = 33/100 = 0.33oz

59 - 33 = 26oz increase

how many % are these 26oz compared to the original 33oz ?

we need to see how often 1% fits into 26oz.

26/0.33 = 78.78787878...%

rounded this means a 79% increase of drinking water.

=======================================================

Explanation:

Use the distance formula to compute the length of each segment. For instance, the distance from point F to point G is the length of segment FG.

I'll show the steps on finding the length of FG

[tex]F = (x_1,y_1) = (-5,10)\\\\G = (x_2,y_2) = (-2,2)[/tex]

[tex]d = \text{distance from F to G}\\\\d = \text{length of segment FG}\\\\d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\d = \sqrt{(-5-(-2))^2+(10-2)^2}\\\\d = \sqrt{(-5+2)^2+(10-2)^2}\\\\d = \sqrt{(-3)^2+(8)^2}\\\\d = \sqrt{9+64}\\\\d = \sqrt{73}\\\\d \approx 8.544\\\\d \approx 8.5\\\\[/tex]

The length of segment FG is approximately 8.5 units. The other side lengths are handled in the same way. As an alternative, you can use the pythagorean theorem.

---------------------

Once you determine all six lengths, note we have the following three pairs of corresponding congruent sides:

Because we have three pairs of equal sides, this means we can use the SSS (side side side) congruence theorem to prove the triangles are congruent. In other words, we have two identical triangles. One triangle is a rotated and reflected copy of the other.

Answer:

5 students are in a club.

Step-by-step explanation:

To do 20% of 25, you must first move the % until all numbers are on the right side of the decimal.

Observe: 20% ---> 0.20 aka 0.2

Now, you must take 0.2 and multiply it by 25 to get 20% of 25.

0.2 x 25 = 5
