Write the four terms of the sequence f(n) = 12 + 3(n-1)



9,12,15,18,21



12,15,18,21,24



-12,-9,-6,-3,0

Answers

Answer 1
Answer:  B) 12, 15, 18, 21, 24

Explanation:

The given arithmetic sequence is of the form

a+d(n-1)

where 'a' is the first term and d is the common difference

In the case of

12+3(n-1)

we have a = 12 as our first term and d = 3 as the common difference. This means we start with 12 and add on 3 to each term to get the next one

12+3 = 15

15+3 = 18

18+3 = 21

21+3 = 24

and so on.

Side note: your teacher asks about the first four terms, but each answer choice lists five terms.

m/4 - 3 = 6 + m/2

Answers

Answer:

m = -36

Step-by-step explanation:

Solve for m:

m/4 - 3 = m/2 + 6

Hint: | Put the fractions in m/4 - 3 over a common denominator.

Put each term in m/4 - 3 over the common denominator 4: m/4 - 3 = m/4 - 12/4:

m/4 - 12/4 = m/2 + 6

Hint: | Combine m/4 - 12/4 into a single fraction.

m/4 - 12/4 = (m - 12)/4:

(m - 12)/4 = m/2 + 6

Hint: | Put the fractions in m/2 + 6 over a common denominator.

Put each term in m/2 + 6 over the common denominator 2: m/2 + 6 = m/2 + 12/2:

(m - 12)/4 = m/2 + 12/2

Hint: | Combine m/2 + 12/2 into a single fraction.

m/2 + 12/2 = (m + 12)/2:

(m - 12)/4 = (m + 12)/2

Hint: | Make (m - 12)/4 = (m + 12)/2 simpler by multiplying both sides by a constant.

Multiply both sides by 4:

(4 (m - 12))/4 = (4 (m + 12))/2

Hint: | Cancel common terms in the numerator and denominator of (4 (m - 12))/4.

(4 (m - 12))/4 = 4/4×(m - 12) = m - 12:

m - 12 = (4 (m + 12))/2

Hint: | In (4 (m + 12))/2, divide 4 in the numerator by 2 in the denominator.

4/2 = (2×2)/2 = 2:

m - 12 = 2 (m + 12)

Hint: | Write the linear polynomial on the left hand side in standard form.

Expand out terms of the right hand side:

m - 12 = 2 m + 24

Hint: | Move terms with m to the left hand side.

Subtract 2 m from both sides:

(m - 2 m) - 12 = (2 m - 2 m) + 24

Hint: | Combine like terms in m - 2 m.

m - 2 m = -m:

-m - 12 = (2 m - 2 m) + 24

Hint: | Look for the difference of two identical terms.

2 m - 2 m = 0:

-m - 12 = 24

Hint: | Isolate terms with m to the left hand side.

Add 12 to both sides:

(12 - 12) - m = 12 + 24

Hint: | Look for the difference of two identical terms.

12 - 12 = 0:

-m = 24 + 12

Hint: | Evaluate 24 + 12.

24 + 12 = 36:

-m = 36

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of -m = 36 by -1:

(-m)/(-1) = -36

Hint: | Any nonzero number divided by itself is one.

(-1)/(-1) = 1:

Answer: m = -36

1) true or false: Two triangles with three pairs of corresponding congruent angles are congruent.

2) true or false: Two triangles with two pairs of congruent corresponding angles and three pairs of congruent corresponding sides are congruent.​

Answers

Step-by-step explanation:

TrueFalse

For two triangle to be congruent,there must be any three sides or angle including congruent

Congruent triangles have three pairs of corresponding sides that are congruent, while two triangles that have three pairs of corresponding congruent angles are similar and not necessary congruent. Therefore:

Statement 1 is FALSE.Statement 2 is TRUE.

Recall:

Two triangles having three pairs of corresponding sides have the same shape and size, and are congruent.Two triangles having three pairs of corresponding angles have the same shape but may have different sizes. They are rather similar.

1. When the two triangles have the three pairs of corresponding angles that are congruent, they can only be said to be similar. They have the same shape but may be of different sizes.

They will be congruent if all corresponding three pairs of sides of both triangles are congruent.

Therefore, statement 1 is FALSE.

2. Knowing that three pairs of corresponding sides of two triangles are congruent, it is enough to prove that both triangles are congruent to each other.

Therefore, statement 2 is TRUE.

The parallelogram pictured below has a perimeter of 129. Find the value of y.

Answers

Answer:

y = 2½ = 2.5

Step-by-step explanation:

From the question given above, the following data were obtained:

Perimeter = 129

Slant Side (a) = 10y – 9

Base (b) = 17y + 6

y =.?

The perimeter of a parallelogram can be obtained by using the following formula:

Perimeter = 2(a + b)

Thus, with the above formula, we can obtain the value of y as shown below:

Perimeter = 129

Slant Side (a) = 10y – 9

Base (b) = 17y + 6

y =.?

Perimeter = 2(a + b)

Perimeter = 2a + 2b

129 = 2(10y – 9) + 2(17y + 6)

Clear bracket

129 = 20y – 18 + 34y + 12

Collect like terms

129 + 18 – 12 = 20y + 34y

135 = 54y

Divide both side by the coefficient of y i.e 54

y = 135/54

y = 2½ = 2.5

Thus, the value of y is 2½ or 2.5

What is the slope of the two points (-2,7) and (4,-8)

Answers

Answer:

-15/6

Step-by-step explanation:

If you look at the first number in each point, the x coordinate, you see the 2nd point is 6 forward from the 1st point. Now the 2nd number is the y coordinate, and you can see it goes down 15 from the 1st coordinate. So y/x is the slope.

Answer: -2 1/2

Step-by-step explanation:

Slope= Yb-Ya/Xb-Xa

In this case= (-8-7)/(4- -2)

This equals -15/6

Simply to -2 1/2
