Answer:

Step-by-step explanation:

1*12=12 1*20=20

2*6=12 2*10=20

3*4=12 4*5=20

both have a similar multiple of 4, so k must be 4.

Factors of 12 : 1, 2, 3, 4, 6, 12

Factors of 20: 1, 2, 4, 5, 10, 20

In both lists of factors, 4 is in common. Therefore, the value of K is 4 because it can divide into both 12 and 20 without a remainder. 2 is also another possible value of K.

4 Three intersecting lines form triangle BCE as shown below.

Lapatulllka [165]

Answer:

A, C, E

Step-by-step explanation:

Options:

A. m∠C + m∠E = m∠A

Correct. Exterior angle equals to sum of non-adjacent interior angles.

B. m∠D + m∠F = m∠B

Incorrect. Exterior angles have greater value.

C. m∠B + m∠C + m∠E = 180°

Correct. Interior angles of a triangle sum to 180°

D. m∠B + m∠C + m∠D = 180°

Incorrect. Angles C and D sum to 180°

E. m∠A + m∠ B = m∠E + m∠F

Correct. Both sides of equation refer to straight angle.

F . m∠B + m∠C + m∠ E = m∠A + m∠D + m∠F

Incorrect. Some of interior angles is not equal to sum of exterior angles.

Yanka [14]

Solution

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the formula for slope

$m=\frac{y_2-y_1}{x_2-x_1}$

STEP 2: Pick two points

STEP 3: Find the unit price per cup

Since 4 cups cost $5, one cup will cost

$\frac{5}{4}=\text{ \$}1.25\text{ per cup}$

Therefore, the answer is $1.25

Average Rate of Change: $\displaystyle \frac{f(b) - f(a)}{b - a}$

Step-by-step explanation:

Step 1: Define

Interval -1 ≤ x ≤ 3

a = -1, b = 3

f(a) = f(-1) = 4

f(b) = f(3) = -4

Step 2: Find Average

Substitute in variables [ARC]: $\displaystyle \frac{f(3) - f(-1)}{3 + 1}$
Substitute: $\displaystyle \frac{-4 - 4}{3 + 1}$
[Fraction] Subtract/Add: $\displaystyle \frac{-8}{4}$
[Fraction] Divide: $\displaystyle -2$
