I would say Linear because there is no clear non linear pattern! alternatively, you could put the data into a spreadsheet and calculate the R value (pearson's coefficient) then see how strong the linearity is. In short, I would say Linear! hope that helps :)

Answer: non linear

Step-by-step explanation:

It’s difficult to tell because the dots are big and the scale is too small, but the plot should be a decreasing function with negative concavity until x=70 aprox where there is an assyptote. Then, after x=70 we only have one point so we don’t know how it continues.

Select the multiplication sentence that applies the associative property of multiplication to the example. Example: 6 × (4 × 2)

Sliva [168]

answer : D

A. (6 × 7) + 6 = 48

Associative property of multiplication . Here we have +6 . there is a + sign inbetween. so it does not comes under Associative property of multiplication

B. 6 × (4 + 2) = 36

Here we have 4 +2 . there is a + sign inbetween. so it does not comes under Associative property of multiplication

C. (6 + 4) × 2 = 20

Here we have 6 + 4 . there is a + sign inbetween. so it does not comes under Associative property of multiplication

D. (6 × 4) × 2 = 48

Here we have 6 times 4 times 2. so it comes under Associative property of multiplication

Find the value of x in the below complementary angle 3x(5x+2)

Natali [406]

Answer:

The value of x is 11

Step-by-step explanation:

Two angles are complementary if the sum of their measures is 90°

Let us use this rule to solve our question

∵ The angle of measure (3x)° and the angle of measure (5x + 2)°

are complementary angles

→ That means their sum equals 90°

∴ 3x + 5x + 2 = 90

→ Add the like terms in the left side

∵ (3x + 5x) + 2 = 90

∴ 8x + 2 = 90

→ Subtract 2 from both sides to move 2 from the left side to the right side

∵ 8x + 2 - 2 = 90 - 2

∴ 8x = 88

→ Divide both sides by 8 to find x

∵ 8x/8 = 88/8

∴ x = 11

∴ The value of x is 11
