What is 17+6-6+6 divided by 6 + 17.

alina1380 [7]

Answer:

$\boxed{\bold{1}}$

Using Pedmas rule:

$\dashrightarrow \sf \dfrac{17+6-6+6}{6+17}$

subtract: 6-6 = 0

$\dashrightarrow \sf \dfrac{17+6}{23}$

simplify the following

$\dashrightarrow \sf \dfrac{23}{23}$

the numerator and denominator cancels out

$\dashrightarrow \sf 1$

The mean temperature for the first 7 days in January was 3 °C.

g100num [7]

Answer:

3.5 °C

Step-by-step explanation:

To find the answer multiply 3 and 7 to get the sum of the temperatures in the first seven days.

3 x 7 = 21

Add 21 and 8 together to get the sum of the temperatures in the first 8 days.

21 + 8 =29

Divide 29 by 8 to get the mean temperature for the first eight days.

29 ÷ 8 = 3.5

3.5 °C

What are the solutions to the quadratic function. f(x) = x^2+4x-12

Rudiy27

Answer:

2, -6

Step-by-step explanation:

x^2 + 4x - 12

A = 1

B = 4

C = -12

i used the "X" method to solve for the solutions. i think it's easier than using the quadratic formula but it doesn't always work

for the "X" method you have to multiply your A value and your C value together so 1 x (-12) = -12. that is going to be the top part of the X

the bottom part of the x will be your B value which is 4

we have to find multiples of -12 that will also add to 4

so -2 and 6 multiply to -12 but also add to 4 so we know these numbers will work

i added added two drawings to show how i found the solutions using the "X" method and the quadratic formula

Is this relation a function? explain

Anton [14]

Answer:

A function is a relation in which no two ordered pairs have the same first element. A function associates each element in its domain with one and only one element in its range. Solution: a) A = {(1, 2), (2, 3), (3, 4), (4, 5)} is a function because all the first elements are different.
