Answer:

y = 5.5x – 17

Step-by-step explanation:

Slope (m) = ΔY/ΔX=11/2 =5.5

When x=0, y = -17

I NEED HELP! ASAP, THIS IS SO HARD AND MY BRAIN HURTS, IF U HELP ME WITH OTHER QUESTIONS LIKE THIS ILL GIVE U 50+ POINTS

Dimas [21]

Answer:

24.3

Step-by-step explanation:

We need to follow the order of operations PEMDAS:

Parentheses
Exponents
Multiplication and Division (from left to right)
Addition and Subtraction (from left to right)

Carry out the operation in the parentheses first:

3³ + 14.7 ÷ 7 - (1.2 × 4)

⇒ 3³ + 14.7 ÷ 7 - 4.8

Now the exponent:

⇒ 3³ + 14.7 ÷ 7 - 4.8

⇒ (3 × 3 × 3) + 14.7 ÷ 7 - 4.8

⇒ 27 + 14.7 ÷ 7 - 4.8

Now, the division (there is no multiplication):

⇒ 27 + 14.7 ÷ 7 - 4.8

⇒ 27 + 2.1 - 4.8

Finally, carry out the addition and subtraction (from left to right)

⇒ 27 + 2.1 - 4.8

⇒ 29.1 - 4.8

⇒ 24.3

Describe the piecewise function below by evaluating the function for given values of the domain

tekilochka [14]

We have a piecewise function.
Therefore, to find the function, we must evaluate each domain separately.
We have then:

For $x \leq -2$ :
The function for this domain is:
$y = -3
$

For $-2 \ \textless \ x \leq 2$ :
The function for this domain is:
$y = mx + b
$
Where,
$b = -3

 m = (y2 - y1) / (x2 - x1)

 m = (1 - (-7)) / (2 - (-2))$
$m = (1 + 7) / (2 + 2)

 m = 8/4

 m = 2$
Substituting:
$y = 2x - 3
$

For $x\ \textgreater \ 2$ :
The function for this domain is:
$y = 5$
