F(2) = 4(2)² +4 (2) -2

zloy xaker [14]

Answer:

Step-by-step explanation:

4(2)² + 4(2) - 2

Use PEMDAS, which is Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction. In that order we evaluate.

Exponents first, since there is nothing else to do in the parenthesis.

4(2)² + 4(2) - 2

4(4) + 4(2) - 2

Next is Multiplication and Division

4(4) + 4(2) - 2

16 + 8 - 2

Lastly are Addition and Subtraction

16 + 8 - 2

16 + 6

Write the equation of the line with a slope of 1/2 that passes through the point (-6,10)

Katen [24]

Answer:

An equation is

$y = \frac{1}{2} x + 13$

Step-by-step explanation:

☆Since since we're given the slope, all we need to do is find the y-intercept.

☆The slope-intercept formula is: y = mx + b.

☆We are going to plug in according to the formula.

$y = mx + b \\ \\ 10 = \frac{1}{2} ( - 6) + b \\ 10 = - 3 + b \\ \frac{ + 3 = + 3 \: \: \: \: \: \: \: \: \: }{13 = b \: \: \: \: \: \: \: \: \: \: \: }$

☆We have everything we need, so now we put it together.
