What is the y-value of the vertex of the function f(x) = –(x – 3)(x + 11)?The y-value of the vertex is

Answers

Answer 1

Answer: expand
f(x)=-1x^2-8x+33

x coordinate of vertex is -b/2a in the form ax^2+bx+c=y
a=-1
b=-8
-(-8)/2(-1)=8/-2=-4
plug back in to get y value

y=-(-4^2)-8(-4)+33
y=-16+32+33
y=49

y value is 49

B. $289.29
C. $140.79
D. $278.29

Answers

Answer:

Step-by-step explanation:

13per mile×1080 mile =140.79

Answer:

Step-by-step explanation:

if you at $24.74 * 6 = 148.5

then you take 1083 * .13 = 140.79

then add the two number to get 289.29

{-5, 5}

Answers

Answer:

{-5, 5}

Step-by-step explanation:

|x| = 5

We have both a positive and negative solution

x = 5 and x =-5

Answer:

x is in {-5, 5}

Step-by-step explanation:

The absolute value operator takes away the sign, making the result always positive.

So | -5 | = 5

but also | 5 | = 5

Hence two solutions.

Lisa is asked to draw a quadrilateral with the following specifications. adjacent angles are supplementary opposite angles are supplementary the measures of two adjacent sides are both 5 inches Which of the following statements about this quadrilateral is true.

Answers

Answer:

B (i do also slightly lean towards C, but i'm pretty sure it would be B because it gives a specific measurement)

Step-by-step explanation:

If all angles that are either adjacent or opposite are supplementary, all angles must be 90°

If at all times adjacent sides are 5 inches, all sides are equal.

Knowing this, it has to be a square because all angles would be 90° and all sides would be equal.

Laura wants to show 70 in tens.How many tens will she draw?How do you know?

sales tax and purchase price: suppose the sales tax rate in a certain state is is 8% how much sales tax is charged on a new car if the purchase price is $11,900?

Answers

To calculate the sales tax of an $11,900 purchase, we simply multiply the purchase prices by the sales tax rate.

8% is 8 parts of 100, which can be shown as a fraction with 8/100 or as a decimal with .08

Let's use the decimal in this case:

Sales Tax = purchase price x sales tax rate
Sales tax = 11,900 x .08
Sales tax = $952

So if the car was purchased at $11,900 in a state with an 8% sales tax rate, the sales tax would be $952 bringing the total cost of the car up to $12,852.
