Answer:

D. Vertex (1, -25); intercepts x = -4, 6

Step-by-step explanation:

Vertex

x = -b/2a

x = - (-2)/2(1)

x = 2/2

x = 1

y = 1^2 - 2(1) - 24

y = 1 - 2 - 24

y = -25

Vertex (1, -25)

x-intercepts when y = 0

x^2 - 2x - 24 = 0

(x - 6)(x + 4) = 0

x - 6 = 0; x = 6

x + 4 = 0;x = -4

Answer

D. Vertex (1, -25); intercepts x = -4, 6

Write an ordered-pair rule for the translation in the sequence that maps AEFG to AE'F'G'. 4 Points ANSWER: Translation rule: (x,
Anastasy [175]

The translation rule is:

(x,y) \rightarrow (x + 4, y - 5)

  • F(1,4) is mapped to F'(5,-1), that is, 4 is added to the x-coordinate and 5 is subtracted from the y-coordinate.
  • G(2,2) is mapped to G'(6,-3), which is the same change as in F.
  • The same happens for E(-1,2), which is mapped to E'(3,-3).

Thus, the translation rule when <u>4 is added to the x-coordinate and 5 is subtracted from the y-coordinate</u> is:

(x,y) \rightarrow (x + 4, y - 5)

Let f(x) = x2 − 3x − 7. Find f(−3).
elena55 [62]

Answer:

f(-3) = 11

Step-by-step explanation:

To evaluate f(-3), substitute x = - 3 into f(x)

⇒ f ( − 3 )  =  ( − 3 )^ 2  −  3 ( − 3 )  −  7

= 9 + 9 − 7 = 11

hope this helps

sorry if wrong

At Grocery Mart, tomatoes are $2.75 per pound, or you can buy a 5
larisa [96]

Answer:

a) $2.75

b) $2.2

c) Second tomato option is better value option.

Step-by-step explanation:

First option to buy tomatoes = $2.75 per pound

Second option to buy tomatoes:

To buy a box which is a 5 pound box and the price is $11.

To find:

a) Unit price for the first tomato option.

b) Unit price for the second tomato option.

c) Better value option on the basis of price.

Solution:

Let the consider the unit here to be a pound.

So, we will find the price of tomato per pound to find the unit price of tomato.

a) Unit price of the first tomato option is : $2.75 per pound

b) Unit price of the second tomato option:

Price for 5 pounds = $11

Dividing both sides with 5 to find the price of 1 pound or unit price.

Price for \frac{5}{5} = 1 pound = \frac{\$11}5  = \$2.2

c) To find the better value option, we can compare the unit prices of the two tomato options.

Here, we have the two tomato options with unit prices as:

$2.75 and $2.2

Second tomato option has a lower unit price, therefore, <em>second option</em> is better value option on the basis of price.
