MakcuM [25]3 years ago
3 0

Step-by-step explanation:

-12 = a(0+2)²-20

-12=4a -20

4a = 20-12

4a=8

a=2

y = 2x²+ 8x -12

=> y = 2 x² + 8 x + -12

2 , 8 , -12

The left and right page numbers of an open book are two consecutive integers whose sum is 23. Find these page number.
zavuch27 [327]

Answers: The page numbers are 11 and 12

==========================================================

Explanation:

Consecutive integers are ones that follow immediately after another. For example, the set {7,8,9,10} are consecutive.

Let,

  • x = first page, some positive whole number
  • x+1 = second page, follows immediately after page x

Adding those two said pages will lead to 23

first + second = 23

(x) + (x+1) = 23

2x+1 = 23

2x = 23-1

2x = 22

x = 22/2

x = 11 is the first page

x+1 = 11+1 = 12 is the second page

Check: 11+12 = 23 which confirms the answers.

OlgaM077 [116]

Answer:

=17

Step-by-step explanation:

We need the slope and the y-intercept to find the equation of the linear model.

This line goes through (0,28) and (1,26), so the slope is

\frac{26 - 28}{1} = -2

1

26−28

​  =−2

The equation that best describes this model is

\widehat{y} = -2x + 28

y

​  =−2x+28

Plug in x = 5.5 in the above equation to get

​\widehat{y}

y

​   ​=−2x+28

=(−2)(5.5)+28

=−11+28

=17

Based on this equation, the date in April her flowers will bloom if the average temperature in March is
