y=k(x+2)²-20
and -12=k*(0+2)²-20==>k=8/4=2

olganol [36]

Answer:

y = x^2 + 6       given equation

y = m x + b        equation of straight line required

dy/dx = 2 x       tangent to given curve

dy/dx = slope = 2 * 5 = 10

Thus our line must be of the form

y = 10 x + b

31 = 10 * 5 + b       at the point required

b = 31 - 50 = -19

Then our final equation becomes

y = 10 x - 19

The change in temperature is -28°F

So, Option D is correct.

Step-by-step explanation:

Temperature at day time = 72°F

Temperature at night = 44°F

What number represents the change in number?

Change in temperature = Temperature at night - Temperature at Day

Change in temperature = 44°F-75°F

Change in temperature = -28°F

The change in temperature is -28°F

So, Option D is correct.

Jet001 [13]
The first number - x
The second number is 7 more than the first - x+7
The third number is 2 more than 4 times the second - 4(x+7)+2
The sum of the numbers is 85.

x+x+7+4(x+7)+2=85 \\&#10;x+x+7+4x+28+2=85 \\&#10;6x+37=85 \ \ \ |-37 \\&#10;6x=48 \ \ \ |\div 6 \\&#10;x=8 \\ \\&#10;x+7=8+7=15 \\&#10;\\ 4(x+7)+2=4 \times 15+2=60+2=62

The numbers are 8, 15 and 62.
