Answer: Interval notation. When using interval notation, domain and range are written as intervals of values. For f(x) = x 2, the domain in interval notation is: D: (-∞, ∞) D indicates that you are talking about the domain, and (-∞, ∞), read as negative infinity to positive infinity, is another way of saying that the domain is "all real numbers." The range of f(x) = x 2 in interval notation is: R: [0, ∞) R indicates that you are talking about the range.

fred thinks of a number that is greater than 110 and less than 120. he can make his number with same number of hundreds,tens and

VashaNatasha [74]

The number Fred thinks of is 111

Solution:

Given that, Fred thinks of a number that is greater than 110 and less than 120

He can make his number with same number of hundreds,tens and ones

To find: Fred's number

Given that the number is greater than 110 and less than 120

The possible numbers are:

111 , 112, 113, 114, 115, 116, 117, 118, 119

But he can make his number with same number of hundreds,tens and ones

So the numbers in ones, tens and hundreds place are same

So the only possible number is 111

Thus the number Fred thinks of is 111

Help is required, I am stuck

Natalija [7]

Answer:

see explanation

Step-by-step explanation:

Given

x² + 4x - 7 = 0 ( add 7 to both sides )

x² + 4x = 7

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(2)x + 4 = 7 + 4

(x + 2)² = 11 ( take the square root of both sides )

x + 2 = ± $\sqrt{11}$ ( subtract 2 from both sides )

x = - 2 ± $\sqrt{11}$

Thus

x = - 2 - $\sqrt{11}$ ≈ - 5.32 ( to 2 dec. places )

x = - 2 + $\sqrt{11}$ ≈ 1.32 ( to 2 dec. places )

Put into slope intercept form:(-4, 1); m= -2/3

zaharov [31]

Y = mx + b
slope(m) = -2/3
(-4,1)...x = -4 and y = 1
now we sub and find b, the y int
1 = -2/3(-4) + b
1 = 8/3 + b
1 - 8/3 = b
3/3 - 8/3 = b
-5/3 = b

so ur equation is : y = -2/3x + (-5/3) which can be written as : y = -2/3x - 5/3
