Describe the x-values at which f is differentiable.​
Sedbober [7]

Answer:

Step-by-step explanation:

Differentiability at a point implies no sudden changes in the slopes from one side to the other; that is, the derivative must have the same value.

Differentiating x^2 - 6 and 6 - x^2, we get 2x = -2x, whose only solution is zero (0).  The two halves of the given function have the same slope (0) at x = 0.

Mrs. Crosland asked students to factor the expression 282
Solnce55 [7]

Well formatted version of the question can be found in the picture attached below :

Answer:

Both Carlos and Irene

Step-by-step explanation:

Given the expression (28x - 8)

Carlos : 2(14x - 4)

Danny : 7(4x - 1)

Irene : 4(7x - 2)

The factored expression Given by Carlos, Irene and Danny can be expanded to check if it gives the same expression as that Given in the question :

Carlos :

2(14x - 4)

2*14x - 2*4

28x - 8

Danny :

7(4x - 1)

7*4x - 7*1

28x - 7

Irene :

4(7x - 2)

4*7x - 4*2

28x - 8

From.the expanded solutions obtained ;

Both Carlos and Irene's solution corresponds to the factored form of the original equation and are Hence correct

The table shows the values of y for each value of x. x y 2 1 3 1 4 -3 3 -3 Part A: Does the table represent a relation that is a
LUCKY_DIMON [66]
Part A:

The given values in form of ordered pairs are:
(2,1), (3,1), (4,-3), (3,-3)

A relation can be a function if one value of x is paired with exactly one value of y. In this case, x value of 3 is paired with two y values 1 and -3. So this relation is not a function.

Part B:

f(h) = 15h + 5
f(8) can be found by substituting h=8 in above equation. 
So,
f(8) = 15(8) + 5 = 125
h represents the number of hours and f(h) represents the earnings of Kylie. So f(8) shows that Kylie earned $125 from 8 hours of work in the cafe

Part C:

For r hours of work, we can write:
f(r) = 15r + 5
So, the ordered pair can represent this relation as:
(r, f(r))
or
(r, 15r+5)

Find three consecutive integers whose sum is 558
SIZIF [17.4K]
Those are 185, 186 and 187

What you do is create this system of equations:

x+y+z=558  (three integers add up to 558)
x+1=y  (they are consecutive, so that is translated as a number+1)
y+1=z (same logic as before)

And then you just resolve that system.
