Explanation:
"the quotient" means to divide.
"the quotient of 14" means 14 is going to be divided by something. So we can write:
14
÷
The something it will be divided by is "the difference between a number and -7".
Lets call "a number"
n
.
"the difference" means we are going to subtract something from
n
and what we are going to subtract is a
−
7
. We can write this as:
n
−
(
−
7
)
Putting this together gives:
14
÷
(
n
−
(
−
7
)
)
Or
14
n
−
(
−
7
)

graph the parabola y equals negative x squared + 3 to graph a parabola plot the vertex and four additional points two on each si

Nataliya [291]

You don't have the graph icon here, so we'll have to graph this parabola without it.

Your parabola is y = -x^2 + 3., which resembles y = a(x-h)^2 + k. We can tell immediately that this parabola opens down and that the vertex is (0,3).

Plot (0,3). Besides being the vertex, this point is also the max. of the function.

Now calculate four more points. Choose four arbitrary x-values, such as {-2, 1, 4, 5} and find the y value for each one. Plot the resulting four points. Draw a smooth curve thru them, remembering (again) that the vertex is at (0,3) and that the parabola opens down.

-8m - 12 > -5(m - 8) – 3(m - 7)<br> Write the solution to the inequality

horrorfan [7]

Answer:

No answer.

Step-by-step explanation:

- 8m - 12 > -5m + 40 - 3m + 21

combine terms

-8m - 12 > -8m +61

add 8m to both sides

-12 > 61

negative 12 is not greater than 61

Afirm works 7 days a week. Every employee must work exactly 3 full days and 4 half-days each week. A half-day can be either morn

Serhud [2]

Answer:

a) 560 (as you know)

Step-by-step explanation:

There are 7C3 = 35 ways to choose 3 full-time days from 7.

There are 2^4 = 16 ways to choose a half-day each day from the remaining 4 days.

The total number of possible schedules is ...

35×16 = 560

_____

nCk = n!/(k!(n-k)!)

7C3 = 7·6·5/(3·2·1) = 7·5 = 35

Graph f(x) = log5 (x-3).

Natali5045456 [20]

Step-by-step explanation:

We want to graph:

$f(x) =\log_{5}(x - 3)$

We first graph the parent function

$g(x) =\log_{5}(x)$

This parent function has x-intercept at (1,0) and it is asymptotic to the y-axis.

We then shift the graph of the parent function 3 units right, to obtain the graph of

$f(x) =\log_{5}(x - 3)$

The new x-intercept will be (4,0) and vertical asymptote will now be x=3.
