Answer:

m = 20

Step-by-step explanation:

Hi there! I'm glad I was able to help you!

There's only one step to solving for the variable, but first, I'd like to flip the equation over so that it's easier to solve.

m - 5 = 15

Now we're ready to solve.

Our first (and only) step: Add 5 to both sides of the equation.

m - 5 + 5\\= 15 + 5\\

The top part cancels itself out, since negative 5 plus a positive 5 gives us zero, nothing.

Now, we are left with 15 + 5, which leaves us with:

m = 20

I hope this helped you! Leave a comment below if I could help you with anything else! :)

Rewrite the following equation in standard form and determine if there is a solution.
Debora [2.8K]

Answer:

| x + 4 |  = -1    No solution

Step-by-step explanation:

                                                 3 | x + 4 | + 12 = 9

Subtract 12 from both sides:         3 | x + 4 |  = -3

Divide both sides by 3:                     | x + 4 |  = -1

Absolute value cannot be negative, so there is no solution.

Suppose the value R(d) of d dollars in euros is given by R(d)-d The cost P(n) in dollars to purchase and ship n purses is given
S_A_V [24]

<u>Corrected Question</u>

Suppose the value R(d) of d dollars in euros is given by R(d)=\dfrac67 d. The cost in dollars to purchase and ship n purses is given by P(n)=66n+23. Write a formula for the cost, Q(n) in euros to purchase and ship n purses.

Answer:

Q(n)=\dfrac67(66n+23)

Step-by-step explanation:

The value R(d) of d dollars in euros is given by R(d)=\dfrac67 d

Therefore:

R(1)=\dfrac67

T$hat is, 1  dollars =\dfrac67$ euros

The cost P(n) in dollars to purchase and ship n purses is given by:

P(n) = 66n+23.

Therefore, the cost, Q(n) in euros to purchase and ship n purses

=\dfrac67 \cdot P(n)\\Q(n)=\dfrac67(66n+23)

An equation of a function y(t) is shown.
Sav [38]
From the given function, to explain the correct answer I will plot the graph for :
y(t)=-t^2+14t-40
thus the graph will be as shown in the figure:
From the graph we deduce that the correct statement is:
y'(t)=-2t+14=0
thus
t=7
thus
y(7)=0
thus the correct statement is:
<span>c. The average rate of change over the interval 6≤t≤8 is 0</span>
