(03.06 MC)Solve the equation for the letter r: d = rt

Neporo4naja [7]

The equation for r: d = rt would be 'r equals d over t.'

How, you might ask? Well, let's consider this example:

You might already know what d = rt stands for... "Distance equals rate times time", so if you divide the two sides by 't', you would come up with r = d/t. So that would finalize as your answer for this question.

10. Triangle PQR has vertices P(5, -1), Q(0, 8), and R(7, 5). It is translated right 3 units and up 6 units. Find the coordinate

Brrunno [24]

P' (8,5)
Q' (3,14)
R' (10, 11)

Why: Anything that is translated left or right you will be changing the x axis, if the translation is right, you add, if its left, you subtract. If the translation is up or down, its going to change the y axis. Down means you subtract from the y axis, up means you add to the y axis.

What is the value of y in the formula shown when x = 4/5?

Pavlova-9 [17]

4(4/5) + √(4/5) + 0.2 - 5(4/5)

= 16/5 + (2√5/5) + (1/5) - 4

= (16 + 2√5 + 1 - 20)/5

= (2√5 - 3)/5 or 0.29442719

: The You Move It Company (YMI) advertises that the cost to rent a moving truck for one day is $40 plus $1.99 for each mile the

mars1129 [50]

Part A: For 100 miles, the cost will be same for both companies.

Part B: Alex should use Drive and Move company as it will cost him less money.

Step-by-step explanation:

Given,

Starting amount of YMI= $40

Per mile charges = $1.99

Let,

x be the number of miles.

y be the total charges.

y = 1.99x+40 Eqn 1

Starting amount of DM = $60

Per mile charges = $1.79

y=1.79x+60 Eqn 2

Part A:

For same charges;

Eqn 1 = Eqn 2

$1.99x+40=1.79x+60\\1.99x-1.79x=60-40\\0.20x=20$

Dividing both sides by 0.20

$\frac{0.20x}{0.20}=\frac{20}{0.20}\\x=100$

For 100 miles, the cost will be same for both companies.

Part B:

Total miles = x = 150

Putting x=150 in Eqn 1

y=1.99(150)+40

y=298.5+40

y=$338.50

Putting x=150 in Eqn 2

y=1.79(150)+60

y=268.5+60

y=$328.50

Alex should use Drive and Move company as it will cost him less money.
