Answer:

Expression = 2 × 7 + 3 + 3

Evaluation of the expression = 20

Step-by-step explanation:

Number of laps Glenn swam every morning = 2

Number of days for which he swam these laps = 7 days

⇒ Number of laps swam in a week = 2 × 7

Number of laps swam with his friend on Tuesday = 3

Number of laps swam with his friend on Thursday = 3

So, Expression that show the number of laps he swam during the week = 2 × 7 + 3 + 3

By evaluating the above expression, the total number of laps he swam that week = 14 + 3 + 3 = 20 laps

Write an exponential function for the value, y, after x years
Anon25 [30]

Step-by-step explanation:

<u>Step 1:  Set x equal to 0 to find the y-int</u>

y = 10000(1 - 0.40) → Not an exponential equation

y=10000(1-0.40)^0 → 10,000 → Works for first test

y = 10000(1-0.60)^0 → 10,000 → Works for first test

y = 10000(1+0.40)^0 → 10,000 → Works for first test

<u>Step 2:  Set x equal to 1</u>

y=10000(1-0.40)^1 → 6,000 → Works for second test

y = 10000(1-0.60)^1 → 4,000 → Does not work for the second test

y = 10000(1+0.40)^1 → 14,000 → Does not work for the second test

Answer:  The answer is Option B

Directions: Solve <br> I think you cross multiply but I'm not really sure where to go from there.
Vlada [557]
I'm fairly sure they want you to cross multiply then graph. This will give you 'zeroes' which are solutions for x
if you graph (4x^3+3x^2)= z it'll give you a zero at -0.75 which means x= -3/4

Which car can travel at the slowest rate? Plz help fast
grigory [225]

Answer:

D


Step-by-step explanation:

Let's find unit rate of each (number of miles traveled in 1 hour). For that we will divide the distance by time to get the unit rate.

Note: rate=\frac{Distance}{Time}


(A)

rate = \frac{300}{4}=75 mph (miles per hour)

(B)

rate = \frac{450}{6}=75 mph

(C)

rate = \frac{750}{10}=75 mph

(D)

rate = \frac{800}{12}=66\frac{2}{3} mph


<u>As we can see, the first 3 rates are same, 75 mph, and the last one is 66\frac{2}{3} mph. So clearly, the last rate is the slowest.</u>

D is the right answer.
