Mathematics
1 answer:
Elenna [48]4 years ago
4 0

Answer:

Variable Y is equal to 7.5.

Step-by-step explanation:

First, open the brackets:

18 + 20y - 8 = -140

Second, subtract 18 and add 8 from/to both sides.

20y = -140 - 18 + 8

20y = -150

Third, divide by 20.

y = 7.5

Let f (x) = 3x − 1 and ε > 0. Find a δ > 0 such that 0 < ∣x − 5∣ < δ implies ∣f (x) − 14∣ < ε. (Find the largest
s344n2d4d5 [400]

Answer:

This proves that f is continous at x=5.

Step-by-step explanation:

Taking f(x) = 3x-1 and \varepsilon>0, we want to find a \delta such that |f(x)-14|

At first, we will assume that this delta exists and we will try to figure out its value.

Suppose that |x-5|. Then

|f(x)-14| = |3x-1-14| = |3x-15|=|3(x-5)| = 3|x-5|< 3\delta.

Then, if |x-5|, then |f(x)-14|. So, in this case, if 3\delta \leq \varepsilon we get that |f(x)-14|. The maximum value of delta is \frac{\varepsilon}{3}.

By definition, this procedure proves that \lim_{x\to 5}f(x) = 14. Note that f(5)=14, so this proves that f is continous at x=5.

Starting at home, Michael traveled uphill to the gift store for 24 minutes at just 10 mph. He then traveled back home along the
kondaur [170]
We can figure out how long Michael's trip took by realizing that 30 mph is 3 times 10 mph.  Because of this, the trip home will take 1/3 the amount of time it took to go up the hill.  This makes the equation 24 + 8 = 32 minutes for the whole trip.

Now we need to figure out how long the trip was.  We can do this by multiplying 10 minutes by 24/60, which equals 4.  This means that Michael went 4 miles there, and 4 miles back.  So Michael went a total of 8 miles.

Now we know that Michael went 8 miles in 32 minutes.  Now, we multiply 8 by 60/32.  This gives us 15, so Michael went 15 miles per hour on average in the trip.

Which expression is equivalent to absolute value of 8 + absolute value of -7
anzhelika [568]

Answer:

8+7

Step-by-step explanation:

Absolute value is when you calculate how far away the number is from zero.

Since 8 is 8 spaces away from zero, then the absolute value of 8 is 8.

Since -7 is 7 spaces away from zero, then the absolute value of -7 is 7.

So, in conclusion, an equivalent expression can be 8+7
