Answer:

11 and 1/8

Step-by-step explanation:

We can do this in the format of PEMDAS

Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction

10 + <u><em>(2 × 3</em></u>)^{2} ÷ 4 × \frac{1}{2} ^{3}

Let's do the parenthesis first

10 + 6^{2} ÷ 4 ×<u><em> </em></u>\frac{1}{2} ^{3}<u><em> </em></u>

Now we can do the fraction with the exponent second

10 +<u><em> </em></u>6^{2}<u><em> </em></u>÷ 4 ×  \frac{1}{8}

Now we can do the other exponent

10 + <u><em>36 ÷ 4</em></u> × \frac{1}{8}

Now we can divide the 36 and 4

10 + <u><em>9 × </em></u>\frac{1}{8}<u><em> </em></u>

Now we can multiply the 9 and  \frac{1}{8}

10 + \frac{9}{8}<u><em></em></u>

And we can convert the improper fraction to a mixed number

10 + 1 1/8

And now we can add them up, the 2 whole numbers and the fraction stays the same

11 1/8

Hope this helped!

Find all the frist differnce and explian your answer
Sever21 [200]

Answer: No this is not a linear function as the y values have different first differences.

Step-by-step explanation:

First we look at the x values. We start off and look at the second x value and subtract the first x value from it (That would be 1-0) and that equals to 1. Then we look at the third x value and subtract the second x value from it (2-1) and that equals to 1. Then we look at the fourth x value and subtract the third x value from it (That would be 3-2) and that is 1. Next we look at the fifth x value and subtract the fourth x value from it (That would be 4-3) and that is 1.

Now we look at the y values and do the same thing as with the x values. We start off and look at the second y value and subtract the first y value from it (That would be 1-0) and that equals to 1. Then we look at the third y value and subtract the second y value from it (4-1) and that equals to 3. Then we look at the fourth y value and subtract the third y value from it (That would be 9-4) and that is 5. Next we look at the fifth y value and subtract the fourth y value from it (That would be 16-9) and that is 7.

Even though the x values all have the same first differences, the y values do not and so this cannot be a linear function.

I hope this helps. Tell me if something doesn't make sense.

Julie and her friend went to the movies and bought one jumbo popcorn and two chocholate chip cookies for 5$. Marvin and his frie
makvit [3.9K]
Let j = cost of one jumbo popcorn, and c = cost of one chocolate chip cookie.

Then, based upon the given info, 1j + 2c = $5.

Also, 3j + 5c = $14.50

Let's solve this system of equations using addition/subtraction:

Mult. the first equation by -3, to obtain   -3j - 6c = -$15

Now add this result to the 2nd equation:   

-3j - 6c = -$15
3j + 5c = $14.50
----------------------
     -c = -$0.50, or c = $0.50.       Since   3j + 5c = $14.50, subst. $0.50 for c 
lets us find j:

3j + 5($0.50) = $14.50, so 3j = $12.00.  Thus, j = $4.00.


Jumbo popcorn is $4/bag, and choc. chip cookies $0.50 each.

What is the equation of the line in y=mx+b format? BRAINLIST WILL BE REWARDED
harkovskaia [24]

Answer:

y = 2/5x - 1

Step-by-step explanation:

There are a couple of different ways to figure this out, but since you have a graph, the fastest way is to count the slope, or m in the formula, by counting the rise (units up) over run (units to the right), which is 2/5. Then, find the value of b by finding the y-intercept on the graph, or -1.

Please help me(20 points will give brainliest!!!)
goblinko [34]

Answer:

A. Vertex is ( -1, 16)

B. Do they mean y-intercept for vertical intercept? That is (0,14)

C. X-intercepts are

(-3.838, 0) and (1.828, 0)

Step-by-step explanation:

plug the equation into desmos. It will graph and give you the info.

To find y-int, plug in 0 for x. This gives you the point 0, 14.

You can also use the quadratic equation to find the x-intercepts.
