Answer 2

Answer:

Jared did not get the correct answer. The solution to his equation is k = 3, giving 3, 4, and 5 as the three integers. However, 3 and 5 are not even integers. He should have used the equation:

[tex]\displaystyle k+(k+2)+(k+4) = 4k[/tex],

which gives us k = 6, and the correct answer 6, 8, and 10.

Step-by-step explanation:

Jared wanted three consecutive even integers, whose sum is 4 times the first integer.

He let k represent the first integer and wrote:

[tex]k+(k+1)+(k+2)=4k[/tex]

We can solve this first. Combine like terms:

[tex]3k+3=4k[/tex]

So:

[tex]k=3[/tex]

This means that our sequence will be 3, 4, and 5, which is not correct since we have odd integers.

Jared did not get the correct answer. The solution to his equation is k = 3, giving 3, 4, and 5 as the three integers. However, 3 and 5 are not even integers. He should have used the equation*:

[tex]\displaystyle k+(k+2)+(k+4) = 4k[/tex],

which gives us k = 6**, and the correct answer 6, 8 , and 10.

To verify, 6 + 8 + 10 = 24.

And 6(4) = 24, so our answer is correct.

**To solve, we can combine like terms:

[tex]3k+6=4k[/tex]

So:

[tex]k=6[/tex]

*The reason we use (k + 2) instead of (k + 1) is because (if k is an even number), then adding 2 guarantees another even number. If we added only 1, we will get odd numbers.

The captains of the soccer team describe ordering identical T-shirts for the team. Bindi says the total cost is $192. Gina says the cost is 8t, where t is the number of T-Shirts. Which person tells how much each T-shirt costs? How do you know?

Answers

Answer:

Both of them.

Step-by-step explanation:

Gina says the cost is 8t, which means you can easily find out the cost of each t-shirt if you know the the total cost too. Bindi says the total cost was 192, which is completely useless on its own, but paired with Gina's info, you can get the answer. Divide 192 by 8, and you get the cost of each t-shirt.

what are the like terms in the expression 8+x^2-4x^3+5x+2x^2?​

Answers

Answer:

B. x^2x2 and 2x^22x2

Step-by-step explanation:

The expression given is:

8+ x^2 - 4x^3 + 5x+ 2x^28+x2−4x3+5x+2x2

Like terms are terms in which their variables and the power of the variables (exponents) are the same.

While it is not necessary that the coefficient of the variables are the same, the power of the variables must be the same.

In that case, the like terms in the expression given are x^2x2 and 2x^22x2 .

Note: The question says 8+ x^2 - 4x^3 + 5x+ 2x^28+x2−4x3+5x+2x2 but the option has -4x^2−4x2 .

In case its actually -4x^2−4x2 instead of -4x^3−4x3 , then,

 -4x^2−4x2 is also a like term and the answer will be D.

Point (7,12) is rotated 1260° counterclockwise about the origin. What is the X-coordinate of the point after this rotation?

Answers

Given:

Point (7,12) is rotated 1260° counterclockwise about the origin.

To find:

The  x-coordinate of the point after this rotation.

Solution:

If a point is rotated 360 degrees then its coordinates remains unchanged.

If a point is rotated 180 counterclockwise about the origin degrees, then

[tex](x,y)\to (-x,-y)[/tex]

We know that,

[tex]1260^\circ=1080^\circ+180^\circ[/tex]

[tex]1260^\circ=3\times 360^\circ+180^\circ[/tex]

After [tex]3\times 360^\circ[/tex] rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.

[tex](7,12)\to (-7,-12)[/tex]

The point (7,12) becomes (-7,-12) after rotation of  1260° counterclockwise about the origin.

Therefore, the x-coordinate of the required point is -7.

A projector displays an image on a wall. The area (in square feet) of the projection is represented by x^2-8x+15
a. write a binomial that represents the height of the projection
b. find the perimeter of the projection when the height of the wall is 8 feet​

Answers

Answer:

a. (x - 5) ftb. 16 ft

Step-by-step explanation:

The area given:

x² - 8x + 15

a. The height is the factor of the area:

x² - 8x + 15 = x² - 3x - 5x + 15 = x(x - 3) - 5(x - 3) = (x - 3)(x - 5)

The width is x - 3, so the height is x - 5

b. The perimeter formula:

P = 2(x - 3 + x - 5) = 2(2x - 8) = 4x - 16

The height of the wall is 8 ft:

x = 8

The perimeter is:

P = 4*8 - 16 = 32 - 16 = 16 ft

Brian bought 215 pounds of strawberries. In the afternoon his brother ate 56 of the strawberries. How many pounds of strawberries did his brother eat?

Answers

Hi there!

Step By Step:

We know that 215 pounds are about 215 strawberries since every strawberry are about 1 pound.

Let think about this... 215 pounds are 215 strawberries.

If his brother ate 56 of the strawberries, it means that his brother ate 56 pounds of the strawberry.

We can also think like this... 56/215

Final Result: 56 pound sof strawberries.

joe finished his english assigments in 1/3 hours. Then he completed his chemistry assigment in 1/8 hours. What is the total amount of time joe spent doing these two assigments as a fraction in simplist form./ Aleks

Answers

To answer, we need to add the two fractions. However, to add them, they need to have a common denominator (the number on bottom). One easy way to do this is to multiply both so they are the same number. Use the opposite number! Then, you can add the numbers straight across. You will most likely need to simplify. If you have any further questions, let me know!
The lowest common denominator would be 24 for these 2 fractions...so change 1/3 into 8/24, and 1/8 into 3/24. Add them together and you see that it took him 11/24 hours to do both assignments. That won’t simplify any, so 11/24 should be your answer.

What is the output of the function when the input is 10? On the graph plot this point and label its coordinates

Answers

Answer:

Output value = 20

Step-by-step explanation:

Graph of any function is made up of two values → Values on x axis and Values along y axis.

x values represent the input values and y values represents the output values.

For every x value there is a y value because of which the data set is called to a function.

In other words, a function can't have two output values for a single input value.

If the input value of function is = 10

Then for x = 10, out value (along y axis) will be = 20

Therefore, Output value of the given function is 20.
