What i s y= 2/7x-4 written in standard form

1 answer:

4 0

Standard form is ax + by = c y = 2/7x - 4 y + 4 = 2/7x 4 = 2/7x - y Multiply everything by 7 to get rid of fraction. 28 = 2x - 7y Answer: 2x - 7y = 28

What is the constant of proportionality? 48= 4k

inna [77]

Answer:

The constant of proportionality is 12.

Step-by-step explanation:

Let's take a look at the formula give to us:

48=4k

First, we have to isolate the variable, K, by dividing 4 on both sides.

48/4=4/4 k

48/4=12

12=k

We can check the answer by plugging it back into the equation:

12*4=48

48=48

Hence, the variable k equals 12.

Calculate the area shaded

Rudiy27

Answer:

7.722 cm^2

Step-by-step explanation:

Step 1: Find the area of the square.

Area of square = s^2, where s = side
6^2 = 36 cm^2

Step 2: Find the area of the circle.

We are given the diameter of the circle as 6 cm, so the radius must be 3 cm.
Area of circle is $\pi r^2$ , so now we plug in and simplify.
$3.142 * 3^2$
$3.142 * 9$
$28.278$

Step 3: Subtract area of circle from area of square.

$36 - 28.278$
$7.722$

Therefore, the area of the shaded region is 7.722 cm^2.

Which polynomial lists the powers in descending order? A. –10 + 4x3 – 4x5 + 2x4 + x7 B. x7 – 4x5 + 2x4 + 4x3 – 10 C. x7 + 4x3 +

Artist 52 [7]

The answer for the exercise shown above is the option B, which is: $x^{7} -4 x^{5} +2 x^{4} +4 x^{3}- 10$
The explanation is shown below:
To list the powers of the polynomial given in the problem above in descending order, you must write the terms from the highest degree to the lowest degree. You have that the highest degree is $7
$ and the lowest degree is $0
$ (Because $-10 x^{0} =-10(1)=-10$ . Therefore, you have that the correct option is the option B.
