Does (3,7) make the inequality 2x+2y<20 true
dangina [55]

Answer:

False

Step-by-step explanation:

Substitute x and y with the numbers in the coordinate pair.

Just as a recap-

3 is the x value

7 is the y value

2(3) + 2(7) = 20

20 < 20

This is not true since 20 = 20

Hence, the answer is false

In circle K , diameter CD is drawn and point E is located on the circle such that CE=16 and DE=30 .What is the length of the rad
egoroff_w [7]

Answer:

The length of the radius of the circle K is 17\ units

Step-by-step explanation:

we know that

The triangle CDE is a right triangle with the 90 degree angle at point E

so

Applying the Pythagoras Theorem

Find the length of CD (diameter of the circle K)

CD^{2}=CE^{2}+DE^{2}

substitute the values

CD^{2}=16^{2}+30^{2}

CD^{2}=1,156

CD=34\ units

Find the radius

Remember that the radius is half the diameter

so

r=34/2=17\ units

Divide 8x2 + x2 +32x+4 by x2 +4.
Len [333]

Answer:

\frac{8 {x}^{3}  +  {x}^{2}  + 32x + 4}{ {x}^{2} + 4 }  = 8x + 1

Step-by-step explanation:

Assuming, we the given polynomial is

8 {x}^{3}  +  {x}^{2}  + 32x + 4

and the divisor is

{x}^{2}  + 4

Then , the polynomial division is shown in the attachment.

This implies that:

\frac{8 {x}^{3}  +  {x}^{2}  + 32x + 4}{ {x}^{2} + 4 }  = 8x + 1
