Answer:

a greater-than negative 21 and one-third

Step-by-step explanation:

3/4a>-16

divide both sides by 3/4

a>-16*4/3

a>-64/3

a>-21 1/3

so then

a greater-than negative 21 and one-third

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

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

$r=34/2=17\ units$

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:

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