Solve the inequality 0 > –3x – 2x. A. x > –36
B. x > 1
C. x > 0
D. x > –28

Answers

Answer 1

Answer:

Answer:

Option C is correct.

Step-by-step explanation:

Given Inequality,

0 > -3x - 2x

To Find: Solution of the inequality.

Consider,

0 > -3x - 2x

Group like terms in RHS

0 > ( -3 - 2 )x

0 > -5x

transpose RHS to LHS and LHS to RHS

-5x < 0

Divide both sides by -5

we know that in inequality multiplying and dividing negative number sign of inequality changes.

So,

x > 0/(-5)

x > 0

Therefore, Option C is correct.

Answer 2

Answer: 0 > -3x - 2x...combine like terms
0 > - 5x ....divide both sides by -5
0/-5 < x
0 < x or x > 0

Find the length of the base of a square pyramid if the volume is 1,024 cubic inches and has a height of 12 inches.

Answers

Hello,

Let 's x the length of the pyramid:
V=x²*h/3
V=1024 and h=12
So x²*12/3=1024
==>x²=1024*3/12
==>x²=256
==>x²=16²
==> x=16 for (x=-16 must be exclude <0)

(x2 + 6x + 9) = (x + 3)

Turkey weigh 7kg how long to cook

Answers

If a turkey weighs 7kg or 14lbs, it must have a roasting time of 2 3/4 to 3 hours and a resting time of up to 60 minutes. This weight is good for 8 to 10 servings.

Roasting time is the time it is cooked inside the oven. Resting time is the time the turkey is taken out of the oven but left alone so that the heat inside the turkey will still continue to cook the meat within.

Roasting time varies on the weight of the turkey but the resting time has a maximum of 60 minutes.

3kg - 1 3/4 - 2 hrs.
4kg - 2 - 2 1/4 hrs
5kg - 2 1/4 - 2 1/2 hrs
6kg - 2 1/2 - 2 3/4 hrs
9kg - 3 1/2 - 4 hrs
11kg - 4 1/2 hrs

Find the inverse function of g(x) = 2x + 4.g -1(x) = 4x + 2
g -1(x) = 2x + 1/2
g -1(x) = 1/2 x - 2
g -1(x) = 2x - 4

Answers

Answer:

$g^(-1)(x)=(1)/(2)x-2$

Step-by-step explanation:

First, let's rename this as y = 2x + 4.

In order to find the inverse, switch the x and the y, then solve for the new y.

x = 2y + 4 so

2y = x - 4 and

$y=(1)/(2)x-2$

Putting it back into function notation:

$g^(-1)(x)=(1)/(2)x-2$

If two triangles are congruent which of the following statements must be true? CHECK ALL THAT APPLYA. The triangles have the same size but not the same shape.
B. The triangles have the same size and shape
C. The corresponding sides of the triangles are congruent.
D. The corresponding angles of the triangles are congruent.

Answers

The correct answers are choices B, C, and D. Here is an explanation for each choice: B. All congruent figures are exactly the same size and shape. This is what makes one figure congruent to another. C. If the figures are the same size and shape, then the corresponding sides will also be congruent. D.If the figures are the same size and shape, then the corresponding angles will also be congruent.

If two triangles are congruent, then they have the same shape and size. The correct options are B, C, and D.
