Solve for x to make the inequality true

Mathematics
1 answer:
Anton [14]3 years ago
3 0

Answer: x>-17

Step-by-step explanation:

\frac{x}{-4} +9

Multiply by -4 on both sides.

(-4)(\frac{x}{-4} )+9

x+9>-8

When you multiply or divide by negative numbers, the inequality sign changes direction.

Subtract 9 on both sides to isolate x.

-9+x+9>-8-9\\x>-17

A 29- m tall building casts a shadow. The distance from the top of the building to the tip of the shadow is 33 . Find the length
prohojiy [21]

Answer:

About 17.7 meters.

Step-by-step explanation:

This can be solved by imagining the triangle formed by the building and its shadow. The hypotenuse of the triangle, the distance from the tip of the building to the tip of the shadow, is 34 meters, and one of the legs is 29 meters. Therefore, we can use the Pythagorean theorem to find that the third side is . Hope this helps!

16x⁴-4x²-4x-1 and 8x³-1<br>HCF​
IgorLugansk [536]

Answer:

We have expanded formula of (-4x-1)² = a²+2ab+b².

So, we write the formula in square form as (a+b)².

Since we have a²-b² in step 4. We further write this as (a+b)(a-b). This is the factor formula of a²-b².

As we had two terms in place of in (a+b)(a-b), we multiply the term 'b' with '+' and '-' sign respectively.  

Write the second expression given in the question.

Write the terms in the form of cube.

Write the factor formula of a³-b³) in the form of (a-b)(a²+ab+b²).

Write the H.C.F. (Highest Common Factor) of the given expressions by analysing the factors you generated in each expressions. Here, (4x²+2x+1) are the common factors.

Which of the following is the correct ratio for converting kilograms to grams
Brrunno [24]

Answer:

1000 Grams : 1 Kilogram or 1 Kilogram : 1000 Grams

Step-by-step explanation:

In the metric system the value of a kilogram is solved like:

Kg = \frac{g}{1000}

When converting from grams to kilograms, we solve it like:

g = \frac{kg}{0.0010000}

Let's take for example:

2 KG is how many grams?

We use the grams to kilograms formula like so:

g = \frac{2}{0.0010000}

Then we end up with:

g = 2000
