Something like physics, you want to not have such a specific major because you can always change your mind later on. It might take around 10ish years, but that is a rough estimate.

Which of the following describes graphing y ≥ |x| + 4?
kolbaska11 [484]

Answer:

Translate  y=\left|x\right| up 4 units and shade inside the V

Step-by-step explanation:

we know that

The function y=\left|x\right| has the vertex at point (0,0)

The function y=\left|x\right|+4 has the vertex at point (0,4)

so

the rule of the translation is

(x,y)------> (x,y+4)

That means

The translation is 4 units up

The solution of the inequality  y\geq\left|x\right|+4

is the shaded area inside the V

see the attached figure to better understand the problem

therefore

the answer is

Translate  y=\left|x\right| up 4 units and shade inside the V

Order 34 × 102, 1.2 × 107, 8.11 × 10–3 and 435 from least to greatest.
andrey2020 [161]
I will assume that this question is about scientific notation (also assuming that the first number is 3.4*10^2), where you can arrange the numbers by the exponent of the 10, so from least to greatest:
8.11*10^{-3}, 3.4*10^{2}, 435, and 1.2*10^{7}

Add 0.0025 kg, 1750 mg, 2.25 g, and 825,000 μg, and express the answer in grams.
kozerog [31]

Answer:

6.75g

Step-by-step explanation:

The first step is converting everything to grams, by rules of three. Then we add.

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.

Unit conversion problems, like this one, is an example of a direct relationship between measures.

First step: 0.0025kg to g

Each kg has 1000g, so:

1kg - 1000g

0.0025kg - xg

x = 1000*0.0025 = 2.5g

0.0025kg = 2.5g

Second step:  1750 mg

Each g has 1000mg, so:

1g - 1000mg

xg - 1750mg

1000x = 1750

x = \frac{1750}{1000}

x = 1.75g

1750 mg = 1.75g

2.25g - OK

Third step: 825,000 μg to g

Each g has 1,000,000 ug, so:

1g - 1,000,000 ug

xg - 825,000 ug

1,000,000x = 825,000

x = \frac{825,000}{1,000,000}

x = 0.25g

825,000 μg = 0.25g

Final step: adding everyting

0.25g + 2.25g + 1.75g + 2.50g = 6.75g
