If f (x) = StartRoot x EndRoot + 12 and g (x) = 2 StartRoot x EndRoot, what is the value of (f – g)(144)
Luda [366]

The value of (f-g)(144) is 0

Step-by-step explanation:

We are given:

f(x)=\sqrt{x}+12\,\,and\,\,\\ g(x)=2\sqrt{x}

We need to find value of (f-g)(144)

We will put x=144 for both f(x) and g(x)

(f-g)(144)=f(144)-g(144)\\=\sqrt{144}+12-(2\sqrt{12})\\=12+12-(2(12)\\=24-24\\=0

So, the value of (f-g)(144) is 0

Y/3 - 4 = -1 solve for y
Marysya12 [62]

Answer:

y=9

Step-by-step explanation:

First we need to solve al addition and subtraction by performing the inverse operation. In this case, we need to add to reverse the subtraction

y/3 -4= -1

y/3= 3

Now we solve all multiplication and division again using the inverse operation, which in this case is multiplication, because the variable is being divided.

y/3=3

y=9

Thus we get that the value for y is 9.

Hope this helped!

Btw you're very pretty! <3

<u>Congruency</u> property relates to two or more <em>triangles</em> with similar <em>dimensions</em>, and internal<u> angles</u>. So that the required <u>statements</u> to complete the proof are:

1. <em>definition</em> of a <u>straight</u> angle.

2. <u>subtraction</u> property of equality

3. <em>corresponding</em> sides of <u>similar</u> triangles are <u>proportional</u>

4.<u> transitive</u> property of <em>equality</em>.

The <u>intersection</u> of two or more lines forms a number of <em>angles</em> which depends on the <u>number</u> of lines involved. These <u>angles</u> formed may have <em>similar</em> or<em> different </em>properties.

When two or more <u>triangles</u> have <em>similar</em> lengths of <u>sides</u> and measure internal <u>angles</u>, it can be said that they are congruent. Thus they have some <u>common</u> properties.

Therefore, the appropriate <u>statements</u> to answer the given <em>question </em>are stated below:

  • <em>Definition</em> of a <u>straight</u> angle.
  • <u>Subtraction</u> property of equality.
  • <em>Corresponding</em> sides of <u>similar</u> triangles are <u>proportional.</u>
  • <u>Transitive</u> property of <em>equality</em>.
