Answer:

-3x + 14

Step-by-step explanation:

Expand -3(x-5)

. -3 * x = -3x

. -3 * -5 = 15

So

. y+1 = -3x + 15

Subtract 1 from both sides so that y is the subject

. y = -3x + 14

Now you can juse replace y with f(x) since theyre basically the same thing

358 steps

Step-by-step explanation:

We can work with the exponents to simplify our expression, and we will get:

[tex]\sqrt[n]{x^{3n}} = x^3[/tex]

Remember that a root of degree n is equivalent to an exponent of 1/n.

This means that we can rewrite a root of degree n as:

[tex]\sqrt[n]{x} = x^{1/n}[/tex]

Then our expression:

[tex]\sqrt[n]{x^{3n}}[/tex]

Can be rewritten as follows.

[tex]\sqrt[n]{x^{3n}} = (x^{3n}})^{1/n}[/tex]

Now we have the exponent of an exponent, that means that we just need to take the product between the two exponents.

Now we can take the product of the exponents to get.

[tex]\sqrt[n]{x^{3n}} = (x^{3n}})^{1/n} = x^{3n*1/n} = x^3[/tex]

You can see that in the third step the exponents n and 1/n cancell eachother, so we end only with the exponent 3.

That is the expression simplified.

Answer:

a inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.

Step-by-step explanation:

hope it helps :)

Answer:

In Algebra, inequality is a Mathematical statement that shows the relation between two expressions using the inequality symbol. The expressions on both sides of an inequality sign are not equal. It means that the expression on the left-hand side should be greater than or less than the expression on the right-hand side or vice versa. If the relationship between two algebraic expressions is defined using the inequality symbols, then it is called literal inequalities.  If two real numbers or the algebraic expressions are related by the symbols “>”, “<”, “≥”, “≤”, then the relation is called an inequality.

Answer:

x = 7; y = 3

Step-by-step explanation:

I used the Trial and Error Method and found that x = 7 and y = 3

=> 7 + 3 = 10

=> 10 = 10. ✔

=> 7 - 3 = 4

=> 4 = 4. ✔

Therefore, x = 7 and y = 3

Answer:

y =5x

Step-by-step explanation:

[tex]y_{1}-y_{2} = m(x_{1} - x_{2} )[/tex]

(5 - 0) = m(1 - 0)

5 = m(1)

5 = m

[tex]y_{1}-y_{2} = m(x_{1} - x_{2} )[/tex]

y - 5 = 5(x - 1)

y - 5 = 5x - 5

y = 5x -5 + 5

y = 5x

Step-by-step explanation:

their are total 12 sandwiche rolls in a dozen so,

price of 12 sandwiche rolls are $1.50

so, cost of 1 sandwich roll = 1.50/12 = $0.125

now,

cost of 30 sandwich rolls = 30 × 0.125 = $3.75

therefore, option C is correct.
