Solve. 5(y - 10) = -5 Answer: Submit Answer att
enyata [817]
Solving an equation<h2>Step 1</h2>

We divide both sides by 5 so we can eliminate the parenthesis:

\begin{gathered} 5(y-10)=-5 \\ \frac{5(y-10)}{5}=-\frac{5}{5} \\ y-10=-1 \end{gathered}<h2>Step 2</h2>

We rearrange the terms so the terms with the unkown variable y are on the left side and the other ones on the right side:

y - 10 = -1

↓ <em>adding 10 both sides</em>

y - 10 + 10 = -1 + 10

y + 0 = 9

y = 9

<h2>Answer: y = 9</h2>

Select the correct answer.<br> Rewrite the following expression.
kolezko [41]

The <em>algebraic</em> expression x^{10/3} is equivalent to the <em>algebraic</em> expression x^{3}\cdot \sqrt[3]{x}. Thus, the right choice is option D.

<h3>How to apply power and root properties to rewrite a given expression</h3>

In this question we must apply the following set of <em>algebraic</em> properties to simplify a given expression:

x^{m/n} = \sqrt[n]{x^{m}} = \left(\sqrt[n]{x}\right)^{m}   (1)

x^{m+n} = x^{m}\cdot x^{n}   (2)

x^{m\cdot n} = \left(x^{m}\right)^{n} = \left(x^{n}\right)^{m}   (3)

Where:

  • <em>m</em>, <em>n</em> - Exponents
  • <em>x</em> - Base

And also by apply the definition of power.

If we know that the given expression is x^{10/3}, then the equivalent expression is:

x^{10/3} = \sqrt[3]{x^{10}} = \sqrt[3]{x^{9}\cdot x} = \sqrt[3]{x^{9}}\cdot \sqrt[3]{x} = x^{3}\cdot \sqrt[3]{x}

The <em>algebraic</em> expression x^{10/3} is equivalent to the <em>algebraic</em> expression x^{3}\cdot \sqrt[3]{x}. Thus, the right choice is option D.

Which of these linear functions has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3? Se
valentinak56 [21]

Answer: the correct options are B, D and F

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

m = slope = rate of change

Looking at the equations given, the three that apply are

B) slope = 7

y intercept = 4

It has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3

D) y = 9x + 1

slope = 9

y intercept = 1

It has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3

F) y = 8x + 5

slope = 8

y intercept = 5

It has a greater rate of change than a linear function with a slope of 6 and a y–intercept of 3
