Show that line passing through points (3,-2) and (-4,-2) is a horizontal line​

Mathematics
1 answer:
Ierofanga [76]3 years ago
3 0

Step-by-step explanation:

horizontal lines will have a gradient(m) of 0

so if m=0 , the line is horizontal

formula to find m:

m=y2-y1 / x2-x1

insert coordinates into formula

m =  \frac{ - 2 - ( - 2)}{ - 4 - 3}  \\  \\ m =  \frac{ - 2 + 2}{ - 7}  \\ m =  \frac{0}{ - 7}  \\ m = 0

As m=0 , therefore it is a horizonta line.

hope this helps..

Simplify the expression and rewrite in rational exponent form.
Dahasolnce [82]

Answer:

4 x^{\frac{11}{10}} \cdot y^{\frac{17}{3}}

Step-by-step explanation:

The given expression: 4 \sqrt[5]{x^{3}} \cdot y^{4} \cdot \sqrt{x} \cdot \sqrt[3]{y^{5}}

Step 1: Change radical to fractional exponent.

Formula for fractional exponent: \sqrt[n]{a}=a^{\frac{1}{n}}

The power to which the base is raised becomes the numerator and the root becomes the denominator.

\Rightarrow 4 x^{\frac{3}{5}} \cdot y^{4} \cdot x^{\frac{1}{2}} \cdot y^{\frac{5}{3}}  

Step 2: Apply law of exponent for a product a^{m} \times a^{n}=a^{m+n}  

Multiply powers with same base.

\Rightarrow 4 x^{\frac{3}{5}+\frac{1}{2}} \cdot y^{4+\frac{5}{8}}  

Take LCM for the fractions in the power.

\Rightarrow 4 x^{\frac{6}{10}+\frac{5}{10}} \cdot y^{\frac{12}{3}+\frac{5}{3}}  

\Rightarrow 4 x^{\frac{11}{10}} \cdot y^{\frac{17}{3}}

Hence the simplified form of 4 \sqrt[5]{x^{3}} \cdot y^{4} \cdot \sqrt{x} \cdot \sqrt[3]{y^{5}} \text { is } 4 x^{\frac{11}{10}} \cdot y^{\frac{17}{3}}.
