Answer:

\textsf{A)} \quad y-7=-\dfrac{6}{11}(x+7)

Step-by-step explanation:

<u>Step 1:  Find the slope</u>

Define the points:

\textsf{let}\:(x_1,y_1)=(-7,7)

\textsf{let}\:(x_2,y_2)=(4,1)

Use the <u>slope formula</u> to find the slope:

\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{1-7}{4-(-7)}=-\dfrac{6}{11}

<u>Step 2:  Find the equation</u>

Use the found slope from step 1 together with one of the given points in the <u>point-slope form of a linear equation</u>:

\implies y-y_1=m(x-x_1)

\implies y-7=-\dfrac{6}{11}(x-(-7))

\implies y-7=-\dfrac{6}{11}(x+7)

<u>Conclusion</u>

Therefore, the equation of the line that passes through the points (-7, 7) and (4, 1) is:

y-7=-\dfrac{6}{11}(x+7)

In triangle ABC segment DE is parallel to the side AC . (The endpoints of segment DE lie on the sides AB and BC respectively). F
Sophie [7]

Answer:

The length of DE is 14 cm.

Step-by-step explanation:

Given in triangle ABC segment DE is parallel to the side AC . (The endpoints of segment DE lie on the sides AB and BC respectively). we have to find the length of DE.

Given lengths are AC=20cm, AB=17cm, and BD=11.9cm

In ΔBDE and ΔBAC

∠BDE=∠BAC       (∵Corresponding angles)

∠BED=∠BCA       (∵Corresponding angles)

By AA similarity rule, ΔBDE~ΔBAC

∴their corresponding sides are in proportion

⇒ \frac{BE}{BC}=\frac{BD}{BA}=\frac{DE}{AC}

⇒ \frac{BD}{BA}=\frac{DE}{AC}

⇒ \frac{11.9}{17}=\frac{DE}{20}

⇒ DE=\frac{20\times 11.9}{17}=14cm

Given that x +y=180, p +q =180, and p=x show that y =q
makvit [3.9K]
Showin that x=p the. The only way that y=q is because the others are the same say x=179 the y has to =1 and then p=179 so q has to equal =1
