Which is an equation of a line that passes through the points (2, 6) and (-2,4)?

lyudmila [28]

Answer:

Equal the gradient of the given points & of some arbitrary point

Step-by-step explanation:

The gradient of the line = $\frac{6-4}{2-(-2)}=\frac{2}{4} =\frac{1}{2}$

Select some arbitrary point $p(x,y)$ on that line and rewrite the relationship for the gradient with either point (given) and then equal it to what we just calculated.

$\begin{aligned}\frac{y-6}{x-2} &= \frac{1}{2}\\y-6&= \frac{1}{2}(x-2)\\y&= \frac{1}{2}x+5\end{aligned}$

Are triangles DEF and LNM similar if DF = 8 and LM = 4?

Komok [63]

We Cannot conclude that triangles DEF and LNM are similar if DF = 8 and LM = 4.

Solution:

Given that for two triangle DEF and LNM, DE = 8 and LM = 4.

To say that two triangles are similar the provided information is not complete.

Two triangles DEF and LNM , will be similar if there corresponding sides are in ratio which means

$\frac{\mathrm{DE}}{\mathrm{LM}}=\frac{\mathrm{EF}}{\mathrm{NM}}=\frac{\mathrm{EF}}{\mathrm{NM}}$

But we have only information of $\frac{\mathrm{DE}}{\mathrm{LM}}=\frac{8}{4}=2$

But do not have any information regarding two remaining ratios that are $\frac{\mathrm{EF}}{\mathrm{NM}} \text { and } \frac{\mathrm{EF}}{\mathrm{NM}}$

Hence cannot conclude that triangles DEF and LNM similar if DF = 8 and LM = 4

Urgent! Please answer ALL of the following questions to receive brainliest answer! Use the picture attached to solve! Thank you!

1. The two angles add up to 180°.

2. You can create an equation because of this:
2x - 3 + 7x + 21 = 180
9x + 18 = 180
- 18
9x = 162
÷ 9
x = 18

3. <KMP is equal to <YMA because they are vertically opposite, so you can substitute in the value of x to find it.
(7 × 18) + 21
126 + 21 = 147
answer = 147°

4. The complement of an angle is the value that makes it add up to 90°, so first we need to find <KMA:
(2 × 18) - 3
36 - 3 = 33°
90 - 33 = 57
answer = 57°

I hope this helps!
