Answer:

I think it's 3/4

Step-by-step explanation:

$y = k \times x + n$

On picture we can see that n=-1 and we also use

(x, y) = (-4,-4) and if we put that in function :

$- 4 = - 4 \times k - 1 \\ - 4k = - 3 \\ k= \frac{3}{4}$

Answer:

Area = 97.4 cm²

Step-by-step explanation:

a = 15 cm

$Area = \frac{ \sqrt 3}{4} a^2\\$

$=\frac{\sqrt 3}{ 4 } \times 15^2\\\\=\frac{\sqrt 3}{ 4 } \times 225\\\\= 97.4 \ cm^2$

What is the midpoint of QR. Q(2,4) and R(-3,9)

Eduardwww [97]

Answer:

The answer is

$( - \frac{1}{2} \: , \: \frac{13}{2}) \\$

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

$M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )\\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

Q(2,4) and R(-3,9)

The midpoint is

$M = ( \frac{2 - 3}{2} \: , \: \frac{9 + 4}{2} ) \\$

We have the final answer as

$( - \frac{1}{2} \: , \: \frac{13}{2}) \\$

Hope this helps you

$\huge \mathfrak \blue{Solution \: - }$

The formula for area of triangle is -

$\frac{1}{2} \times base \times height$

________________________________

So, the area of first triangle =

$\frac{1}{2} \times base \: \times height$

$\frac{1}{2} \times 4 \times 3$

$= \pink{6 \: units}$

________________________________

Area of second triangle =

$\frac{1}{2 } \times base \times height$

$\frac{1}{2} \times 4 \times 6$

$= \pink {12 \: units}$

________________________________

Area of second triangle - Area of first triangle

$= 12 - 6$

$= 6$

$\sf \underline\purple{The \: area \: increases \: by \: 6 \: square \: units.}$
