Answer:

Part 1) The slope is m=5

Part 2) The slope is m=-2

Part 3) The slope is m=2

Step-by-step explanation:

Part 1) we know that

The equation of the line into slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have

y=5x+1

so

the slope is m=5

Part 2) we know that

The equation of the line in standard form is equal to

Ax+By=C

where

the slope is equal to m=-\frac{A}{B}

in this problem we have

2x+y=6

so

A=2,B=1,C=6

substitute

m=-\frac{2}{1}

m=-2

Part 3) we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

A(2,3)\ B(5,9)

Substitute the values

m=\frac{9-3}{5-2}

m=\frac{6}{3}

m=2

Sketch the figure: Two different isosceles triangles with perimeter 4a + b
Nikitich [7]

The two triangles with the given perimeter is attached .

Perimeter is the sum of all sides.

For the first triangle , sies are  2a,2a and b.

So the perimeter is

Perimeter = 2a+2a+b
\\
Perimeter = 4a+b

For the second triangle, sides are a,a, and 2a+b. Therefore perimeter is

Perimeter = a+ a + 2a+b
\\
Perimeter = 4a+b

So for both triangles, perimeter is

4a+b

Answer dis please- Thanks
hodyreva [135]

Answer:

Since we know that ABCD ~ EFGH, we have the ratios:

EF/AB = GH/CD

=> 0.4/1.2 = x/1.8

=> x = (1.8 . 0.4)/1.2 = 0.6

So x = 0.6
