Alex

Answer:

Step-by-step explanation:

b) 1- scale factor from the first map to the second map:

$\frac{8}{6}$ = 1.33

2- landmark on the first map is a triangle with side lengths of 3 mm, 4 mm, and 5 mm.

Side lengths of the landmark on the second map

Divide the length by scale factor:

side lengths of 3 mm: $\frac{3}{1.33}$ = 2.25 mm

side lengths of 4 mm: $\frac{4}{1.33}$ = 3.007 mm

side lengths of 5 mm: $\frac{5}{1.33}$ = 3.75 mm

If x represents one of the equal sides of the triangle, then which equation can be used to solve the problem?

Maksim231197 [3]

X + 2(x + 4) = 32
3x + 8 = 32
3x = 24
x = 8

The lengths of the sides are 8, 12 and 12 (answer),

Is each line parallel, perpendicular, or neither parallel nor perpendicular to the line −3x+5y=−15? Drag and drop each choice in

nexus9112 [7]

The first line is perpendicular, the second line is not perpendicular and not parallel , the third line is parallel to the above line and the forth line not parallel or perpendicular to the line.

<h3>How can the slope of the line be calculate?</h3>

The slope of the line is been given as −3x+5y=−15

Then $y= \frac{3}{5x} -3$ , hence the slope is $\frac{3}{5}$
