Find the slope of the line that contains the points (1,-1) and (-2,8)

motikmotik

The formula for slope is (y-y1)/(x-x1).
1 = x
-1 = y
-2 = x2
8 = y2

You would plug those into the formula: (-1-(-2))/(-1-8) and that would equal to: 1/(-9).

$30( \frac{1}{2} x - 2) + 40( \frac{3}{4} y - 4) = \\$

$(30 \times \frac{1}{2} x) -( 30 \times 2 )+ (40 \times \frac{3}{4} y )- (40 \times 4 )= \\$

$15x - 60 + 30y - 160 = \\$

$15x + 30y - 220$

Are the triangles similar? If so, write a similarity statement for the triangles and explain how you know the triangles are simi

andrew-mc [135]

right-handThe triangles are similar if, the ratios of their sides are equal

$\frac{AE}{AC}=\frac{AW}{AL}$

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

On the left-hand side

$\frac{16}{12}=\frac{4}{3}$

and in the right-hand side, we have

$\frac{8}{6}=\frac{4}{3}$

The left-hand side equals the right-hand side; therefore, the triangles are similar.

Prove that if xy > 0, then either x > 0 and y > 0 or x < 0 and y < 0

Rufina [12.5K]

The rule of product states that:

$(+) \cdot (+) = (+)$
$(+) \cdot (-) = (-)$
$(-) \cdot (+) = (-)$
$(-) \cdot (-) = (+)$

So, a product is positive if and only if both factors have the same sign, and is negative if only if the factors have opposite sign.
