Which shows the pre-image of triangle X’Y’Z’ before the figure is rotated 90° about the origin

Xelga [282]

Answer:

From the figure shown the coordinates of W'X'Y'Z' are W'(2, 3), X'(6, 3), Y'(6, 4) and Z'(3, 5)

The coordinates of the pre-image that yeilded W'X'Y'Z' according to the rule (-x, -y) can be obtained by changing the signs of the coordinates of W'X'Y'Z'.

Thus, the coordinates of the pre-image that yeilded W'X'Y'Z' are W(-2, -3), X(-6, -3), Y(-6, -4) and Z(-3, -5).

Therefore, the correct graph is graph c.

Every 2 dozen cookies takes 1.5 teaspoons of cinnamon to make
She needs 13 dozen cookies

She needs 13 dozen cookies. So (13/2)x 1.5 teaspoons

$6.5 \times 1.5 = 9.75 \: teaspoons$

She needs 9.75 teaspoons and 3 teaspoons make a tablespoon

So..

$9.75 \div 3 = 3 r0.75= 3tbsp \: and \: 0.75tsp$

Given f(x) = x+2 and g(x) = x-4 solve for (fg)(x)

kirza4 [7]

Answer: f(g(x)) = x - 2

<u>Step-by-step explanation:</u>

f(x) = x + 2

g(x) = x - 4

f(g(x)) = f(x - 4) = (x - 4) + 2 <em>replaced x with x - 4</em>

= x - 2 <em>simplified</em>
