Answer:
A
Step-by-step explanation:
These triangles are first off congruent, because the only value that is changing, is the negative sign in front.
This negative sign means that the triangle is being rotated to a different quadrant of the graph, so the answer is A.
The probability of drawing at least one pair is 111/143.
Answer:
y=mx+b is the formula. So -8=-3x+5 would be the answer..
since (x,y) just substitute these numbers you have it into the formulas... Take y from (5,-8) and place it into y=mx+b. Next take the slope which is -3. And then since its a postive number we <em>add</em> are x from (x,y). -8=-3x+5. We also add x next to the slope (-3) becuase we are trying to solve for x. And we <em>always</em> put it next to the slope. Hope this helps!
Answer:
1/45
Step-by-step explanation:
make a probability of how many blues are in the bag
2/10.
simplify
1/5
Now that a marble is tooken away. there will be only one blue marble and 9 total marbles. make another probability.
1/9
now multiply the two probabilities.
1/5 × 1/9 = 1/45
