Answer:
(5.5, -3.5)
Step-by-step explanation:
As you can see in the figure, the fourth vertex is (5.5, -3.5)
If you observe carefully the vertex given, you will see that there are two vertex with same coordinates in x axis:
- (-1.2, -3.5),
-
(-1.2, 4.4),
And one vertex has other coordinate in x axis, it is: (5.5, 4.4)
To form a rectangle, you need a fourth vertex that will have same coordinate in x than (5.5, 4.4) and same coordinate in y axis as (-1.2, -3.5),
Then the fourth vertex coordinate is (5.5, -3.5)
There are 72 tokens with Riley and 63 tokens with Erik
<em><u>Solution:</u></em>
Riley and Erik have earned a total of 135 tokens to buy items in the school store
Total number of tokens = 135
The ratio of the number of tokens that Riley had to the number of tokens that Erik has is 8 to 7
Number of tokens with Riley : Number of tokens with Erik = 8 : 7
Let the number of tokens with Riley be 8x
Let the number of tokens with Erik be 7x
Since, Total number of tokens = 135
number of tokens with Riley + number of tokens with Erik = 135
8x + 7x = 135
15x = 135
x = 9
Therefore,
Number of tokens with Riley = 8x = 8(9) = 72
Number of tokens with Erik = 7x = 7(9) = 63
Thus there are 72 tokens with Riley and 63 tokens with Erik
Answer:
y= -3x+3
Step-by-step explanation:
First, write your current equation: y=-3x+b. Next, plug in the coordinate to your equation. It should look like this: 6= -3(-1)+b. Multiply -3 by -1 to get 3. This is what you should have: 6=3+b. Subtract 3 from both sides to get your y-intercept, 3. Go back to your original equation and plug in 3 to b. This is your final equation: y= -3x+3. So, the first answer is correct. Hope this helped!
Answer:
I think is it b.
