question 6) B
Answer:
-44° F
Step-by-step explanation:
In order to get the temperature after the decrease, we need to subtract 16 from -28. You can write this as -28 - 16, or (-28) + (-16) because subtracting a positive number from a negative number is just like adding two negative numbers.
Furthermore, adding negative numbers is just like adding positive numbers, but just with a negative sign. So, (-28) + (-16) = <u>-44</u>.
When you rotate the image using the 90 degrees rule, the end points of the image will be (-1, 1) and (-3, 3). The rules for the other common degree rotations are: For 180 degrees, the rule is (x, y) --------> (-x, -y) For 270 degrees, the rule is (x, y) --------> (y, -x)
Answer:
How many different lines pass through a 3x3-point grid if a line only needs two points?
Step-by-step explanation:
The answer being (93)=9! 3! 6! =9⋅8⋅73⋅2⋅1=84 possible arrangements.
1/2 because 6/7 and 6/5 are over 1 and 3/4 is greater than 1/2
