Answer:
undefined.
Step-by-step explanation:
-2-5/-3-(-3)
-7/0
Undefined
-13+9=-4
When you add a positive number to a negative number the answer will get closer to 0 and then progress up in positive numbers. In this case we are finding which of the numbers equals -4 when added to -13. Remember, if you add a negative to a negative you will get a negative.
-13+-17=-30 This is the wrong answer.
-13+-9=-21 This is the wrong answer.
-13+17=4 This is the wrong answer. (This is positive 4 we are trying to find -4)
-13+9=-4 This is the right answer
Therefore X=9
the formula to find the diagonal would be
a^2+b^2=c^2
3^2+4^2= 9+16=25
the square root of 25 is 5
5^2=25
so your diagonal is 5 ft
Later in the afternoon, the sun would most likely begin to set making quality sunlight pictures, but poor lighting for selfies.
I’m not extremely good at math but I think you need to make -x-y=1 into y=mx+b form and then solve your new equation!
