Multiply top and bottom by same number to give denominator of 72.
a x4
b x12
c x1
all = 48/72
d x18 =54/72
Answer:
x = 9
y =
Step-by-step explanation:
Since there is a 45° angle and a 90° angle, this is a isosceles triangle, therefore x = 9 and you can find y by pithagoras:
9² + 9² = y²
81 + 81 = y²
y =
Answer:
x = 4.54 , − 1.54
Step-by-step explanation:
Answer:
y - 9 = 8
y = 17
Step-by-step explanation:
Answer:
ok so you see the equation at the top... you are going to "plug in" the number in the "in" row to get the "out number
Step-by-step explanation:
example
in: 4
-2(-4)+1
8+1
9
so for the out row under -4 you would put 9
-2(-3)+1
6+1
7
so for the out row under 3 you would put 7
