b=145 degrees (corresponding angles)
a+145= 180 (straight angles)
a = 180-145
a =35
Answer:
Step 5 is incorrect because a previous step is incorrect
Step-by-step explanation:
Step 1 correct
Step 2 correct
Step 3 correct
Step 4 incorrect: It must be
y² - 10y + 25 = 2x + 23
Step 5 incorrect because step 4 incorrect
Step 5 must be : 1/2(y - 5)² - 23/2 = x
Let's isolate x by moving the -1 to the left and the 3/2x to the right (direction chosen so that you don't get negative numbers):
Now multiply both sides by 2 and swap sides:
Answer:
the common denominator for the first question is 36
So 36, to get that you multiply 4 by 9 and 9 by 4.
you’d get
3 4/36 + 2 9/36
you’d get 5 13/36
That bai scaly answers both parts
8 4
14 7
6 3
That is the answer for the table
