Answer:
tenths
Step-by-step explanation:
Suppose a number is given in the form ABC.ZYX
The place values would be:
C is ones
B is tens
A is hundreds
Z is tenths
Y is hundredths
X is thousandths
Looking at the number 502.78, we see that "7" is the first right place after decimal, which is same as "Z", which is tenths.
Hence 7's place value is tenths
(6y - 11)(6y + 11) = ay
² - b |use (a - b)(a + b) = a² - b²
(6y)² - 11² =ay² - b
36y² - 121 = ay² - b |add b to both sides
ay² = 36y² - 121 + b |divide both sides by y² ≠ 0
a = (36y² - 121 + b)/y²
Answer:
-1
Step-by-step explanation:
We need two points to use the slope formula
(0,2) and (2,0) are points on the line
m= ( y2-y1)/(x2-x1)
= (0-2)/(2-0)
= -2/2
=-1

Answer:
She didn't put the sign's in the proper place, it should be ( x + 3 ) ( x - 7 )
Step-by-step explanation:
( x - 3 ) ( x + 7 ) = x² + 7x - 3x - 21 = x² + 4x - 21
( x + 3 ) ( x - 7 ) = x² - 7x + 3x - 21 = x² - 4x - 21
