PLS HELP ASAP ILL GIVE BRAINLKEST PLS THANKS
fgiga [73]

Answer:

y = x + 64

Step-by-step explanation:

The total # of books she has read in the first row is 67, the difference between 67 and 3 is 64.

As you look at the other rows, you see as you subtract 64, you get the same number of additional books read.

Example: 67-64=3

77-64=13

87-64=23

97-64=33

x represents the number of additional books so if you add 64 to x you get the total number which is why the answer is the 3rd option

Could someone please help me with this problem
lina2011 [118]

Answer:

a = -1 , b = 4 , c = 3 , d = 1

Step-by-step explanation:

Given:

(-xy)^3 (xz) =ax^by^cz^d

The right hand side = (-xy)³ (xz) = (-1)³ x³ y³ x z = (-1) x⁴ y³ z

Comparing the right hand side with the left hand side

∴ a = -1

∴ b = 4

∴ c = 3

∴ d = 1

=======================================

The general rules of exponent:

1) \ a^m * a^n = a^{m+n}\\2) \ a^m / a^n = a^{m-n}\\3) (-1)^m = 1 \ (if \ m \ is \ +) and \ = \ -1 \ (if \ m \ is \ -)
