What is 2x + 5 = 3x -33
33+ 5 = 3x-2x
38=3x-2x
38= 1x
38=x
Answers: 49, 1, 49
Those values go in the blanks from left to right
=====================================================
Explanation:
The rule we use is x^(-k) = 1/(x^k)
That means if we're evaluating something like 7^(-1), then it's the same as 1/(7^1) = 1/7 which explains how x = -1 leads to y = 1/7.
Similarly, 7^(-2) = 1/(7^2) = 1/49 is the y value when x = -2. So you'll type 49 into the first box to fill in that missing denominator.
Raising any nonzero value to the zeroth power leads to 1. That rule is x^0 = 1 where x can be anything you want but it can't be zero. Therefore 7^0 = 1 goes in the second box.
Lastly, 7^2 = 7*7 = 49 will go in the third box.
Answer:
32
Step-by-step explanation:
since the number of toothpicks are going up by 2 each time, the 15th figure will have 32 toothpicks
C. AC/AE = BD/BF
This is because AC with AE is equal to BD with BF since the lines a, b, c are parallel to each other.
Just do 7 x 5 = 35.............
