To solve this, we’ll have to use inverse operations.
Since addition is the inverse to subtraction, we’ll add 20 to 620.
20 + 620 = 640
From there, since division is the inverse of multiplication, we’ll divide .75 by 640.
640/.75 = 853.33333 repeating. We can round this to 853.33, to round to the nearest hundredth.
Therefore, 853.33 would be your answer! You can check this by solving the equation forwards (853.33 x .75 = ~640, 640 - 20 = 620.)
Hope this helps! :)
Answer:
True
Step-by-step explanation:
Each time a spinner is spun, there is an equal chance that each result will occur, thus each of these spins are independent.
Answer:
Option 4
Step-by-step explanation:
-½ means it's -0.5, and then -0.4 then -3/10 = -0.3 and then -0.23, therefore it goes -½, -0.4, -3/10, then -0.23
Answer:
A. (1, -5), (2, -1), (-1, 7)
Step-by-step explanation:
Reflecting a function over the x-axis:
When a function is reflected over the x-axis, the x-value stays the same, while y changes the signal, so the transformation rule is:
To find the range:
We apply the transformation to the points in the domain. Thus:
Thus the correct answer is given by option a.
3x(5x+6)-8(1+8x)
15x^2+18x-8-64x
15x^2-46x-8 is your final answer
