You can easily do just one step to get the value of x.
x + 9 =24 subtract 9 from both sides
x + 9 - 9 = 24 - 9
Simplify:
x = 15I hope I helped
you.
Y = x^2 - 6y + 8
y = (x - 3)^2 - 9 + 8
y = (x -3 )^2 - 1
vertex is at ( 3, -1)
Answer:
19.
h=0, the result is 1000×2⁰ = 1000
this is the population of bacteria the excitement started with at the very beginning.
h=-3, the result is 1000×2-³ = 1000/(2³) = 1000/8 = 125
this is a calculation 3 hours backwards from the very start of the experiment, saying that if we started the experiment 3 hours earlier, this would have had to be the starting population of the bacteria so we would arrive at the same amount of population at any given time (value of h).
20.
D 25x⁶
Step-by-step explanation:
for 19 there is not more explanation. it is all ashtray in the answer.
for 20 we see that we are dealing with a square, so ask 4 sides have the same length.
one side is 5x³.
the area of a square is simply side².
so, here (5x³)² = 25x⁶
Answer:
A and B only
Step-by-step explanation:
The table has x=10 that maps on to y=5 and y=-5.
This disqualifies the table for being a function.
The ordered pairs has no x-value repeating.
The graph of y=x² +10 is a vertical parabola that passes the vertical line test, hence it is also a function.
For a relation to be a function, no x-value must repeat; this means its graph must pass the vertical line test
