Simplify using the identity −2 /7 x 1/5 + 1/3 - 4/5 x - 2/7
Answer:
1/3 + 6/35
Step-by-step explanation:
We are given;
−2/7 × 1/5 + 1/3 - 4/5 × -2/7
Using the rule of bodmas, we will group them and solve with multiplication being the first operation.
1/3 - (4/5 × -2/7) + (−2/7 × 1/5)
Factorization of first and second bracket gives;
1/3 + 2/7(4/5) + 2/7(-1/5)
Factorizing again gives;
1/3 + 2/7(4/5 - 1/5)
>> 1/3 + 2/7(3/5)
>> 1/3 + 6/35

XOC = 60
A scientist is growing two species of bacteria. She defines a variable t that represents the number of days after the growth begins. The number of bacteria after t days is defined by: Species A: y=1000∙2^(t/3)
Species B: y=1000∙2^3t
(a) how many bacteria does each species start out with?
Number of bacteria each species start out with for the given exponential growth function is equals to 1000.
What is exponential growth function?

For Species B : [tex]y=1000 (2^{3t} )[/tex]
't' represents the number of days after the growth begins
a. For the given condition of the exponential growth function ,
t = 0 when species start out with
For species A
[tex]y=1000 (2^{\frac{0}{3} } )[/tex]
⇒ [tex]y=1000[/tex]
For species B
[tex]y=1000 (2^{3(0) } )[/tex]

If f(x) is parallel to the line y= 3/4 x + 2/5 which function could be f(x)
Answer:
If f(x) is parallel to the line y=3/4x+b ,it would have to have the same slope.
In this equation:
y=mx+b
m= is the slope of the line.
A line parallel to the line y=3/4x +2/5 must have the same slope; that it is to say, the slope would be m=3/4
Examples:
y=3/4 x+ 50000
y=3/4 x -51/36
y=3/4 x -√2
These functions could be parallels to the line y=3/4 x +2/5
Answer:
see below.
Step-by-step explanation:
The key to this question is the factor 3/4. So anything that is going to make the coefficient in front of x = to 3/4 is a possible answer.
y = 3/4x + b where b is anything but 2/5 is one answer. Disguised but still likely is
4y = 3x + b Where you could divide everything by 4
y = 3/4x + b/4
Even something like
-4y = - 3x + b is possible because when you divide by -4, you get
y = -3x/-4 + b/-4
y = 3x/4 - b/4
The graph of g(x) is a reflection and translation of f (x) = RootIndex 3 StartRoot x EndRoot.
On a coordinate plane, a cube root function goes through (0, 1), has an inflection point at (1, 0), and goes through (2, negative 1).
Which equation represents g(x)?
g (x) = RootIndex 3 StartRoot x + 1 EndRoot
g (x) = RootIndex 3 StartRoot x minus 1 EndRoot
g (x) = Negative RootIndex 3 StartRoot x + 1 EndRoot
g (x) = Negative RootIndex 3 StartRoot x minus 1 EndRoot
Transformation involves changing the form of a function.
The equation that represents g(x) is (c) [tex]g(x) =-\sqrt[3]{x+1}[/tex]
Function f(x) is given as:
[tex]f(x) =\sqrt[3]{x}[/tex]
First f(x) is reflected across the x-axis.The rule of this transformation (i.e. reflection) is:
[tex](x,y) \to (x,-y)[/tex]
So, we have:
[tex]f'(x) = -f(x)[/tex]
This gives
[tex]f'(x) =-\sqrt[3]{x}[/tex]
Next, f'(x) is translated 1 unit leftThe rule of this transformation (i.e. translation) is:
[tex](x,y) \to (x+1,y)[/tex]
So, we have:
[tex]g(x) = f'(x+1)[/tex]
This gives
[tex]g(x) =-\sqrt[3]{x+1}[/tex]
Hence, the equation that represents g(x) is (c)

Construct a 135° Angle
Now, provide the step - by - step instructions that you devised to create your own construction.
*WILL GIVE BRAINLIEST*
Answer: This would be how I would do it, so the answer might vary from what the teacher wants.
A 135 degree angle is a 90 degree plus 45 degree. So I would first draw a straight line, then divide the line into two 90 degree angles with a perpendicular bisector. Then I would draw a line dividing one of those 90 degree angles into two 45 degree angles. Now I would erase the middle line and now you have a 135 degree angle hint 90 + 45.

X= kilometers by bike
Y= kilometers by bus
How many kilometers did they travel by bike?
Answer:
430 km
Step-by-step explanation:
If they traveled 350 km by bus and biked 80 km more than they were bused, then,
Traveled by bus, Y = 350 km
Traveled by bike, X = 350 + 80 = 430 km

Step-by-step explanation:
A bag contains 10 red marbles, 7 blue marbles, and 3 green marbles. You randomly select a marble from the bag, record the color, and then put that marble back in the bag. If you were to do this 200 times, how many times would you expect to pull out a blue marble?
Answer:
70
Step-by-step explanation:
We have 7 blue marbles, and 20 total marbles. As a result, if we randomly chose one marble from the bag, the probability would be (number of favorable outcomes)/(number of total outcomes) = 7/20.
This means that for each 20 trials, we would expect to pull out a blue marble 7 times, as the probability does not change over time (because we put the marbles back, there are the same amount of each marble). Over 200 trials, we can simply make it out of 200 instead of 20. We can thus multiply 7/20 by 10/10 (10/10 is equal to 1, keeping the proportions equal) to get 70/200, so we can expect 70 blue marbles out of 200.

Maggie used the commutative property to write StartFraction 4 Over 5 EndFraction + 6.9 y minus 8 as the equivalent expression 6.9 y + 8 minus StartFraction 4 Over 5 EndFraction. Did Maggie apply the commutative property correctly? Why or why not?
Answer:
Maggie did not apply the law correctly
Step-by-step explanation:
Given 3 numbers A, B and C, for a commutative property
(A+B)+C = C+(A+B)
This shows that the remains the same no matter what values comes first
For the given expression
4/5+6.9y-8 = 6.9y+8-4.5
The values are not commutative because of the presence of negative sign. For the expression to be commutative, they must be equal no matter the way it is arranged and the sign must be positive all through for both sides. Hence Maggie did not apply the law correctly
