Answer:

b. (1.4y)

Step-by-step explanation:

When a variable has no number next to it, it is always going to be 1 multiplied by the variable. adding 1y and 0.4y would make 1.4y.

The graph of y = 3 over the sqaure root of x

mr_godi [17]

Answer:

$f(x) =\frac{3}{\sqrt{-x}}-2$

Observe the attached image

Step-by-step explanation:

The original function is:

$y =\frac{3}{\sqrt{x}}$

If we have a function g(x), then the graph of g(-x) will be equal to the graph of g(x) reflected on the y-axis.

In the same way, the graph of g(x)-2 is equal to the graph of g(x) displaced 2 units down

In this case $y = g(x)=\frac{3}{\sqrt{x}}$

Then

$g(-x) =\frac{3}{\sqrt{-x}}$

Finally

$f(x) =g(-x)-2 =\frac{3}{\sqrt{-x}}-2$

$f(x) =\frac{3}{\sqrt{-x}}-2$

The graph of f(x) is equal to the graph of $y =\frac{3}{\sqrt{x}}$ reflected on the axis-y and displaced 2 units downwards as seen in the attached image

Alice has just discovered base 10 cake! She is delighted with how powerful it is. One day, after nibbling on the cake, Alice rea

Romashka [77]

Answer:

5.38 ounces

Step-by-step explanation:

Given that :

Alice height = 1 mile

Distance of earth to moon = 239000 miles

Number of base 10 cakes required so they Alice's head just touches the moon ;

Using the relation :

Distance = height per ounce * 10^number of ounces

Height per ounce = 1 mile ;

Let number of ounces = n

Hence,

239000 = 1 * 10^n

239000 = 10^n

Take log of both sides

Log(239000) = n

5.3783979 = n

5.3784 = n

Hence, Alice should take 5.38 ounces of base 10 cakes

On a coordinate plane, is translated 3 units up and 3 units to the right to create Line p is drawn through P and and Line q is d

Mandarinka [93]

Answer:

Lines p and q are parallel

Step-by-step explanation:

1) Completing the question:

On a coordinate plane, is translated 3 units up and 3 units to the right to create ′′. Line p is drawn through and ’, and Line is drawn through and ’. Which statement about Lines and is true?

If PQ (x, y) according to that rule then P'Q' (x+3, y+3). So let's plot to answer the question. Setting numbers for,x and y.

3) As you can see below, since we add 3 units to the right and 3 units up then no x-coordinate must be the same, no y-coordinate must remain the same. In addition, p and q won't have the same intercept, neither x nor y.
