Answer:

Value of x=0

<u>Step-by-step explanation:</u>

Given:

     if y=5

To find:

   16 x-4 y=-20

Solve this system using substitution method and find the value of x

Solution:

The given equation:16 x-4 y=-20

And ify=5  

Substitute the value of y=5 in the above equation, we get

    16 x-4(5)=-20

    16 x-20=-20

    16 x=-20+20

    16 x=0

    x=0

Result:

Value of x=0 and (x, y)=(0,5)

Answer:

B: $2.50

Step-by-step explanation:

Step 1: form an equation

126 = 12(8 + x)

Step 2: isolate the x

126/12 = 8 + x

126/12 - 8 = x

Step 3: solve

10.5 - 8 = x

2.5 = x = raise per hour

In the function y=5x^2-2, what effect does the number 5 have on the graph, as compared to the graph of y=x^2?
allochka39001 [22]

General Idea:

The Rules for Transformations of Functions are given below:

If f(x) is the original function, a > 0 and c > 0; Then

f(x)+k \; \; shift \; f(x) \; UPWARD \; k \; units\\\\f(x)-k \; \; shift \; f(x) \; DOWNWARD \; k \; units\\\\f(x+h) \; \; shift \; f(x) \; LEFT \; h \; units\\\\f(x-h) \; \; shift \; f(x) \; RIGHT \; h \; units\\\\-f(x) \; \; REFLECT \; f(x) \; in \; the \; x-axis\\\\f(-x) \; REFLECT \; f(x) \; in \; the \; y-axis\\\\a \cdot f(x), \; a>1 \; STRETCH \; f(x) \; vertically \; by \; a \; factor \; of \; a\\\\a \cdot f(x), \; 0

f(ax), \; a>1 \; SHRINK \; f(x) \; horizontally \; by \; a \; factor \; of \;\frac{1}{a}  .\\\\f(ax), \; 0

Applying the concept:

In the function y=5x^2-2, the effect that the number 5 have on the graph, as compared to the graph of y=x^2 is given below:

C.it stretches the graph vertically by a factor of 5

This is the new update of the question
anzhelika [568]

Answer:

d

Step-by-step explanation:

If x represents the slant height, the graph would be a straight line.

If x represents the radius, the graph would be a parabola.

Looking at the answers, we're looking for x to be the slant height, so we're looking for a straight line.

We are looking for g(x). Answers a and b are wrong.

In g(x) r is fixed to 5 (this is given). So the slant height in the smallest possible cone would still be at least 5.

So the domain is x > 5.

d is your answer.

It takes layla 2/5 hour to swim 1/2 mile what is the unit rate of miles that layla can swim per hour
Mazyrski [523]

Good Morning!


Distance = rate x time


1/2 mile = R x 2/5 hour


1/2=2/5R


/2/5 /2/5


R=1/2 x 5/2


R=1 1/4


She can swim 1 1/4 per hour.


I hope this helps! :)
