Question 1:

Mathematics

Answer:

Q. 1: g(x) is translated 6 units down from f(x).

Q. 2: g(x) = 1.25 \times 10^{x}

Step-by-step explanation:

Question 1: Let y = f(x) = \frac{3}{4}x and y = g(x) = \frac{3}{4}x - 6 are two different functions.

Now, the value of y is decreased by 6 units in g(x) with respect to f(x).

Therefore, g(x) is translated 6 units down from f(x). (Answer)

Question 2: Let f(x) = 10^{x}, then transformation of f(x) by a vertical stretch with factor 1.25 means the y-value will be increases by 1.25 times for the same value of x.

Therefore, the transformed function will be g(x) = 1.25 \times 10^{x}. (Answer)

Find the midpoint of the segment with the given endpoints.<br> (-10,- 6) and (-3,7)
Marina CMI [18]

Step-by-step explanation:

in essence, these 2 points are the Hypotenuse of a right-angled triangle. the legs are the coordinate differences between the 2 points creating the 3rd point of that triangle at (-10, 7) : the x coordinate of one point, and the y coordinate of the other.

now, we are looking for the midpoint. this midpoint cuts the original line/hypotenuse in half creating a scaling factor of 1/2.

when we create now a similar triangle based on that "half- Hypotenuse", we need to use the same scaling factor also on the legs (the coordinate differences).

so, when we cut the coordinate differences also in half, we get the coordinates for the midpoint on the main line.

xm, ym are the coordinates of the midpoint.

xm = (x1 + x2)/2 = (-10-3)/2 = -13/2 = -6.5

ym = (y1 + y2)/2 = (-6+7)/2 = 1/2 = 0.5

so, the midpoint is (-6.5, 0.5)

Can someone help me with this problem please?
Tom [10]

Answer:

senior tickets sold: 12

child tickets sold:8

Step-by-step explanation:

Let

x= amount of senior tickets sold

y= amount of child tickets sold

For the first equation, it should look like:

200=14x+4y

For the second equation, it should look like:

92=7x+y

So this is a systems of equations problem. So I will use substitution as it is easier:

1.) Take one of the equations (in this case ill take 92=7x+y) and make one variable have a value, in this case ill isolate the y.

(-7x)92=7x+y(-7x)

y=92-7x

2.) Take the value of y and plug it into "y" into the other equation to solve "x"

200= 14x + 4(92-7x)\\200=14x+368-28x\\(-368)200=-14x+368(-368)\\(-\frac{1}{14})* -168=-14x*(-\frac{1}{14} )\\\\x=12

<u><em>(editor's note:instead of dividing it by 14, I multiply by 1/14 as it would look complicated in the equation solving steps)</em></u>

3.) Then plug the value of "x" to one of the equations to solve for "y" (which I'll use the 92=7x+y)

92=7(12)+y\\(-84)92=84+y(-84)\\y=8

Use the point-slope form to write an equation of a line through the given points.
Luden [163]

Answer:

y-2=1/3(x+3)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(4-2)/(3-(-3))

m=2/(3+3)

m=2/6

simplify

m=1/3

y-y1=m(x-x1)

y-2=1/3(x-(-3))

y-2=1/3(x+3)

Children play a form of hopscotch called jumby. the pattern for the game is as given below.
zaharov [31]

Answer:

7t^2 + 21t

Step-by-step explanation:

You have 7 tiles of each t by t+3.

One tile has an area of

t * (t+3) = t^2 + 3t

So in total the area is

7* (t^2 + 3t)

7t^2 + 21t
