Answer:

y = 3x+6

Step-by-step explanation:

y=3x-2

This is in the form

y = mx+b where m is the slope and b is the y intercept

The slope is 3 so a line parallel also has a slope of 3 since parallel lines have the same slope.

Using slope intercept form

y = 3x+b

We have a point (2,11)

11 = 3*2+b

11 =6+b

11-6 = b

5 =b

The equation is

y = 3x+6

2) A

3) B

4) D

5)A

6) D

7)  A

8) C

9) D

Step-by-step explanation:

1) -5 (-2) -6= 4

2) 3 coins plus c coins = 3 + c

3) x-2 =16, x = 18

4) \frac{z}{-12} =-5. Clearing, z =  60

5) x =13,4

6) 14=t-4. Clearing t = 58

7) -30=j+50, clearing j=80

8) 2.8x=-9.24, clearing x=-3-3

9) 5.8= \frac{z}{2.2}. Clearing z=12.76

given an existing function: f(x)=0.5(x-2)2+3, what transformstiins would have to be made to result in g(x)=-2(x+3)2 -1?
eimsori [14]

Answer:

  • vertical scaling by a factor of -4
  • horizontal translation 5 units left
  • vertical translation 11 units up

Step-by-step explanation:

We notice that the multiplier of the squared term in f(x) is 0.5; in g(x), it is -2, so is a factor of -4 times that in f(x).

If we scale f(x) by a factor of -4, we get ...

  -4f(x) = -2(x -2)² -12

In order for the squared quantity to be x+3, we have to add 5 to the value that is squared in f(x). That is, x -2 must become x +3. We have to replace x with (x+5) to do that, so ...

  (x+5) -2 = x +3

The replacement of x with x+5 amounts to a translation of 5 units to the left.

We note that the added constant after our scaling changes from +3 to -12. Instead, we want it to be -1, so we must add 11 to the scaled function. That translates it upward by 11 units.

The attached graph shows the scaled and translated function g(x):

  g(x) = -4f(x +5) +11

PLEASE HELP!! Ill GIVE BRAINLIST IF RIGHT!! Refer to this table, which Francine, Geraldo, and Jennifer made during a bicycling t
kaheart [24]

Answer:

d = 4.5t

Step-by-step explanation:

Based on the table...

Francine covers:

9 miles in 2 hours

AND

18 miles in 4 hours

(You can use either one for this)

All you have to do is divide the \frac{miles}{hours}....

So, we can set up the fraction \frac{9 miles}{2 hours}

\frac{9}{2} =4.5 ...

So, knowing that 2 (time) · 4.5 = 9 (miles)...the answer would be

d(miles) = 4.5t (time)

So, the answer is d = 4.5t

Hope this helps!!!

The large rectangle shown represents one whole . Which division expression does the purple shaded area in the model represent
Hatshy [7]

Answer: The answer is (d)~\dfrac{1}{3}\div 4.


Step-by-step explanation:  Given in the question and the figure a large rectangle consisting of 12 squares of equal areas. We need to choose the right expression for the purple shaded area.

Considering the rectangle in the figure horizontally, there are 4 rows of 3 squares. So, in the last row, the fraction of  purple shaded square is

r_p=\dfrac{1}{3}.

And if consider the figure vertically, then there are 3 columns of 4 squares.

Therefore, the final fraction represented by the purple shaded area is

f_p=\dfrac{1}{3}\div4.

Thus, the correct option is  (d)~\dfrac{1}{3}\div 4.
