Answer: True, False, False, False, False

Step-by-step explanation:

a) 5x - 7(x - 1)

5x - 7x + 7

-2x + 7 ⇒ a = -2, b = 7 One Solution

b) 3(x - 5) - 7

3x - 15 - 7

3x - 22 ⇒ a = 3, b = -22 One Solution

c) 2 - 7x + 3 + 4x

4x - 7x + 3 + 2

-3x + 5 ⇒ a = -3, b = 5 One Solution

d) -3(x - 3) - 1

-3x + 9 - 1

-3x + 8 ⇒ a = -3, b = 8 One Solution

e) -5x + 2 + 2x + 4

-5x + 2x + 2 + 4

-3x + 6 ⇒ a = -3, b = 6 One Solution

Which is one of the transformations applied to the graph of f(x) = x2 to change it into the graph of g(x) = 9x2 – 36x?

Alona [7]

Answer:

The answer to your question is the third option

Step-by-step explanation:

See the picture below

a) In the picture we observe that the parabola was narrowed not widened, so this option is incorrect.

b) From the picture, we conclude that the graph was shifted right 2 units, not four, so this option is incorrect.

c) From the picture, we observe that this option is the correct one.

d) We observe in the picture that this graph was not reflected so this option is incorrect.

PLEASE SOMEONE HELP ME WITH THESE QUESTIONS I'VE BEEN STUCK ON HERE FOR SO LONG

Neporo4naja [7]

Answer:

# means number

Step-by-step explanation:

Distance = Y-axis or output

Cost= X-axis or input

you do not need to add the brackets for the formula(BEDMAS), but it makes things clearer

For A -

the Y-intercept is where the first coordinate, or the # or the X-axis, is 0 (on the graph the y-intercept 0,4)

For B -

y = mx + b

m = slope

x = input or # on the X-axis

b = y-intercept

formula = (input x increase in the slope) + output for 0 or (distance x increase in cost) + output for 0

input(x axis) output(y axis)

0 5 ← output for 0

1 9

2 13

there is a +4 increase in the slope, the increase in the slope is an output #(in this case 9) - the previous output number (in this case 5)

formula = (input x increase in the slope) + output for 0 = distance

formula in use = (3 x 4) + 5 = 17

For C:

The dependent variable is the output or the cost because the input or the distance will determine the cost travelled. Eg. if I travel 9 miles it will cost $41. If the dependent variable is the cost then the independent variable is the distance

For D: (input x increase in the slope) + output for 0

(4.2 miles x $4) + 5

16.8 + 5 = $21.8; It will cost $21.8 to travel 4.2miles

For E: (distance x increase in cost) + output for 0

(? x 4) + 5 = 14

(14 - 5) = 9

9 ÷ 4 = 2.25miles; with 14 dollars I could travel 2.25 miles

(It is a bit confusing lol, but this is the way I understand it, if you can't understand it this way then use y = mx + b)
