The graph of the function is f(x)= x2 − 4x + 6 . What is its axis of symmetry?

lianna [129]

To find the axis of symmetry you must first find the vertex of the parabola. The formula for vertex is -b/2a. So the vertex has a "x" coordinate at 4/2 or 2. so the axis of symmetry is the vertical line x = 2

Select the correct days. Gina tracks the low temperatures for a city over six days. Identify the days colder than -1.75°F.

Answer:

$Monday = -2.5F$

$Tuesday = -1.9F$

Step-by-step explanation:

Given

See attachment

Required

Days colder than -1.75°F

From the attachment, we have:

$Monday = -2.5F$

$Tuesday = -1.9F$

$Wednesday = 0F$

$Thursday = -1.5F$

$Friday = 0.5F$

Days with temperature less than -1.75°F are colder.

-2.5 and -1.9 are less than -1.75

So, we have:

$Monday = -2.5F$

$Tuesday = -1.9F$

DO,-2(x, y)(3, 5). The point (x, y) is (1, 3) (-3/2, -5/2) (-6, -10)

valina [46]

Answer: -6, -10.

The question is asking you to make the coordinates negative and then multiply the negative numbers by 2, thus, -6, -10.

Step-by-step explanation:

Hey there!

Given;

${2}^{4x - 1} =32$

${2}^{4x} . {2}^{ - 1} = {2}^{5}$

${2}^{4x} . \frac{1}{2} = {2}^{5}$

${2}^{4x} = {2}^{5} . {2}^{1}$

${2}^{4x} = {2}^{6}$

$4x = 6$

$x = \frac{6}{4}$

$x = \frac{3}{2}$

7.)

$\sqrt{x} - 3 = 7$

$\sqrt{x} = 7 + 3$

$( { \sqrt{x}) }^{2} = {(10)}^{2}$

X= 100

8.)

$( {x + 1)}^{2} = 81$

$(x + 1) = \sqrt{81}$

$x + 1 = \sqrt{ {9}^{2} }$

$x + 1 = 9$

$x = 9 - 1$

X=8

Hope it helps...
