Sorry, I can’t answer c. f(3)=  because when x is three from the x-axis on the graph, the line that meets 3 from the x-axis doesn’t show a whole number     y-coordinate on the graph :(

But I hope this helps and answers your question :)

Answer:

f(x)=8x^2-6

f(x) = a (x -h)2 + k

horizontal stretch by a factor of 2 -> 1/2 x

2 units up -> k = 2

reflection in y axis -> x value is negative

g(x) = 8*(1/2 x)2 - 6 + 2

g(x) = 2 x2 -4

Step-by-step explanation:

The vertex will be at g(x) = 2x² -4.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data. A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

Given that the graph of g is a horizontal stretch by a factor of 2 and a translation 2 units up, followed by a reflection in the y-axis of the graph of

f(3) = 8x² - 6.

f(x)=8x²-6

f(x) = a (x -h)2 + k

Horizontal stretch by a factor of 2 -> 1/2 x

2 units up -> k = 2

Reflection in y axis -> x value is negative.

g(x) = 8 x (1/2 x)² - 6 + 2

g(x) = 2x² -4

Therefore, the vertex will be at g(x) = 2x² -4.

Answer:

108

Step-by-step explanation:

Given that Joseph has 48 comic books.

As he sold 1/4 of his collection to his friend, so

The number of books, Josef sold = 1/4 x 48 = 12.

The number of remaining books, Josef has = 48 - 12 = 36.

As he brought twice the number of comic books as he has now, so,

the number of comic books, Josef brought = 2 x 36 = 72.

Now, total number of comic books, Josef has = 36 + 72 = 108.

Answer:

C.

-48x7y3

Step-by-step explanation:

The next answer on edge is also C. 9a8 + 24a4 + 16

The multiplication of -8x⁵y² and 6x²y will be -48x⁷y³ so option (C) will be correct.

Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.

Given the two terms,

-8x⁵y² and 6x²y

If we multiply

-8x⁵y² ×  6x²y = (-8)×6 × x⁵y² × x²y

⇒ - 48 × x⁵x² y²y¹

⇒ - 48 × x⁵⁺²y²⁺¹

⇒ - 48x⁷y³

Hence "The multiplication of -8x⁵y² and 6x²y will be -48x⁷y³".

Step one:

given data

we are told that the uber charges $1.25 per mile

and that Leo also gave a tip of $5

the function for the total charge is given as

y=mx+c

Step two:

we will use the notation m for the number of miles traveled

given that the total trip is $16.25

16.25=1.25m+5

solving for m we have

16.25-5=1.25m

11.25=1.25m

divide both sides by 1.25

m=11.25/1.25

m=9

So he travelled 9miles

10% of 900 is 90 (900÷10)

20% of 900 is 180 (90×2)     -     basically the 10% times 2

50% of 900 is 450 (900÷2)

450+180=630         -          the sum of the 20% and 50%

Answer:

Step-by-step explanation:

Triangle DEF is reflected over the y-axis, and then translated down 4 units and right 3 units.

(I searched it up)

The length of TU is 7 in.

Hence, option C is correct.

A quadrilateral is a shape with four sides, four vertices, and four angles that is only two dimensional. Convex and concave are the two main forms. Convex quadrilaterals can also be divided into a number of subgroups, including trapezoids, parallelograms, rectangles, rhombus, and squares.

Given that,

Quadrilateral ABCD is reflected over a line y

Hence preimage = ABCD and image = TURS

After reflection,

The new position of A = T

New position of B =U

New position of C = R and

New position of D = S

By transformation properties,

For reflection the scale factor is 1 and hence AB will have the same length as TU

Since,

AB = 7 inches,

Therefore,

TU = 7 inches.

The solution of the given equation [tex](4)^{3\sqrt{x} -2}[/tex] + 1 = 9 will be x = 1.08.

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.

Given is the following equation -

[tex](4)^{3\sqrt{x} -2}[/tex] + 1 = 9

The given equation is -

[tex](4)^{3\sqrt{x} -2}[/tex] + 1 = 9

[tex](4)^{3\sqrt{x} -2}[/tex]  = 8

Assume 3[tex]\sqrt{x}[/tex] = n. Then, we can write the equation as -

(4)ⁿ ⁻ ² = 8

(4)ⁿ ÷ (4)² = 8

(4)ⁿ x 1/(4)² = 8

(4)ⁿ = 8 x 16

(2)²ⁿ = (2)³ x (2)⁴

2n = 3 + 4

2n = 7

n = 7/2

3[tex]\sqrt{x}[/tex] = 7/2

[tex]\sqrt{x}[/tex] = 7/6

x = 1.08

Therefore, the solution of the given equation [tex](4)^{3\sqrt{x} -2}[/tex] + 1 = 9 will be

x = 1.08.
