Which function represents transforming ƒ(x) = 3x with a reflection over the x-axis and a vertical shift of 4 units?

Oxana [17]

Answer:

D. $h(x)=-3x+4$

Step-by-step explanation:

we are given

$f(x)=3x$

Firstly, it is reflected over x-axis

we know that for reflection about x-axis , we can replace y as -y

we get

$g(x)=-f(x)$

$g(x)=-3x$

now, it is vertical shift up by 4 units

so, we can add 4 to y-value

we get

$h(x)=g(x)+4$

$h(x)=-3x+4$

Simplify to create an equivalent expression (2j+1)9-7j

sveta [45]

Answer:

Simplifying

(2j + 1) * 9 + -7j = 0

Reorder the terms:

(1 + 2j) * 9 + -7j = 0

Reorder the terms for easier multiplication:

9(1 + 2j) + -7j = 0

(1 * 9 + 2j * 9) + -7j = 0

(9 + 18j) + -7j = 0

Combine like terms: 18j + -7j = 11j

9 + 11j = 0

Solving

9 + 11j = 0

Solving for variable 'j'.

Move all terms containing j to the left, all other terms to the right.

Add '-9' to each side of the equation.

9 + -9 + 11j = 0 + -9

Combine like terms: 9 + -9 = 0

0 + 11j = 0 + -9

11j = 0 + -9

Combine like terms: 0 + -9 = -9

11j = -9

Divide each side by '11'.

j = -0.8181818182

Simplifying

j = -0.8181818182

The equation of a circle is given below. 9 x^2+ (y - 7.5)^2 =9/49 What is its center?

My name is Ann [436]

Answer:

(0, 7.5)

Step-by-step explanation:

Compare the equation to the standard-form equation of a circle:

(x -h)^2 +(y -k)^2 = r^2 . . . . . . . center at (h, k); radius r

You will notice that ...

h = 0

k = 7.5

The center is (h, k) = (0, 7.5).

Identify the x- and y- intercepts of this equation. 5 − 4 = 20

Alinara [238K]

T he x and y intercepts of the equation: $5x-4y=20$ are : y-intercept is (0,-5) and x-intercept is (4,0)

So, Option D is correct.

Step-by-step explanation:

we need to identify the x and y intercepts of the equation: $5x-4y=20$

Finding x-intercept

For finding x-intercept put y=0

We are given the equation:

$5x-4y=20$

Solving:

$5x-4y=20\\5x-4(0)=20\\5x=20\\x=\frac{20}{5}\\x=4$

So, x-intercept is (4,0)

Finding y-intercept

For finding y-intercept put x=0

We are given the equation:

$5x-4y=20$

Solving:

$5x-4y=20\\5(0)-4y=20\\-4y=20\\y=\frac{20}{-4}\\y=-5$

So, y-intercept is (0,-5)

the x and y intercepts of the equation: $5x-4y=20$ are :y-intercept is (0,-5) and x-intercept is (4,0)

So, Option D is correct.
