Shape A can be transformed to shape B by a reflection in the x-axis followed by a translation (c/d). Find the value of c and the

value of d
Mathematics

Answer:

c = -6

d = -1

Step-by-step explanation:

Given

See attachment for grid

Required

Find c and d

From the attachment, we have:

a = (3,5) --- Point on A

a' = (-3,-6) --- Corresponding point on B

When A is reflected across the x-axis, the rule is:

(x,y) \to (x,-y)

So, we have:

(3,5) \to (3,-5)

Next, is to calculate the translation from (3,-5) to (-3,-6)

This is calculated using:

3 + c = -3

and

-5 + d = -6

So, we have:

3 + c = -3

c = -3-3

---- i.e. Shift by 6 units to the left

-5 + d = -6

d = 5 - 6

d = -1  --- i.e. Shift by 1 unit down

What steps would you use to plot (−3, −4, 0) in a 3-dimensional coordinate system?
eimsori [14]

Answer:

a. From the origin, move back 3 units and down 4 units

Step-by-step explanation:

Given:

The coordinates of a point in a 3-dimensional space is given as:

(-3, -4, 0)

The value of 'x' = -3

The value of 'y' = -4

The value of 'z' = 0

At the origin, the values of 'x', 'y', and 'z' are each equal to 0.

So, the coordinates of origin is (0, 0, 0). In order to reach the point (-3, -4, 0) from the point (0, 0, 0), we don't move along the z-axis as the 'z' value remains the same. We need to move along the 'x' and 'y' directions only.

Now, 'x' is equal to -3. Negative values of 'x' occur backwards from origin. So, we move back by 3 units. to reach the point (-3, 0).

Now, the value of 'y' is -4. Negative values of 'y' occur below the origin. So, we move down by 4 units to reach the point (-3, -4).

Therefore, the correct option is option (a)

A graph in 2 dimensional is shown in support of the answer.

Solve for x: 6x + 1 over 4 (4x + 8) > 12
sukhopar [10]

Answer:

A. x>\frac{10}{7}.

Step-by-step explanation:

We have been given an inequality 6x+\frac{1}{4}(4x+8)>12. We are asked to solve the given inequality for x.

Using distributive property, we will get:

6x+\frac{1}{4}*4x+\frac{1}{4}*8>12

6x+x+2>12

7x+2>12

Subtract 2 from both sides:

7x+2-2>12-2

7x>10

Divide both sides by 7:

\frac{7x}{7}>\frac{10}{7}

x>\frac{10}{7}

Therefore, option A is the correct choice.

Graph the line y+3=2(x-1) first identify the slope of the line
Mumz [18]
First you need to simplify the equation.

y + 3 = 2(x - 1)
y + 3 = 2x - 2

Then you need to put that into slope-intercept form (y = (slope)x + (y intercept))

y + 3 = 2x - 2
    -3           -3
y = 2x - 5

The slope is the coefficient of x, so 2 is the slope of the line.
