Answer:

We validate that the formula to determine the translation of the point to its image will be:

A (x, y) → A' (x+4, y-1)

Step-by-step explanation:

Given

A (−1, 4)→ A' (3, 3)

Here:

We need to determine which translation operation brings the coordinates of the image A'(3, 3).

If we closely observe the coordinates of the image A' (3, 3), it is clear the image coordinates can be determined by adding 4 units to the x-coordinate and subtracting 1 unit to the y-coordinate.

Thue, the rule of the translation will be:

A(x, y) → A' (x+4, y-1)

Let us check whether this translation rule validates the image coordinates.

A (x, y) → A' (x+4, y-1)

Given that A(-1, 4), so

A (-1, 4) → A' (-1+4, 4-1) = A' (3, 3)

Therefore, we validate that the formula to determine the translation of the point to its image will be:

A (x, y) → A' (x+4, y-1)

y = 2/x

Answer: 7 - (-5)+12

Step-by-step explanation: best I can put it

(-5) - (-12) = 7 . Option b,c, and d are correct.

Subtraction is a mathematical operator which gives diffrence between two numbers.

Given expression is,  (-5) - (-12)

                                 = -5 +12

                                 = 7

Absolute difference between -5 and -12 is equal to 7.

And, absolute difference between -12 and -5 is equal to 7.    

Also,                          (-5) + 12 = 7  

Hence, expressions with value = 7 are correct.

Answer:

The values of [tex]x[/tex] and [tex]y[/tex] are 10 and 14, respectively.

Step-by-step explanation:

According to the figure, we notice that [tex]AB\equiv BC\equiv AC[/tex] and [tex]\angle A \equiv \angle B\equiv \angle C[/tex], concluding that such triangle is equilateral. Since the sum of internal angles within triangle is equal to 180º, then:

[tex]m \angle A = m \angle B = m \angle C = 60^{\circ}[/tex] (1)

If we know that [tex]m\angle A = 6\cdot x[/tex], then the value of [tex]x[/tex] is:

[tex]6\cdot x = 60^{\circ}[/tex]

[tex]x = 10[/tex]

If we know that [tex]AC = 14[/tex] and [tex]AB = y[/tex], then the value of [tex]y[/tex] is:

[tex]y = 14[/tex]

The values of [tex]x[/tex] and [tex]y[/tex] are 10 and 14, respectively.

Answer:

  A.  y = 2/3x - 2

Step-by-step explanation:

The line intersects the y-axis at -2, so eliminates choices B and D, which have y-intercepts of +3.

The line has a rise of 2 grid squares for a run of 3 grid squares, so has a slope of ...

  m = rise/run = 2/3 . . . . . eliminates choice C

The appropriate choice is the one with a slope of 2/3 and a y-intercept of -2:

Step-by-step explanation:

Cuando Héctor gastó en la entrada de cine una tercera parte del dinero con el que salió de casa, tenemos:

[tex] C = \frac{1}{3}x [/tex]    (1)

Cuando compró una bolsa de palomitas con la cuarta parte:

[tex] P = \frac{1}{4}x [/tex]    (2)                                  

Entonces al sobrarle 5 euros y relacionando las ecuaciones (1) y (2) con el monto inicial:

[tex] x - C - P = 5 [/tex]

[tex] x - \frac{1}{3}x - \frac{1}{4}x = 5 [/tex]

[tex] x = 12 [/tex]

Por lo tanto, Héctor salió de su casa con 12 euros.

Answer:

1. 5, 11, 18, 26, 35, 45

Step-by-step explanation:

5, 11, 18, 26,

The difference between 5 and 11 is 6.

The difference between 11 and 18 is 7.

The difference between 18 and 26 is 8.

As you can see their difference increases by 1, so the next difference would be 8 + 1 = 9.

26 + 9 = 35

And the next difference would be 9 + 1 = 10.

35 + 10 = 45

Answer:The rate of the slower hiker is 2.2 mph and the rate of the faster hiker is 5.5 mph

Explanation:

One hiker walks 3.3 mph faster than the other.

Suppose, the speed of the slower hiker is  mph.

So, the speed of the faster hiker will be:  

Both hikers are walking toward each other and meet in 10 hours.

We know that,  

So, the distance walked by the slower hiker in 10 hours  miles and the distance walked by the faster hiker in 10 hours

miles.

Given that, they were 77 miles apart in the beginning. So the equation will be

Answer:

400 red boxes were sold

Step-by-step explanation:

Step 1: Our output value is 2000.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above,2000=100%.

Step 4: Similarly, x=40%.

Step 5: This results in a pair of simple equations:

2000=100%

x=40%(2)

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

2000/x = 100%/40%

Step 7: Again, the reciprocal of both sides gives

x/2000 = 40%/100%

x=800

Therefore, 40% of 2000 is 800

and to find 50% just divide by 2

Answer:

The answer would be y= -2x + 5

Step-by-step explanation:

If you look at your table you can see a pattern in the Y collum. It's being subtracted by two each time.

A line is a one-dimensional shape that is straight. The equation of the line is y=-2x+5.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is constant.

The slope of the line can be written as,

m = (3-1)/(1-2) = -2

Now, substituting the value of any point in the equation of the line, we will get,

y=-2x+c

1=-2(2)+

1=-4+c

c=5

Hence, the equation of the line is y=-2x+5.
