Answer:

A. y = | x – 7 |

Step-by-step explanation:

y=|x-7| because in order to go to the right you have to subtract the amount from x

the answer is y=|x-7|

Step-by-step explanation:

we know that the general translation of some equation y=f(x) to the left or right direction by 'a' units is given by y=f(x+a) ; where if 'a' is negative then the translation is in the "right direction" and if 'a' is positive then the translation is in the "left direction".

so in the given question we have the equation y=|x| for it to be translated 7 units in the right the resulting equation is y=|x-7|.

Emma calculated the slope of the downhill hike to be -1/40 her work is shown below determine whether her calculation was correct
Monica [59]

The calculation is incorrect, because the slope is defined as

m_{AB} = \dfrac{y_A-y_B}{x_A-x_B}

So, Emma has inverted numerator and denominator: she has calculated the inverse of the slope.

The correct calculation would be

\dfrac{300-900}{180-165} = \dfrac{-600}{15} = -40

stephanie and jenny each improved their yards by planting rose bushes and geraniums. they bought their supplies from the same st
galina1969 [7]

Answer:

The cost of one rose is $11., and the cost of one geranium is $5.

Step-by-step explanation:

The cost of one rose bush and one geranium can be determined by the use of simultaneous equation. Let the cost of a rose bush be represented by x, and the cost of one geranium by y.

So that,

13x + y = 148 .............. 1

9x + 14 y = 169 ............... 2

From eqaution 1,

y = 148 - 13x ............... 3

substitute the value of y in equation 2

9x + 14(148 - 13x) = 169

9x + 2072 - 182x = 169

2072 - 169 = 182x - 9x

1903 = 173x

x = \frac{1903}{173}

  = 11

x = 11

substitute the value of x in equation 3

y = 148 - 13x

  = 148 - 13(11)

  = 148 - 143

y = 5

x = 11, y = 5

Thus, the cost of one rose is $11., and the cost of one geranium is $5.

Given the following roots build a polynomial function in standard form: -3 and +2
swat32

Answer:

  f(x) = x² +x -6

Step-by-step explanation:

The standard form will look like ...

  f(x) = x² +bx +c

where b is the opposite of the sum of the roots, and c is their product.

  f(x) = x² -(-3+2)x +(-3)(2)

  f(x) = x² +x -6

_____

<em>Additional comment</em>

In general, "standard form" is ax²+bx+c. In this case, the coefficient 'a' can be 1 since neither of the roots is expressed as a fraction. The sum of roots is (-b/a) and the product of roots is (c/a).
