the answer is b. y-5=1/2(x+3)^2

9514 1404 393

Answer:

  B.  y -5 = (1/2)(x +3)^2

Step-by-step explanation:

The parent function f(x) = x^2 has been shifted left 3 and up 5, and scaled vertically. The translation of the vertex to (h, k) can be modeled by ...

  y -k = a(x -h)^2

For (h, k) = (-3, 5), the form of the answer will be ...

  y -5 = a(x +3)^2

Only one answer choice has that form.

Additional comment

The coefficient 'a' will be positive when the parabola opens upward. This eliminates choices A and C. Choice D represents a translation of 3 units right and 5 units down—directions opposite of those shown on this graph.

Drag and drop each pair of lines into the correct category to indicate whether the pair of lines are parallel,

perpendicular, or neither.

7y = 3x + 1; 14x + y = 12

x - 2y = 10; y = x + 1

3x - 2y = -3; 3y = -2x + 3

1/8x + y = 5; y = -8%

y = 3x - 1; 12x - 4y = 12

A rectangular garden 30m by 20m consists of a lawn 28m by 18m surrounded by a path. The path is to be made of concrete to a depth of 8cm. Cal the vol of cement required in m3.
The cement is delivered in bags each holding 1cubic metre. Cal the cost if the cement costs #600 per bag and the labour charges are #2000. The company states that the cost will be approximately #70 per square metre. Is this correct?

Answers

1) The required volume of cement is 7.68 m3.

2) The costs will be $ 6,800, and the company's statement about approximate costs is correct.

1) Given that a rectangular garden 30m by 20m consists of a lawn 28m by 18m surrounded by a path, and the path is to be made of concrete to a depth of 8cm, to calculate the volume of cement required in m3 the following calculation must be performed :

8cm = 0.08mPath area x 0.08 = Volume((30 x 20) - (28 x 18)) x 0.08 = X(600 - 504) x 0.8 = X96 x 0.08 = X7.68 = X

Therefore, the required volume of cement is 7.68 m3.

2) Given that the cement is delivered in bags each holding 1 cubic meter, to calculate the cost if the cement costs $ 600 per bag and the labor charges are $ 2000 and determine, if the company states that the cost will be approximately $ 70 per square meter, if this statement is correct, the following calculations should be performed:

7.68 m3 = 8 bags (8 x 600) + 2000 = X 6800 = X

Therefore, the costs will be $ 6,800.

6800/96 = 70.833

Thus, the company's statement about approximate costs is correct.

Determine if Set of Points is a Function which set of ordered pairs represents a function: {(3,6),(3,1),(9,0),(2,2)}, {(2,−5),(−3,6),(−1,−8),(−3,−4)}, {(4,−7),(−2,−1),(−7,4),(9,−1)},{(3,8),(−2,−9),(1,4),(1,9)}

Answers

{(−2,−1),(−7,4),(9,−1)} Represents a function.

A function is a relation in which no two ordered pairs have the same input (or x-values) and different outputs (y-values).

Whenever you're trying to determine whether a given relation is a function, observe whether each first element (or input) correspond with EXACTLY ONE second element (or output).

Out of all the given options, the relation, {(−2,−1),(−7,4),(9,−1)} each x-coordinate corresponds exactly to one y-coordinate.

Therefore, the correct answer is {(−2,−1),(−7,4),(9,−1)} .

Find the equation of the line passing through the points (2, -1) and (-6, -5)

y = 2x - 5

y = -1/2 x

y = 1/2 x - 2

y = 1/2 x

Answers

Step 1: Find the slope

Point 1 = (2, -1)

Point 2 = (-6, -5)

m = (-5 - - 1) / (-6 - 2) = (-5 + 1) / (-6 - 2) = -4 / -8 = 1/2

m = 1/2

Step 2: Find the y-intercept

Slope-Intercept Form: y = mx + b

-m is the slope

-b is the y-intercept

---Plug in whichever point you want as well as the slope and solve for b

Point = (2, -1)

-1 = (1/2)(2) + b

-1 = 1 + b

b = -2

Step 3: Form the equation

Slope-Intercept Form: y = mx + b

m = 1/2

b = -2

y = 1/2x - 2

y=-3:2 – 14
y=-3x + 14
y= 3.c + 14
y= 3x - 14

Answers

Answer:

2nd option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

6x + 2y = 28 ( subtract 6x from both sides )

2y = - 6x + 28 ( divide the terms by 2 )

y = - 3x + 14 ← in slope- intercept form

Answer:

y= -3x + 14

Explanation:

6x + 2y=28

2y= -6x +28

Therefore, y= -3x +14

Identify the range of the image that has been reflected over the y-axis given the domain is

B. (-5, -3), (2, -2,), (7, 2)

C. (-5, 3), (2, 2), (7, -2)

D. (5, 3), (-2, 2), (7, 2)​

Answers

B is correct because when reflecting across the y-axis the x-coordinate, but the y-coordinate doesn’t

Range of the image whose domain is (5, -3), (-2, -2), (-7, 2) will be (-5, -3), (2, -2,), (7, 2) .

Given,

Domain of the image: (5, -3), (-2, -2), (-7, 2)

Now,

When the image is reflected over the y axis the coordinates of y axis changes but x coordinates remains the same.

So,

If domain of the image is (5, -3), (-2, -2), (-7, 2) then after reflection over y axis the range will be (-5, -3), (2, -2,), (7, 2) .

Therefore option B is correct.
