Answers
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.

1. Which of the following is the slope-intercept form of 6x + 2y = 28?
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
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

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.

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.
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 = XTherefore, 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
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)} .

what is the answer and steps to solve problem-2(b - 4) = 12
Answers
Answer:
b= -2
Step-by-step explanation:
First, you distribute.
-2(b-4) = 12
-2b + 8 = 12
Then, you combine like terms.
There are no like terms.
So, Next, you subtract 8 from each side.
-2b + 8 = 12
-2b - 8 = 12 - 8
-2b = 4
Finally, you divide each side by -2
-2b / -2
4 / -2
Answer: b = -2

therefore only positive x (and then renamed y) are possible for the reverse function
that is easy and quick.
y = x² + 2
y - 2 = x²
x = +sqrt(y - 2)
and after trading the variable names to a regular function definition we then have
y = +sqrt(x - 2)
