Answer:
f(x)=a(x - h)2 + k
Much like a linear function, k works like b in the slope-intercept formula. Like where add or subtract b would determine where the line crosses, in the linear, k determines the vertex of the parabola. If you're going to go up 2, then you need to add 2.
The h determines the movement horizontally. what you put in h determines if it moves left or right. To adjust this, you need to find the number to make the parentheses equal 0 when x equals -2 (because moving the vertex point to the left means subtraction/negatives):
x - h = 0
-2 - h = 0
-h = 2
h = -2
So the function ends up looking like:
f(x)=a(x - (-2))2 + 2
Subtracting a negative cancels the signs out to make a positive:
f(x)=a(x + 2)2 + 2
Step-by-step explanation:
The translated value of the function is h ( x ) = ( x + 4 )² - 7
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.
If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)
Right shift by c units: y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y = k × f(x)
Horizontal stretch by a factor k: y = f(x/k)
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x²
we can obtain the function h(x) by first translating it 4 units to the left, which gives us f(x + 4), and then translating it 7 units down, which gives us f(x + 4) - 7. Therefore, the function h(x) can be written as:
h(x) = f(x + 4) - 7
To write this in vertex form, we need to complete the square. First, we have:
h(x) = f(x + 4) - 7
h(x) = (x + 4)² - 7
This is the vertex form of the equation for h(x). The vertex of the parabola is at the point (-4, -7), which is obtained by setting x + 4 = 0 in the equation above.
The value of the vertex is -7, which is obtained by subtracting 7 from the squared term.
Therefore, the vertex form of the equation for h(x) is:
h ( x ) = ( x + 4 )² - 7
Hence , the transformed function is h ( x ) = ( x + 4 )² - 7

Can someone please help me find the area of the figure.
Answer:
45.4
Step-by-step explanation:
→ Area of the polygon = Area of Square + Area of semi-circle
Area of square :
→ Area of square = Side × Side
→ Area of square = 6 m × 6 m
→ Area of square = 36 m [tex] \sf ^2[/tex]
Area of semi-circle :
→ Area of semi-circle = [tex] \sf \dfrac{Area \: of \: circle}{2} [/tex]
→ Area of semi-circle = [tex] \sf \dfrac{\pi r^2}{2} [/tex]
→ Area of semi-circle = [tex] \sf \dfrac{\pi r^2}{2} [/tex]
→ Area of semi-circle = [tex] \sf \dfrac{3.14 \times (3)^2}{2} [/tex]
→ Area of semi-circle = [tex] \sf \dfrac{3.14 \times 3 \times 3}{2} [/tex]
→ Area of semi-circle = [tex] \sf \dfrac{28.26}{2} [/tex]
→ Area of semi-circle = 14.13 m[tex] \sf ^2[/tex]
⇒ Area of shape = ( 36 + 14.13 ) m[tex] \sf ^2[/tex]
⇒ Area of shape = 50.13 m[tex] \sf ^2[/tex]
Therefore,
Area of the shape is 50.13 m[tex] \sf ^2[/tex].Write an algebraic expression that is the quotient of a variable term and a constant.

Answer:
(47xy)/(6√3)
Step-by-step explanation:
A variable term is one that contains one or more variables, possibly with a coefficient. We can use 47xy as our variable term.
A constant is some number, or a representative of a particular number. π and e and Ф are representative of irrational constants. Of course, any number is also a constant. We can use 6√3 as our constant.
A quotient is formed when a first value is divided by a second value.
Here is the quotient of our variable term and our constant:
[tex]\dfrac{47xy}{6\sqrt{3}}[/tex]
An artist mixes paint to make new colors.
She uses 1/3 cup of red paint and 1/3 cup of yellow paint to make a batch of orange paint.
If the artist has 2 cups of red paint available and 3 cups of yellow paint available, how many batches of orange paint can she make?
Enter your answer in the box.
Answer:
6 batches of orange paint can be made.
Step-by-step explanation:
2 cups of red paint can go to 6 cups of 1/3 a batch of red paint, and 3 cups of yellow paint can go to 9 cups of 1/3 a batch of yellow paint.
She then combines 6 cups of 1/3 cups of red paint with 6 cups of 1/3 cups of yellow paint. The reason it is not 9 is that she doesn't have 3 extra 1/3 cups of red paint.
6 batches of orange paint can be made, with 3 extra 1/3 cups of yellow paint.

The formula for finding the volume of a rectangular prism is V = Bh. A rectangular prism with dimensions _________ will have a volume of 150 cubic units.
Answer: 10 * 5 * 3
Step-by-step explanation:
We want to find a base and a height that will multiply together to equal 150 [tex]units^{3}[/tex].
One solution is a [tex]B = 50 units^{3}[/tex] and [tex]h = 3 units^{3}[/tex].
Thus we need a length and width of the base that will multiply together to equal 50 [tex]units^{2}[/tex]. One solution is 10 units * 5 units.
Putting this all together, we have a solution of 10 units * 5 units * 3 units, which will have volume of 150 cubic units.

Lily and Mackenzie collected some stamps. If Lily gave 4 stamps to Mackenzie, Mackenzie would have twice as many stamps as Lily. If Mackenzie gave 4 stamps to Lily, they would have the same number of stamps. How many stamps did each girl have?
GIVING BRAINLIEST. PLS HELP. SHOW UR WORK TOO
Answer: hope this helps ♡
Lily had 16 stamps and Mackenzie had 20 stamps.
Step-by-step explanation:
Lily gives 4 stamps to Mackenzie
(Mackenzie) m + 4 = 2(L - 4) (Lily)
Solve for Lily:
m + 4 = 2L - 8
m + 4 + 8 = 2L
(m + 12) ÷ 2 = 2L ÷ 2
(m + 12) ÷ 2 = L
L = (m + 12) ÷ 2 (we will substitute this value for L in the second equation)
Mackenzie gives 4 stamps to Lily
(Mackenzie) m - 4 = L + 4 (Lily)
m - 4 = ((m + 12) ÷ 2) + 4
m × 2 - 4 = ((m + 12) ÷ 2 × 2) + 4
2m - 4 + 4 = (m + 12) + 4 + 4
2m - m = (m - m + 12) + 8
m = 12 + 8
m = 20 (we will substitute this value of m in the next equation)
L = (m + 12) ÷ 2
L = (20 + 12) ÷ 2
L = 32 ÷ 2
L = 16
