describe the transformation g(x) = 2(х-4)^2 +2
Answer:
Step-by-step explanation:
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
horizontal shift- right four units
vertical shift- up 2 units
Reflection about the x-axis: None
Reflection about the y-axis: None
Vertical Compression or Stretch: Stretched
Stefan is making meringue with egg whites and sugar. He uses 505050 grams of sugar for every egg white.
If Stefan uses 101010 egg whites, how many grams of sugar does he use?
grams
Answer:
Stefan uses 500 grams of sugar with 10 egg whites.
Step-by-step explanation:
Given that Stefan is using 50 grams of sugar with one egg white.
In order to find the quantity of sugar for more eggs, we have to multiply the amount of sugar for one egg with number of eggs.
Now,
We have to find the quantity of sugar for 10 eggs.
[tex]Sugar\ for\ 10\ eggs = 10*50 = 500[/tex]
Hence,
Stefan uses 500 grams of sugar with 10 egg whites.
Answer:
500 grams

The sum of the ages of two friends is 13 years and the product
of their ages is 42. Find their ages.
Step-by-step explanation:
The sum of ages of two friends is 13 years.
The product of their ages is 42.
Let the age of 1st friend and 2nd friend is x, y respectively.
1 st condition= The sum of ages of two friends is 13 yrs.
i.e x+y = 13........ (I)
2nd condition= The product of their ages is 42.
i.e X*y = 42........(ii)
From equation (I)
X+y = 13
or, X = 13-y........ (iii)
Putting the equation (iii) in equation (ii).
X*y= 42
(13-y) * y = 42
13y - y^2 = 42
[tex] {y}^{2} - 13y + 42 = 0[/tex]
[tex] {y}^{2} - (7 + 6)y + 42= 0[/tex]
[tex] {y}^{2} - 7y - 6y + 42 = 0[/tex]
[tex]y(y - 7) - 6(y - 7) = 0[/tex]
[tex](y - 6) (y - 7) = 0[/tex]
Either; y-6 = 0
y = 6
Or;
y-7=0
y = 7
Keeping the value of y as "7" in equation (ii)
x*y = 42
7x = 42
X = 42/7
Therefore, the value of X is 6.
Therefore, either 1st friend is 6 years and 2nd is 7 years.

Answer:
100.375Step-by-step explanation:
so 110
110/100=1.1
*15
16.5
16.5 dollar coupon
ok then sales tax
1.1*6.25
6.875
sales tax is 6.875
110-16.5
93.5
93.5+sales tax 6.875
100.375
final price 100.375

On Monday, Sean bought 3 cookies and 5 cakes and spent $78.75. On Tuesday, Sean bought 8 cookies and 2 cakes and spent $40.
Find the price for one cookie and one cake.
Answer:
1 cookie = $1.25 1 cake = $15
Step-by-step explanation:
set up a system of equations:
let x = 1 cookie
let y = 1 cake
3x + 5y = 78.75
8x + 2y = 40
I multiplied the first equation by 2 to get: 6x + 10y = 157.50
I multiplied the second equation by -5 to get: -40x - 10y = -200.00
If you add both equations, the y-terms will be eliminated
-34x = -42.50
x = 1.25
Plug in 1.25 into equation to find value of y: 8(1.25) + 2y = 40
10 + 2y = 40
2y = 30
y = 15

3. As a fundraiser the school has a pie eating contest. Matt eats 2.75 pies in 300 seconds. b. Use place value, multiplication with powers of 10, or equivalent fractions to explain what is happening mathematically to the decimal points in the divisor and dividend before dividing.
Answer:
Using equivalent fractions, the time Matt takes to eat 1 pie is 1200/11 which is the same as [tex]109\frac{1}{11}[/tex] seconds
Step-by-step explanation:
The number of pies Matt eats = 2.75 pies
The time duration Matt eats 2.75 pies = 300 seconds
Mathematically, the time duration for Matt to eat one pie is given as follows;
The time to eat 2.75 pies = 300 seconds
Dividing both sides of the equation by 2.75 gives;
The time to eat 2.75/2.75 pie = 300/2.75 seconds
2.75/2.75 = 1, therefore, we have;
The time to eat 1 pie = 300/2.75 seconds
The equivalent fraction of 3000/2.75 = 1200/11
Therefore;
The time Matt takes to eat 1 pie = 1200/11 seconds

Question 16 of 20
For R(x) = 4x + 2 and g(x) = x2 - 6, find (f+g)(x).
A. 4x3 - 4
B. x2 + 4x - 4
O c. 4x2 - 16
O D. x2 + 4x+8
BMI
Answer:
(f + g)(x) = x² + 4x - 4 ⇒ B
Step-by-step explanation:
Let us solve the question
∵ f(x) = 4x + 4
∵ g(x) = x² - 6
→ We need to find (f + g)(x) which means f(x) + g(x)
∴ (f + g)(x) = f(x) + g(x)
∵ f(x) + g(x) = (4x + 2) + (x² - 6)
∴ f(x) + g(x) = 4x + 2 + x² - 6
→ Add the like terms
∵ f(x) + g(x) = 4x + x² + (2 - 6)
∴ f(x) + g(x) = 4x + x² + (-4)
→ Remember (+)(-) = (-)
∴ f(x) + g(x) = 4x + x² - 4
→ Arrange the terms from greatest power of x
∴ f(x) + g(x) = x² + 4x - 4
∴ (f + g)(x) = x² + 4x - 4

Write an equation of the line in slope-intercept form given the graph below.
(2.1)
(0, 2)
Answer:
y = -0.5x + 2
Step-by-step explanation:
m=(y2−y1)/(x2−x1)
m=(1-2)/(2-0)
m (slope) = -1/2 or -0.5
y = mx + b (we need b now, y-int)
1 = -0.5(2) + b
b - 1 = 1
b = 2
Now we have the slope (m) and the y-intercept (b), we can rewrite it as such:
y = -0.5x + 2
Hope this helped!
*Remember the equation of a line in slope-intercept form is y=mx+b. In this problem, we found the slope and y-intercept.
the ratio of the length and breadth of a rectangle is 5 is to 4and it's area is 180cm square find its length and breadth
Answer:
15cm and 12cm
Step-by-step explanation:
From the question,The ratio of the length and breadth of a rectangle is 5 to 4
We assume The Lenght of the field= 5x
The breadth = 4x
Area= (5x × 4x)= 180
20x^2= 180
X^2=
X= √9
X=3cm
The Lenght of the field= 5×3= 15cm
The breadth = 4×3=12cm

If I buy 5 plants from the garden centre at £3.00 a plant how much do the plants cost? If I have a £20 note how much change will I get?
Answer:
They will cost you £5.00 total
Step-by-step explanation:
If the plants each cost £3.00
You multiply the amount of plants, in this case is 5 by the price :-
5×3.00
= £15.00
You then subtract the total from the cash
15.00 - 20.00
= £5.00

Step-by-step explanation:
there's a property for Alternate Interior Angles
Answer:
Choice B
Step-by-step explanation:
The reason why < 3 is equal to < 6 is because they are alternate interior angles.
The first choice are supplementary angles they add up to 180 so they can't be equal.
The third one is false because we don't actually know the measurements of the angles but they both need to be 45° to add up to 90 since they are equal to each other.
The last one is also incorrect because they are vertical angles just like the third choice and they aren't on a line so they can't add up to 180.
