PLEASE HELP!!! CONVERT TO STANDARD FORM (y=ax^2+bx+c
f(x)=2(x-3)^2+7
Answer:
y = 2x^2 - 12x + 25Step-by-step explanation:
Given function
f(x)=2(x-3)^2+7Converting to standard form
y = 2(x - 3)^2 + 7y = 2(x^2 - 6x + 9) + 7y = 2x^2 - 12x + 18 + 7y = 2x^2 - 12x + 25How much tax would you pay on an item at 5% tax rate costing $75? (Round to the nearest cent)
Answer:
3.75
Step-by-step explanation:
Answer:
$3.75
Step-by-step explanation:
All you are going to do is multiply .05 or 5% by 75.
.05 * 75 = 3.75
(So now you are going to add 3.75 to $75 because the tax is 3.75)
75 + 3.75 = $78.75
(So you would pay $3.75 in tax)

Find the sum of -9X + 13 and -16x - 6
A.-25x +7
B. 25x -7
C.-25x-7
D.25x+7
Answer:
A. -25x + 7
Step-by-step explanation:
First, to answer this question, we will combine the two sides of the equation:
(-9x + 13) + (-16x - 6)
Now, we take away the parentheses and add like terms:
-9x + 13 + -16x - 6 =
-25x + 7
So, the answer would be A. -25x + 7

Are the lines y= -x-2 and 4x-4y =16 perpendicular? Explain
Answer:
Step-by-step explanation:
Annie bakes cookies and cupcakes in a ratio of 2 to 7 for her gift boxes. Her school needs 36 desserts to sell in a bake sale. How many cupcakes will she bake? How many cookies will she bake ?
Let's say cookies are 2x. If there are 2x cookies then there are 7x cupcakes. Now, 2x cookies + 7x cupcakes = 36 desserts.
9x = 36
So, x = 4
Now, remember that cookies = 2x. 2x = 2 times 4 = 8.
She will bake 8 cookies.

A photo 5 inches wide and 8 inches long is enlarged.
How wide is the new photo if it is (1)12 inches; (2)20 inches; (3)10 inches long?
Step-by-step explanation:
if the new photo is 12 inches long than the photo is enlarged
12/8=3/2
so the new photo is (3/2)*5 =15/2=7.5 inches wide.
Now,about the new photo 20 inches long it means that is enlarged 20/8=5/2 inches
so the new photo is wide 5*(5/2)=25/2=12,5 inches.
The photo 10 inches long is enlarged 10/8=5/4 inches.So the new photo is 5*(5/4)=25/4=6,25 inches wide.

18 = 3t (divide by 3)
6 = t
sub in to check
Answer:
t=6
Step-by-step explanation:
4.4=-13.6+3t [add -13.6 to both sides]
18=3t [divide 3 from 18]
t=6

What is the measure of \greenD{\angle x}∠xstart color #1fab54, angle, x, end color #1fab54?
Angles are not necessarily drawn to scale.Given the following:
Answer:
<x = 31°
Step-by-step explanation:
m<BCA = m<GCJ (vertical angles)
m<BCA = 59° (substitution)
Since line KL is perpendicular to line FG, the angle formed at point B is 90°.
Therefore, m<ABC = 90°
m<BAC + m<ABC + m<BCA = 180° (sum of triangle)
m<BAC + 90° + 59° = 180° (Substitution)
m<BAC + 149° = 180°
m<BAC = 180° - 149°
m<BAC = 31°
<x = <BAC (vertical angles)
m<x = 31° (substitution)
Answer:
its 32.

Use the given x and y values to write a direct variation equation
x=5, y=30
Answer:
The direct variation equation is y = 6x
Step-by-step explanation:
The direct variation equation is y = kx, where
k is the constant of variationTo find the value of k, use the initial values of x and y
∵ y = 5, y = 30
∵ y = k x
→ Substitute the values of x and y to find k
∵ x = 5 and y = 30
∴ 30 = k (5)
∴ 30 = 5k
→ Divide both sides by 5
∴ [tex]\frac{30}{5}=\frac{5k}{5}[/tex]
∴ 6 = k
→ Substitute it in the form of the equation
∴ y = 6x
The direct variation equation is y = 6x

Mitchell’s dog is 1/3 as old as Katie’s cat. The sum of their ages is 12 years. How old is Mitchell’s dog?
Answer:
Mitchell's dog is 3 years old
Step-by-step explanation:
9 x 1/3 = 3
9 + 3 = 12
To solve this I just thought of the multiples of three under 12 that if added to 3 are equal to 12 to find Katie's cat age. The multiples of three under 12 are 3, 6 and 9. It couldn't be 3 and 6+3=9 so it had to be 9. So if Katie's cat is 9, you just multiply 9 by 1/3 or divide it by 3 to find Mitchell's dog age.
