Answer:
y = - 3x² - 24x - 60
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (- 4, - 12 ), thus
y = a(x + 4)² - 12
To calculate a substitute (- 7, - 39) into the equation
- 39 = a(- 7 + 4)² - 12 ( add 12 to both sides )
- 27 = 9a ( divide both sides by 9 )
- 3 = a
y = - 3(x + 4)² - 12 ← in vertex form
Expand (x + 4)²
y = - 3(x² + 8x + 16) - 12
= - 3x² - 24x - 48 - 12
y = - 3x² - 24x - 60 ← in standard form
= - 3(x²

if a =1 + r + 7r and b = 1 -r ,find an expression that equals A+ 3B in standard form. Answer:
Answer:
A+3B=4+5r
Step-by-step explanation:
Given that,
A = 1+r+7r
B = 1-r
We need to find an expression that is equal to A+3B.
Putting the values of A and B in A+3B, we get :
A+3B = 1+r+7r + 3(1-r)
=1+8r+3-3r
=(1+3) +(8r-3r)
=4+5r
Hence, the values of A+3B equals 4+5r.

Step-by-step explanation:
You have three consecutive odd integers. Four times the smallest decreased by 5 is the same as the largest increased by 12. What is the smallest of the integers?
Answer:
The smallest of the integers is 7
Step-by-step explanation:
Let the integers be x, y and z
From the question, the integers are consecutive odd integers.
Hence,
If the smallest of the integers is x and the largest is z, then we can write that,
x + 2 = y and
y + 2 = z
Then, x + 2 + 2 = z
∴ x + 4 = z ....... (1)
From the question, four times the smallest decreased by 5 is the same as the largest increased by 12, that is
4x -5 = z + 12 ....... (2)
Put the value of z = x + 4 in equation (1) into equation (2),
We then get
4x - 5 = x + 4 + 12
4x - x = 4 + 12 + 5
3x = 21
x = 7
Hence, the smallest of the integers is 7
The other integers are 9 and 11 ( y= 9 and z = 11)
find DF if D is between E and F, ED = 6x-4 , DF =3x+5 and EF= 46
Answer:
DF= 20
Step-by-step explanation:
6x-4+3x-5=46
then you solve for x (x=5).
then plug it it : 3(5)+5=20
Value of DF is 20 unit
Given that;ED = 6x - 4
DF = 3x + 5
EF = 46
Find:Value of DF
Computation:We know that;
EF = ED + DF
46 = 6x - 4 + 3x + 5
46 = 9x + 1
9x = 45
x = 5
Value of DF = 3x + 5
Value of DF = 3(5) + 5
Value of DF = 15 + 5
Value of DF = 20 unit

does a function have to be linear
Answer:
Hi there
Step-by-step explanation:
A linear function is a type of function and so must follow certain rules to be classified as a “function”. For example, functions can only have one output for each input. On the other hand, equations are just statements that make two things equal, like x = y or 52x = 100.

What are the next two numbers in this sequence?
Answer:
74, 138
Step-by-step explanation:
The numbers seem to be increasing by powers of 2. 14 - 12 = 2 = 2¹, 18 - 14 = 4 = 2², etc. Therefore, the next 2 numbers would be 42 + 2⁵ = 74 and 74 + 2⁶ = 138.
The commute time to work in the U.S. Has a bell shaped distribution with a population mean of 24.4 minutes and a population standard deviation of 6.5 minutes. What proportion of the population has a commute time: a) between 11.4 minutes and 37.4 minutes? (1 pt) b) less than 11.4 minutes? (1 pt) c) greater than 37.4 minutes? (1 pt)
Answer:
1. 0.9544
2. 0.0228
3. 0.0228
Step-by-step explanation:
The computation is shown below;
As we know that
At Normal distribution
[tex]P(X < A) = P(Z < \frac{(A - mean)}{standard deviation})[/tex]
As per the question, the data provided is as follows
Mean = 24.4 minutes
Standard deviation = 6.5 minutes
Based on the above information
P(11.4 < X < 37.4) = P(X < 37.4) - P(X < 11.4)
= P(Z < (37.4 - 24.4) ÷ 6.5) - P(Z < (11.4 - 24.4) ÷ 6.5)
= P(Z < 2) - P(Z < -2)
= 0.9772 - 0.0228
= 0.9544
2. P(X < 11.4) = 0.0228
3. P(X ≥ 37.4) = 1 - P(X < 37.4)
= 1 - 0.9772
= 0.0228

1. A new pizza shop opened up and started out $6,378.60 in the hole. Their first month being open they
sold 56 pizzas ($6.63 profit each) and 91 sodas ($2.85 profit each). Their bills for the first month were
$1,547.76. How much money do they still need to make to break even?
Answer:
7212.53, i belive
Step-by-step explanation:
56 x 6.33 = 354.48
91 x 2.85 = 259.35
259.35 + 354.48 = 613.83
1547.76 - 613.83 = 933.93
6278.60 + 933.93 = 7212.53
Xian and his cousin Kai both collect stamps. Xian has 52 stamps, and Kai has 72 stamps. The boys recently
joined different stamp-collecting clubs. Xian's club will send him 12 new stamps per month. Kai's club will
send him 8 new stamps per month. After how many months will Xian and Kai have the same number of
stamps? How many stamps will each have?
After
months Xian and his cousin will have
stamps each.
Answer:
Step-by-step explanation:
Let the x be the number of months.
In x months, xian will have:
(52+16x) stamps
and kai will have:
(76+12x)stamps
To find out how many months they will have the same number of stamps, we evaluate the two expressions:
52+16x=76+12x
52+4x=76
4x=24
x=6
So xian and kai will have the same number of stamps after 6 months.
Using either of two expressions, each will have:
52+16(6)=76+12(6)= 148 stamps.

The proceeds from a car wash are directly proportional to the number of cars washed. The total after 9 cars was $180. How much can be raised if 60 cars
are washed?
60 cars washed?
Answer:
$1200
Step-by-step explanation:
180 divided by 9 is 20, so they earned $20 per car washed. They want to wash 60 cars, and if they wash 60 cars they would earn $1200. (60 x 20)
Answer:
$1200
Step-by-step explanation:
Our revenue is directly proportional to the number of cars. That means our revenue is increasing at a constant rate, and thus, we are getting the same amount of money per car. That means we can find out how much we get from washing 1 car.
[tex]\frac{180}{9} = 20[/tex]
$20 per car.
If we washed 60 cars, we'd earn 60 * $20:
[tex]60*20 = 1200[/tex]
Answer: $1200
