what is the equation of the new function?
• Shift 5 units to the left.
• Shift 4 units down.
A. g(x) = 5x + 41 - 5
B. g(x) = 1x - 51 - 4
C. g(x) = 5x + 51 - 4
D. g(x) = 1x - 41 - 5
The required function after shifting its origin will be g(x) = |x + 5| - 4.
What is Shifting of Origin?
To shift the coordinates of origin to (h,k): Replace x by (x-h) and y by (y-k) in the given equation and get the new equation.
Here, given function f(x) = |x|
or y = |x|
Now, Shift 5 units to the left. x replaces with x - (-5) = x + 5
Shift 4 units down, y replaces with y -(-4) = y + 4
Now equation after shifting ,
y - k = | x - h|
y = |x -h| + k
y = |x - (-5)| +(-4)
g(x) = |x+5|-4
Thus, The required function after shifting its origin will be g(x) = |x + 5| - 4.

The temperature in Fairbanks, Alaska, changed from 0F at 6 pm to 4F at 11 pm . Between 11 pm and 5 am , the temperature dropped by 6 degrees . Which number line represents the temperature at 5 am
The number line extending towards -2 represents the correct number line.
What is number line?
A line on which numbers are marked at intervals, used to illustrate simple numerical operations.
Given is the temperature in Fairbanks, Alaska, changed from 0 F at 6 pm to 4 F at 11 pm . Between 11 pm and 5 am , the temperature dropped by 6 degrees.
Between 6 pm and 11 pm : 4 - 0 = 4 F
The temperature at 5 AM would be : 4 F - 6 F = - 2 F
Therefore, the number line extending towards -2 represents the correct number line.

A company plans to launch a new product. They have traditionally had a 60% success rate with the launch of new products. Market research predicts that a positive test market results is 80% of successfully launched products and a positive market result for 30% of failed product launches. A) If a market test result comes back negative, what is the probability that the product will be successfully launched?
Answer:
The probability that the product will be successfully launched given that the market test result comes back negative is 0.30.
Step-by-step explanation:
Denote the events provided as follows:
S = a product is successfully launched
P = positive test market result
The information provided is:
P (S) = 0.60
P (P | S) = 0.80
P (P | S') = 0.30
Then,
P (P' | S) = 1 - P (P | S) = 1 - 0.80 = 0.20
P (P' | S') = 1 - P (P | S') = 1 - 0.30 = 0.70
Compute the probability of positive test market result as follows:
[tex]P(P)=P(P|S)P(S)+P(P|S')P(S')[/tex]
[tex]=(0.80\times 0.60)+(0.30\times 0.40)\\\\=0.48+0.12\\\\=0.60[/tex]
The probability of positive test market result is 0.60.
Then the probability of negative test market result is:
P (P') = 1 - P (P)
= 1 - 0.60
= 0.40
Compute the probability that the product will be successfully launched given that the market test result comes back negative as follows:
[tex]P(S|P')=\frac{P(P'|S)P(S)}{P(P')}[/tex]
[tex]=\frac{0.20\times 0.60}{0.40}\\\\=0.30[/tex]
Thus, the probability that the product will be successfully launched given that the market test result comes back negative is 0.30.

If 4 out of 5 People at the picnic are children and there are 24 children at the picnic,many adults are there?
Answer:
6
Step-by-step explanation:
4/5 of the people at the picnic are children. There are 24 children. So 24 is 4/5 of the whole. You ÷4 to find 1/4. This is 6. So you add on the 6 as 1/4 add 4/5 equals the whole number of people there are at the picnic, 5/5. 24 add 6 is 30 so there are 30 le e at the picnic, and 6 adults.
5. Two blueberry farms are similar in shape. The ratio of the side lengths of
the farms is 5:6, and the smaller farm has a perimeter of 360 yards. The
cost to dig a trench is $0.75 per yard. What is the cost to dig a trench
around the larger blueberry farm?
Answer:It would cost $270 to dig
Step-by-step explanation:<!>Brainliest Apprecatied<!> :D
Answer: $324
Step-by-step explanation:
For this question, many people think the answer is 270, but that's wrong.
Since the ratio is 5:6 and the smaller farm perimeter we can put that into an ratio equation.
x will be the perimeter of the bigger farm
5/6=360/x
5x=2160
5x/5=2160/5
x=432 yards
That's the perimeter, now to find the cost it would be 432*0.75 which is $324.

Answer:
negative 5 over 32 degrees Fahrenheit
Step-by-step explanation:
Given the following :
Change in temperature per day = (- 5/32)°F
Waht will be the change in temperature after 3 days :
(-5/32)°F × 3 = ( - 15/96)°F
-15/96 = (-5/32)°F
Hence, the change in temperature will be :
negative 5 over 32 degrees Fahrenheit

9y = -27
x + y = -1
Answer:
(x, y) = (3, -4)
Step-by-step explanation:
A graphical solution is often quick and easy.
(x, y) = (3, -4)
_____
These equations can be solved algebraically by dividing the first by 3, then subtracting the second.
(3x +9y)/3 -(x +y) = (-27)/3 -(-1)
x +3y -x -y = -9 +1
2y = -8
y = -4
x = -1 -y = -1 -(-4) = 3 . . . from the second equation
The solution is (x, y) = (3, -4).

Write the equation in slope-intercept form: 6x + 2y = 10.
Answer: y=-3x+5
Step-by-step explanation:
6x+2y=10
Solve for y
2y=-6x+10
y=-3x+5
Answer: y = -3x + 5
Step-by-step explanation:
Slope intercept form is y = mx + b so all you need to do is put the equation into that format.
6x + 2y = 10
2y = 10 - 6x
y = -3x + 5

Given f(x) = -3x + 4, solve for x when f(x) = 1
(Will mark brainliest)
Answer:
x=1
Step-by-step explanation:
f(x) is a fancy way of saying Y. So whenever you see that, you can just say its y= something.
y=-3x+4
1=-3x+4
Move the -3x to the other side where the one is. By doing this, the 3x will become positive.
3x+1=4
Now just subract one from 4
3x=3
And divide 3 from both sides.
x=1
USE ESTIMATION Mr. Lycan is considering buying clay from two art supply companies. Company A sells 50-pound containers of clay for $24, plus $42 to ship the total order. Company B sells the same clay for $28, plus $25 to ship the total order. a. Write equations for the total cost of ordering clay from each company. b. Graph the equations on the same coordinate plane. Examine the graph to estimate how much Mr. Lycan would have to order for the cost of ordering clay from each company to be the same. c. Check your estimate by substituting into each original equation. How reasonable is your estimation? Justify your reasoning.
Answer:
y=$24x+$42 A
y=$28x×$25 B
Step-by-step explanation:
The required system of the equation is y = 42 + 24x and y = 25 + 28x, and a graph of the solution has shown.
What is the equation?The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
Here,
let x be the number of the 50 pounds containers of clay ordered.
According to the question,
For company A,
y = 42 + 24x - - - - (1)
For company B,
y = 25 + 28x - - - - (2)
Equating both the equation,
42 + 24x = 25 + 28x
17 = 4x
x = 17 / 4
x = 4.25
Put this value in equation 1
y = 42 + 24(4.25)
y = $144
Thus, the required system of the equation is y = 42 + 24x and y = 25 + 28x, and a graph of the solution has shown.

On a 28-question test, there are 2-point questions, 4-point questions, and 5-point questions. The test is worth a total of 100 points. There are twice as many 2-point questions as 5-point questions on the test. How many 2-point questions are on the test?
Answer: Number of 5-point question = 4
Number of 2-point questions =8
Number of 4-point question = 16
Step-by-step explanation:
Let x = Number of 5-points question.
then, Number of 2- point question = 2x
Also, Let y = Number of 4-point question.
Now, Total question : x+y+2x =28
⇒ 3x+ y =28 (i)
Total marks = 5x + 2 (2x)+4=100
⇒ 5x+4x+4y=100
⇒ 9x+4y=100 (ii)
Multiply 3 on both sides of (i), we get
9x+3y = 84 (iii)
Subtract (iii) from (ii), we get
y= 16
Put this in (i0, we get
3x+(16)=28
⇒ 3x = 12
⇒ x=4
Now, Number of 5-point question = 4
Number of 2-point questions = 2(4)=8
Number of 4-point question = 16
Answer
Answer: Number of 5-point question = 4
Number of 2-point questions =8
Number of 4-point question = 16
Step-by-step explanation:
Let x = Number of 5-points question.
then, Number of 2- point question = 2x
Also, Let y = Number of 4-point question.
Now, Total question : x+y+2x =28
⇒ 3x+ y =28 (i)
Total marks = 5x + 2 (2x)+4=100
⇒ 5x+4x+4y=100
⇒ 9x+4y=100 (ii)
Multiply 3 on both sides of (i), we get
9x+3y = 84 (iii)
Subtract (iii) from (ii), we get
y= 16
Put this in (i0, we get
3x+(16)=28
⇒ 3x = 12
⇒ x=4
Now, Number of 5-point question = 4
Number of 2-point questions = 2(4)=8
Number of 4-point question = 16
