Use function notation to write the equation of the line.
Answer:
the equation is f(x)= 2/3x -2. or c
Step-by-step explanation:
you know that it cant be d because the y- intercept is -2 not +2. and you know that it cant be b because it is a positive slope. to find the slope you need to find 2 points that that the line crosses through, like (0, -2) and (3,0). now you see that it goes up 2 and over 3. 2/3
f(x)= 2/3x -2
What are the coordinates of vertex F of parallelogram FGHJ? (–2, 2) (–2, 6) (–3, 4) (–4, 2)
Question:
Parallelogram f"g"h"j" is the final image after the rule ry-axis • t1,2(x, y) was applied to parallelogram fghj. The coordinates are f''(3,4), g''(2,2), h''(4,2) and j''(5,4)
what are the coordinates of vertex f of parallelogram fghj?
(–2, 2)
(–2, 6)
(–3, 4)
(–4, 2)
Given:
Given that the the coordinates of the parallelogram f''g''h''j'' is the final image after the rule ry-axis • t1,2(x, y) was applied to parallelogram fghj.
The coordinates are f''(3,4), g''(2,2), h''(4,2) and j''(5,4)
We need to determine the coordinates of vertex f of parallelogram fghj.
Reflection across y - axis:
The general rule to reflect the coordinate across y - axis is given by
[tex](x,y) \rightarrow (-x,y)[/tex]
Substituting the coordinate f''(3,4), we get;
[tex](3,4)\rightarrow (-3,4)[/tex]
Thus, the coordinates of f'' of reflection across the y - axis is (-3,4)
Translation T1,2(x, y):
The translation can be performed using the rule,
[tex]T_{1,2}(x,y)=(x+1,y+2)[/tex]
Now, substituting the coordinate (-3,4), we get;
[tex]T_{1,2}(-3,4)=(-3+1,4+2)[/tex]
[tex]T_{1,2}(-3,4)=(-2,6)[/tex]
Thus, the coordinates of vertex F is (-2,6)
Hence, Option b is the correct answer.
The answer is D) (-4,2) on Edge 2020
Roberto decorates rectangular signs. One sign is 2/3 foot long and 1/4 foot wide. Another sign is 1/2 foot long and 1/3 foot wide. It takes Roberto 3/4 hour to decorate a 1-square-foot sign. What is the total amount of time, in hours, it takes Roberto to decorate both signs. Show or explain each step you used to find your answer
Answer: It takes Him 1/4 hours to decorate both signs,
Step-by-step explanation:
Hi, since the area of a rectangle is equal to:
Area: length x width
Replacing with the values given;
Sign 1 =A1 = 2/3 x 1/4 =1/6 ft2
Sign 2 =A2= 1/2 x 1/3 = 1/6 ft2
If we sum both areas:
A1 +A2 = 1/6 + 1/6 = 2/6 ft2 = 1/3 ft2 (total area)
Since it takes Roberto 3/4 hour to decorate a 1-square-foot sign:
For 1/3 ft2
3/4 hour x 1/3 ft2 = 1/4 h
ITt takes Him 1/4 hours to decorate both signs,
It takes Roberto 1/4 hour to decorate both signs.
To find the total amount of time it takes Roberto to decorate both signs, we need to calculate the area of each sign first and then determine the time required for each based on the given rate of 3/4 hour per 1 square foot.
1: Calculate the area of each sign
First sign: The dimensions are 2/3 foot long and 1/4 foot wide. The area (A) is length × width.2: Calculate the total area of both signs
Total area (Atotal) = A1 + A2 = 1/6 + 1/6 = 2/6 = 1/3 square foot.
3: Calculate the total time to decorate both signs
It takes Roberto 3/4 hour to decorate 1 square foot. So, for 1/3 square foot:
Time = (3/4) × (1/3) = 1/4 hour.
Therefore, it takes Roberto 1/4 hour to decorate both signs.

B. Early redemption fee
C. Liquidity fee

PREVIOUS
Answer: early redemption fee
Step-by-step explanation:
The type of fee charged for withdrawing money from a CD before the date of maturation is Early redemption fee.
We have to determine the type of fee charged for withdrawing money from a CD before the date of maturation.
We have given
A. FDIC fee
What is the FDIC fee?
It required the largest taxpayer bailout in the year 2008 financial crisis, explained in a footnote on its schedule of fees for business accounts in the nation's states that it charges an FDIC insurance fee at the annual rate of 13 cents per $100.
It related to insurance so it is not correct option.
B. Early redemption fee
The fee may be required to make to a lender if we pay off a loan or mortgage before the scheduled term of the credit facility.
So the Banks and credit unions often charge a fee if you withdraw money before maturity.
Therefore the Option B is correct.
C. Liquidity fee
This is nothing but the liquidity facility providers that the borrower may from time to time agree to pay.
Therefore this is not correct option

The probability of winning the shell games if you randomly pick is 1 in 3. What would be the approximate probability of winning 4 games in a row?
Answer:
1 /81
Step-by-step explanation:
1/3 * 1/3 * 1/3 * 1/3 (One for each game) = 1/81
This question is based on the probability. Therefore, the approximate probability of winning 4 games in a row is [tex]\dfrac{1}{81}[/tex].
Given:
The probability of winning the shell games if you randomly pick is 1 in 3.
We need to calculate the approximate probability of winning 4 games in a row.
According to the question,
By using the formula of probability,
[tex]Probability = \dfrac{Number \, of \, favourable \, outcome}{Total \, number \,of\, Outcome}[/tex]
It is given that, probability of winning is 1 in 3.
Now, calculating the approximate probability of winning 4 games in a row is,
[tex]\dfrac{1}{3} \times\dfrac{1}{3} \times \dfrac{1}{3} \times \dfrac{1}{3} = \dfrac{1}{81}[/tex]

Use technology or a z-distribution table to find the indicated area.
The weights of apples in a bin are normally distributed with a mean of 143 grams and a standard deviation of 4.2 grams.
Approximately 30% of the apples weigh less than which amount?
133 g
B.) 135 g
C.) 137 g
D.) 141 g
Answer:
I think it's answer D. (141). :D
Step-by-step explanation:
30% of the apples weigh less than 141 grams.
What is z- distribution?The z-distribution, also known as the standard normal distribution or the standard Gaussian distribution, is a probability distribution that is often used in statistics. It is a special case of the normal distribution with a mean of 0 and a standard deviation of 1.
First, we need to find the z-score corresponding to a cumulative probability of 0.30.
Using the z-distribution table, we find that the z-score corresponding to a cumulative probability of 0.30 is approximately -0.52.
The z-score formula is given by:
z = (x - μ) / σ
Where:
z is the z-score
x is the value we want to find the corresponding z-score for
μ is the mean of the distribution
σ is the standard deviation of the distribution
Rearranging the formula to solve for x:
x = zσ + μ
x = -0.52 (4.2) + 143
x ≈ 140.94
Therefore, 30% of the apples weigh less than 141 grams.

Solve -6x + 19 = x-2. Check for extraneous solutions.
Answer:
x=3 one solution
Step-by-step explanation:
Let's solve your equation step-by-step.
−6x+19=x−2
Step 1: Subtract x from both sides.
−6x+19−x=x−2−x
−7x+19=−2
Step 2: Subtract 19 from both sides.
−7x+19−19=−2−19
−7x=−21
Step 3: Divide both sides by -7.
−7x /−7 = −21 /−7
x=3
Answer:
x = 3
Step-by-step explanation:
Solve -6x + 19 = x-2
Solve for x:
19 - 6 x = x - 2
Subtract x from both sides:
19 + (-6 x - x) = (x - x) - 2
-6 x - x = -7 x:
-7 x + 19 = (x - x) - 2
x - x = 0:
19 - 7 x = -2
Subtract 19 from both sides:
(19 - 19) - 7 x = -19 - 2
19 - 19 = 0:
-7 x = -19 - 2
-19 - 2 = -21:
-7 x = -21
Divide both sides of -7 x = -21 by -7:
(-7 x)/(-7) = (-21)/(-7)
(-7)/(-7) = 1:
x = (-21)/(-7)
The gcd of -21 and -7 is -7, so (-21)/(-7) = (-7×3)/(-7×1) = (-7)/(-7)×3 = 3:

∠ H = 84°
Step-by-step explanation:
Since HI = IJ then Δ HIJ is isosceles with ∠ IHJ = ∠ IJH, thus
∠IHJ = [tex]\frac{180-134}{2}[/tex] = [tex]\frac{46}{2}[/tex] = 23°
Similarly
Since HG = JG then Δ HGJ is isosceles with ∠ GHJ = ∠ GJH, thus
∠ GHJ = [tex]\frac{180-58}{2}[/tex] = [tex]\frac{122}{2}[/tex] = 61°
Thus
∠ H = ∠ GJH + ∠ IHJ = 61° + 23° = 84°
