For the frieze pattern to the right , describe all transformations that map the pattern onto itself.
Select all that apply
A. Reflection across one or more horizontal lines
B. Reflection across one or more vertical lines
C. Glide reflection
D. Rotation
E. Translation
All transformations that map the pattern onto itself are; a horizontal translation and a reflection across a vertical line.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x).
All these translations have predetermined rules that we apply to the figures.
The congruence of a triangle can be obtain through Rotation; Translation; or Reflection.
For this particular strip pattern onto itself, can be obtained by a horizontal translation and a reflection across a vertical line
All transformations that map the pattern onto itself are; a horizontal translation and a reflection across a vertical line.

Solve using substitution.
y = 3x – 6.
y = 2x – 1
Answer:
x = 1 and y = 3
Step-by-step explanation:
To use substitution, you want to substitute something for another variable. So lets take the first equation and solve for y
2x - y = -1
2x = y - 1
2x + 1 = y
Now we can substitute 2x + 1 for y in the other equation
3x + 2x + 1 = 6
5x = 5
x = 1
now that we have x, we can get y
2(1) - y = -1
2 - y = -1
2 = y - 1
3 = y
So x = 1 and y = 3

The y-intercept of 2x - y = 6 is -6.
O False
True
Answer:
It is true
Step-by-step explanation:
Convert to slope-intercept form:
2x-y=6
-y=6-2x
y=-6+2x
y=2x-6
Since y=mx+b is the form we want, then b=-6, making the statement true.
Answer:
true
Step-by-step explanation:
you switch the 2x to the other side to get -y = 2x + 6
then you multiply everything by -1 to get y = -2x-6
-6 is the y int

Afterward, we apply the substitution rule, [tex]\displaystyle \lim_{x \to a} f(x) = f(a)[/tex], so basically I plugged in x = 3. Then evaluated f(3) = 2 due to the point (3,2).

what additional information could be used to prove ABC MQR using SAS?
Answer:
To prove that ΔABC ≅ ΔMQR using SAS, we show that two sides with the intersection angle are congruent.
From the diagram, it is shown that CA is congruent to RM.
From the first option, given that m∠A = 64° and AB = MQ = 31 cm, then we have CA = RM, AB = MQ, and CAB = RMQ (i.e. m∠A = m∠M = 64°).
This shows that the first option is correct.
From the second option, given that CB = MQ = 29 cm, then we have CA = RM, CB = MQ, but ACB is not congruent to RMQ.
Thus the second option in not correct.
From the third option, m∠Q = 56° and CB ≅ RQ, then we have CA = RM, CB = RQ, ACB = 60°, but we do not know the value of MRQ.
Thus the third option is not correct.
From the fourth option, m∠R = 60° and AB ≅ MQ, then we have CA = RM, AB = MQ, RMQ = 64°, but we do not know the value of CAB.
Thus the fourth option is not correct.
From the fifth option, AB = QR = 31 cm, then we have CA = RM, AB = QR, but we do not know the value of CAB or MRQ.
Thus, the fifth option is not correct.
Therefore, the additional information that could be used to prove ΔABC ≅ ΔMQR using SAS is m∠A = 64° and AB = MQ = 31 cm
The additional information could be used to prove ABC≅MQR using SAS will be m∠R = 60° and AB≅MQ. Option D is correct.
What are the conditions of the congruent triangle?Triangles that are equivalent in terms of size and form are known as congruent triangles.
The conditions for ABC≅MQR are;
m∠R = 60°
AB≅MQ
Using the new data, it is possible to demonstrate that m∠R = 60° and AB is equal to the MQ will result in ABC≅MQR using SAS.
Hence option D is correct.

Genna purchased a pair of shoes on a web site.The original price of the shoes was $120. She used the coupon code to receive a 20% discount. The web applied a 15% service fee to the discounted price. Genna's shoes were less than the original price by what percent
Answer:
$116
Step-by-step explanation:
the total discount is 20-15 = 5%
the dicount = (5*120)/100 = $4
So she bought it with price = 120 - 4 = $116
Answer: 8%
Step-by-step explanation:
1. Apply the discount to the original price
20% of 120 (0.2*120) is 24, thus Genna saves 24 dollars
120-24 = 96 (the new price of the shoes, with the coupon applied)
2. Apply the service fee to the discounted price
15% of 96 (0.15*96) = 14.4
This number is the amount of money being added to the discounted price, as it is an additional fee
96 + 14.4 = 110.4
3. Find the percent discount Genna's shoes are using the new price.
1 - (New price/Old price) = Percent discount
110.4/120 = 0.92
1 - 0.92 = 0.08
The shoes are 92% of the original price. Thus, the shoes are 8% less than the original price.

I WILL GIVE BRAINLIEST TO RIGHT ANSWER: The length of a bridge on a map is 1.5 cm. What is the actual length of the bridge in meters if the map is drawn at a scale of 1 : 40,000.
Answer: 600 m
Step-by-step explanation:
Imagine we have measured a distance as 1.5 cm on this map, and we want to find out how far this is in real life.
To work out the distance in real life, we need to multiply this length by 40,000.
This gives 1.5 cm × 40,000 = 60,000 cm which is 600 m or 0.6 km.
Sol b : Alternatively, we could have just remembered that each 1 cm on the map is 0.4 km in real life.
Hence, 1.5 cm on the map must be 1.5 × 0.4 km = 0.6 km in real life.

5) The sales tax in the town where Amanda lives is 5%. Amanda paid $35
in sales tax on a new stereo. What was the price of the stereo?*
O a. $14.29
O b. $1.75
O c. $700
O d. $3,500
Answer:
$700
Step-by-step explanation:
Given that,
The sales tax in the town where Amanda lives is 5%.
Amanda paid $35 in sales tax on a new stereo.
We need to find the price of the stereo. Let it is x. Using the formula for percentage as follows :
[tex]\%=\dfrac{\text{sales tax}}{\text{total}}\times 100\\\\5\%=\dfrac{35}{x}\times 100\%\\\\x=\dfrac{35\times 100\%}{5\%}\\\\=\$700[/tex]
So, the price of the stereo is $700. Hence, the correct option is(c).

g Find the required probabilities using the exponential density function f(t) = 1 λ e−t/λ, [0, [infinity]). The time t (in years) until failure of a component in a machine is exponentially distributed with λ = 3.5. Find the probabilities that the lifetime of a given component will be less than 1 year, more than 2 years but less than 4 years, and at least 5 years. (Round your answers to three decimal places.) (a) less than 1 year (b) more than 2 years but less than 4 years (c) at least 5 years
Answer:
(a) less than 1 year =0.751488
(b) more than 2 years but less than 4 years = 0.2458
(c) at least 5 years= 0.760331
Step-by-step explanation:
f(t) = 1 λ e−t/λ, [0, [infinity])
First we calculate the probability for an exponential random variable X with parameter λ
P (X= t) = ∫ 1 λ e−t/λ, dt
P (x=t) = e−t/λ,
λ = 3.5
Now P (X< 1 ) = ∫ 1 λ e−t/λ, dt [the limits are (-∞ to 1)]
= e−1/3.5= 0.751488
P ( 2<X< 4 ) = ∫ 1 λ e−t/λ, dt [ the limits are (2 to 4)]
=e−2/3.5- e−4/3.5
= e-0.57142-e-1.142857
= 0.5647-0.31890
= 0.2458
P (at least 5) = 1- P (x=5)
= 1-∫ 1 λ e−t/λ, dt [ the limits are (∞ to 5)]
= 1- e−5/3.5
= 1 - e-1.4285
= 1-0.239
= 0.760331
