8. Translate triangle ABC 3 units right and 2 units down.
What are the coordinates for point A′?
A. (–4, –2)
B. (0, –2)
C. (1, –1)
D. (1, 3)
Answers
Answer:
First get the point of A which is (-2,1). Then 3 units to the right means adding 3 to x value so -2+3=1, x will be 1. Then going 2 units down means the y value needs to subtract 2. 1-2=-1
Final A will then be (1,-1)

Answer:
30.8, 37
Step-by-step explanation:
First, we know that the angles in a triangle add up to 180, so 180-75-48= m∠G=57°. Then, using sohcahtoa, we have tan(G) = DF/FG = DF/20. tan(G) ≈ 1.54, so 20(1.54)=DF≈ 30.8
Next, using sohcahtoa, we have cos(G) = FG/DG = 20/DG. cos(G)≈0.54, and 20/0.54=DG ≈ 37

I don't know how to get #7, I'm sorry.
Step-by-step explanation:
5) 4x - 3(8 - x) = -3
4x - 24 - 3x = -3
+24 +24
4x - 3x = 21
x = 21
y = 8 - 21
y = -13
6) x + 3y = 14
-3y -3y
x = -3y + 14
-5(-3y + 14) + 6y = -28
15y + 14 +6y = -28
21y + 14 = -28
-14 -14
21y = -42

y = -2
x + 3(-2) = 14

Answer:
The linear equations which have one solution are C. [tex]4\cdot (-6) +4 = 2\cdot (r-3)[/tex], D. [tex]2\cdot (-4) = 5\cdot (r-3) +3[/tex] and E. [tex](20-1) +3\cdot r = 5\cdot (r-2) + 3[/tex].

From Algebra we know that a system of linear equation has a unique solution when the number of variables is equal to the number of equations. Now we proceed to check if each option fulfills this condition:
A. [tex]5\cdot x -1 = 3\cdot (r + 11)[/tex]: Number of equations: 1/Number of variables: 2 [tex]\{x, r\}[/tex]

The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + \frac{R}{n} )^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
The amount Liam got on his 18th birthday is $34,251.05.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + \frac{R}{n} )^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
Example:
P = 200
R = 2%
t = 3 years
compounded annually, n =1
A = $212.24
We have,
Principal = $20,000
Rate = 3%
There are 4 quarters in a year.
It is compounded quarterly.
This means,
n = 4
t = 18 years
The amount compounded quarterly.
A = 20,000 [tex](1 + 0.0075)^{72}[/tex]
A = 20,000 x [tex]1.0075^{72}[/tex]
A = $34,251.05
Thus,
The amount Liam got on his 18th birthday is $34,251.05.

What are the assumptions that we should check before conducting the hypothesis test?
Answers
Answer:
Assumptions before conduction hypothesis test are mentioned below in the explanation.
Step-by-step explanation:
As this question is incomplete, and I will try my best to answer this question.
We are asked in this question to write the assumptions that we check before conducting the hypothesis test.
Solution:
Assumptions of hypothesis test:
1. We have to make assumption that all the observations are independent.
2. Secondly, we need to take assumption that, all the parent population of the data reflects normal distribution.
3. Furthermore, we need to assume that experimental error or random error is independently identical and normally distributed with mean "0" and variance of (σ^2).
Above are the assumptions that we should check before conducting hypothesis test.

given
weight (w) = 420
g = 10 m/s²
then
W = m* g
420 = m * 10
m = 420/10
m = 42 kg

Answer:
Step-by-step explanation: weight = 420N
