If ΔABC ≅ ΔEDF where the coordinates of A(−1, 1), B(2, 4), and C(3, 1), what is the measure of EF?
3
3.2
4
4.6
Answer:
4 is the correct answer.
Step-by-step explanation:
If you're taking FLVS math then this is the right answer, I got it correct on my test.
The required measure of EF is 4. Option c is correct.
ΔABC ≅ ΔEDF
A(−1, 1), B(2, 4), and C(3, 1).
In congruent geometry, the shapes that are so identical. Can be coincide to themselves.
Here,
ΔABC ≅ ΔEDF
SO, AC = EF
EF = [tex]\sqrt{(3+1)^2+(1-1)^2 }[/tex]
EF = 4
Thus, the required measure of EF is 4.

Linear combination of matrices .
Multiplying a matrix by a scalar is equivalent to multiplying each entry in the matrix by that scalar:
[tex]A=\begin{bmatrix}0&-3\\-5&5\end{bmatrix}\implies3A=\begin{bmatrix}0&-9\\-15&15\end{bmatrix}[/tex]
[tex]B=\begin{bmatrix}-2&-6\\2&5\end{bmatrix}\implies-6B=\begin{bmatrix}12&36\\-12&-30\end{bmatrix}[/tex]
Now combine them:
[tex]3A-6B=3A+(-6B)=\begin{bmatrix}0+12&-9+36\\-15+(-12)&15+(-30)\end{bmatrix}=\begin{bmatrix}12&27\\-27&-15\end{bmatrix}[/tex]

Solve the following equation: *
3(2x - 5) = 9x + 24
Enter your math answer
Answer:
4. x = 11
5. x = -13
Step-by-step explanation:
4. 3x + 7 = 5x - 15
-7 -7
3x = 5x - 22
-5x -5x
-2x = -22
-2x/-2 = -22/-2
x = 11
5. 3(2x - 5) = 9x + 24
6x - 15 = 9x + 24
+15 +15
6x = 9x + 39
-9x -9x
-3x = 39
-3x/-3 = 39/-3
x = -13

What is the slope of the line?
Answer:
y = 2x-3.
Step-by-step explanation:
Slope is y =mx+b. If we look at the graph, the line passes by (0,-3) and (1,-1). Taking rise over run, (y/x), we can find out that y goes up 2 and x goes right 1. This means that it is a positive slope and that slope would be 2/1, simplified to just 2.

shampoo if 8 ounces cost $0.99 and 12 ounces cost $1.47.
b) cereal if 31 ounces cost $1.50 and 16 ounces cost $0.77.
c) soda if 3 cans cost $1.77 and 5 cans cost $1.79.
PLEASE HELPPP
Answer:
A. 12 oz. for $1.47
B. 16 oz for $0.77
C. 5 cans for 1.79
Step-by-step explanation:
A. Divide them both, cost by quantity.
0.99/8=0.123
1.47/12=0.1225
The second option is better since its 0.005 less than the first option.
B. Again, divide both options.
0.77/16=0.04125
1.50/31=0.04838
Second option because it is 0.00713 cents cheaper.
C. 1.77/3=0.59
1.79/5= 0.36
Second option is .23 cents cheaper than the first option.
find the measure of angle J .will mark brainiest
Answer:
<J=51°
Step-by-step explanation:
3x-2+4x-9+3x-9=180
10x-20=180
10x=200
x=20
<J=3x-9=3(20)-9=60-9=51°
Answer: Angle J = 51°
Step-by-step explanation: All angles add up to 180° in a triangle, so add every angle and set it equal to 180°.
(3x - 2) + (3x - 9) + (4x - 9) = 180
Add like terms:
10x - 20 = 180
Add 20 to both sides:
10x = 200
Divide both sides by 10:
x = 20
Now, plug x into angle J:
3(20) - 9
60 - 9
51
Angle J = 51°

<3. <7, and <4
<2. <3 and <7
Answer:
Option (4)
Step-by-step explanation:
From the figure attached,
Lines 'c' and 'd' are the parallel lines a transversal line is intersecting these lines.
m∠2 = 124° [Corresponding angles]
m∠7 = 124° [Vertically opposite angles]
m∠2 = m∠3 = 124° [Vertically opposite angles]
Therefore, angles ∠2, ∠7 and ∠3 measure 124°.
Option (4) will be the answer.
How do you write 1.65x10^8: 2x10^3 in scientific notation?
I'm guessing you're talking about the ratio,
(1.65 x 10⁸) / (2 x 10³)
You can cancel the lowest power of 10:
(1.65 x 10⁸) / (2 x 10³) = (1.65 x 10⁵) / 2
Divide 1.65 in half to get 0.825. So we have
(1.65 x 10⁸) / (2 x 10³) = 0.825 x 10⁵
Move the decimal point to the right, which involves multiplying by a factor of 10 which is taken from 10⁵, so we end up with
(1.65 x 10⁸) / (2 x 10³) = 8.25 x 10⁴
A phone company charges a base fee of $12 per month plus an additional charge per minute. The monthly phone cost LaTeX: CC can be represented by this equation: LaTeX: C=12+a\cdot mC = 12 + a ⋅ m , where LaTeX: aa is the additional charge per minute, and LaTeX: mm is the number of minutes used. Which equation can be used to find the number of minutes a customer used if we know LaTeX: CC and LaTeX: aa?
Answer: M=(c-12)-a
Step-by-step explanation:
this is because your trying to find m and 12a doesn't represent that.

Evaluate : (r - 3)³ + r² if r = -3 and s = -4. Show all the steps of working for this question.
I have a math test please give me the right answer!!
Answer:
-207
Step-by-step explanation:
Using r= -3, we can substitute r in the whole equation as (-3) which gives you: ((-3)-3)^3 +(-3)^2. Now you can calculate these values in a step by step manner. (-6)^3 +9 then to -216 +9 which brings you to the answer of -207.
Answer:
225
Step-by-step explanation:
(r - 3)³ + r² if r = -3 and s = -4
(-3 - 3)^3 + (-3)^2
(-6)^3 + (9)
(-6 x -6 x -6) + 9
-216 + 9

What 2 numbers have a difference of 8
Step-by-step explanation:
10-2=8 has the difference of 8
The difference of two numbers is obtained using the subtraction operation ; Hence, two numbers whose difference gives a value of 8 are 16 and 8.
There are many possible values where, the value of the two numbers will give a value of 8.
They include;
10 - 2 = 816 - 8 = 812 - 4 = 813 - 5 = 89 - 1 = 8Therefore, two numbers whose difference gives a value of 8 are 16 and 8.

Which statement correctly describes the relationship between the graph of f(x) and the graph of g(x)=f(x)−4?
The graph of g(x) is the graph of f(x) translated 4 units down.
The graph of g(x) is the graph of f(x) translated 4 units right.
The graph of g(x) is the graph of f(x) translated 4 units up.
The graph of g(x) is the graph of f(x) translated 4 units left.
Answer:
The graph of g(x) is the graph of f(x) translated 4 units down.
Explanation:
Given the function f(x) and g(x) = f(x)-4
This means that the function g(x) is 4 less than the function g(x) i.e the function g(x) is reduced by 4. Since the negative values on a graph are located from the origin down the negative y axis and towards the negative x axis, we can conclude that the graph g(x) translated 4 units down. of f(x). This is translated along the y axis because the function g(x) serves as the output for all values on input variable x.
The g(x) can be written as a function of y i.e we can rewrite it as y = f(x)-4.
Hence the correct option is The graph of g(x) is the graph of f(x) translated 4 units down.
