Answer:
The answer to your question is the last choice.
Step-by-step explanation:
The first column represents the x
The second column represents the y
The third column represents the z
The last column represents the independent term
The first line represents the first equation
The second line represents the second equation
The third line represents the last equation
From the previous information, we conclude that the answer is the last choice.
13) If T(n) = 2n-7, what is the 5th term?
n is the number of the term you are looking for. In this instance, n is equal to 5.
T(5) = 2(5) - 7
T(5) = 10 -7
T(5) = 3
The 5th term is 3.
17) inequality based on the line number.
Since the line does not extend in any direction outward. It means that the range should be within -3 and 3.
Solid circle means that -3 is equivalent to x
hollow ciccle means that 3 is not x.
-3 <u><</u> x < 3
x = any number from -3 upto 2.
Answer:
(2, - 4 )
Step-by-step explanation:
Given the 2 equations
10x + 7y = - 8 → (1)
7x + 7y = - 14 → (2)
Subtract (2) from (1) term by term to eliminate y
(10x - 7x) + (7y - 7y) = - 8 - (- 14) , that is
3x = 6 ( divide both sides by 3 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
10(2) + 7y = - 8
20 + 7y = - 8 ( subtract 20 from both sides )
7y = - 28 ( divide both sides by 7 )
y = - 4
solution to the system of equations is (2, - 4 )
Answer:x>2
Step-by-step explanation:
4x/4>8/4
Correct Question: If m∠JKM = 43, m∠MKL = (8x - 20), and m∠JKL = (10x - 11), find each measure.
1. x = ?
2. m∠MKL = ?
3. m∠JKL = ?
Answer/Step-by-step explanation:
Given:
m<JKM = 43,
m<MKL = (8x - 20),
m<JKL = (10x - 11).
Required:
1. Value of x
2. m<MKL
3. m<JKL
Solution:
1. Value of x:
m<JKL = m<MKL + m<JKM (angle addition postulate)
Therefore:
Solve for x
Subtract 8x from both sides
Add 11 to both sides
Divide both sides by 2
2. m<MKL = 8x - 20
Plug in the value of x
m<MKL = 8(17) - 20 = 136 - 20 = 116°
3. m<JKL = 10x - 11
m<JKL = 10(17) - 11 = 170 - 11 = 159°
