Answer: Y = - 4 & x = 1
Step-by-step explanation:
Systems of linear equations: We will solve this using substitution but you can use 2 more ways.
7x + 2y = -1
2x - 4y = 19
Leave X alone first: -------------------
10x - 2y = 18
10x/10 = 18 + 2y/10
x = 9/5 + y/5
Solve for y:
7(9/5 + y/5) + 2y = -1
63/5 + 7y/5 + 2y - 1
63/5 + 7y/5 = 10y/5 = -1
63/5 + 17y/5 = -1 (-5/5)
17y/5 = -68/5 (cancel the 5)
y = -68/17
y = - 4 (Your Answer)
7x + 2(- 4) = -1
7x + (-8) = -1
7x = 7
x = 1
CHECK=
7(1) + 2(-4) = -1
7+ (-8) = -1.
-1=-1
Answer:
Step-by-step explanation:
Negative 2/3 means -2/3
Hence;
1 + (-2/3) - (-m)
= 1 - 2/3 + m (positive x negative = negative, negative x negative = positive)
Substituting 9/2 for the value of m
= 1 - 2/3 + 9/2
The L.C.M = 6
= ( 6 - 4 + 27)/6
= 29/6
Answer:
5 units
Step-by-step explanation:
Even if there is a transformation, it is asking for the length.
Therefore the length of WZ is 5 units
Answer:
Step-by-step explanation:
34 and m=7
Answer:
x = - 9
Step-by-step explanation:
Given g(x) = - x - 3 and g(x) = 6, then equate, that is
- x - 3 = 6 ( add 3 to both sides )
- x = 9 ( multiply both sides by - 1 )
x = - 9
