Answer:
Step-by-step explanation:
We translate the phrase into an equation:
Then we simplify:
Positive and negative doesn’t matter. Steepest slope is the smallest or largest number.
In this case D. -4
Answer: x = 1, y = - 5
Step-by-step explanation:
The given system of linear equations is expressed as
x - 2y = 11- - - - - - - - - - - - -1
- x + 6y = - 31- - - - - - - - - - - -2
We would eliminate x by adding equation 1 to equation 2. It becomes
- 2y + 6y = 11 - 31
4y = - 20
Dividing the the left hand side and the right hand side of the equation by 4, it becomes
4y/4 = - 20/4
y = - 5
Substituting y = - 5 into equation 1, it becomes
x - 2 × - 5 = 11
x + 10 = 11
Subtracting 10 from the left hand side and the right hand side of the equation, it becomes
x + 10 - 10 = 11 - 10
x = 1
A=1/2 bh
1/2 bh=A
h=2A/b
Answer: h=2A/b
Answer:
True
Step-by-step explanation:
Evaluate 18 x - 2 (3 x + 1) = 5 x - 16 where x = -2:
-2×18 - 2 (1 - 2×3) = -2×5 - 16
3 (-2) = -6:
-2×18 - 2 (-6 + 1) = -2×5 - 16
1 - 6 = -5:
-2×18 - 2-5 = -2×5 - 16
18 (-2) = -36:
-36 - 2 (-5) = -2×5 - 16
-2 (-5) = 10:
10 - 36 = -2×5 - 16
5 (-2) = -10:
10 - 36 = -10 - 16
10 - 36 = -26:
-26 = -10 - 16
-10 - 16 = -26:
-26 = -26
-26 is equal to -26:
Answer: True
