when you have a linear combination for example 3x + 2y equals negative 4 you adieu like terms and then multiply
Answer:
A. X = 30º
Step-by-step explanation:
The angle labeled x & the right angle are vertical angles to the one labeled 120º.
Therefore:
X + 90 = 120
Solve for x:
X + (90-90) = 120 - 90
X = 30
Hope this helps! Have a great day!
Answer:
The slope of the line given by the linear equation is -2
The slope of the line shown in the graph is -1
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
The rule of the slope of a line is m =
, where
- (x1, y1) and (x2, y2) are two points lie on the line
Let us use these rules to answer the question
∵ The linear equation is y = -2x + 7
→ By comparing it with the form of the linear equation above
∴ m = -2
∵ m is the slope of the line represented by the given equation
∴ The slope of the line given by the linear equation is -2
From the given figure
∵ The line passes through points (6, 0) and (0, 6)
∴ x1 = 6 and y1 = 0
∴ x2 = 0 and y2 = 6
→ Substitute them in the rule of the slope above to find it
∵ m = 
∴ m = -1
∵ m is the slope of the line shown in the graph
∴ The slope of the line shown in the graph is -1
Answer:
x ≥ 2
0 ≤ 20 (not quite sure if the question is right)
Step-by-step explanation:
x+18 ≥ 8x+4
x - 8x ≥ 4 - 18
-7x ≥ -14
x ≥ 
x ≥ 2
________________
15x-15 ≤ 15x+5
15x - 15x ≤ 5 + 15
0 ≤ 20
(I don't think this is the right question...cuz theres a 0)
