1) The y- axis is where x = 0, so the line "y = -1/2x - 3" will cross the y-axis when x = 0. You plug in "x = 0" into the equation, and get y = 0 -3, so y = -3. That means the line " y = -1/2x - 3" will cross the y-axis ar (0, -3)
2) If there are 2 parallel lines, then there is no solution, because the definition of parallel lines is, " 2 lines in the same plane, that never meet." That makes the solution inconsistent.
Answer:
C
Step-by-step explanation:
add the two x^2 parts = 10 x^2
so answer is B or C
add the constants 7 + 6 = 13 so answer C
The solution of (3,13) means you need to create two lines that satisfy x = 3 and y = 13
The two lines can be anything as long as they give this solution
For example, if you wrote x + y = 16 (you know their values already)
Then write another y - x = 10
From here you have your equations, turn them into the f(x) form.
x + y = 16 can be turned into y = 16 - x which is f(x)=16-x
y-x = 10 can be turned into y = 10 + x which is g(x)=10 + x
Answer:
first 3plus 7 =10 then 10 y is your answer

Alexandra makes a pattern she uses 2 square for every 3 triangles in the pattern , how many triangles will Alexandra uses if the pattern has 18 square?
If the battery was used for 11 hours, then the value of x we use is 11
Subtitute x with 11 in the equation
y = 100 - 8.9x
y = 100 - 8.9(11)
y = 100 - 97.9
y = 2.1
The remaining power is 2.1%
the answer is option b
