Answer the question
all real number
interval notation
Step-by-step explanation:
Perpendicular means "at right angles". A line meeting another at a right angle, or 90° is said to be perpendicular to it. So just to find the line segment that fits that description. Hope this helps!
Answer:
1) The solve by graphing will the preferred choice when the equation is complex to be easily solved by the other means
Example;
y = x⁵ + 4·x⁴ + 3·x³ + 2·x² + x + 3
2) Solving by substitution is suitable where we have two or more variables in two or more (equal number) of equations
2x + 6y = 16
x + y = 6
We can substitute the value of x = 6 - y, into the first equation and solve from there
3) Solving an equation be Elimination, is suitable when there are two or more equations with coefficients of the form, 2·x + 6·y = 23 and x + y = 16
Multiplying the second equation by 2 and subtracting it from the first equation as follows
2·x + 6·y - 2×(x + y) = 23 - 2 × 16
2·x - 2·x + 6·y - 2·y = 23 - 32
0 + 4·y = -9
4) An example of a linear system that can be solved by all three methods is given as follows;
2·x + 6·y = 23
x + y = 16
Step-by-step explanation:
Answer:
x=5
y=1
Step-by-step explanation:
7x+4y=39
7*5=35
4*1=4
35+4=9
2x+4y=14
2*5=10
4*1=4
10+4=14
