Step-by-step explanation:
75 x .18
tip= 13.5
75 + 13.5 = 88.5
Answer:
No real solution or if you learned imaginary numbers, 2i
Step-by-step explanation:
x^2=2x^2+4
x^2=x^2+x^2+4
Subtract x^2 from both sides
0=x^2 + 4
Subtract 4 from both sides
x^2 = -4
Square root both sides
x=sqrt(-4)
x=2i or no real solutions
Answer:
If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line.
If a system has no solution, it is said to be inconsistent .
Step-by-step explanation:
x = -7/8
y = -17/8
Proportional is the relationship two numbers share. for instance, 3 : 6. for every three, there is six. for every one, there is two.
a table would be proportional if the top numbers and the bottom numbers corresponds, such as 1 on the top and 2 on the bottom. it would continue like 2 : 4, so on and so forth.
you can tell if fractions are proportional by using cross multiplication.
