Answer:
(1, 2) is not a solution
Step-by-step explanation:
To determine if the point is a solution substitute the coordinates into the left side of both equations and if equal to the right side then the point is a solution.
- (3 × 1) - 2 = - 3 - 2 = - 5 ≠ 18
(5 × 1) + (6 × 2) = 5 + 12 = 17 ≠ - 12
Hence (1, 2) is not a solution of the system of equations
The red one is (4.1) and the green one is (-2.4) because is positive to negative so the positive side is that you got and the negative part is you owe someone for example: -20 < 30 so if it says Emily goes to the store and the milk costs $30.99 and she only has $10.00 that means that she owes $30.00 so is -10 <30
Answer: 15
Step-by-step explanation:it is 15 because the equation for area of a trapezoid is b + b x h / 2 so 12 + 3 = 15 x 2 = 30/2 = 15.
Answer:
y = -2x -12
Do you want me to explain?
Yes. 2/3 is greater than 2/5. You can check this by cross multiplication or easier just look at the denominator and numerator. In this case the numerator is the same so it's easier in a sense that you need to look at the denominator. Since the denominator 3 is close to the numerator 2 it shows that it's almost a whole unlike the other fraction. You can also convert each fraction to decimals and compare it which is also easy. Just divide the numerator by the denominator and you've got a decimal. Hope this helps!
