I’m not the best at graphs but i did take algebra, i think it’s graph number 2. also i’m sorry if it’s wrong:(
Answer:
x1 = -3 x2 = 3
Step-by-step explanation:
(0, -2) and (1, 1) both work in this system of equations.
The best way to find if it is a solution is to look for those points on the graph. When you graph the point, it needs to fall in an area where both lines or shaded or on a solid line.
(0, -2) falls on a solid line.
(1, 1) falls in the double shaded area.
Step-by-step explanation:
9x+4=15
9x=15-4
9x=11
x=11/9 or 1 2/9
Answer:
Error was CHOOSING the CORRECT hypotenuse in the given sides.
H = 41 units
Step-by-step explanation:
Here, the given sides of the triangle are: 41,40 and 9
Now, as we know in a RIGHT ANGLED TRIANGLE:
The longest side is the HYPOTENUSE.
So, here H = 41
Now, by PYTHAGORAS THEOREM:


Hence, Pythagoras theorem for Right angled triangle is SATISFIED
So, error was CHOOSING the CORRECT hypotenuse in the given sides.
The correct H = 41 units and NOT 40 units.
