1. {2x−3y=9
{3x+5y=4
2. {(2x−3y=9)×5
{(3x+5y=4)x3
3. {10x-15y=45
{9x+15y=12
4. (10x-15y=45) + (9x+15y=12)= (19x=57)
5. (19x=57)÷19
6. x=3
7. 2(3)-3y=9
8. 6-3y=9
9. -3y=9-6
10. (-3y=3)÷(-3)
11. y=-1
Answer: x=3 and y=-1
Answer:
a, d, e, g
I don't know if it's right :(
this was last year for me :(
Answer:
R(-2,0)
S(0,-4)
T(-4,-3)
Step-by-step explanation:
So first you gotta subtract 2 from each x value and 1 from each y value. After you do that, you get:
R(0,2)
S(-4,0)
T(-3,4)
then i put it all onto a graph, and rotated it 90* counterclockwise, from the origin, which puts it in quadrant 3, with the final coordinates above.
15.87% of the population does not meet the minimum standards.
We use z-scores to find this probability:
z=(X-μ)/σ = (85-100)/15 = -15/15 = -1
Using a z-table (http://www.-table.com) we see that the area to the left of, less than, this is 0.1587. This is 15.87%.
