Answer:
x=-2, y=-2. (-2, -2)
Step-by-step explanation:
3x-5y=4
-5x+4y=2
-------------
5(3x-5y)=5(4)
3(-5x+4y)=3(2)
---------------------
15x-25y=20
-15x+12y=6
-------------------
-13y=26
y=26/-13
y=-2
3x-5(-2)=4
3x+10=4
3x=4-10
3x=-6
x=-6/3
x=-2
x=-2, y=-2.
The answer is 0.5. 3/(7-1) 3/6=0.5
Answer:
It has no real solutions.
Step-by-step explanation
Once you calculate the discriminant, D= (-10)^2 -4 (8)(15), you simplify the expression to get D= -380, which has no real solutions.
Answer:
<u>SOLUTION
</u>
<u>GIVEN:</u>
Two straight lines have equations y=px+4 and py=qx−7, where p and q are constants.
The two lines meet at the point (3,1)
<u />
<u>TO DETERMINE</u>
The value of q
<u>EVALUATION</u>
Here the given equation of the lines are
Now the two lines meet at the point (3,1)
Since equation (1) passes through the point (3,1)
Again Equation (2) passes through the point (3,1)
<em>FINAL ANSWER</em>
Hence the required value of q = 2
Answer:
Yes, they are proportional.
Step-by-step explanation:
The ratio for Veronica's trail mix is 3:7
The ratio for Casey's trail mix is 27:63 <--- Simplify this number
27:63 simplified is 3:7, which means <u>these ratios are proportional.</u>
<u />
hope this helps :)
