Answer:
B (-9,−57/8)
Step-by-step explanation:
we know that
If a ordered pair is a solution of the linear equation, then the ordered pair must satisfy the linear equation
we have
<u><em>Verify each case</em></u>
Substitute the value of x and the value of y in the linear equation and then compare the results
case A) (6,17/2)
For x=6, y=17/2
Substitute
-----> is not true
therefore
The ordered pair not satisfy the equation
case B) (-9,-57/8)
For x=-9, y=-57/8
Substitute
-----> is true
therefore
The ordered pair satisfy the equation
case C) (6,-39/8)
For x=6, y=-39/8
Substitute
-----> is not true
therefore
The ordered pair not satisfy the equation
case D) (6,-8)
For x=6, y=-8
Substitute
-----> is not true
therefore
The ordered pair not satisfy the equation
I would love to help you but there is no way to do a midpoint on brainly,
Answer:
Step-by-step explanation:
This is a straight proportion problem.
15/42 = x/140 Cross Multiply
15*140 = 42 * x
2100 = 42x Divide by 42
2100/42 = x
x = 50 ml of HCl will be needed.
