Tanzania [10]

Answer: unsubstantiated.

This is, the statement "Some of Tucson's residents are blue eyed children" cannot be inferred from the two original statements.

Because the subset of "Tucson's residents that have blue eyes" and the subset of "Tucson's residents that are children" might or might not have common elements.

What is the y-intercept of the following equation. 3x-2y=6

tester [92]

3x-2y=6

1) Add -3x to both sides.
 3x−2y=6
+3x +3x
-----------------
−2y=−3x+6

2) Divide both sides by -2.
 $\frac{-2y}{-2}$ = $\frac{−3x+6}{-2}$

y=32x−3

3) Substitute the y with the equation
3x-2(32x-3)=6
3x-64x+6=6

4) Combine like terms
3x-64x+6=6
-61x+6=6

5) Subtract 6 from each side of the equation
-61x+6=6
-6 -6 (+6-5 gets crossed out)
--------------
-61x=0

6) Divide both sides by -61
$\frac{-61x}{-61} = \frac{0}{-61}$
x=0

============================================================

Now that you've got you x intercept, use the x value and substitute it into the
y=32x−3

y=32(0)-3
y=0-3
y=-3

(0,-3)
