The answer will be the set of points that contains a different x value for each point.
We clearly see that for ever point in terms of CHOICE C the value of x is different.
Answer: Choice C
Answer:
x = -1, y = 7
Step-by-step explanation:
8x + 3y = 13
3x + 2y = 11
Multiply the first equation by -2 and the second equation by 3. Then add them.
-16x - 6y = -26
(+) 9x + 6y = 33
--------------------------
-7x = 7
x = -1
Now substitute x = -1 in the first original equation and solve for y.
8x + 3y = 13
8(-1) + 3y = 13
-8 + 3y = 13
3y = 21
y = 7
Answer: x = -1, y = 7
Answer:
i believe its D
Step-by-step explanation:
D = {0,1,-1,2,-2,3,-3,4,-4,...}
<span>E = {1,2,4,9,16,25,36,49,64,81} </span>
<span>F = {12,14,16,18} </span>
<span>Finding an intersection of sets means listing the elements that are in both sets. </span>
<span>Finding a union of sets means listing all elements that are in either set. </span>
<span>With that in mind, </span>
<span>1. D intersect E = E because every element of E is a whole number, so it is in D also. </span>
<span>2. D intersect F = F because every element of F is a whole number, so it is in D also. </span>
<span>3. D intersect (E intersect F) First we find E intersect F = {16} because only 16 appears in E and F. Then, since 16 is also in D, D intersect (E intersect F) = {16} </span>
<span>4. We've already established that D contains everything in E and F. So when we take a union of (E intersect F) with D, we get all of D. </span>
<span>5. E union F = {1,4,9,12,14,16,18,25,36,49,64,81} because these are all the elements that are in either E or F. Intersecting with D doesn't change this list, since all are whole numbers.</span>
