I presume that the answer is option a, but it is incorrect. The right answer should be < 47, - 61, 17 >; yes, and for clarification, take a look at the attachment below -
As written here, both choices B and C represent proportional relationships:
... B. y = 12x
... C. y = 3x
_____
One key to a proportional relationship is that when one variable is zero, so is the other. This will not be the case for selections A and D.
If x equals -13 then..
-4(-13)+5y=12
52+5y=12
5y=-40
y=-8
Answer:
29
Step-by-step explanation:
Let c, r, g stand for the current ages of Carolina, Raul, and Ginny. Then we have the relations ...
c = 2r
g = 3r +4
c + r + g = 52
Substituting for c and g, we get ...
2r + r + (3r +4) = 52
6r = 48 . . . . . . . . . . . . . subtract 4
r = 8 . . . . . . . . . . . . . . . divide by 8
g = 3(8) +4 = 28 . . . . . .Ginny is presently 28
On Ginny's next birthday, she will be 29.
