The second one might be the answer
Answer:
infinitely many solutions
Step-by-step explanation:
Let's first eliminate y^2.
To accomplish this, divide the 2nd equation by 5, obtaining
y^2 = 5/2 - x^2. Now substitute this result for y in the first equation:
(-1/3)x^2 = -5/6 + (1/3)(5/2 - x^2), or
-x^2 -5 5 x^2
-------- = ------ + ------- - -------- and this simplifies to:
3 6 6 3
-x^2 x^2
------- = - ------- which is an identity and is thus always true.
3 3
Thus, any value of x will satisfy this equation; there are infinitely many solutions.
Answer:
x = 4
Step-by-step explanation:
<u>All triangles add up to 180 degrees</u>
76 + 17x + 9x = 180
76 + 17x + 9x - 76 = 180 - 76
26x / 26 = 104 / 26
x = 4
Answer: x = 4
Answer:
(D) "...because he will not have to pay any interest on his purchases during the introductory APR period."
Step-by-step explanation:
There may be many reasons for John to choose one over the other depending on his future and planned usage patterns. However, answer the (D) is the only correct one in terms of stating a reason that is actually supported by the information in the question. Specifically, there is 0% APR for card B.
What's wrong with the other choices:
Choice A: incorrect statement re APR after intro period (is not 1%); B: incorrect statement re cash advance (is not 0%); C: statement is not supported by anything in the information given (it is an assumption, and is unlikely).
Answer:
y = x + 3
Step-by-step explanation:
I'm assuming that you are asking for a line perpendicular to
3x + 3y = 3 and going through (-1, 2)
first find the slope of the line
3y = -3x + 3
y = -1x + 1, the slope is -1 so the perpendicular slope is 1
y = mx + b
2 = 1(-1) + b
3 = b
y = x + 3
