Step-by-step explanation:
add up both equations
2x -y + 3x + y -13 = 0 (y will eliminate -y)
5x -13 = 0
5x = 13
x = 13/5 now use this value to find y
2 × 13/5 -y - 4 = 0
26/5 - y -4 = 0
26/5 - 4 = y
6/5 = y
Answer:
y = 3
Step-by-step explanation:
y = k/x
xy = k
3 × 8 = k
k = 24
x = 8
y = 24/x
y = 24/8
y = 3
First off, we'll move the non-repeating part in the decimal to the left-side, by doing a division by a power of 10.
then we'll equate the value to some variable, and move the repeating part over to the left as well.
anyhow, the idea being, we can just use that variable, say "x" for the repeating bit, let's proceed,
and you can check that in your calculator.
Answer:
3 x^2 (x + 3)
Step-by-step explanation:
Factor the following:
3 x^3 + 9 x^2
Factor 3 x^2 out of 3 x^3 + 9 x^2:
Answer: 3 x^2 (x + 3)
Today I am going to share with you my ideas about my favourite time of the day. All time is great. It is God's gift to us to make or mar ourselves. I respect time whether in the morning, afternoon, evening, or night; I just love time.
