7/1 x 3/14 = 21/14 = 3/2 = 1 1/2
The answer is 1 1/12 or 1.5, but I recommend the fraction way since the problem was in fractions!
Step-by-step explanation:
x² - 2x - 15 = 0
x1 = 5
x2 = -3
3x + 2y = 39
5x - y = 13
Multiplying the last by two:
10x - 2y = 26
Adding to the first
13x = 65
x = 5
y = 5x-13 =25-13=12
Check:
3(5)+2(12)=39 good
5(5)-12=13 good
Answer: x=5, y=12
Answer:
10
Step-by-step explanation:
isolate y by adding 5 to each side. Now you have y=x+10. 10 is the c value, which is the y-intercept
