X-3y=9
-3y=-x+9
Divide by -3
Y=1/3x+3
Slope is 1/3x
Y intercept is 3
X intercept is 9
Answer:
The two number are :
x = 1411
y = 1079
Step-by-step explanation:
Let the two numbers = x and y
The sum of two numbers is 2490
x + y = 2490..... Equation 1
If 6.5 percent of one no. is equal to 8.5 percent of the other,
Hence:
6.5% of x = 8.5% of y
0.065x = 0.085y
Make x the subject of the Formula
x = 0.085y/0.065
x = 1.308y
We substitute 1.308y for x Equation 1
x + y = 2490..... Equation 1
1.308y + y = 2490
2.308y = 2490
y = 2490/2.308
y = 1078.8561525
y = 1079
x + y = 2490..... Equation 1
x = 2490 - y
x = 2490 - 1079
x = 1411
Answer:
1/10

Answer:
6.1
Step-by-step explanation:
If we are rounding at the 0 digit, we look at the next digit, which is 9
9 >= 5 so we need to round the 0 up to 1
6.099 rounds to 6.1
Using the cosine rule, a² = b² + c² -2 bc cos θSImplifying the equation in terms of cos theta,
cos(θ) = (a² + c² - b²)/(2bc)
(a² + c² - b²)/(2bc) > 0 a² + c² - b² > 0
assuming b and c are non zeros, the resulting inequality should be
a² + c² > b²
THe appicable inequality is a
