is 1/2 and 4/9 proportional
Answer:
No
Step-by-step explanation: If right press thanks and rate 5/5 plz
Answer:
Not proportional.
Step-by-step explanation:
To find out if the fractions are proportional, you have to cross multiply each fraction to see if each number multiplied is the same. 2 * 4 = 8 and 1 * 9 = 9. The numbers are not the same here so it is not proportional.

Given the linear equation Ax+By=8,it's x intercept is (8,0) and y-intercept is (0,8). What are the values of a and b
Answer:
A=1, B=1
Step-by-step explanation:
Equation of the line in intercept form
The intercept form of the equation of a line is:
[tex]\displaystyle \frac{x}{h}+\frac{y}{k}=1[/tex]
Where:
h = x-intercept
k = y-intercept
We are given the y-intercept (0,8) and x-intercept (8,0), thus the equation is:
[tex]\displaystyle \frac{x}{8}+\frac{y}{8}=1[/tex]
Multiplying by 8:
x + y = 8
Thus, the values of A and B are:
A=1, B=1

Answer:
x = 133.33°
Step-by-step explanation:
The Law of Cosines
It relates the length of the sides of a triangle with one of its internal angles.
Let a,b, and c be the length of the sides of a given triangle, and x the included angle between sides a and b, then the following relation applies:
[tex]c^2=a^2+b^2-2ab\cos x[/tex]
Since we know the values of all three side lengths, we solve the equation for x:
[tex]\displaystyle \cos x=\frac{a^2+b^2-c^2}{2ab}[/tex]
For the triangle in the figure: a=4.1, b=8.5, c=11.7, x=angle C. Applying the formula:
[tex]\displaystyle \cos x=\frac{4.1^2+8.5^2-11.7^2}{2*4.1*8.5}[/tex]
[tex]\displaystyle \cos x=\frac{-47.83}{69.7}[/tex]
[tex]\displaystyle \cos x=-0.6862[/tex]
[tex]x = \arccos (-0.6862)[/tex]
x = 133.33°

2y + 4x = 16
Anyone know how to solve for Y?
Answer:
y = -2x + 8
Step-by-step explanation:
In this question, you have to solve for "y".
Solve:
2y + 4x = 16
Get "y" by itself by subtracting 4x from both sides.
2y = -4x + 16
Simplify by dividing both sides by 2.
y = -2x + 8
