Answer: 82
Step-by-step explanation:
We simply need to substitute the values for x and y into the equation
Both variables are already given to us, x=9, y=2
8(9)+2+4(2)
72+2+8
82
Y = ax + b;
0.89 = a * 2 + b and 2.09 = a * 5 + b =>
=> 2.09 - 0.89 = a * 5 + a * 2 + b - b => 1.20 = 3 * a => a = 1.20 / 3 => a = 0.40;
b = 0.89 - 0.40 * 2 => b = 0.89 - 0.80 => b = 0.09;
y = 0.40x + 0.09 => 0.40x - y + 0.09 = 0 is the linear equation.
Answer:
The line given is equal to y=-x+7 (Through rearranging)
To find the new line, we substitute the given coordinates (5,8) in the equation without the given y-intersect (+7):
-8=-5+c
c=-3
The line parallel to x+y=7 that passes through the point (5,-8) is y=-x-3
50% can also be written as (1/2)
Multiply the two known values:
24 x (1/2)
This is equal to (24/2). Simplify the fraction by dividing:
(24/2) = 12
