Answer:
<h2>x = 0 or x = 1 or x = 2</h2>
Step-by-step explanation:
<em>The product is 0 if one of the factors is 0.</em>
<span>we count parts
10 meat
9 rice
5 vegetables
sum 10 + 9 + 5 = 24 parts
10/24 meat
9/24 rice
5/24 vegetables
</span><span>Prices determine multiplying 60,000 by a fixed value of the fraction
</span><span>
60.000 *10/24 = 600 000/24 = 25 000 meat
60 000 * 9/24 = 540 000/24 = 22 500 rice
60 000 * 5 = 300 000/24 = 12 500 vegetables
check 25 000 + 22 500 + 12 500 = 60 000
</span>
Take the fouth square root of both sides
![\sqrt[4]{{x}^{4} } = \sqrt[4]{24}](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B%7Bx%7D%5E%7B4%7D%20%7D%20%20%3D%20%20%5Csqrt%5B4%5D%7B24%7D%20)
so
![x = \sqrt[4]{24} \: or \: x = - \sqrt[4]{24}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Csqrt%5B4%5D%7B24%7D%20%20%5C%3A%20or%20%5C%3A%20%20x%20%3D%20%20-%20%20%5Csqrt%5B4%5D%7B24%7D%20)
Answer:
y = -2x + 9
Step-by-step explanation:
The slope of the line can be found from 2 points.
(y2-y1)/(x2-x1)
7-3/1-3
4/-2
= -2
-2 is the slope.
The y-intercept is 9.
The equation of a line is y=mx+b.
m is the slope, and b is the y-intercept.
y = -2x + 9
