Answer:
7) A
8) 1/2
9) 5000
Step-by-step explanation:
7)
(0, 0), (4, -10)
The line goes through point (0, 0), the origin, so its equation is of the form
y = mx, where m = slope
m = (-10 - 0)/(4 - 0) = -10/4 = -5/2
Equation: y = -5/2 x
Answer: A
8)
(0, 0), (2, 1)
The line goes through point (0, 0), the origin, so its equation is of the form
y = mx, where m = slope
m = (1 - 0)/(2 - 0) = 1/2
Equation: y = 1/2 x
Answer: 1/2
9)
The value of the house increases $5000 per year, so we multiply the number of years, x, by 5000 to find the increase after x years.
Equation: y = 5000x
Answer: 5000

You have to collect like terms and simplify
Answer:
What even is this???
Step-by-step explanation:
....
If a line <span>parallel </span>to one side of a <span>triangle </span>intersects the other two sides of the triangle, then the line divides these two sides proportionally.
When simplifying the following expression we want to look first at adding like terms to together
2x² - 5x² = -3x²
Once the squared exponents are added together add the x’s together:
x + 7x + 7x = 15x
Now add the integers together:
1 + 5 + (-4) = 2
Since you can’t add exponents with each other unless the have the same exponent they stay the same:
The equation should look like this:
-3x² + 15x + 2 -3x²³
Now add the exponents together because it is exponents of x.
-6x^25 + 15x + 2
That is the most simplified version of the complex equation.
