Answer:
y-8=-3/2(x+8)
Step-by-step explanation:
y-y1=m(x-x1)
y-8=-3/2(x-(-8))
y-8=-3/2(x+8)
Answer:
2 weeks
Step-by-step explanation:
Given in the question that,
Equation that represent Lisa's total amount of money
f(x) = 20 - 13x
Equation that represent Joey's total amount of money
g(x) = x² - 10
To find weeks, x, after which they will have same amount of money, we will equate both equation
<h3>20 - 13x = x² - 10</h3>
x² - 10 - 20 + 13x = 0
x² - 30 + 13x = 0
x² + 13x - 30 = 0
(x - 2)(x + 15) = 0
x = 2 or x = -15
Weeks, x, can not be negative so we will reject x = -15
Hence, after 2nd week Lisa and Joey will have the same amount of money save.
Answer:
Step-by-step explanation:
(a - b)² = a² - 2ab +b²
Area of rectangle = length * width
= (2x - 5)(2x -5)
= (2x - 5)²
= (2x)² - 2*(2x)(5) + 5²
= 4x² - 20x + 25
