You can use Guess and Check and divide the 50 pounds into 2 parts. Multiply the price for both and do square root for the prices. Then at the 2 square roots and see if they add up to $6.40. If not, then divide the 50 pounds into something else, like 30 and 20 or something like that.
In 1 year, it erodes 2 5/18
In 8 years, it will erode: 8*2 5/18= 41/9
Answer= 41/9 = 4 5/9
Her insurance premiums are 150 per month.....there is 12 months in a year....so in 1 year, her premiums totaled : (150 * 12) = 1800
she paid a $ 500 deductible
she paid 20% of $ 3000 for the accident..
0.20 * 3000 = $ 600
therefore, her total healthcare expenses for 1 yr totaled :
1800 + 500 + 600 = $ 2900 <==
Answer:
I’m not sure
Step-by-step explanation:
Answer:
f(x) = (x + 4)² - 3
Step-by-step explanation:
The equation of a quadratic function in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = x² + 8x + 13
To obtain f(x) in vertex form use the method of completing the square
add/ subtract (half the coefficient of the x- term)² to x² + 8x
f(x) = x² + 2(4)x + 16 - 16 + 13
f(x) = (x + 4)² - 3 ← in vertex form
