9 = -7 + 8x
add 7
16 = 8x
x = 2
Step-by-step explanation:
Beef = 12 * 8 (cause 25 * 8 = 200)
Beef = 96
Chicken = 8 * 8 (cause 25 * 8 = 200)
Chicken = 64
Pasta = 5 * 8 (cause 25 * 8 = 200)
Pasta = 40
Answer- C] There are 32 more students who want beef meal more than want a chicken meal
X² + mx + m A perfect square trinomial is where:x² - is the square of the first term binomialmx - is twice the product of the binomials first and last termm - is the square of the last term binomial
x² + mx + m = (x + 1)²
(x + 1)² ⇒ (x+1)(x+1) = x(x+1) +1(x+1) ⇒ x² + x + x +1 = x² + 2x + 1
Answer:
The answer is 48600, but I'm not entirely sure if it correct.
From what I know, if I were to see ¨y=7500(1.08)t¨, we could have to substitute the t with the number of years. Looking like this, ¨y=7500(1.08) x 6¨.
The reason I don know if my answer is correct or not since I don know if you have the t next to 1.08 to represent that or to simply multiply the property of it with 6 (the number of years).
So I tried...

Answer:
2401
Step-by-step explanation:
Given that we want to estimate average income in a population.
The standard deviation of income in the population is $1,000
We want confidence interval around our estimate to be +/- $40
i.e Margin of error = 40
We know that margin of error = Std error * Z critical for 95%
i.e. 
Std error = 
Together we get
