2 answers:

8 0

Y = (X+4)^2
Y = (X+4)(X+4)
X intercept = y = 0
0 = (X+4)(X+4)

(X+4)=0
X = -4.
X intercept = (-4,0).
Then you would plot this X intercept on the graph of the parabola.

How do you determine what your grade average is based on the following grades?:

fiasKO [112]

Answer:

Test's average-95

Homework's average-96.67

Step-by-step explanation:

Average is mathematically defined as the sum of the values divided by the total number of values and is expressed as:

$\bar X=\frac{1}{n}\sum{x_i}, n=number \ of \ values.$

The Tests' average is calculated as:

$\bar X_t=\frac{1}{n}\sum{x_i}\\\\=\frac{1}{3}(98+92+95)\\\\=\frac{1}{3}\times 285\\\\=95$

Hence, the Tests' average is 95

#The Homework's average is calculated as:

$\bar X_h=\frac{1}{n}\sum{x_i}\\\\=\frac{1}{3}(93+97+100)\\\\=\frac{1}{3}\times 290\\\\=96.67$

Hence, the Homework's average is 96.67

A car salesman makes 10% commission on the first $ 10,000 and 12% on the remaining the 12,500 of his sales. How much commission

marissa [1.9K]

10,000 x .10 = $1000
22500-10000=12500 x .12 = $1500
$1000 + $1500 = $2500
