F: b^2
O: -9b
I: +3b
L: -27

so
b^2 -9b +3b -27
=b^2 -6b -27

answer b^2 -6b -27 (last choice)

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify

Point (-1, -3.75)

Point (-1, 4.5)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-1--1)^2+(4.5--3.75)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(0)^2+(8.25)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{0+68.0625}$
[√Radical] Add: $\displaystyle d = \sqrt{68.0625}$
[√Radical] Evaluate: $\displaystyle d = 8.25$

All 28 members in Crestview High School’s Ski Club went on a one-day ski trip. Members can rent skis for $16.00 per day or snowb

antoniya [11.8K]

The way I would approach such a question is to put it into equations. My first equation would be 16x+19y=478 which represents $16 on ski's per person and $19 on snowboards must add up to $478 My second would be x+y=28 because the number of skis and snowboards rented must add up to 28 so each person has one item. Next you solve them simultaniously. Gonna use elimination

16x+19y=478 (1)

x+y=28 (2)

16x+16y=448 (3 = equation 2 * 16) (1)-(3) => 3y=30 y = 10. So now we know that 10 people rented snow boards. Just sub that into eq (2) and get x = 18. So 10 people got snow boards and 18 ski's.

To check, 10x19 = 190 16x18= 228

190+228=478 which works out perfectly!

Graph this function using intercepts: 27x–15y=1,350. Provide x and y intercepts

yanalaym [24]

Answer:

graph attached

Step-by-step explanation:

27x - 15y = 1350

15y = 27x -1350

y = 27/15 x - 1350/15

y = 9/5 x - 90

y = mx + b y intercept (b) = -90

y=0 x = 90 * 5/9 = 50 x intercept
