C. (8,-2), (-2,5), (6,0) is a function, because all the numbers are different unlike A, B, and D those all have the same number either in there domain or range.

3. The talent show committee sold a total of 522 tickets. Student tickets cost $3 each and adult tickets

irina1246 [14]

Answer:

Step-by-step explanation:

If student ticket = 215 then 215 x 3 = 645$

Remaining tickets = 522 - 215 = 307

So adult tickets = 307 x 4 = 1228$

Total amount = 1228 + 645 = $1873

Write the expression (4x-2)×6(2x+7) in the standard form of a quadratic expression ax^{2}+bx+c. What are the values of the coeff

lesya [120]

(4x-2)×6(2x+7) =

(4x-2) × 12x + 42 =

48x^2 -24x + 168x -84 = 0

48x^2 +144x -84 = 0

a = 48 b = 144 and c = -84
and the solution is
x1=.5 and x2=-3.5

(80pts) The ratio of the number of A's in the class to B's in the class was 2:5. How many people got A's if there were 40 people

allsm [11]

Make a proportion using the ratio (A:B) given and number of As and Bs really gotten in the class ( $\frac{A's}{B's}$ )

$\frac{2}{5} = \frac{A}{40}$

Cross multiply

2 * 40 = 5 * A

80 = 5A

Isolate A by dividing 5 to both sides

80/5 = 5A/5

16 = A

If 40 people in the class got B's then 16 people got A's

Hope this helped!
