Evaluate a-b²c2 for a = 2, b = 3, and c = 4.

-70

Step-by-step explanation:

1. Write out equation : 2-3^2(4)(2)

2. PEMDAS = (Exponents) 3 to the second power = 9

3. 2-9(4)(2)

4. Multiply 9 & 4 which is 36 then multiply

36 & 2 which is 72

5. 2-72

6. -70

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
