Which choices are correctly written in scientific notation? Check all that apply 17.1 times 10 Superscript 3 8.05 times 10 Superscript 3 6.25 times 4 Superscript 3 4 times 10 Superscript negative 16 22.09 times 10 Superscript negative 9 3.03 times 10 Superscript negative 1 5 times 10 Superscript 10 3.44 times 1 Superscript 10

i would say c is the best answer, hope it's right!

good luck! =)

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
