b.15×10^9
c.3.5567×10^-7
d.1×10^6
e.5.04×10^-4
f.0.05×10^-2
g.6.788432×10^8

which if the following are correctly written in scientific notation?

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

i believe that the answer is

b. y-1=-2(x-4)

hope this !
