IF YOU KNOW SPANISH AND ALGEBRA PLEASE HELP

See below for answers and explanations

Step-by-step explanation:

Part A:

f(x) = -x² + 4x - 10

f(2) = -(2)² + 4(2) - 10

f(2) = -4 + 8 - 10

f(2) = 4 - 10

f(2) = -6

Part B:

g(x) = 5x + 1

g(6) = 5(6) + 1

g(6) = 30 + 1

g(6) = 31

Part C:

f(x) = -x² + 4x - 10

f(-1) = -(-1)² + 4(-1) - 10

f(-1) = -1 - 4 - 10

f(-1) = -5 - 10

f(-1) = -15

Part D:

g(x) = 5x + 1

16 = 5x + 1

15 = 5x

3 = x

x = 3

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
