Given that a = -1, b=2 and c= -3 ,find the value of a(b2+c2)

a(+) = = -13

Step-by-step explanation:

Given that a = -1, b=2 and c= -3

find the value of a(+)

Just substitute the values given for each variable

a(+) = (-1)(+) ; do the exponents first

a(+) = (-1)(4+9)=(-1)(13) ; now add inside the parenthesis;

a(+) = -13 ; and multiply by -1

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
