b^2 + 5b - 5

= -6^2 + 5(-6) - 5

= -36 + (-30) - 5

= -66 - 5

Therefore, your answer is: -71

Good luck on your assignment and enjoy your day!

If twice a number is at least three less than four times the number, which of the following are true? Let n represent the number
NikAS [45]

Answer:


Step-by-step explanation:

Let n represent the number

Twice the number =2n


4 times the number = 4n


Given that twice the number is atleast 3 less than four times the number


Algebraically this can be written as


2n≤4n-3


We can add 3 to both sides


So n should be atleast 1.5


If n is natural number or integer then least value of n is 2.

viktelen [127]
3x = 4y
X+y = 21

Multiply second equation by 3

3x+3y= 63

Substitute 3x with 4y

4y + y = 21

5y = 21

Y=4.2

X + 4.2 = 21

x= 16.8
