5b-b-1 > or equal too-11

Answers

Answer 1

Answer:

-2.5

Step-by-step explanation:

5b - b - 1 ≥ -11

4b - 1 ≥ -11

     +1    +1

4b ≥ -10

4/4     -10/4

b ≥ -2.5

Answer 2

Answer:

 b ≥ [tex]-\frac{5}{2}[/tex]

Step-by-step explanation:

The expression:

      5b  - b  - 1 ≥ -11

Now to solve this problem, we must be aware of some rules of inequality.

When dividing or multiplying with a negative value, the sign of the inequality must change;

         5b  - b  - 1 ≥ -11

             4b  - 1 ≥ -11

  Add + 1 to both sides;

            4b -1 + 1 ≥ -11 + 1

            4b ≥ -10

Now divided both sides by 4;

            [tex]\frac{4b}{4}[/tex] ≥ [tex]\frac{-10}{4}[/tex]  

           b ≥ [tex]-\frac{5}{2}[/tex]

5. Find the factors for the given quadratic.
x2 -21x + 20

Answers

Answer:

(x - 20)(x - 1)

Step-by-step explanation:

Given

x² - 21x + 20

Consider the factors of the constant term (+ 20) which sum to give the coefficient of the x- term (- 21)

The factors are - 20 and - 1 , since

- 20 × - 1 = + 20 and - 20 - 1 = - 21 , thus

x² - 21x + 20 =  (x - 20)(x - 1) ← in factored form

Answer:[tex](x-1)(x-20)[/tex]

Step-by-step explanation:

6 of the 10 bars are shaded, so the shaded area is 6/10 of the whole.

"Six tenths" as a decimal is 0.6, that is, a number with 6 in the tenths place.

To convert the number to a percent, multiply either the fraction or the decimal by 100%.

Find the equation of the line through point (4,−7) and parallel to y=−23x+32.

Answers

Answer:

y = -23x + 85

Step-by-step explanation:

for an equation to be parallel to another, they must have the same slope. So plugging in (4, -7) we get -7 = -23(4) + P. P being the new y intercept we must find. Now simple algebra add -23(4) = -92 to both sides and we get 85 = P. Plug in to y = mx + b and we get

y = -23x + 85

PLSSSSSS HELP ME I WILL GIVE BRAINLY

Answers

Answer: (2,2)

Step-by-step explanation:

The solution of the system of equations is the intersection point, or the point where both lines meet. Looking at the graph, we see that the blue and red line meet at (2,2). That means the solution is (2,2).

We can also solve this algebraically. Since we are given that y=x, we can plug that into the equation and solve.

y+2y=6       [combine like terms]

3y=6            [divide both sides by 3]

y=2

Since we are told that y=x, we know that x is also 2. This tells us that the solution is also (2,2).

Which pair of complex numbers has a real-number product?
* (1 + 3))(61)
* (1 + 3) (2-3)
* (1 + 3) (1-3)
* (1 + 3) (31)

Answers

Answer:

(1 + 3i)(1 - 3i)

Step-by-step explanation:

The product of a complex number and its conjugate produce a real number.

given a ± bi the conjugate is a ∓ bi ← where a and b are real, then

(a + bi)(a - bi)

= a² - b² ← a real number

The only pair of conjugate complex numbers in the list is

(1 + 3i)(1 - 3i)

The pair of complex numbers that has a real-number product is:

(1 + 3) (1-3) = -8

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

For a pair of complex numbers to have a real-number product, their imaginary parts must cancel out when the product is expanded.

Let's expand each pair of complex numbers and see which one has a

real-number product:

(1 + 3) x (61) = 61 + 183i

This product has a non-zero imaginary part, so it is not a real number.

(1 + 3) x (2-3) = -5 + 5i

This product has a non-zero imaginary part, so it is not a real number.

(1 + 3) x (1-3) = -8

This product has no imaginary part, so it is a real number.

(1 + 3) x (31) = 124 + 124i

This product has a non-zero imaginary part, so it is not a real number.

Therefore,

The pair of complex numbers that has a real-number product is:

(1 + 3) (1-3) = -8
