Answer: b=1/36

Step-by-step explanation:

15 - 1/2b = -3

subtract 15 from both sides

-1/2b = -18

multiply both sides by 2b

-1 = -18(2b)

-1 = -36b

divide both sides by -36

-1/-36 = b

b = 1/36

How many solutions can be found for the linear equation? 4(x + 5) - 5 = 8x + 18/ 2
mylen [45]

Answer: The correct option is A.

Explanation:

The given equation is,

4(x+5)-5=\frac{8x+18}{2}

Multiply both sides by 2.

2[4(x+5)-5]=\frac{8x+18}{2}

8(x+5)+2(-5)=8x+18

8x+40-10=8x+18

8x+30=8x+18

Subtract both sides by 8x.

30=18

This statement is false for any value of x, therefore the system of equation have no solution and option A is correct.

Mathematics Slope Mh
masya89 [10]

Answer:

y = - 2x - 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, - 2) and (x₂, y₂ ) = (1, - 8)

m = \frac{-8+2}{1+2} = \frac{-6}{3} = - 2, thus

y = - 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 2, - 2), then

- 2 = 4 + c ⇒ c = - 2 - 4 = - 6

y = - 2x - 6 ← equation of line

Write an algebraic expression to represent the verbal expression
MakcuM [25]
You set it up like this.

It says "the difference", so you put a minus sign: -
It says that the minuend, or the part being taken away from is a quantity equal to the product of 4 and "some number" (we'll use x), so now you have: (4 * x) -
Next, it says the subtrahend, or part being removed, is the square of "the number", meaning we use the "some number", x, from before, so now you have: (4 * x) - x^2
