Answer:

b/4 = 2

b/4 = 2/1

Then cross multiply to get this;

b = 4×2

b = 8

Thank you.

Answer: b = 8

Step by step explanation :

Step 1 : Multiply by 4 on both sides of the equation.
B/4 times 4 = 2 times 4
Multiplying by 4 and dividing by 4 cancel each other out, so we’re left with b = 2 times 4, or b = 8.

Solve for x. Show or explain your work.

belka [17]

Answer:

-8 = x

Step-by-step explanation:

-15 = 2x + 1

-1 - 1 Subtract 1 from both sides

-16 = 2x Divide both sides by 2

-8 = x

To make sure this answer is correct, plug it into the equation to see if it works.

-15 = 2(-8) + 1 Multiply

-15 = -16 + 1 Add

-15 = -15

Arrange the functions in ascending order, starting with the function that eventually has th least value and ending with the func

WINSTONCH [101]

Answer:

$3x,3x+8,x^{2} ,x^{2}+6,4^{x} ,4^{x}+3,$

Step-by-step explanation:

We have to arrange the functions given in ascending order which have eventually the least value and eventually the greatest value.

So, we get the following table representing the values of the functions for different values of x.

x : 5 10 15

$y_{1} =3x+8$ : 23 38 53

$y_{2} =4^{x} +3$ : 1027 1048579 1073741827

$y_{3} =x^{2} +6$ : 31 106 231

$y_{4} =3x$ : 15 30 45

$y_{5} =4^{x}$ : 1024 1048576 1073741824

$y_{6} =x^{2}$ : 25 100 225

As, can be seen from the table that the ascending order of the functions is given by $y_{4},y_{1},y_{6},y_{3},y_{5},y_{2},$ .

Hence, the order is $3x,3x+8,x^{2} ,x^{2}+6,4^{x} ,4^{x}+3,$ .

What is the equation of a line that passes through the point (5, −4) and is parallel to the line whose equation is 2x + 5y = 10?

dybincka [34]

What you should do first is simplify the equation into the y = mx + b format. Move 2x to the other side. Know that in doing this, 2x must become the opposite of what it currently is (-2) in order for the equation to remain true. We also have to take away the '10' because the line is parallel, not exactly the same, which means a different y intercept. This looks like:

$5y = -2x + b$

Next, simplify y to make things easier. This can be done by dividing both sides by 5, like so:

$\frac{5}{5}y = -\frac{2}{5}x + b$

What you should also know is that if a line is parallel to another, then this means the slope has to be the same because they both have the same changes in rise and run. With this in mind, simply plug in the x and y values.

$(-4) = -\frac{2}{5} * (5) + b$
