Answer:

y = 2x + 10

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 )

Here m = 2. thus

y = 2x + c ← is the partial equation

To find c substitute (- 3, 4) into the partial equation

4 = - 6 + c ⇒ c = 4 + 6 = 10

y = 2x + 10 ← equation of line

Answer:

y = 2x+10

Step-by-step explanation:

Use formula y = mx + b, where m = slope and b = y-intercept.

For question 6 use:

m = 2

y = 4

x = -3

Plug in values:

4 = 2(-3) + b

Solve for b:

4 = -6 + b

10 = b

Write equation:

y = 2x + 10

The ratio of cassette to compact disc is 10 to 3 and the number of cassettes is 10 less than 5 times the number of compact discs

OlgaM077 [116]

There are 20 cassettes.

Step-by-step explanation:

Given,

Ratio of cassette to compact disc = 10:3

Let,

the number of cassettes = 10x

Number of compact disc = 3x

According to given statement;

the number of cassettes is 10 less than 5 times the number of compact discs.

10x = 5(Number of CD) - 10

$10x=3(5x)-10 \\10x=15x-10\\10=15x-10x\\10=5x\\5x=10$

Dividing both sides by 5

$\frac{5x}{5}=\frac{10}{5}\\x=2$

Number of cassettes= 10x = 10(2) = 20

There are 20 cassettes.

The value of x in terms of b is?

charle [14.2K]

To get x in terms of b means that we want an equation where x is alone on one side. We can do that to the given equation:
$-2(bx-5)=16$
$-2bx+10=16$
$-2bx=6$
$x=\frac{6}{-2b}$
$x=-\frac{3}{b}$
