A. equation: y = -3x - 2

B. y-intercept: -2

Solution:

Given that,

Write the equation 12x = - 4y - 8 in slope-intercept form

The slope intercept form is given as:

$y = mx + c$

Where,

m is the slope and "c" is the y intercept

From given

$12x = -4y - 8\\\\Rewrite\\\\-4y-8 = 12x\\\\Move\ the\ constant\ to\ right\ side\\\\-4y = 12x + 8\\\\y = \frac{12x}{-4} + \frac{8}{-4}\\\\y = -3x -2$

Thus the slope intercept form is found

Comparing with y = mx + c ,

c = -2

Thus the y intercept is -2

Without dividing or listing multiples, how can you tell if 61 is a multiple of 6?

Slav-nsk [51]

You check if it is even and that the sum of the digits is divisible by 3. That's the divisibility rule of 6.

Given g(x) = -2x^2 + x + 6 determine: [g(x+h) - g(x)] / h

CaHeK987 [17]

Task: determine [g(x+h) - g(x)] / h

1. Starting with g(x) = -2x^2 + x + 6, determine g(x+h):

g(x+h) = -2(x+h)^2 + (x+h) + 6 = -2(x^2 + 2xh + h^2) + x + h + 6

2. Subtract g(x) from g(x+h):

g(x+h) - g(x) = -2x^2 - 4xh -2 h^2 + x + h + 6

- (2x^2 + x + 6 )

--------------------------------------------------------

= - 4xh - 2h^2 + h

3. Divide this result by h:

g(x+h) - g(x)

------------------ = -4x - 2h + 1 (answer)

Note: Soon you will begin taking the limit (as h approaches 0) of such results. Here that result would be -4x - 2(0) + 1 = -4x + 1. This algebraic quantity is the "derivative" of the given function g(x) = -2x^2 + x + 6.

A recipe for beef stew calls for 1 pound of beef and 3 potatoes the recipe is doubled to include 2 pounds of beef and 6 potatoes

Lerok [7]

Pounds of beef and potatoes are in ratio or proportion of $\frac{1}{3}$ .

Step-by-step explanation:

Correct Question: A recipe for beef stew calls for 1 pound of beef and 3 potatoes. The recipe is doubled to include 2 pounds of beef and 6 potatoes. Which proportion represents the situation?

We have , A recipe for beef stew calls for 1 pound of beef and 3 potatoes , i.e.

Number of beef stew calls = 1

Number of potatoes = 3

Now , The recipe is doubled to include 2 pounds of beef and 6 potatoes i.e. for every 2 pounds of beef we have 6 potatoes

⇒ $2/6$
