Find the x- and y- intercepts of the following equation.
Ivanshal [37]

Answer:

The x-intercept is (4,0)

The y-intercept is (0,-3)

Step-by-step explanation:

Suppose you have a function f:

f = f(x,y) = 0

The x-intercept is the value of x when y = 0.

The x-intercept is the value of y when x = 0.

Solution

We have:

f(x,y) = -3x + 4y = -12

-3x + 4y + 12 = 0

x-intercept

The x-intercept is the value of x when y = 0. So:

-3x + 4(0) + 12 = 0

-3x + 12 = 0*(-1)

3x - 12 = 0

3x = 12

x = \frac{12}{3}

x = 4

The x-intercept is (4,0)

y-intercept

The y-intercept is the value of y when x = 0. So:

-3(0) + 4y + 12 = 0

4y + 12 = 0

4y = -12

y = \frac{-12}{4}

y = -3

The y-intercept is (0,-3)

How many quarter pound burgers can george make out of 3 1/2 pounds of ground beef ?
lana [24]
Assuming that there is no wastage of beef. 

Note that 3 1/2 = 7/2 = 14/4 = 14 * 1/4 
This means that we can have 14 sets of quarter pound beef. 

This in turn means that George can make 14 quarter pound burgers.

Grace rolls a fair, 6-sided die 50 times.
Lostsunrise [7]

Answer:

Step-by-step explanation:

Here's the thing. It is easier to figure out the probability of not getting a six even once during the 50 rolls.

The chance of that happening is (5/6)^50 = 0.00010988

So the probability is succeeding is (1 - 0.00010988) = 0.9999 rounded to 4 places.
