Answer:

y=2/3x-8

Step-by-step explanation:

The y-intercept is 8 because (0,8) and if you do rise/run for the slope you get 2/3. 0-(-4)/(12-6)=4/6=2/3

Edit:

I just graphed the points you had and then used the slope to go backwards. So I did (-4,6) and went down 2 and left 3 (from the 2/3 slope rise/run), that gives you (-6, 3) and then I did it again I went down 2 and left 3 which gives you (-8,0). The y intercept is where x=0 so then it would be y=-8 as the y-intercept. To find the slope you just subtract the y-values (6-0) for the last 2 and put that answer (6) over the run which you get from subtracting the x values (21-12) again for the last two. That gives you 9 so it is 6/9. If you simply that you get 2/3 because 6/3=2 and 9/3=3. So you divide the top and bottom of 6/9 by 3 to get 2/3 for the slope. I gave the equation in slope-intercept form which is y=mx+b and m=slope, b=y-intercept. Let me know if it still doesn't make sense i don't know how to say it and it won't let me comment

The length of a rectangle is 4 inches more than its width, and its perimeter is 34 inches. Find the length and width of the

gizmo_the_mogwai [7]

Answer:

Width = 6.5 inches

Length = 10.5 inches

Step-by-step explanation:

Let

"l" be length of rectangle

and

"w" be width of rectangle

Since length of rectangle is 4 inches MORE THAN WIDTH, we can write:

l = 4 + w

The perimeter is sum of all sides, so

Perimeter = l + l + w + w = 2l + 2w

The perimeter is 34, so we can write:

2l + 2w = 34

Putting 1st equation in 2nd, we get equation in "w" and solve for this first:

$2l + 2w = 34\\2(4+w) + 2w = 34\\8+2w+2w=34\\4w=26\\w=\frac{26}{4}=6.5$

Width is 6.5 in

Now, l = 4 + w, so

l = 4 + 6.5 = 10.5

Length is 10.5 in

In order to develop a more appealing cheeseburger, a franchise used taste tests with 13 different buns, 5 different cheeses, 2 t

JulsSmile [24]

Answer:

<h3>If the taste tester takes 10 minutes to eat a cheeseburger, then it would take him is $3276\times 10 = 32760$ minutes Eating round the clock, it would take him is $\frac{546}{24} = 22 days 18 hours$ </h3>

Step-by-step explanation:

Given that "In order to develop a more appealing cheeseburger, a franchise used taste tests with 13 different buns, 5 different cheeses, 2 type of lettuce, and 3 types of tomatoes"

From the given we can write

13 buns

8 cheese

4 lettuces

3 tomatoes

∴ There would be different cheeseburger combinations is given by

$13\times 8\times 4\times 3 = 3,276$

Given that if the taste tester takes 10 minutes to eat a cheeseburger, then it would take him

$3276\times 10 = 32760$ minutes

Eating round the clock, it would take him

$\frac{32760}{60}=546$ hours

$\frac{546}{24} = 22 days 18 hours$
