Israel and Carlos were both eating at the same restaurant. Israel bought 4 hamburgers and 2 orders of fries for $9.74. Carlos bo

Likurg_2 [28]

Let
x-----------> cost of one hamburger
y-----------> cost of one order of fries

we know that
4x+2y=9.74--------------> equation 1
12x+y=22.77-----------> y=22.77-12x-----------> equation 2

using a graph tool---------> calculate the equations system
see the attached figure

the solution is
x=1.79
y=1.29

the cost of one hamburger is $1.79
the cost of one orders of fries is $1.29

If Tashiana buys 3 hamburgers and one order of fries
3*1.79+1.29---------> $6.66

the answer is $6.66

A, B and C are collinear and B is between A and C. The ratio of AB to AC is 1:3. If A is at (2,-6) and B is at (3,-1) what are t

Naddika [18.5K]

Answer:

(5, 9)

Step-by-step explanation:

The distance between A and B is 1/3 the distance between A and C.

x coordinates:

3 − 2 = 1/3 (x − 2)

1 = 1/3 (x − 2)

3 = x − 2

x = 5

y coordinates:

-1 − (-6) = 1/3 (y − (-6))

5 = 1/3 (y + 6)

15 = y + 6

y = 9

The coordinates of point C are (5, 9).

What's the answer? Plz explain.

Remark

Watch out for the -4<=x<=6 thing. It causes lot's of problems if you are not careful.

Solution.

The second best answer is A and if that restriction, -4<=x<=6, wasn't there, the answer would be A.

When y = - 4, the x value falls outside the restricted domain ( -4<=x<=6) we have been given. so B is not the answer.

When x = - 4 you have to read straight down to see what the y value is. It is - 2. So this is your answer. Only exactly what is the answer. They ask for the minimum value and that is a y value in this case.

So the answer is C <<<<< Answer.

When y = 1 , x = - 2 1/2. That is within the domain, but it is not the minimum value so D is wrong.

Another path in the community is 2.4 miles long. It has benches at 1/3 And 2/3 of the distance from beginning to end of the path

antoniya [11.8K]

Answer:

the benches are 0.8 and 1.6 miles from the ends of the path

Step-by-step explanation:

The first bench is 1/3 of the path's length from the beginning of the path:

(1/3)×(2.4 mi) = (2.4/3) mi = 0.8 mi

The second bench is 2/3 of the path's length from the beginning of the path:

(2/3)×(2.4 mi) = (2.4×2/3) mi = 4.8/3 mi = 1.6 mi

The benches are 0.8 mi and 1.6 mi from the beginning of the path.

_____

Of course, 0.8 mi from the beginning is 2.4-0.8 = 1.6 mi from the end, and vice-versa.
