Answer:

This is a function

Step-by-step explanation:

If you do the Vertical Line Test you can see that the line passes through only one dot at a time. Therefore it is a function. If the line passed through more than one dot at a time then it wouldn't be a function.

Matt and Mark went to El Rodeo to have some dinner. Matt ordered 3 tacos and 2 enchiladas, which cost him $4.93. Mark ordered 2

lord [1]

Answer:

The cost of one taco is $0.87 and the cost of one enchilada is $1.16

Step-by-step explanation:

Let the cost of tacos be X

and cost of enchiladas be y

So, by using given data, we have following equations

3X + 2Y = 4.93 (1)

2X + 4Y = 6.38 (2)

So, first multiply 1st equation by 2 and 2nd equation by 3, then subtracting 1st equation by 2nd.

= 2 × ( 3X + 2Y = 4.93) (1)

= 3 × (2X + 4Y = 6.38) (2)

= - (6X + 4Y = 9.86) (1)

= 6X + 12y = 19.14 (2)

= 8Y = 9.28

Y = 9.28 ÷ 8 = 1.16

By putting the value of Y in equation 1, we get

3X + 2(1.16) = 4.93

3X + 2.32 = 4.93

X = 2.61 ÷ 3 = 0.87

Hence, the cost of one taco is $0.87 and the cost of one enchilada is $1.16.

What is the area of a rectangle that has side lengths of 3/4 yard and 5/6 yard

Ahat [919]

We are asked to find the area of the rectangle that has side lengths of 3/4 yard and 5/6 yard.

We know that area of rectangle is width times length.

To find the area of the given rectangle we will multiply both side lengths as:

$\text{Area of rectangle}=\text{Width}\times \text{Length}$

$\text{Area of rectangle}=\frac{3}{4}\text{ yard}\times\frac{5}{6}\text{ yard}$

$\text{Area of rectangle}=\frac{3}{4}\times\frac{5}{6}\text{ yard}^2$

$\text{Area of rectangle}=\frac{1}{4}\times\frac{5}{2}\text{ yard}^2$

$\text{Area of rectangle}=\frac{1\times5}{4\times2}\text{ yard}^2$

$\text{Area of rectangle}=\frac{5}{8}\text{ yard}^2$

Therefore, the area of the given rectangle would be $\frac{5}{8}$ square yards.
