Answer:

y=1, so (0, 1)

Step-by-step explanation:

Just subtract 3 from -2. Since there is no x in the problem, it means that this line is horizontal, meaning that the x can change but the y has to stay at 1.

The line is horizontal so there is no vertex point

Five cupcakes and two cookies cost $19.75. Two cupcakes and four cookies cost $ 17.50.

alina1380 [7]

Answer:

Step-by-step explanation:

Let x and y represent the cost of a cupcake and cookie respectively.

Given that;

Five cupcakes and two cookies cost $19.75.

$5x+2y=19.75 ---------- 1$

Two cupcakes and four cookies cost $17.50.

$2x+4y=17.50 --------------2$

Let's solve the simultaneous equation by elimination;

Multiply equation 1 by 2;

$10x+4y=39.50-------3\\$

Subtract equation 2 from equation 3;

$10x-2x+4y-4y=39.50-8x=22$

$8x=22$

divide both sides by 8

$\frac{8x}{8} =\frac{22}{8} \\x=2.75$

Since we have the value of x, let substitute into equation 1 to get y;

$5x+2y=19.75\\5(2.75)+2y=19.75\\13.75+2y=19.75\\2y=19.75-13.75\\2y=6\\y=\frac{6}{2} \\y=3.00$

therefore , the cost of cupcakes and cookies are;

$cupcakes= 2.75\\cookies= 3.00$

The perimeter of quadrilateral JKLM is 90 centimeters. Which is the length of side KL?

fenix001 [56]

The perimeter of an object is given by the sum of all the sides of the object. Thus the perimeter of a quadrilateral is the sum of the four sides of the quadrilateral.

Given a quadrilateral with sides: n, 2n - 12, 3n + 4, n + 7

The sum is n + 2n - 12 + 3n + 4 + n + 7 = 7n - 1 = 90

Thus, 7n = 90 + 1 = 91 and n = 91 / 7 = 13.

Therefore, the length of the side KL is n = 13 centimeters.
