Answer:

x = -20

y = -62

Step-by-step explanation:

Suppose x and y two number and such that :

  • their sum = -102
  • and y is 62 less than x

Which means :

  • x + y = -102
  • x - y = 62

then

  • x + y = -102
  • x = y + 62

then

x + y = (y+62) + y = -102

then

2y + 62 = -102

then

2y = -164

then

y = -164/2 = -82

therefore

x = y + 62 = -82 + 62 = -20

For the graph of the function, identify the axis of symmetry, vertex and the formula for the function.
Akimi4 [234]

Answer:

The answer to your question is the third choice.

Step-by-step explanation:

The axis of symmetry is the dotted red line which is located in x = 1/2

The Vertex is the lowest point of the parabola which is (1/2, -1)

The equation of the function is:

                        (x - h)² = 4p(y - k)

-Substitution

                        (x - 1/2)² = 4p(y + 1)

-We can not know the value of p

                        x² - x + 1/4 = y + 1

Discarding choices, there are two possible answer, the second and the third choices, but because of the Vertex (0.5, -1), i think the right answer is the third choice.

The area of a rectangle is 70 in 2 and the length of the rectangle is 3 in. Longer than the width
Snezhnost [94]

Alright, lets get started.

I hope, the dimensions of rectange are asked in this question.

Suppose the width of rectangle = x in

Given that length of the rectangle is 3 in longer than the width.

It means length of the rectangle = (x+3) in

Now, the area of the rectangle = lenght * width

area of the rectangle = x * (x+3)

area of the rectangle =x^2+3x

The area of a rectangle is 70 in square (given in question)

Equalling both areas

x^2 + 3x = 70

Subtracting 70 in both sides

x^2 + 3x - 70 = 70 - 70

x^2 + 3x - 70 = 0

Factoring

(x-7)(x+10) = 0

It will give two values of x

x = -10 (which is not possible because length could not be negative)

x = 7

Means width = 7 in

length = 7 + 3 = 10 in

Means the dimensions of rectangle are 7 in and 10 in. : Answer

Hope it will help :)

What is the area of a square with side lengths of 3/5 units?
rodikova [14]

<em>To find the area of a square, multiply the side length by itself, also known as sqaring the side length.We must solve 3/5 x 3/5.3/5 x 3/5 = 0.36The units we'll use is because units are the unt we're given, and it is squared because it is the area of a shape.</em>
