If y=2x^2-5x-3 find the value of y if x= -1

Gelneren [198K]

Answer:

y = 4

First we want to raise -1 to the power of 2

y = 2 * 1 - 5 * -1 - 3

Multiply

2 - 5 * -1 - 3

Multiply

y = 2 + 5 - 3

y = 7 - 3

y = 4

3x -2y = -6 and y = x+5

sweet [91]

Answer:

x = 4, y = 9.

Step-by-step explanation:

3x -2y = -6 and y = x+5

Substitute y = x + 5 in the first equation:

3x - 2(x + 5) = -6

3x - 2x - 10 = -6

x = -6 + 10

x = 4

So y = 4 + 5 = 9.

<h3>What is a circle?</h3>

It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

Claire has a hot tub with a diameter of 7 feet. She wants to purchase a cover to protect the hot tub.

The area of the circle is given by

$\rm Area = \dfrac{\pi}{4}d^2$

We have d = 7 ft, then the area of the circle will be

$\rm Area = \dfrac{3.14}{4}*7^2\\\\Area = 38.5 \ ft^2$

More about the circle link is given below.
