What is the initial value of y=-2x-5

1 answer:

6 0

This problem can be solved easily. The equation states that y is a function of x. Since this is the case, then we can get the initial value of the function when x = 0. Therefore by substitution:

y = - 2 x -5

y = - 2 (0) – 5

y = -5 (ANSWER)

What are the solutions to the quadratic equation x^2-16=0

maks197457 [2]

Good evening.

This is a incomplete quadratic equation, because it does not have the term bx. Therefore, we can solve this faster with the following strategy:

$\mathsf{x^2 - 16 = 0}$

Add 16 to both sides:

$\mathsf{x^2 - 16 + 16 = 0 + 16}\\ \\ \mathsf{x^2 = 16}$

Take the square root:

$\mathsf{\sqrt {x^2} = \pm\sqrt{16}}\\ \\ \mathsf{\boxed{\mathsf{x = \pm4} }}$

Therefore:

$\boxed{\boxed{\mathsf{S=\{-4, \ +4\}}}}$

Which description compares the domains of Function A and Function B correctly? Function A: f(x)=?3x+2

finlep [7]

Answer:

The domain of function A is all real numbers. There is no function B listed.

Step-by-step explanation:

The domain is the set of all x values. This is the set of all numbers which are inputs to the function. Since function A is a linear function y = 3x + 2, it has all real numbers as its domain. It has no restrictions.

There is no function B listed to compare.

a circle with a radius of 5 cm sits inside a 11 cm x 11 cm rectangle, what is the area of the shaded region

mojhsa [17]

Answer:

42.43 $cm^{2}$

Step-by-step explanation:

Given:

A circle with a radius of 5 cm sits inside a 11 cm x 11 cm rectangle.

Question asked:

What is the area of the shaded region as shown in the figure ?

Solution:

First of all calculate area of circle and then area of rectangle:-

$Area\ of\ cirle=\pi r^{2}$

$= =\frac{22}{7} \times5\times5\\ \\ =\frac{550}{7}\\ \\=78.571$

As here length an width both are 11 cm, we can say that this is a square.

$Area\ of\ square=(Side)^{2}$

= $=11\times11=121\ cm^{2}$

Now, area of shaded region = Area of square - Area of circle

= 121 - 78.571 = 42.429 $cm^{2}$

Therefore, the area of the shaded region will be 42.43 $cm^{2}$

In an isosceles triangle, the measure of a base angle is (2x+5)° . At the vertex the measure of an exterior angle is (5x-3)°

stich3 [128]

Answer:51.14

Step-by-step explanation:since its an isosceles triangle all interior angles are gonna be equal the exterior angle plus interior angle is will be kept equal to 360

2x+5+5x-3=360

7x+2=360

7x=358

x=51.14
