Answer:

y=0

Step-by-step explanation:

Definition:An expression is undefined at the value(s) at which the denominator equals zero.

We are to determine the value of y that makes the expression undefined.

$\dfrac{6y^3+2y^2}{10y^2}$

We equate the denominator to zero and solve for y.

$10y^2=0\\y^2=0\\y=0$

Therefore, at y=0, the given expression is undefined.

A line passed through the origin and has a slope of 1/2.

baherus [9]

Answer:

D. (2, 1)

Step-by-step explanation:

slope = 1/2

y-intercept = 0

Equation: y = 1/2 x

Choice A:

x = 0

y = (1/2)(0) = 0

Choice A does not work.

Choice B:

x = 1/2

y = (1/2)(1/2) = 1/4

Choice B does not work.

Choice C:

x = 1

y = (1/2)(1) = 1/2

Choice C does not work.

Choice D:

x = 2

y = (1/2)(1) = 1

Choice D works.

Help plsss!!!! Thnk you!!!!

lina2011 [118]

Step-by-step explanation:

General quadratic equation: y = ax² + bx + c.

When x = 0, y = -3.

=> (-3) = a(0)² + b(0) + c, c = -3.

We now have y = ax² + bx - 3.

When x = 2, y = -4.

=> (-4) = a(2)² + b(2) - 3, 4a + 2b - 3 = -4,

4a + 2b = -1.

Our 1st system of equations is 4a + 2b = -1.

When x = 4, y = -3.

=> (-3) = a(4)² + b(4) - 3, 16a + 4b - 3 = -3,

16a + 4b = 0, 4a + b = 0.

Our 2nd system of equations is 4a + b = 0.

Now we solve the system of equations:

4a + 2b = -1

- (4a + b = 0)

=> b = -1

Hence 4a + (-1) = 0, 4a = 1, a = 1/4. (B)

What is the area in square units of the shaded region

sergey [27]

Answer:

The answer to your question is the letter D. 19.5 u²

Step-by-step explanation:

Process

1.- Calculate the Area of the rectangle ABCD

Area of a rectangle = base x height

= (4 + 5) x 3

= 9 x 3

= 27 u²

2.- Calculate the area of the large triangle

Area of a triangle = base x height/2

-Substitution

Area of a triangle = (4 + 5) x 3/2

-Simplification

Area of a triangle = 9 x 3/2

-Result

Area of a triangle = 13.5 u²

3.- Calculate the area of the small triangle

Area of the triangle = 4 x 3/2

Area of the triangle = 6 u²

4.- Sum up the area of the triangles

Shaded area = 13.5 + 6 = 19.5 u²
