The input is known as x and the output is known as y in math.
So you’re stating that we’re making the equation equal the output, y, and we’re adding based off of the word “more”. Now that we know we’re adding, we have to find what we are adding together. We are adding x and 11 is that it equals y. Note that x and y could be many different variables and values.
Y= x+11

find the area of the isocele triangle formed by the points of intersection of parabolas y=-x^2+9 and y=2x^2-3 and the origin
leonid [27]

Answer:

10\ \text{sq. units}

Step-by-step explanation:

The parabola's are

y=-x^2+9

y=2x^2-3

So

-x^2+9=2x^2-3\\\Rightarrow 12=3x^2\\\Rightarrow \\\Rightarrow x=\sqrt{\dfrac{12}{3}}\\\Rightarrow x=\pm 2

y=-x^2+9=-(2)^2+9\\\Rightarrow y=5

y=-(-2)^2+9=5

So, the points at which the parabola's intersect each other is (2,5) and (-2,5)

The three points of the triangle are (2,5), (-2,5) and (0,0)

Area of a triangle is given by

A=\dfrac{1}{2}[x_1(y_2-y_3) + x_2(y_3-y_1) + x_3(y_1-y_2)]\\\Rightarrow A=\dfrac{1}{2}[2(5-0)+(-2)(0-5)+0(5-5)]\\\Rightarrow A=10\ \text{sq. units}

Area of the triangle formed is 10\ \text{sq. units}.

You need to add two mixed numerals.
One is positive and one is negative.
To add a positive number and a negative number, first take the absolute value of both, making them both positive. Then subtract the smaller absolute value from the larger absolute value. Finally, the sign of the answer is the same sign as the number that has the larger absolute value.

The numbers are -4 5/8 and 2 1/8

Take absolute values:
|-4 5/8| = 4 5/8
|2 1/8| = 2 1/8

Subtract the smaller absolute value from the larger absolute value.

4 5/8 - 2 1/8 = 2 4/8 = 2 1/2

The greater absolute value is 4 5/8.
Since the number with the larger absolute value was -4 5/8, a negative number, the answer is negative, -2 1/2

-4 5/8 + 2 1/8 = - 2 1/2

5x5 + 8x2 + 2x – 3x9 – 8x4 – 4x5
Vladimir79 [104]
I'm assuming that the number after the variable is supposed to be the exponent.

5x^{5}+8 x^{2} +2x-3x^{9}-8x^{4}-4x^{5}

Combine like terms to get:

-3x^{9}+x^{5}-8x^{4}+8x^{2}+2x
