3 0

Answer:

a= -6

Step-by-step explanation:

Given

a=2+3a+10

In order to find the value of a, we have to isolate a on a single side of the equation

So,

subtracting 3a from both sides

a-3a = 2+10+3a-3a

=>a-3a=12

=> -2a = 12

Dividing both sides by -2

=> -2a/-2 = 12/-2

=> a = -6

The value of a in the given equation is -6 ..

Find the product of 2x^4(4x^2 + 3x + 1).
lianna [129]
We want to find the product:

                         \displaystyle{ 2x^4\cdot(4x^2 + 3x + 1).

By the \text{Distributive property}, we distribute 2x^4 over each of the three terms inside the parenthesis:

\displaystyle{ 2x^4\cdot(4x^2 + 3x + 1)=2x^4\cdot4x^2+2x^4\cdot3x+2x^4\cdot1.

Multiplying the coefficients, and adding the exponents we get:

8x^6+6x^5+2x^4.


Answer: 8x^6+6x^5+2x^4.

Write the equation of a line that passes through (-1,3) (0,8)
gizmo_the_mogwai [7]

You'll be using point slope form to solve this.

As the name suggests, you'll need the slope as well as a point. To find the slope use the slope formula: \frac{y_2-y_1}{x_2-x_1}

Plug in the points.

\frac{8-3}{0-(-1)} =\frac{5}{1} =5

The slope of this line is 5.

Point slope form is y-y1 = m(x-x1), so plug in the slope and a point into this equation. I'll use (0,8).

y-(8) = 5(x-(0))

1. Write this out without parentheses.

y-8 = 5(x)

2. Multiply 5 and x.

y-8 = 5x

3. Add 8 to both sides.

y = 5x+8

Answer is:

y = 5x+8

Step-by-step explanation:

Put the variable values in place of the corresponding variables, and do the arithmetic.

  x² +3(x +y) =

  5² +3(5 +3) = 25 +3(8) = 25 +24 = 49
