What is the soluton to the linear equation? 4b+6=2-b+4

Mathematics
1 answer:
Ipatiy [6.2K]3 years ago
4 0
4b + 6 = 2 - b + 4 // Given
4b + 6 = -b + 6 // Simplifying (adding 2 and 4)
5b + 6 = 6 // Addition Property of equality (added b to both sides)
5b = 0 // Subtraction Property of equality (took 6 from both sides)
b = 0 // Division Property of equality
(Divided 0 by 5)

HELP PLS ASAP<br><br><br><br> -5 = 5/12a pls evaluate
Setler79 [48]

Answer:

a = -12

Remember that when a variable is times with a number, you <u>divide</u> the number on both sides.

When a variable is divided by a number, you <u>multiply</u> the number on both sides.

Hope this helps you. Thank you !!

Answer:

  (a) d = 0.012v^2

  (b) 4.8 m

  (c) 25 m/s

Step-by-step explanation:

(a) Writing an equation to fit a bunch of data is often a matter of trial and error. You can often get an idea of the sort of function that is involved by graphing the data points.*

When we do that, we see the relationship is non-linear with an upward curvature. It might be described by a polynomial or exponential function.

When we try a quadratic equation, we find the fit is really quite good. The graphing calculator that does this quadratic regression analysis tells us the equation is essentially ...

  d = 0.012·v^2

__

(b) The equation predicts a depth of 4.8 m.

  d = 0.012·20^2 = 4.8

__

(c) Solving for speed, we get a speed of 25 m/s.

  7.5 = 0.012v^2

  625 = v^2 . . . . . . divide by .012

  25 = v . . . . . . . . . take the square root

_____

* The energy of a falling object is proportional to the square of its speed. If we assume that the depth of penetration into the clay is proportional to the energy absorbed, then it is not surprising to see a quadratic relationship between speed and distance. What is surprising is that this relationship would show up in middle school math problem, not a high-school physics problem.

Essentially, you have to assume the form of the equation, then find the coefficients that make it so. Working with the evenly spaced table values of 5, 10, 15 m/s can simplify the effort.

A graphing calculator or spreadsheet can do the bulk of the work once the data is entered.

Rewrite the quadratic function in the form that best reveals the zeros of the function: f(x)=2(2x^2+4x)+3
olga2289 [7]

Answer:

Step-by-step explanation:

The given quadratic function is f(x)=2(2x^2+4x)+3

Multiplying through to open the brackets,

f(x)=4x^2 + 8x +3

To find the zeros, we will equate

f(x) = 0

Therefore,

4x^2 + 8x +3 = 0

Finding two numbers such that when we multiply them, it gives us 12xx^2 and when we add them, it gives us 8x, we have 6x and 2x. Therefore,

4x^2 + 8x +3 = 0 is expressed as

4x^2 + 2x + 6x +3 = 0

2x(2x + 2) +3(2x + 3) = 0

(2x +2)(2x +3) =0

f(x) = 2x +2)(2x +3)
