8+9t-3+4 please help me​

Mathematics
1 answer:

Answer:

t = -1

Step-by-step explanation:

8 + 9t - 3 + 4    

Combine like terms

(8 - 3 + 4) + 9t

9 + 9t

9t + 9

Get <em>t</em> by itself

9t + 9 = 0

     -9    -9

9t = -9

Divide both sides by 9 to find <em>t</em>

t = -1

Let f(x)=2.912345x^2+3.131579x-0.099999
Rudiy27
A.) Integers are positive and negative counting numbers. So, in order to find the integer coefficients, round off the coefficients in the equation to the nearest whole number. The function for g(x) is:

g(x) = 3x²+3x

B.) Substitute x=4 to the two functions.

f(x) = 2.912345x²<span>+3.131579x-0.099999
</span>f(4) = 2.912345(4)²+3.131579(4)-0.099999
f(4) = 59.023837

g(x) = 3x²+3x
g(4) = 3(4)²+3(4)
g(4) = 60

C.) The percentage error is equal to:

Percentage error = |g(4) - f(4)|/f(4)  * 100
Percentage error = |60 - 59.023837|/59.023837  * 100
Percentage error = 1.65%

D.) If x is a large number, for example x=10 or x=20, then g(x) would be an overestimate. This is because the value of x is raised to the power of 2. So, as the x increases, the corresponding function would increase exponentially. Even at x=4, g(x) is already an overestimate. What more for larger values of x? That means that the gap from the true answer f(x) would increase.

Answer:

y= -3/4x+2

Step-by-step explanation:

3x+4y=8

-3x       -3x

----------------

4y=-3x+8

Divided by 4 on each sides

y= -3/4x+2
