Answer:

4x^2+28x^3 : 4x^2 (7x + 1)

Step-by-step explanation:

4x^2+28x^3

Apply exponent rule: \:a^{b+c}=a^ba^c

x^3=xx^2

=28xx^2+4x^2

Rewrite 28 as 4\cdot \:7:

=4\cdot \:7xx^2+4x^2

Factor out common term 4x^2:

=4x^2\left(7x+1\right)

Hope I helped, if so may I get brainliest and a thanks?

Thank you, have a good day! =)

If (a, -5) is a solution to the equation 3a = -2B - 7, what is a?
Andrew [12]
I think what you need to do is make B = -5
3a = -2(-5) - 7
3a = 10 - 7
3a = 3
a = 1

Which statement is true about the discontinuities of the function f(x)?
Leno4ka [110]

Answer:

  (a)  There are asymptotes at x=3/2 and x=-1/3

Step-by-step explanation:

The denominator zeros can be found by factoring:

  f(x) = (x +1)/((2x -3)(3x +1))

Neither of the denominator factors is cancelled by the numerator factor, so each represents a vertical asyptote, not a function hole.

The asymptotes are at the values of x where the denominator is zero:

  2x -3 = 0   ⇒   x = 3/2

  3x +1 = 0   ⇒   x = -1/3

Please help with this math
gladu [14]

Answer:

\boxed{\textsf{ The correct option is \textbf{ option C } . }}

Step-by-step explanation:

Given that Sara bought a car for $ 23,000 . The interest of loan is 2 .5% . And we need to write a equation g(t) to represent the amount of money that she will owe after t years. Also the amount is compound annually . We know the formula of CI as ,

<u>Compound</u><u> </u><u>Interest</u><u> </u><u>:</u><u>-</u>

\qquad\boxed{\boxed{ \sf CI =Amount\bigg( 1 +\dfrac{Rate}{100}\bigg)^{(time)} }}

Let us take that ,

\sf\implies f(x)=g(t)

<u>Put </u><u>on </u><u>the </u><u>respective</u><u> values</u><u> </u><u>:</u><u>-</u>

\sf\implies f(x) = Amount\bigg( 1 +\dfrac{Rate}{100}\bigg)^{(time)} \\\\\sf\implies f(x)= 23,000 \bigg( 1 + \dfrac{2.5}{100}\bigg)^t\\\\\sf\implies f(x)= 23,000 \bigg( 1+\dfrac{25}{1000}\bigg)^t \\\\\sf\implies \boxed{\pink{\frak{ f(x)= 23,000 ( 1+0.025)^t }}}
