Hi! This is a difficult problem because I'm not too familiar with exponential functions but I think that 4^x is an exponential function and 2 multiplied by it means that it's multiplying by an exponential function. Does it make the whole rule exponential? I'm not sure but I don't think it does.

I need to know how to do Solving Systems of Equations by Elimination

vredina [299]

The point of elimination is to have one variable so example

3x + 2y = 4

7X + 3y = 5

1) Try to find a way to have one variable

7(3x + 2y = 4) ----> 21x + 14y = 28

-3(7x+ 3y = 5) -----> -21x -9y = -15

2) add

0 + 5y = 13

3) solve for the last variable

5y = 13
y = 13/5 = 2 3/5 = 2.8

4) Subsitute the variable to get the other one

3x + 2(2.8) = 4

3x + 5.6 = 4

3x = -1.6

x = 0.533333333 (continue)

The intersection would be 0.53 with a line above the 3 and 2.8. (0.5333 , 2.8)

Hope you understand!!

Given the graph of a degree 3 polynomial below, complete the table of values for either the x-value of a zero, or the multiplici

leva [86]

The roots or zeros of a polynomial are the points it crosses the x-axis.

The roots of the polynomial in order from least to greatest are -5, 0 and 5

From the graph (see attachment), we have the following highlights

<em>The graph cross the x-axis at x = -5</em>
<em>The graph cross the x-axis at x = 0</em>
<em>The graph cross the x-axis at x = 5</em>

The points at which the graph crosses the x-axis are the roots of the graph.

So, the roots are: -5, 5 and 5

A model car has a scale factor of 1 64 164 The diameter of a tire on the model is 0.41 inches. So, the diameter of the tire on a

Alchen [17]

Answer: 26.24 inches

Step-to-step explanation:

Given:

The scale factor to model car= $\frac{1}{64}\ inches$

Thus, if diameter of tire of the actual car is k then diameter of model car = $\frac{1}{64}k$

Since, the diameter of tire of the model car= 0.41 inches

$\\\Rightarrow\frac{1}{64}k=0.41\\\Rightarrow\ k=0.41\times64\\\Rightarrow\ k=26.24\ inches$

hence, the diameter of tire of the actual car= 26.24 inches
