60 + $50.45 x equals $57 .95 cents x

Mathematics
1 answer:
Zina [86]3 years ago
3 0

Answer:

x = 8

Step-by-step explanation:

The first step would be to move all terms with x to one side of the equation:

60 + 50.45x = 57.95x --> 60 + 50.45x - 50.45x = 57.95x - 50.45x -->

60 = 7.50x

The last step to obtain x is to divide both sides by the coefficient of (number next to) x:

60/7.50 = 7.50x/7.50 --> 8 = x

Ariel was told the x intercept and the y intercept of a line with a positive slope. Yet, it was impossible for Ariel to find the
alexdok [17]

A line has the following standard equation form:

y = m x + b

where m is the slope and b is the y intercept

 

So if Ariel cannot find the slope, then this would only mean that m = 0, there is no slope. And hence the line is either a straight vertical line or straight horizontal line.

 

Answer:

<span>There is no slope</span>

Find the polynomial of lowest degree with only real coefficients and having the given zeros. -7i and square root of 2
mario62 [17]

Answer:

x³ - (√2)x² + 49x - 49√2

Step-by-step explanation:

If one root is -7i, another root must be 7i.  You can't just have one root with i.  The other roos is √2, so there are 3 roots.  

x = -7i       is one root,

   (x + 7i) = 0    is the factor

x = 7i       is one root

  (x - 7i) = 0     is the factor

x = √2      is one root

    (x - √2) = 0   is the factor

So the factors are...

(x + 7i)(x - 7i)(x - √2) = 0

Multiply these out to find the polynomial...

(x + 7i)(x - 7i) =  x² + 7i - 7i - 49i²

Which simplifies to

  x² - 49i²        since i² = -1 , we have

    x² - 49(-1)  

 

      x² + 49

Now we have...

(x² + 49)(x - √2) = 0

Now foil this out...

 x²(x) - x²(-√2) + 49(x) + 49(-√2) = 0

     x³ + (√2)x² + 49x - 49√2

The cost of the hiking trip this year is 2/3 of the cost of last year's trip. This year's trip cost $32. Write an equation that
allsm [11]

Answer: (32/2)*3=48

Step-by-step explanation:

In order to find the answer, we must find one third of last year's trip. To do this, we can simply divide the cost of this years trip by two, 32/2=16.

Now if we multiply this this number by 3, 16*3=48, we can see that the total cost of last year's trip was $48.

If we'd like to turn this into one equation, it looks like this: (32/2)*3=48
