Answer:

y = 45 x

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

  • <em>Elk speed =45 miles per hour.  </em>
  • <em>Distance = y </em>
  • <em>Time (hours) =x </em>

So, if for every hour the elk runs 45 miles (45 x), The equation that shows the relationship between the variables is:

y = 45 x

if we replace the variable x for 1 (hour):

y = 45(1)

y (distance ) = 45 miles

Feel free to ask for more if needed or if you did not understand something.

What is the final amount if 1584 is decreased by 18% followed by a 19% increase?
Oksi-84 [34.3K]

Answer:

1,545.67

Step-by-step explanation:

step 1

if 1,584 is decreased by 18%

we know that

100\%-18\%=82\%=82/100=0.82

Multiply the number by 0.82

1,584(0.82)=1,298.88

step 2

The number 1,298.88 is increased by a 19%

we know that

100\%+19\%=119\%=119/100=1.19

Multiply the number by 1.19

1,298.88(1.19)=1,545.67

Jason designs a rectangular sandbox. He models the perimeter of the sandbox using the expression 8l+2, where l is the length of
inn [45]

Answer:

A   .The expression 2l+2(3l+1) shows the width is 1 more than 3 times the length.

Step-by-step explanation:

p = 8l + 2

Length = l

Width:

2w = p - 2l

2w = (8l + 2) - 2l

2w = 6l + 2

w = 3l + 1

Therefor w is 3 times the length plus 1

Solve. x 2 −5x−8=0 x2−5x−8=0 Enter your answers, as exact values, in the boxes. x = or x =
Sidana [21]

Answer:

x2-5x-8=0  

Step-by-step explanation:

Two solutions were found :

x =(5-√57)/2=-1.275

x =(5+√57)/2= 6.275

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "x2"   was replaced by   "x^2".  

Step by step solution :

Step  1  :

Trying to factor by splitting the middle term

1.1     Factoring  x2-5x-8  

The first term is,  x2  its coefficient is  1 .

The middle term is,  -5x  its coefficient is  -5 .

The last term, "the constant", is  -8  

Step-1 : Multiply the coefficient of the first term by the constant   1 • -8 = -8  

Step-2 : Find two factors of  -8  whose sum equals the coefficient of the middle term, which is   -5 .

    -8 + 1 = -7  

    -4+  2 = -2  

    -2+  4 = 2  

    -1 +   8 = 7
