A rental car company charges a fixed fee of $30 plus $0.05 per mile. Let C represent the total cost of renting a car and driving
Blababa [14]
We know that renting the car will cost $30, regardless of whether you drive it any where or not
So far
C = $30
On the end of this equation, we want to be able to add another value, that can vary depending on the quantity of M (number of miles)
The second value is $0.05 multiplied by how many miles are travelled
Also expressed as $0.05M

Finally, just fix the two parts together

C = $30 + $0.05M

Gracie can do a 4-foot long jump. How many jumps will she have to do in order to jump a total of 8 yards?
vampirchik [111]

Answer

I think it would be 8 jumps, might not be correct though.

Step-by-step explanation:

1 yard = 3 foot

There is already 3 foot inside of 4 foot so you just keep adding until you hit 8 yards.

Factorise fully -x - 8
natta225 [31]

Answer:

x = -8 please mark brainliest

Step-by-step explanation:

Pull out like factors :

  -x - 8  =   -1 • (x + 8)

Equation at the end of step  1  :

Step  2  :

Solving a Single Variable Equation :

2.1      Solve  :    -x-8 = 0

Add  8  to both sides of the equation :

                     -x = 8

Multiply both sides of the equation by (-1) :  x = -8

Please help with this asappppppppll

We are given with a circle and we need to find the <em>equation of the circle</em> , but first let's recall that , the equation of a circle with radius<em> 'r'</em> and centre at <em>(h,k) </em>is given by {\bf{(x-h)^{2}+(y-k)^{2}=r^{2}}}

Now , here as as the circle cuts the +ve x-axis at (9,0) . So , it's radius is 9 units or the 2nd way is to measure the distance from centre of the circle to the point where the circle cuts the graph , as the centre is at Origin , so here <em>(h,k) = (0,0)</em> .Which means that the centre is located at the point whose coordinates are<em> (0,0)</em> which is also known as origin . Now , finding the equation of the circle :-

{:\implies \quad \sf (x-0)^{2}+(y-0)^{2}=(9)^{2}}

{:\implies \quad \bf \therefore \quad \underline{\underline{x^{2}+y^{2}=81}}}

<em>This is the required equation of Circle</em>
