A=567 km+900 km
a=1,467 km

b=567 km+169 km
b=736 km

x^2/a^2+y^2/b^2=1
x^2/(1,467)^2+y^2/(736)^2=1

Please, see the graph in the attached graph.

Thanks.

Y=-6x + 5<br> x - y = 5
rodikova [14]

Answer:

y = \frac{-25}{7} or -3.571

x = \frac{10}{7} or 1.429

Step-by-step explanation:

x - y = 5

x = 5 + y

Solve for y:

y =  -6x + 5

y =  -6(5 + y) + 5  Substitute x with 5 + y

y = -6(5) - 6y + 5

y = -30 - 6y + 5

y + 6y = -30 + 5

7y = -25

y = \frac{-25}{7} or -3.571

Solve for x:

x = 5 + y

x = 5 + -25/7

x = \frac{10}{7} or 1.429

Write an equation that you can use to find the number of refills Keith bought. A restaurant sells a coffee refill mug for $6.75.
Evgesh-ka [11]

Answer:

<h2> 6.75+1.25x=31.75</h2>

Step-by-step explanation:  

let x be the number of refils

also given is that the cost of one refill is $1.25

hence the total refil will be 1.25x

given that the cost of a mug is $6.75

6.75+1.25x=31.75

therefore  the expression that can be used to solve for the number of refills is

6.75+1.25x=31.75
