Is (–5, 0.5) a solution of this system?

x – 4y = –7,

0.2x + 2y = 0

Yes, the (–5, 0.5) is the solution set of the system.

Step-by-step explanation:

Given that:

x – 4y = –7   eq1

0.2x + 2y = 0 eq2

Now we have to check that, (–5, 0.5) is the solution of given system or not.

So from the given solution set:

x = -5

y = 0.5

Putting these values in eq1:

-5 - 4(0.5) = -7

By simplifying,

-5 - 2 = -7

-7 = -7  (satisfied)

Now putting the values of x and y in eq2:

0.2(-5) + 2(0.5)=0

By simplifying,

-1 +1 = 0

0 = 0 (satisfied)

i hope it will help you!

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2
