Is (2,-2) a solution to the following system of equations?

yes?

Step-by-step explanation:

is this a true or false question

(its true)

No

Step-by-step explanation:

Remark

No

If it was, the value for x should give you the same y in both cases. Try it out.

First Equation

y = -2x + 2

x = 2

y = -2*2 + 2 = -4 + 2 = - 2

Second equation

x = 2

y = 7*2 + 11

y = 14 + 11

y = 25

Conclusion

They are no where near being the same

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
