Answer:
Step-by-step explanation:
Raising a number to the 1/2 power is the same as square rooting it. Raising something to the 1/2 power is the same as asking for 2 equal factors that can be multiplied together to give you that number. For example, is 3, but 9^1/2 is also 3.
We are given that Kristine spends $20 and saves the rest each time she get paid.
We can use slope-intercept form y=mx+b to represent the equation.
Where x represents the amount Kristine earns and y represents the amount she saves.
Kristine spends $20. Therefore b= -20.
Plugging mx as just x and b=-20.
<h3>y = x-20.</h3><h3>If we plug y=0, we get </h3><h3>0 = x-20</h3><h3>x=20.</h3><h3>We can see in 4th option we have x-intercept =20.</h3><h3>Therefore, correct option is 4th option. </h3><h3 />
Answer:
The correct ordered pair is (7,1)
Step-by-step explanation:
The given system has equations:
We make x the subject in the first equation to get:
Put equation 3 into equation 2 to get:
Expand:
Put y=1 into equation 3 and solve for x.
The correct ordered pair is (7,1)
