Answer:
90 is the orrect answer because I said so
Step-by-step explanation:
1/2
When you put a square root into exponential form, the square root turns into an exponential fraction. Since the square root is 2, our fraction would be 1/2
If our root was a cube root, our exponent would be 1/3, etc.
To write the equation of a line I need slope and y intercept (0,y)
I have y intercept (0,7) of +7 as written in the equation
The equation y=-5/4x + 11/4 has a slope of -5/4
To get perpendicular slope is negated reciprocal
so take -5/4 and flip it -4/5 and change the sign (in this case negative to positive) 4/5
so the new equation is y=4/5x +7 (third one)
Answer:
Step-by-step explanation:
First system: no solution, since the two lines are parallel; they never cross.
Second system: one solution
Third system: infinitely many solutions, since the second equation is a multiple of the first
