400% of a is the 1% of 400a
We want to use substitution to solve
-5x + 4y = 22 (1)
x - 3y = 0 (2)
From (2), obtain
x = 3y (3)
Substitute (3) into (1).
-5(3y) + 4y = 22
-15y + 4y = 22
-11y = 22
y = -2
From (3), obtain
x = 3y = 3*(-2) = -6
Answer: e. (-6, -2)
Sin(60) = ¹/₂√3
cos(60) = ¹/₂
tan(60) = √3
The answer is D.
Answer:
Step-by-step explanation:
Let the invested amount is x.
<u>Then the interest amount is:</u>
- x*5*2.25/100 = 675
- 0.1125x = 675
- x = 675 / 0.1125
- x = 6000
Correct choice is A
I’m pretty sure the slope is -1/2
