Answer:
A.
Step-by-step explanation:
Assuming the 3/8 markers are counting the lines on the number line, not the chunks in between the lines, there are 7 markers that are in the shaded area and another half distance between two markers at the end.
Answer:
She will have earned 6,008.74 JUST in interest after 72 months
Step-by-step explanation
72 months/12 months = 6 years
33% interest
Principal: $1,325
No additional $$
Plug it into compound interest formula and the total is $7,333.74
I subtracted the initial investment to see how much interest was earned.
Answer:
(9, 6)
Step-by-step explanation:
add equations together: (x + y = 15) + (x - y = 3) --> x + x + y - y = 15 + 3 --> 2x = 18
isolate the variable: 2x/2 = 18/2 --> x = 9, so the x-coordinate is 9
substitute 9 in x's place in one of the equations: 9 + y = 15
solve for y: y = 15 - 9 --> y = 6, so the y-coordinate is 6
combine x and y coordinates together: (9, 6)
The product of the slopes of the perpendicular lines must equal -1. Let the unknown slope be m.
(5/4)m = -1
m = -(4/5)
The required equation is of the form:
y = -(4/5)x + b
Plugging in the coordinates of the given point, we get:
5 = -(16/5) + b
b = 8 1/5.
The required equation is therefore:
y = -(4/5)x + 8 1/5
