If you would like to know what expression would show the length of the poster, you can calculate this using the following step:
Amanda's poster ... 0.85 meter long
Orlando's poster ... 0.55 meter less than 1 meter long: 1 meter - 0.55 meter = 0.45 meter
Place a point on (4,1) then count one space up and two spaces to the right and plot the second point there. So (4,1) and (6,2). That should graph the line automatically when you place two points
Answer:
Step-by-step explanation:
If x represents the amount invested at 7%, then the amount invested at 13% is x+300. Lydia's total interest is ...
0.07x +0.13(x +300) = 252
0.20x = 213 . . . . . subtract 39
x = 213/0.20 = 1065
Lydia has $1065 invested at 7% and $1365 invested at 13%.
Answer:
y = - x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 1 ← is in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
= - = - , thus
y = - x + c ← is the partial equation
To find c substitute (8, - 2) into the partial equation
- 2 = - 4 + c ⇒ c = - 2 + 4 = 2
y = - x + 2 ← equation of perpendicular line
