Answer:
-5/25
Step-by-step explanation:
-3/7=-16/24
-3/4=-21/24
for 2a, use the theorems of geometry and such to look at the area of the square as 16 squares total, then use the lengths and Sim/cos rule for the triangular area, then subtract and you have you shaded area.
Answer:
answer is 26.6%
Step-by-step explanation:
i first converted the fraction "40/150" to a decimal by dividing 40 by 150
40 divided by 150 is .26 (rounded)
and then i did .26 times 100
which gave me 26.6
:P hope this helped even doe im kinda late-
Answer:
y = 7/2x - 20.
Step-by-step explanation:
The slope of the given line is -2/7, therefore the slope of the line perpendicular to it is - 1/ -2/7 = 7/2.
When x = -4, y = -6 so we substitute x1 = 4, y1 = -6 and m ( the slope) = 7/2 in the point slope form of a line:
y - y1 = m(x - x1)
y - (-6) = 7/2(x - 4)
y + 6 = 7/2x - 14
y = 7/2x - 20.
Its simple, so these are two "y=mx+b" form lines that are limited by the signs on the right. Your first line f(x)=-x-4 has to be between -3 and 1 on the x-axis.
You would plot a point at (0,-4) like normal, then go down one, right one as the slope is -1. you would make the dot at 1 though unfilled as x does not equal to 1. It is less than 1. º Should look like the dot I just inserted.
The second line would be plotted, at (0,-6). You would then make a horizontal line between 1 and 5. º-------• (Should look like this)
IMPORTANT:
FILLED DOT - EQUAL TO
UNFILLED DOT - Not equal to
