Answer:
Perpendicular: 4, Parallel: -1/4
Step-by-step explanation:
The slope of a line perpendicular to the given line is the opposite inverse of the slope to the line.
First write the equation of the line in slope-intercept form
-x-4y=7
-4y=x+7
y=-(1/4)x-7/4;
The slope to the line is -1/4; Now find the slope of the perpendicular line;
-(-1/4)^-1 = 4
4
The slope of a line parallel to a line is the same as the given slope;
when we calculated the given slope, it was -1/4
The slope of the line parallel to this line is also -1/4
-1/4
Answer:
24 ft^2
Step-by-step explanation:
<u>Triangle:</u>
A = 1/2bh
A = 1/2*8*8
A = 1/2*64
A = 32 ft^2
<u>Rectangle</u>:
A = lw
A = 4*2
A = 8 ft^2
<u>Triangle - Rectangle:</u>
A = 32 - 8
A = 24 ft^2
Answer:
19x - 32
Step-by-step explanation:
8[x-7]+11[x+8} distribute the 8 and 11
8x - 56 + 11x + 88 combine like terms
19x - 32
Answer:
w2+7w>293
Step-by-step explanation:
I think x=42 because 48/x=8/7 you cross multiply meaning you do 48*7=336, then 8*x. So it would be 8x=336.
8x/8=336/8 so x=42.
