Answer: slope, m = -7/3
Step-by-step explanation:
The equation of the line is
7x+3y=15.
To find the slope,
We will consider the standard slope intercept equation also known as the equation of a straight line,
y = mx + c
Where m = slope( change in y values divided by change in x values)
c = the y intercept. This is the point where the straight line cuts across the y axis
Looking at the given equation, 7x+3y=15,
We would need to rearrange it and make y the subject of the formula. It becomes
3y = 15 - 7x
Dividing the right hand side of the equation and left hand side of the equation by 3,
y = -7x/3 + 15. Comparing with the slope intercept equation,
m = -7/3
1) D is your answer.
Isolate the y:
2x = 3y - 5
first add 5 from both sides
2x (+5) = 3y - 5 (+5)
Next, divide 3 from both sides to isolate the y
(2x + 5)/3 = (3y)/3
y = (2x + 5)/3
2) None of the above is your answer
Plug in points for each equation. None of them work for more than 1 or 2 points. (they are not true for all points) ∴ None of the above is your answer

Answer:
Step-by-step explanation:
The length of a rectangle is three times the width. Find the width if the perimeter is 80 cm.
PERIMETER = 2L +2W
L=3W
PERIMETER= 2(3W) +2W
80= 6W +2W =8W
80=8W
W=10
L=3X10=30
CHECK]
(2x10) + (2X30) =20+60=80

You have to put the two angles in the same units, because now the first one is in radians and the second one in degress.
To pass 1.38 radians to degrees you can use the ratio 180° / π radian = 1.
So 1.38 radian * 180° / 3,1416 = 79 °.
So the angle in the Column A is 2° wider than the angle in the Column B.
