Answer:
y= -2x-7
Step-by-step explanation:
Start with the linear equation formula.
y= mx+b
identify what you already have.
x= -2 and y= -3 m(slope)= -2
we are trying to find b, so plug in what you have.
-3=-2(-2)+b
simplify.
-3= 4+b
subtract 4 on both sides.
-7= b
set up your equation without the x and y value.
y= -2x-7
Answer:
11 79/80
Step-by-step explanation:
2+4+3+ 3/4+4/5+8/9
=9+ 3(5*9) +4(4*9) + 8(5*4)/4*5*9
=9 + 135+ 144+160/180
=9+ 439/180
=9+2 + 79/80
=11 79/80
Answer:
8.625 ft for each side.
Step-by-step explanation:
This one's pretty simple. It's a square, so all of its sides are the same length. It's perimeter is given as 34.5 ft, so all you have to do is divide 34.5 by 4 since squares have 4 sides. 34.5/4 is 8.625, which, rounding to the nearest 1/100th, is 8.63. Rounding to the nearest 1/10th it's 8.6, and rounding to the nearest 1th is 9 (although i doubt saying 1th is right, but just because).
