whether the answer choices
Yes! The smaller trapezoid is being turned into the bigger one. Take 10.5 and divide that by 7. This would be 1.5. You can double check your work with 15 divided by 10.
Answer = 1.5
No, it's not.
15/28 equals to (about) 0.54 while 25/45 is (about) 0.56.
They are close, but not equivalent.<span />
Well in order to find the slope the equation should be in y= mx +b format, where m=slope
to do this you take your equation,
7x=-3y+15
and notice how the x and y are in the wrong position ,
add the 3y to both sides and subtract 7x from both sides
7x=-3y+15
+3y +3y
7x+3y=15
-7x. -7x
3y=-7x+15
now we need the y to be by itself so we divide the entire equation by 3 and get
y=-7/3x+5
so -7/3 or 2.33 or 2 1/3 would be the slope, the slope of parallel lines are equal
When we distribute, we multiply the number outside of the parenthesis to every number inside the parenthesis.
So we have:
