Answer:
C
Step-by-step explanation:
you're correct
Answer:
3r + t
Step-by-step explanation:
it is that because you multiply one to t and r, and the are left with 2r + r + t. You add 2r to r and get 3r, with a left over of t.
For this case we have the following equation:
Density = mass / volume
If the volume is the same, then the object with the greatest weight will be the one with the highest density.
You must know the type of way to know the value of the density.
Answer:
The weight of the blocks will depend on the density if the volume is the same.
Two lines perpendicular to each other having slopes m1 and m2 are related as:
m1 * m2=-1 ...................... (1)
First we find slope m1 of the line y=7/5x-3/5
comparing this equation with slope intercept form y=mx+b,
slope m1=7/5
NOw using rule (1) here to get value of m2
7/5 * m2 =-1
m2 =-5/7...................(2)
Now the line passes through (-4,3) and has slope m2 =-5/7
we use slope intercept form to get the value of y intercept
y=mx+b
3=(-5/7)(-4) +b
3=2.86 +b
b=0.14
At last we plug the value of b and m in slope intercept form to get the final equation as :
y=(-5/7) x + 0.14
