Answer:
y=1
Step-by-step explanation:
you can use those points to find the slope
use the equation 
then plug in the numbers
so (1-1)/(-8-7) = 0/15 so the slope is zero meaning it is a horizontal line which we can tell logically because the y coordinates of both points are 1.
so if you plug those numbers into the formula y=mx+b where m is slope and b is the y intercept then
you get y=0*x+1
then 0*x is just zero and it goes away so the equation for this line is y=1
Hope this helps! :)
B. because you do 16*2*h + 8*2*h and you get 128 + 64 = 192
Answer:
We need the groups
Step-by-step explanation:
x=0 .
−2(8+8x)+7x=−7x+2(x−8)
Step 1: Simplify both sides of the equation.
−2(8+8x)+7x=−7x+2(x−8)
(−2)(8)+(−2)(8x)+7x=−7x+(2)(x)+(2)(−8)(Distribute)
−16+−16x+7x=−7x+2x+−16
(−16x+7x)+(−16)=(−7x+2x)+(−16)(Combine Like Terms)
−9x+−16=−5x+−16
−9x−16=−5x−16
Step 2: Add 5x to both sides.
−9x−16+5x=−5x−16+5x
−4x−16=−16
Step 3: Add 16 to both sides.
−4x−16+16=−16+16
−4x=0
Step 4: Divide both sides by -4.
−4x
/−4
=
0
/−4
x=0
Step-by-step explanation:
the distributing ratio is 2:5.
that means for every 2 white marbles there must be 5 blue marbles.
so, we are taking about "groups" or multiples of 7 (2+5 = 7).
now, even 7×7 = 49 is too small.
but the next multiple of 7 (7×8 = 56) is now big enough to include at least 50 marbles.
so, in order to keep the 2:5 ratio strictly in place, the minimum number of marbles in the bag is 56.
