A, B are correct
Step-by-step explanation:
Where is the equals sign in the second one? Are we supposed to solve for x?
Answer:
the slope is -8/5
Step-by-step explanation:
we need to get the equation in the form
y= mx+b where m is the slope and b is the y intercept
8x + 5y =40
subtract 8x from each side
8x-8x + 5y = -8x +40
5y = -8x+40
divide each side by 5
5y/5 = -8x /5 + 40/5
y = -8/5 x +8
the slope is -8/5 and the y intercept is 8
Answer:
Step-by-step explanation:
Step 1: We make the assumption that 160 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that 100%=160
Step 4: In the same vein, = x%=140.
Step 5: This gives us a pair of simple equations:
100%=160(1).
x%=140(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100% / x% = 160 / 140
Step 7: Taking the inverse (or reciprocal) of both sides yields
x% / 100% = 140 / 160
x% = 87.5%
therefore, 140 is 87.5% of 160
