Point-slope form: y - 5 = (-1/5)(x - 7)
standard form: x + 5y = 7
slope-intercept form: y = (-1/5)x + (7/5)
***note: (-1/5) = -0.2 and (7/5) = 1.4
Answer:
x = 7
Step-by-step explanation:
See the attached figure.
As shown: A C D F is a trapezoid and BE is a mid-segment.
The mid-segment of the trapezoid is the average of its bases.
BE = 0.5 ( A F + C D)
Given: CD = 18 , BE = 2x + 10 and A F = 6x - 12
So,
2x + 10 = 0.5 ( 18 + 6x - 12)
Solve for x
2x + 10 = 0.5 (6 + 6x)
2x + 10 = 3 + 3x
10 - 3 = 3x - 2x
∴ x = 7
<u>So, the value of x is 7</u>
The answer to 29×97 would be 2813
Answer:
.278
Step-by-step explanation:
There are 9 coins
P (nickel) = number of nickels/ total
= 5/9
Keeping the coin
We now have 8 coins, 4 nickels and 4 dimes
P (nickel) = number of nickels/ total
= 4/8 = 1/2
P(nickel, keep, nickel) = 5/9* 1/2 = 5/18=.2777777777
When you add 8.5+3.95+11.15, you get 23.6, that is your total money spent on lunch for that week. The correct answer is B.
