Step-by-step explanation:
Given mCDF = (3x + 14), mFDE = (5x - 2), and mCDE = (10x – 18)", then the expression mCDE = mCDF+mFDE is true.
To get x, we will substitute the given angles into the formula as shown;
(10x – 18) = (3x + 14)+ (5x - 2)
10x-18 = 3x+5x+14-2
10x-18 = 8x+12
10x-8x = 12+18
2x = 30
x = 30/2
x = 15
Find the measure of each angle
For mCDF:
mCDF = 3x + 14
mCDF = 3(15)+ 14
mCDF = 45+14
mCDF = 59°
For mFDE:
mFDE = (5x - 2)
mFDE = 5(15) - 2
mFDE = 75-2
mFDE = 73°
For mCDE:
mCDE = (10x – 18)
mCDE = 10(15) - 18
mCDE = 150-18
mCDE = 132°
The y-intercept is 10 hours and it represents the number of hours it took to empty one tank
Answer:
1
Step-by-step explanation:
5/7+2/7 add the numerator to equal 7/7 simplify to 1/1 equals 1
<span>M1=[<span>(4a+0)/2 <span>,(4b+0)/2] = (2a, 2b)
</span></span></span>M2=[(4c+4d)/2 ,(4b+0)/2] = [2(c+d) , 2b]
answer
coordinate points (x,y) :
(2a, 2b) , [2(c+d) , 2b]
Answer:
19/24
Step-by-step explanation:
slope = rise/run = (y1 - y2) / (x1 - x2)
s = (19 - 0) / (8 - -16)
s = 19/24
