Answer:
x=-11/8
Step-by-step explanation:
x-(5/8)=-2
Give the -2 a common denominator to make it easy
x-(5/8)= -16/8
Add the 5/8 to the -16/8
x= -11/8
It causes the breakdown and decay to the rocks. It occurs when the weather water is slightly acidic.
Angle D is 180° -75° -45° = 60°. Drawing altitude MX to segment DN divides the triangle into ΔMDX, a 30°-60°-90° triangle, and ΔMNX, a 45°-45°-90° triangle. We know the side ratios of such triangles (shortest-to-longest) are ...
... 30-60-90: 1 : √3 : 2
... 45-45-90: 1 : 1 : √2
The long side of ΔMDX is 10√3, so the other two sides are
... MX = MD(√3/2) = 15
... DX = MD(1/2) = 5√3
The short side of ΔMNX is MX = 15, so the other two sides are
... NX = MX(1) = 15
... MN = MX(√2) = 15√2
Then the perimeter of ΔDMN is ...
... P = DM + MN + NX + XD
... P = 10√3 +15√2 + 15 + 5√3
... P = 15√3 +15√2 +15 . . . . perimeter of ΔDMN
Answer:
Keep the exact order that is shown
Step-by-step explanation:
The first exponential already has a point at (1, -2) which means the y-intercept would be less than -2, which is the lowest among the three
The second has a y-int at -2
Third has y-int at 2
Ratio and proportion
x/300=67/100
