Add EF and DE together to equal 32
2x-10 + 4x = 32
Combine like terms;
6x-10 = 32
Add 10 to each side:
6x = 42
Divide both sides by 6:
x = 42/6
X = 7
EF = 2x-10 = 2(7)-10 = 14-10 = 4
DE = 4x = 4(7) = 28
The third angle = 180 - 30 - 35 = 115 degrees
so its obtuse
Answer:
1. Is 8/15
Step-by-step explanation:
Answer:
0.8 or .8
Step-by-step explanation:
multiply the top and bottom by 10
so 8/10=80/100
to get the decimal form, just divide 8 by 10 and it should give you 0.8
Answer:
![y=0.5(x+1)^{2} -1.5](https://tex.z-dn.net/?f=y%3D0.5%28x%2B1%29%5E%7B2%7D%20-1.5)
Step-by-step explanation:
We know that,
The equation representing the quadratic function having the vertex ( h,k ) is given by
.
As, the vertex for the given system is ( -1,-1.5 ). We get the equation is,
.
Now, as the motorboat starts at ( 2,3 ). Substituting the values in above equation gives us,
.
i.e.
