Answer:
y = x - 4
Step-by-step explanation:
<u>Use point slope form: (y - y1) = m(x - x1)</u>
m = 1
<u>Step 1: Plug in</u>
(y - (-3)) = 1(x - 1)
y + 3 - 3 = x - 1 - 3
y = x - 4
Answer: y = x - 4
The correct answer is the 5th option (one before the last one).
In order to check whether the length of the sides are applicable to form a triangle is that we have to make sure that the sum of the length of two side should be greater than the third side.
<span>18.5 m, 36.9 m, and 16.9 m
18.5 m < </span><span>36.9 m +16.9 m
</span>36.9 m < 18.5<span> m +16.9 m
</span>16.9 m < 18.5 m + <span>36.9 </span>m
So the dimensions are correct!
Y=x^2-5
y=2x-5
y+5=2x
x=(y+5)/2
y=((y+5)/2)^2-5
y=(y^2+10y+25)/4-5
4y=y^2+10y+25-20
0=y^2+6y+5
0=(y+5)(y+1)
y= -5 or -1
y=2x-5 (y= -5 doesn't work for this one so use -1)
-1=2x-5
2x=4
x=2
Using these answers, you can choose answer D with reasonable certainty.
Solve for x by simplifying both sides of the equation, then isolating the variable.
Exact Form: x= 2/5
Decimal Form: x= 0.4
