Answer:
Its positive
Step-by-step explanation:
3x - 5 = -3
3x = 2
x = 2/3
2/3 is positive
Answer:
Step-by-step explanation:
This is classic right triangle trig. The height of the hill is 78.4 which serves as the side opposite the reference angle of 23 degrees. The side we are looking for is the hypotenuse of that triangle. The trig ratio that relates the side opposite a reference angle to the hypotenuse of the right triangle is the sin ratio. Setting it up using our values:
, where x is the unknown length of the hypotenuse. Solving for x:
Make sure your calculator is in degree mode before entering this in. You will get a length of the hypotenuse as 200.649 feet, so choice A.
<em>Length = </em><em>80</em>
<em>Breadth = </em><em>30</em><em> </em>
<em>Height = </em><em>30</em>
<em>Total surface area of a cuboid is= </em>
<em><u>2 ( lb + bh + hl )</u></em>
<em>Putting the values in the formula,</em>
<em>We get,</em>
<em>= 2</em><em> [</em><em> (80 x 30) + (30 x 30) + (30 x 80)</em><em>]</em>
<em>= 2 (2400 + 900 + 2400)</em>
<em>= </em><em><u>8100 cm²</u></em>

You said each equation but only posted one.
The standard form takes the place of
Ax + By = C.
y-5 = -3(x+2)
y - 5 = -3x - 6
y = -3x - 6 + 5
3x + y = -1
Done.
(f∘g)(x) is equivalent to f(g(x)). We solve this problem just as we solve f(x). But since it asks us to find out f(g(x)), in f(x), each time we encounter x, we replace it with g(x).
In the above problem, f(x)=x+3.
Therefore, f(g(x))=g(x)+3.
⇒(f∘g)(x)=2x−7+3
⇒(f∘g)(x)=2x−4
Basically, write the g(x) equation where you see the x in the f(x) equation.
f∘g(x)=(g(x))+3 Replace g(x) with the equation
f∘g(x)=(2x−7)+3
f∘g(x)=2x−7+3 we just took away the parentheses
f∘g(x)=2x−4 Because the −7+3=4
This is it
g∘f(x) would be the other way around
g∘f(x)=2(x+3)−7
now you have to multiply what is inside parentheses by 2 because thats whats directly in front of them.
g∘f(x)=2x+6−7
Next, +6−7=−1
g∘f(x)=2x−1
Its a lts easier than you think!
Hope this helped
