Step-by-step explanation:
let the speed of diesel train = x
the equation would be:
(2+6)x = 6(x+15)
8x = 6x+90
8x-6x = 90
2x = 90
x = 90/2
x = 45
Therefore, the speed of diesel train =
45 mph

Prove segment GF = segment HF
Answer:
GF = FH
Step-by-step explanation:
GEF & FIH
EF = FI (equal)
GEF = FIH (alternate angle)
EG = HI (parallel sides equal)
GEF & FIH are congruent, under the case of (SAS)
therefore, GF = FH (corresponding angle)
Make s the subiect of v2 = U2+ 2as
Answer:
v2=U2+2as
v2-U2=U2-U2+2as
v2-U2=2as
(v2-U2)/2a=2as/2a
v2-U2/2a=s
s=(v2-U2)/2a

Five triangles are shown on the coordinate plane.
Which triangle is a possible reflection of triangle A?
Answer:
answer choice c!
Step-by-step explanation:
hope this helps!
A reflection is when you "flip" the shape across the axis.
Choice C would work because you can flip triangle a and make d over the x axis

How do I Evaluate (−9)²
Answer:
81
Step-by-step explanation:
you evaluate by mutiplying the number with the exponent, which is -9 multiplied by -9, which is 81 because 2 negatives multipled or divided is a positive. hope this helped a bit
Answer:
81
Step-by-step explanation:
Here, some steps to evaluate (-9)².
Step 1 :- A negative base raised to an even powers equal positive.
9 ²Step 2 :- Write exponentiation as multiplicaton.
9 × 9Step 3 :- Multiply it .
81Another way to evaluate ( -9 ) ².
Evaluate by multiply with it's exponent.
-9 × -9When two negative sign combine they formed positive
So, after multiplying we get 81.

The composition of function f ( x ) / g ( x ) = -x² + x - 1
What is Composition of functions?Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.
Given data ,
Let the first function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = x⁴ - x³ + x²
Let the second function be represented as g ( x )
Now , the value of g ( x ) is
g ( x ) = -x²
Now , the composition of function is ( f/g ) ( x )
On simplifying , we get
( f/g ) ( x ) = f ( x ) / g ( x )
f ( x ) / g ( x ) = x⁴ - x³ + x² / -x²
f ( x ) / g ( x ) = -x² + x - 1
Hence , the function is A = -x² + x - 1

Explain how to evaluate
(-9)(-6)(15)(–7 + 7)
as simply as possible.
Hey there!
(-9)(-6)(15)(-7 + 7)
[-9(-6) = 54]
= 54(15)(-7 + 7)
[54(15) = 810]
= 810(-7 + 7)
[-7 + 7 = 0]
= 810(0)
