Simple...
you have:
-2x+5y=10
re-write in y=mx+b form...
-2x+5y=10
+2x +2x
5y=2x+10
Now divide....
5y=2x+10

y=

Now it's easy to see the slope and y-intercept...
Slope:

Y-intercept:2
Thus, your answer.
Answer:
- A → B: 1/3
- correct
- A → B: 2/5
Step-by-step explanation:
It is clear from your answer to the second part that you know the A→B scale factor is the reciprocal of the B→A scale factor. Use that fact for the other two parts of the question.
- A → B = 1/3; B → A = 3
- A → B = 2; B → A = 1/2
- A → B = 2/5; B → A = 5/2

It is convenient to find a unit length (or the smallest length) on the smaller figure, then see how much that is multiplied by to get the larger figure.
- B : A = 1 : 3
- A : B = 1 : 2
- B : A = 2 : 5
Once you have these ratios, you need to determine what the notation A→B is supposed to mean. Here, we presume it means B/A.
Answer: (g-f)(x)=-4x
Explanation: According to the graph, line created by function f(x) passes through the points (1,-3) and (0,0) and similarly, line created by the function passes through the points (1,1) and (0,0).
Thus, we can find the equation of the lines with help of formula
× 
so, equation of line created by function f(x)
y+3=
×(x-1)
y+3=
×(x-1)
y+3=-3x+3
y=-3x thus function f(x)=-3x
similarly, equation of line created by function g(x)
y=x thus function g(x)=x
Now, we have to find out, (g-f) (x)= g(x)-f(x)= -3x-x= -4x
Answer:
The surface area of the rectangular prism is 748 ft2.
Step-by-step explanation:
formula for surface area: A=2(wl+hl+hw)
A=2(wl+hl+hw)=2(5x16+14x16+14x5)=748
