Answer:
x = -28
Step-by-step explanation:
−1/4x=7
Multiply each side by -4 to isolate the variable
-4 * −1/4x= -4*7
−1/4x=7
2x/5-x=20
2x=-100+20x
18x=100
x=50/9
You could use m= the lesser number and n as the greater number. Since one is 5 times the other you will start with m+5m=198. Then you will combine like terms so it will become 6m=198. Then you will solve it as a regular equation. m=33 and n=165.
Answer:

Step-by-step explanation:
If the left-side tiles are numbered 1–7 from top to bottom, their order on the right is ...
7 — denominators factored
6 — common factors canceled
5 — make the left side have the same denominator as the right
3 — express the sum over the common denominator
2 — collect numerator terms
Answer:
The absolute minimum value of the function over the interval [0,7] is -18.
Step-by-step explanation:
The given function is
Differentiate f(x) with respect to x.
Equate f'(x)=0 to find the critical points.
The critical point is x=3.
Differentiate f'(x) with respect to x.
Since f''(x)>0 for all values of x, therefore the critical point is the point of minima and the function has no absolute maximum value.
3 ∈ [0,7]
Substitute x=3 in the given function to find the absolute minimum value.
Therefore the absolute minimum value of the function over the interval [0,7] is -18.
