Step-by-step explanation:
<h3>#1</h3>
- 15 ⋅ 6 - 2² ⋅ 8 + 4³ =
- 15 ⋅ 6 - 4 · 8 + 64 =
- 90 - 32 + 64 =
- 58 + 64 =
- 122
<h3>#2</h3>
- 2³ + 2² ⋅ 2 + 6 - 2¹ ⋅ 2⁰ - 1 =
- 8 + 4 · 2 + 6 - 2 · 1 - 1 =
- 8 + 8 + 6 - 2 - 1 =
- 22 - 2 - 1 =
- 20 - 1 =
- 19
Answer:
x = 8
y = 3
Step-by-step explanation:
x + y = 11
x - y = 5 Subtract
2x = 16
x = 16/2
x = 8
x + y = 11 Substitute x = 8
8 + y = 11 Subtract 8 from both sides
8-8+y =11-8
y = 3
3x + 5=26
subtract 5 from both sides
3x=21
divide by 3
x=7
The A(n) is inverse function is the function that sometimes results when the independent variable of a function is exchanged with the dependent variable.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We know that the inverse of a function, sometimes known as an anti function, is a function that can be reversed into another.
In other words, if a function "f" converts x to y, the inverse of the same function will convert y to x. The inverse function is denoted by f⁻¹ or F⁻¹ if the function is denoted by 'f' or 'F'.
Thus, the A(n) is inverse function is the function that sometimes results when the independent variable of a function is exchanged with the dependent variable.

Answer:
15
Step-by-step explanation:
Take 62.5 from 100 = 37.5
divide this by 100 = 0.375
times 40 by this
0.375 x 40 = 15
