Answer:
given the equation y=3x-5 the slope would be 3
Step-by-step explanation:
looking at the equation you can see it is in y=mx+b form. this means that the coefficient next to the x is the slope
Table
x f(x)
-2 0.2
-1 0.4
0 0.8
1 1.6
2 3.2
Look that the pair of data (0, 0.8), it means f(0) is 0.8
Given
that a^0 = 1, means that the coefficient of the function has to be 0.8
and you discard the first and the third options.
You have to replace the values of x in the equations and compare the results.
For f(x) = 0.8 * (2^x) you get
x f(x) = 0.8 * (2^x)
-2 0.8 * (2^-2) = 0.8 / 4 = 0.2
-1 0.8 * (2^-1) = 0.8 / 2 = 0.4
0 0.8 * (2^0) = 0.8 * 1 = 0.8
1 0.8 * (2^1) = 0.8 * 2 = 1.6
2 0.8 * (2^2) = 0.8 * 4 = 3.2
As you can see these results are the same of the table of the question, so the function is f(x) = 0.8 (2^x).
Answer: f(x) = 0.8 * (2^x)
Answer: 2 terms
Step-by-step explanation:
There are two terms because
One is __x the other is the constant
9x + 4 - 3x + 7
6x + 4 - 7
6x - 3 has two terms
Answer:
Step-by-step explanation:
Multiplying a(x) and b(x) together results in a quadratic equation (a trinomial). This trinomial looks like (a·b)(x) = (2)(x - 2)(x + 2). Note that this is a "special product;" (2)(x^2 - 4); there is no middle term.
Step-by-step explanation:
Area of square
A = s²
A = 28²
A = 28 × 28
A = 784 cm²
