Answer:

f(-2) = +2

Step-by-step explanation:

Let x = -2

So,

f(x) = 4x + 10

Substituting the value of x gives ,

f(-2) = 4 × (-2) + 10 = 10 - 8 = 2

If m < 0 and b > 0, the graph of y = mx + b does not pass through which quadrant?

stiks02 [169]

Answer:

Quadrant III

Step-by-step explanation:

The attached picture shows graph of 4 such linear functions with the conditions given in the problem. ALL of them DO NOT pass through Quadrant III.

The graphs shown are of the functions:

$y=-2x+1$

$y=-3x+3$

$y=-x+0.5$

$y=-5x+2$

So, any linear function of the form $y=mx+b$ with $m$ and $b>0$ does not pass through Quadrant III. Answer choice 3 is correct.

Select the ordered pairs that satisfy the equation y=1/5x.Check all that apply.

vovikov84 [41]

Answer: C, E, F

Step-by-step explanation:

Plug in the "x" and "y" values from the ordered pairs into the equation.
For A: 3 = $\frac{1(5)}{5}$ → 3 ≠ 1 → A is eliminated.
For B: 5 = $\frac{1(1)}{5}$ → 5 ≠ $\frac{1}{5}$ → B is eliminated.
For C: 2 = $\frac{1(10)}{5}$ → 2 = 2 → C satisfies the equation.
For D: 10 = $\frac{1(4)}{5}$ → 10 ≠ $\frac{4}{5}$ → D is eliminated.
For E: -1 = $\frac{1(-5)}{5}$ → -1 = -1 → E satisfies the equation.
For F: 3 = $\frac{1(15)}{5}$ → 3 = 3 → F satisfies the equation.
Therefore, C, E, and F are the answers.

If f(x)=7x what is the inverse of f(x)

Brums [2.3K]

Answer:

f(x)=x/7

Step-by-step explanation:

f(x)=7x

y=7x

x=7y (switch y and x for inverse)

x=7y (isolate y)

x/7=y

The inverse of f(x)=7x is f(x)=x/7
