Answer:

Step-by-step explanation:

8q+6=4q-14

minus 4q from both sides to get

4q+6=-14

-6 from both sides

4q=-20

divide by 4

q=-5

we can check if this is right by implementing -5 as a substitute for q

-40+6=-20-14

-34=-34

Based on the family the graph below belongs to, which equation could represent the graph?

lord [1]

Answer-

Equation 1 is the equation which represents the graph.

Solution-

From the graph it can be noticed that, the function is a hyperbola. It is a rectangular hyperbola.

The general form of rectangular hyperbola is,

$xy=c^2$

Where c is a constant.

Equation 1 represents a function of rectangular hyperbola, with vertical asymptote as x=-2 .

Equation 2 represents an exponential function.

Equation 2 represents an cubic function.

Equation 2 represents logarithmic function.

Therefore, equation 1 is the equation which represents the graph.

Francine Flicka found a bargain when she bought a lawn mower. She paid the store's clerk three $20 bills and received him $7.45

adoni [48]

Answer:

$48.97

Step-by-step explanation:

Let p represent the marked price of the mower. Then the price with tax is ...

with tax = p + 7.3%×p = 1.073p

The amount Flicka paid is the amount tendered less the change she received, so is ...

3×$20 - 7.45 = with tax = 1.073p

To find p, we can divide by its coefficient:

(3 × $20 - 7.45)/1.073 = p ≈ $48.97

The selling price before taxes was $48.97.

_____

Comment on the problem

If you check the answer, you find the amount with tax is ...

$48.97 × 1.073 ≈ $52.54481 ≈ $52.54

so the change Flicka would have received would have been $7.46, not $7.45. If the price were $48.98, then the change would have been $7.44. There is no price at which the mower can be marked that will make the total with tax come to $52.55. There is no solution to this problem.
