Four more than the product of a number and 3 equals 7.

The phrase you typed can be written in mathematical form using a replacement of "a number" with the letter "x" (for our unknown).

So we can translate in mathematical form as shown below:

"<em>four more than the product of a number and 3 equals 7</em>"

x * 3 + 4 = 7

and of course we can solve this equation by operating with thenumbers so as to isolate the unknown "x"on one side of the equal sign:

Subtract 4 from both sides:

x * 3 = 7 - 4

x * 3 = 3

Divide both sides by 3 (so as to eliminate the factor 3 multiplying x):

x = 3 / 3

x = 1

And our answer is that the unknown number is 1 (one).

H = hrs she worked
p = phone calls she answered

h x 10 + p x .25 = maggies earnings

Part A
h x 10 + 60 x .25 = 115

Part B
h x 10 + 15 = 115 (multiplied 60 x .25)
h x10 = 100 (subtracted 15 from each side of the equation)
h = 10 (divided 10 into each side)

Part C

Which inequality is shown in the graph?
sergij07 [2.7K]

Answer:

The answer to your question is: letter C

Step-by-step explanation:

Data

Find the Parabola's equation and express the equation as an inequality.

Vertex = (0, -5)

Equation

                               (x- h) ² = 4p(y - k)

                               x² = y + 5

                              y = x² - 5

But, we need the area upper the parabola, then

                              y ≥ x² - 5
