Answer:

Step-by-step explanation:

Solve for h.

h - 6 = 7

h = 7 + 6

h = 13

------------------

check

13 - 6 = 7

7 = 7

the answer is good

So, this one is pretty easy. Since h-6=7, you just add 6 and 7 and subtract 6 to find the answer, like this.

6+7=13

13-6=7

and h=13

Easy, huh?

Jason works at least 5 hours but not more than 10. He earns $15.00 per hour. The function f(x) = 15t represents the money he ear

frosja888 [35]

Answer:

Step-by-step explanation:

The amount of money that Jason earns is dependent on the amount of time, t in hours that he works

The function f(x) = 15t represents the money he earns for working t hours. Therefore, the dependent variable is f(x) and the independent variable is t

Jason works at least 5 hours but not more than 10. This means that The minimum amount that he can earn is 15×5 = $75

The maximum amount that he can earn is 15×10 = $150

The practical domain is all possible values for t. It becomes

5 lesser than or equal to t lesser than or equal to 10

The practical range is all possible values for f(x). It becomes

75 lesser than or equal to f(x) lesser than or equal to 150

URGENT!!! Which is a y-intercept of the graphed function?

dexar [7]

The y-intercept is where the graph goes through the y-axis (the vertical line in the center). It goes through at y=-9, so the coordinates would be (0,-9), since it is (x,y).

A parabola can be represented by the equation x2 = 2y. What are the coordinates of the focus and the equation of the directrix?

Airida [17]

Answer:

i) Focus ( 0,a) = $(0,\frac{1}{2} )$

ii) The equation of the directrix is

$y = -\frac{1}{2} or y +\frac{1}{2} =0$

Step-by-step explanation:

Step(i):-

A parabola is the set of all points in a plane that are equidistant from a fixed line and a fixed point (not in a line) in the plane

• The Fixed line is called the directrix of the parabola.

• The Fixed point is called the focus of the parabola.

• A line through the focus and perpendicular to the directrix is called the axis of the parabola.

• The point of intersection of parabola with the axis is called the vertex of the parabola.

Given Parabola x² = 2 y

Comparing x² = 4 a y

4 a = 2

$a = \frac{1}{2}$

Focus ( 0,a) = $(0,\frac{1}{2} )$

Step(ii)

The equation of the directrix is y = -a or y +a=0

The equation of the directrix is

$y = -\frac{1}{2} or y +\frac{1}{2} =0$

The equation of the directrix is 2 y +1 =0
