Y = 1/2x + 3 on a graph

Answer:

Step-by-step explanation:

What is the question? If you want to know how to graph this equation, it's usually easiest to start with the intercepts, i.e., the points where the line crosses the axes.

y = ½x + 3 tells you that the line crosses the y-axis at (0,3), so plot that point.

Then let y = 0 and solve for x.

0 = ½x + 3

x = 6

The line crosses the x-axis at (6,0), so plot that point as well.

Then draw the line passing through those two points.

Malik is standing outside in the sun. Malik is 72 inches tall, and his shadow is 60

anastassius [24]

Jeremy's height is 67.2 inches

The diagram below represents situation

<h3>Proportion</h3>

Proportion says that two ratios (or fractions) are equal. This a mathematical comparison between numbers.

Therefore, let's establish the proportion in this situation

Malik height / Malik shadow = Jeremy height / Jeremy shadow

Therefore,

72 / 60 = x / 56

cross multiply

72 × 56 = 60x

60x = 4032

divide both sides by 60

x = 4032 / 60

x = 67.2

Therefore, Jeremy's height is 67.2 inches

Select the graph that correctly represents ƒ(x) = –2(x + 4)2 – 1.Find the equation of the parabola with its focus at (3,4) and i

IgorC [24]

Answer:

Equation of parabola: 8*(y - 2) = (x - 3)^2

y = (1/8)*(x - 3)^2 + 2

Step-by-step explanation:

focus at (3,4) and its directrix y = 0.

Focus equation: (h, k + c) = (3, 4)

Directrix equation y = k - c = 0

so h = 3, k + c = 4, k - c = 0

Solve the system : k + c = 4 and k - c = 0

add the equations together: k + c + k - c = 4 + 0

2k = 4

k = 2

so k + c = 4, 2 + c = 4, c = 2

4c (y - k) = (x - h)^2

4*2 *(y - 2) = (x - 3)^2

8*(y - 2) = (x - 3)^2
