Write the equation if the line that passes through (4,5) and has a slope of m=3
andrew11 [14]

Answer:

y = 3x - 7

Step-by-step explanation:

The <em>point-slope formula</em> for a straight line is

y – y₁ = m(x – x₁)

x₁ = 4; y₁ = 5; m = 3     Substitute the values

y – 5 = 3(x - 4)             Remove parentheses

y – 5 = 3x - 12             Add 5 to each side

     y = 3x - 7

The graph is a straight line with a y-intercept at y = -7 and a slope = 12/4 = 3.

Show Graph with the solution for 2x+3&gt;-9
kicyunya [14]

Answer:

I can't graph on this but x > -6

To graph you should draw a vertical (up and down) dotted line, and shade the graph to the right of the line.

Step-by-step explanation:

2x+3>-9    Subtract 3 from both sides of the inequality.

2x> -12      Divide both sides by 2

x> -6

A flagpole casts a showdown 15 feet long the 6 foot tall man casts a shadow 4 feet long how tall is the flag pole
Neko [114]
Set it up as a ratio:
mans shadow over mans height (4/6 ) equals flag pole shadow over flag pole height (15/x)

set them to equal each other:

4/6 = 15/x

cross multiply: 4*x =4x, 15*6 = 90

so you have 4x = 90

now divide both sides by 5 to solve for x, which is the height of the flag pole:

x = 90 / 4 = 22.5 feet tall

Let f = fish

If f < 12, let the fish go.

We cannot catch a fish measuring 11.99 inches.

If f = fish, then f < 11.99. It must be released.
