Answer:

y

Step-by-step explanation:

First, let's find the equation of the line.

From the graph, we can pick out two points to use: (0,1) (the y-intercept) and (4,0) (the x-intercept).

Find the slope. Let (0,1) be x₁ and y₁ and let (4,0) be x₂ and y₂

Find the slope:

m=\frac{y_2-y_1}{x_2-x_1}

Substitute:

m=\frac{0-1}{4-0}\\m=-1/4

Use the slope-intercept form:

y=mx+b

Where m is the slope and b is the y-intercept.

We already know the slope is -1/4 and the y-intercept is 1. So, substitute:

y=-\frac{1}{4}x+1

Now, replace the equal sign with an inequality. Note that the line is dotted, so we won't use "or equal to." Also note that the blue, shaded area is <em>below</em> the line. Thus, we will use less than. Therefore:

y

The sentences:

First, we picked out two points from the graph. Next, we used those two points to find the slope. We used the slope and one of the points to write our slope-intercept equation. Afterwards, we can determine from the graph that since the shaded area is below the dotted line, the equation must have a less than.

Answer:

y < -1/4 x +1

Step-by-step explanation:

Find two points on the dotted line

( 0,1) and  (4,0)

We can use the slope formula

m = ( y2-y1)/(x2-x1)

    = (0-1)/(4-0)

    = -1/4

The slope is -1/4

The y intercept is where it crosses the y axis  or 1

The equation of the line, using slope intercept form

y = mx+b

y = -1/4x +1

The line is dotted which means there is no equals, just greater than or less than.  It is shaded below which means less than

y < -1/4 x +1

The domain for f(x) is all real numbers greater than or equal to ___ ?
Shkiper50 [21]
You must set each part of the function equal to zero.

5√(x+2) = x is greater than or equal to -2

So the domain is greater than or equal to -2

Pythagorean theorem calc: find c, a=12.96148, b=11
eduard
A = 12.96148 b = 11
a^2 + b^2 = c^2
(12.96148)^2 + (11)^2 = c^2
168 + 121 = c^2
289 = c^2
c = sqrt(289)
c = 17 I did a little bit of rounding to get this, but I'm sure it is close enough.

Please help will give brainliest
Bezzdna [24]

From 8:25 am to 30 seconds past 8:29 am, there are 4.5 minutes. Her speed is calculated by dividing the distance of the post office from her house by the time.

         Speed = 0.75 mile / 4.5 minutes = 1/6 mile / minute

Determining the number of minutes she will have to take in order to reach school,

         Time = 3.42 mile / (1/6 mile/minute) = 20.52 minutes

Adding this to the initial time,

           Final time = 8:25 am + 20.52 minutes

                    = 8:45 am and 31.2 seconds.

She will reach the school on time even without increasing her speed.
