Write an equation in slope-intercept form for the line that has a slope of -4/5 and passes through (0, 7).
patriot [66]

Answer:

A. y = -\frac{4}{5}x + 7

Step-by-step explanation:

Slope intercept form is y = mx + b where m is the slope and b is the y-intercept

<em>It gives us the slope, so we can plug that in:</em> y = -\frac{4}{5}x + b

<em>Next, it gives us a point, so we can plug in the x and y into our equation and solve for b when (x, y)</em>

y = -\frac{4}{5}x + b

7 =  -\frac{4}{5}(0) + b

7 = b

<em>Last, complete our equation:</em>

y = -\frac{4}{5}x + b

y = -\frac{4}{5}x + 7

The local public pool is a rectangle with two semicircles.
Reptile [31]

The area of the surface of the pool is 7322.64 m².

<h3>What is Area of rectangle?</h3>

The area of rectangle is product of length and its breadth.

i.e., length * breadth

Given: Length = 100 m, Width = 52 m and Diameter = 52 m

Area of rectangle,

= 100 × 52

= 5200 m²

Now,

Area of semicircle = 1/2 × πr²

=1/2 × 3.14 × 26²

= 1061.32 m²

Hence, area of the surface of the pool is

= 1061.32 + 1061.32 + 5200

= 7322.64 m²

Answer:

C. {-5,-4, -3, 1, 2, 5}

Step by step explanation:

We have been given a graph and we are asked to find the domain of the relation represented in graph.

We can see that our graph is a series of unconnected points. Our function represents integer values. So we can see that our graph represents a discrete function.    

Since we know that domain of a discrete function is set of inputs values consisting of only certain values in an interval. .

The set of first value from each of the given points would made domain of our function. Upon looking at our graph we can see that domain of our function is -5,-4, -3, 1, 2 and 5.  

Therefore, option C is the correct choice.
