Answer:

\mathsf {y =\frac{15}{7}x } < \mathsf {y=\frac{13}{6}x } < \mathsf {y=\frac{11}{5}x } < \mathsf {y=\frac{21}{9}x } < \mathsf {y= \frac{19}{8}x}

Step-by-step explanation:

<u>Finding the unit rate of the graph</u> :

  • Take 2 points and find the slope
  • ⇒ (0,0) and (12, 25)
  • ⇒ m = 25 - 0 / 12 - 0
  • ⇒ m = <u>25/12</u>
  • The equation is : <u>y = 25/12x</u>

Now, the equations with greater unit rates (in increasing order) are :

  • \mathsf {y =\frac{15}{7}x } < \mathsf {y=\frac{13}{6}x } < \mathsf {y=\frac{11}{5}x } < \mathsf {y=\frac{21}{9}x } < \mathsf {y= \frac{19}{8}x}

How do you solve 28-2.2x=11.6x-54.8??
malfutka [58]
28 - 2.2x = 11.6x - 54.8
28 + 54.8 = 11.6x + 2.2x
82.8 = 13.8x
82.8 / 13.8 = x
6 = x
or x = 6

Solve.<br><br> m - 15 = 20<br><br> m =
Fittoniya [83]

\text{Hello There!}

\text{We are going to need to isolate the variable}

m - 15 = 20

\text{Add 15 to both sides.}

\text{We do this because we need to perform inverse operations to find} \text{the value of the variable.}

m - 15 + 15 = 20 + 15 = 35

\fbox{Therefore, your answer is going to be 35.}

18. In the diagram below, PQRS is a square Find the equation of the circle that will pass through the four vertices of the squar
mamaluj [8]

An equation of the circle that will pass through the four (4) vertices of the square is (x + 2)² + y² = 2².

<h3>How to find the equation of this circle?</h3>

Mathematically, the general form of the equation of a circle is given by;

(x - h)² + (y - k)² = r²

Where:

  • h and k represents the coordinates at the center.
  • r is the radius of a circle.

<u>Note:</u> The center of a circle lies on the midpoint of the diagonal of a square, which is formed by joining its endpoints (opposite).

Midpoint on x-coordinate is given by:

Midpoint = (-2 - 2)/2

Midpoint = -4/2 = -2.

Midpoint on y-coordinate is given by:

Midpoint = (-2 + 2)/2

Midpoint = 0/2 = 0.

Thus, the center (h, k) = (-2, 0).

For the radius, we have:

r = √(-2)² + 0²

r = √4 = 2.

Substituting the parameters into the general equation, we have;

(x - (-2))² + (y - 0)² = 2²

(x + 2)² + y² = 2²
