Answer:

The answer is: 5.

Step-by-step explanation:

Set up an equation:

2 / 7 = y / 17.5

Cross multiply:

7y = 2 * 17.5

7y = 35

y = 35 / 7 = 5

Answer:

y = 5.

Step-by-step explanation:

Direct proportionality is : y = kx where k is a constant.

Finding k by substituting the given values of x and y:

2 = k * 7

k = 2/7.

So the equation is y = 2/7 x.

When x = 17.5:

y = 2/7 * 17.5

y = 5.

Lamar used a coordinate plane to show where his posters are displayed on his bedroom wall. Three posters are located at Q(4, 2),
iren2701 [21]

Answer:

Distance between the points Q and R is 1 unit while the distance between the points R and S is 3 units

Step-by-step explanation:

Here, we want to use the absolute value of the coordinates to find the distances.

Since we are using absolute values, the negative points becomes positive;

Thus;

Q = (4,2)

R = (3,2)

S = (3,5)

Mathematically, the distance between two points in the Cartesian plane can be calculated using the formula;

D = √(x2-x1)^2 + (y2-y1)^2

The distance QR is thus;

D = √(3-4)^2 + (2-2)^2

D = √(-1)^2 + 0

D = √1 = 1 unit

The distance RS is thus;

D = √(3-3)^2 + (5-2)^2

D = √(0) + (9)

D = √9 = 3 units
