A taxi service charges a flat fee of $1.25 and $0.75 per mile. if henri has $14.00, which of the following shows the number of m
andrey2020 [161]
Option m = 17

y = total cost of the service
m = number of miles run

y = 1.25 + 0.75 m

Equal the cost to the amount available by Henri

14 = 1.25 + 0.75m

Solve for m

m = (14 - 1.25)/0.75 = 12.75 / 0.75 = 17  miles.

Describe how you know that this is a proportional relationship
Deffense [45]

Answer:

(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") ... This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

Circle A is shown. Secant W Y intersects tangent Z Y at point Y outside of the circle. Secant W Y intersects circle A at point X
timama [110]

Circle A is missing, so i have attached it.

Answer:

∠XYZ = 35°

Step-by-step explanation:

We want to find the angle ∠XYZ in the image attached.

To solve that, we will use the formula in the theorem for angle formed by secants or tangents. Thus;

∠XYZ = ½(arc WZ - arc XZ)

From the image, arc WZ = 175° and arc XZ = 105°

Thus;

∠XYZ = ½(175 - 105)

∠XYZ = ½(70)

∠XYZ = 35°
