Suppose the light pattern from a fog light can be modeled by the equation x^2/25-y^2/9=1. One of the points on the graph of this equation is at (6,9.39/5), and one of the x-intercepts is -5. Which coordinate is not a point on the graph?

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
