Answer:

x = 3, y = 2

Step-by-step explanation:

Substitute the values of x from each alternative in the previous question, then solve for y. This is depicted below.

A. y = -7, x = 5, 4(5) + 2y + 3 = 19
B. y = 0 and x = 4, 4(4) + 2y + 3 = 19
C. y = 2 and x = 3, 4(3) + 2y + 3 = 1
D. y = 4, x = 2, 4(2) + 2y + 3 = 19

Only the third option has a y value that is comparable to the value in the computations, according to the calculations.

As a result, the letter C is the correct response.

From the hay loft door, Ted sees his dog on the ground. The angle of depression of the dog is 40º. Ted's eye level is 16 feet ab

Vlad1618 [11]

Answer: 19 feet

Step-by-step explanation:

Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.

Tan α = opposite side / adjacent side

Where α is the angle of depression of the dog, the opposite side (16) is Ted's eye level above the ground, and the adjacent side (x) is the distance between the dog and the barn door.

Replacing with the values given:

tan40 = 16/x

Solving for x

x =16/tan40

x= 19 ft

What must be added to x² + 6x²-x+ 5 to make it exact divisible by (x + 3)

maxonik [38]

Let f(x) = x² + 6x²-x+ 5 then ,

number to be added be P

then,

f(x) = x² + 6x²-x+ 5 +P

According to the qn,

(x+3) is exactly divisible by zero then,

R=0

comparing .. we get a= -3

now by remainder theorm

R=f(a)

0=f(-3)

0=(-3)² + 6(-3)²-(-3)+ 5 + P

0= 9 + 54 + 3 + 5 + P

-71=P

therefore, -71 should be added.

Hope you understand

ILL MARK AS BRAINLIST IF U GET IT RIGHT it’s khan

Sergeeva-Olga [200]

Answer:

Step-by-step explanation:

given that x and y are proportional, they can be expressed as y = rx, where r is the proportionality constant. Thus, we can solve for r by doing y/x in any given point.

$\frac{8}{1.6} = \frac{15}{3} = \frac{22}{4.4} = 5$
