Answer:
(9,-2)
Step-by-step explanation:
5 is the x coordinate, and 4 is the y coordinate. When you go right a certain amount of units, you add those units to your x coordinate. If you were to go left a certain amount of units, you'd subtract them. Since we're going right, 5 + 4 = 9. When you go up a certain amount of units, you add those units to you y coordinate. If you were to go down a certain amount of units, you'd subtract them. Since we're going up, -6 + 4 = -2. So, x = 9 and y = -2, or (9,-2)
3x + 28
We can combine 7x and -4x because they are like terms. 7x -4x is equal to 3x. Now we rewrite the expression as 3x + 28.
Answer:
∴73,563 calls are made between two cities with populations of 100,000 and 160,000 that are 435 miles apart.
Step-by-step explanation:
Given that,
The number of phone calls between two cities (N )
- directly proportional as the value of populations
and 
of two cities. - Inversely varies as the magnitude of distance (d).
Given that,
N=18,000, d=310 miles, =15,500 and =180,000
Now,
N=? , d=435 miles, =100,500 and =160,000
∴73,563 calls are made between two cities with populations of 100,000 and 160,000 that are 435 miles apart.
Answer:
36.87°
Step-by-step explanation:
Since ABC is a right-angle triangle, we can use trigonometric ratios to solve for unknown angles and sides.
For Angle at A, we have lengths of opposite and adjacent sides so we can use tangent at A.
tan(A) = opposite/adjacent
tan(A) = CB/AB
tan(A) = 6/8
A = (tan^-1)(0.75)
A = 36.86989765°
A is your answer hope this helps
