Answer is A. 3 1/4 is to the left of 7/2 and 7/2 is to the left of 3.75.
With a horizontal line, they are talking about the integers from positive to negative. as you go left the numbers decrease and as you go right the numbers increase
First change 3 1/4 and 7/2 into decimals
3 1/4= 3.25
7/2= 3 1/2= 3.5
Here are your decimals from least to greatest.
3.25, 3.5, 3.75
So 3.25 (3 1/4) is to the left of 3.5 (7/2) and it is to the left of 3.75
To factor a quadratic of the form ax^2+bx+c you need to find two values, j and k, that satisfy two conditions:
ac=jk and b=j+k in this case:
ac=jk=-18 and b=j+k=7 so j and k must be 9 and -2
Now replace bx with jx and kx in the original equation...
x^2-2x+9x-18 and factor the 1st and 2nd pair of terms...
x(x-2)+9(x-2) which is equal to
(x+9)(x-2)
Answer:
X) x=−2−7yi/8+i/8
Y)y=8xi/7+1/7+16i/7
Step-by-step explanation:
Answer:
The direct distance from the plane to the start of the runway is approximately 5.0623 km
Step-by-step explanation:
The locations of the beacons on the runway, x = 5 km from the start of each runway
The angle of elevation of the airplane from the runway, θ = 9°
Let 'R' represent the direct distance from the plane to the start of the runway
The horizontal distance from the start of the runway to the beacon, 'x', the distance from the plane to the start of the runway, 'R', and the vertical height of the plane, 'h' form a right triangle with rides x, R, and h
By trigonometric ratios, we have;

Therefore, we have;

From which we have;

The direct distance from the plane to the start of the runway, R ≈ 5.0623 km
