Answer:
y=-2/7x+6
Step-by-step explanation:
first write this in y=mx+b format, y=7/2x−2
then write the perpendicular line, which is the opposite & negative of m
y=−2/7x-2
then remove b
y=−2/7x+b
plug in the numbers
(7,4) y= 4 x=7
4=-2/7*7+b
b is 6
so put the numbers back in
y=-2/7x+6
hope this helps and have a great day

Answer:
x = 45°
Step-by-step explanation:
<u>Vertical Angle Theorem</u>
When two <u>straight lines intersect</u>, they form two pairs of angles. The vertically opposite (non-adjacent) angles are <u>congruent</u> (equal).
From inspection of the given diagram, the <u>straight line with points C and D</u> and the <u>straight line with points F and G</u> intersect at <u>point E</u>.
Therefore, angles ∠FEC and ∠DEG are vertically opposite, and so they are equal.
From inspection of the diagram:
- ∠FEC = x°
- ∠DEG = 20° + 25° = 45°
Therefore:
⇒ ∠FEC =∠DEG
⇒ x = 45°
Answer:
Time, t = 4.5 s
Step-by-step explanation:
The number of seconds t it takes the ball to hit the green can be represented by the equation :
It means that the initial velocity is 70 ft/s. The above equation becomes:
It is required to find the time taken by the ball to land on the ground. It is a quadratic equation. The solution of quadratic equation is given by :
t = −0.125 and t = 4.5 s
Time cannot be negative. So, the time taken by the ball to land on the ground is 4.5 seconds.
