The linear function rule is d = 103t
<h3>What Speed is?</h3>
The ratio of the distance travelled to the time taken is known as speed.
The formula for calculating the distance traveled is expressed as:
Speed = 618ft/6s
Speed = 103ft/s
Recall that:
d = st
Substitute s = 103 into the expression to have:
d = 103t
Hence the linear function rule is d = 103t

(8r+3s)(8r-3s) dont have working but noticed that it is the difference of two squares
Answer:
y < 8
Step-by-step explanation:
First, distribute that -3 over (3y + 4), obtaining -9y - 12 < -12y + 12.
Next, add 12y to both sides, obtaining 3y - 12 < 12, or 3y < 24
Then y < 8 must be true.
Answer:
x = 81, y = 68 and z = 99
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
z is an exterior angle, thus
z = 63 + 36 = 99
x and z form a straight angle and are supplementary, so
x + z = 180, that is
x + 99 = 180 ( subtract 99 from both sides )
x = 81
The sum of the 3 angles in a triangle = 180°, thus
z + y + 13 = 180, that is
99 + y + 13 = 180
112 + y = 180 ( subtract 112 from both sides )
y = 68
