Answer:
F. 6s > 4s +8
Step-by-step explanation:
From a reference point at the beginning of the track, Ward's car will be located 4s+8 feet down the track after s seconds. That is, it starts 8 feet down the track, and increases its distance by 4 feet every second.
From the same reference point, Heskey's car will be located 6s feet down the track after s seconds. Its distance starts from zero and is increasing at the rate of 6 feet every second.
For Heskey's distance to exceed Ward's distance you want ...
6s > 4s +8 . . . . . . matches choice F
f(x)= -2x-3
Step-by-step explanation:
Step 1:
Let the sequence given here is -5, -7, -9, -11, -13 ......
Here the first term (a₁) of sequence is -5
And the common difference between the numbers in the sequence is
d= (-7-(-5)) = -7+5 = -2
Let the number of terms be x
Step 2;
To find the sequence function basic arithmetic sequence formula is
aₙ = a₁ + d( x-1)
Applying the values we get
f(X) = -5 + ((-2)(X-1))
on simplification
f(X) = -5 + (-2X+2)
f(X)= -5+2-2X
f(X)= -3-2X
Step-by-step explanation:
Since, Point E is the midpoint of DF
Therefore,
DE = EF
10x = 4x + 12
10x - 4x = 12
6x = 12
x = 12/6
x = 2
EF = 4x + 12 = 4*2+12 = 8 * 12 = 20
EF = 20
AB = BC
6x + 2 = 9x - 10
10 + 2 = 9x - 6x
12 = 3x
12/3 = x
x = 4
BC = 9x - 10 = 9*4 - 10 = 36 - 10 = 26
Answer:
It would be A
Step-by-step explanation:
If you are minusing by 5 in the equation then that means that they graph has gone down by 5 units not up. and since 4x and is positive and -2x is negative the graph would flip over the years axis
Circumference = 2 x pi x radius
2 x pi x 4 = 25.13 yards
(correct to 2 decimal places)
Hope this helps!!
