Answer:
Formula for nth term in Arithmetic sequences is:
where a is the first term, d is the common difference and n is the number of terms.
As per the statement:
The rule for the pattern is add 4.
As the first term in line says the first term i,e 7
common difference(d)= 7
As the Jenna number is 8th in line.
Series we get;
7, 11, .........
We have to find the 8th term.
n = 8, a = 7 and d = 4
Using above formula:
Therefore, 35 number should Jenna say.
Answer:
The correct answer is D

-20 is your y-intercept and your graph will be increasing
Answer:
The truck travel must to have a constant speed of 
Step-by-step explanation:
we have
where
d expresses a car's distance in feet
t is the number of seconds
<em>Find the distance d for t=8 sec</em>
<em>Find the distance d for t=8.2 sec</em>
The total distance in this interval of 0.2 sec is
<em>Find the speed of the car</em>
Divide the total distance by the time
therefore
The truck travel must to have a constant speed of

Let's solve your equation step-by-step.
x2+x=12
Step 1: Subtract 12 from both sides.
x2+x−12=12−12
x2+x−12=0
Step 2: Factor left side of equation.
(x−3)(x+4)=0
Step 3: Set factors equal to 0.
x−3=0 or x+4=0
x=3 or x=−4
Answer:
x=3 or x=−4
