+ y = -1 ⇒ y = - 1
To graph this line, plot a point at the y-intercept (0, -1), than plot the next point using the rise over run from the slope by counting up 1 and to the right 3 of the y-intercept. This gives you a second point of (3. 0). Draw a line through those two coordinates.
Answer: Plot (0, -1) and (3, 0) and draw a line through them.

y = 4 + ⇒ y = + 4
Same as above. Plot the y-intercept (0, 4) and then use rise over run from the slope to plot (3, 5).
Answer: Plot (0, 4) and (3, 5) and draw a line through them.

You should end up with two PARALLEL lines. Since the lines never intersect, there are no solutions to this system of equations.
Answer: No Solution
Answer: you wrote it wrong
Step-by-step explanation:
Answer:
The correct expression is
The value when is
Step-by-step explanation:
Let
x------> a number
we know that
The algebraic expression of “two less than the quotient of a number cubed and sixteen, increased by eight” is equal to
For
Substitute the value of n in the expression
so
The value when is
First you would take 321 and subtract 5
316
they you would divide by 2
158
there are 158 boys
to find the # of girls take 158 and add 5
163
Answer : option C
We analyze the attached graph
First, Ricky walked away from mall at the constant speed for 30 seconds
Second, he stopped walking for 40 seconds
Third, he walked towards mall at a constant speed for 10 seconds
Fourth , both walked away for next 20 seconds
So total walk time = 30 + 40 + 10 + 20= 100 seconds
Total time is 100 seconds. so we cannot choose option B and d because the graph ends before 100 seconds.
In option A, Ricky walked away from the mall after 70 seconds. so we cannot choose option A.
Option C is the graph best represents Ricky's motion.
