Answer:
y=7x-188
Step-by-step explanation:
We know that this line must have a slope of 7, because this line is parallel to y=7x+13
We must use the point slope formula: y-= m(x-
)
Next, we will plug in the point (28,8) for and
, and 7 in for m
y-8=7(x-28)
Solve the equation, first by distributing the 7
y-8=7x-196
Add the 8 over
y=7x-188
Answer:
Inequality is
Solution is C: t > 82
Step-by-step explanation:
Let the number of tickets = t
It is given that the committee earns $4 per ticket. That is, they earn dollars.
Also, the committee earns $72 from the bake sale.
So, the total income is dollars.
Since, the dance will cost $400.
So, the total earning must be greater than $400.
Thus, the inequality for the situation is given by, .
So, on solving, we have,
i.e.
i.e. t > 82.
Thus, the solution of the inequality is
Hence, option C is correct.
