Answer:
v = - 3
Step-by-step explanation:
Given
v = u + at ← substitute u = 2, a = - 5, t = 1 into the expression
v = 2 + (- 5 × 1) = 2 + (- 5) = 2 - 5 = - 3
Answer:
3.5x + 15 ≥ 55
Step-by-step explanation:
I think the question below contains the missing information.
<em>Josh has a rewards card for a movie theater. - He receives 15 points for becoming a rewards card holder. - He earns 3.5 points for each visit to the movie theatre. - He needs at least 55 points to earn a free movie ticket. Which inequality can Josh use to determine x, the minimum number of visits he needs to earn his firs free movie ticket?
</em>
My answer:
- Becoming a member = 15 points
- Visiting the moving theater = 3.5 points
- Total points needed for a free movie ticket = 55
Let x is the number of times he visits = 3.5x
Total points = Points received on becoming a member + Points received on x visits
So,
Total Points = 15 + 3.5x
We know the total points must be at least 55 for a free movie ticket. This can be expressed as:
3.5x + 15 ≥ 55
Answer:
The roots are


Step-by-step explanation:
we have

so
Group terms that contain the same variable, and move the constant to the opposite side of the equation


Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side



Rewrite as perfect squares

square root both sides



Answer:
y=2x
Step-by-step explanation:
y=mx+b
If it crosses through the point (0,0) it means that the y intercept (b) is 0.
m=slope
Not sure how to show you the graph but it is simply a diagonal line through (0,0) that will hit (1,2), (2,4), etc.
