Answer:

Yes

4x + 8y + 4x = 8x + 8y

8x + 8y = 8x + 8y

Answer:

Yes

Step-by-step explanation:

First, simplify the two expressions by using the distributive property:

4(x + 2y) + 4x

Distribute 4 to the terms in the parentheses:

4(x + 2y) + 4x

4x + 8y + 4x

Add like terms:

8x + 8y

Then, do this to the other expression:

8(x + y)

8x + 8y

So, both expressions are equal, because they both simplified to 8x + 8y

Jason Runs 100 yards in 15 seconds How Many feet can jason run in 15 seconds
SpyIntel [72]

Answer:

He can run 20 ft in 15 seconds

Step-by-step explanation:

we need to change yards to ft

3ft = 1yd

100 yds * 3ft/1yd = 300 ft

distance = rate * time

300 ft = rate * 15 seconds

divide by 15 seconds on both sides

300 ft/15 seconds = rate

20 ft/sec

He can run 20 ft in 15 seconds

Part 1: Graph piecewise functions from tables and equations.
marusya05 [52]
A.) 3.2 pounds package has a shipping cost of $4.13. We can't use the cost assigned to 3 lbs because the package is over 3 lbs but it is not over 4 lbs so we use the cost of 4lbs.

b) It is better to use a line graph where x values represent the weight in pounds and the y values represent the cost.

c) f(x) = 2.69 + 0.48(x-1)

d) domain is the x values; range is the y values

which of the folowing could be the equation for a parabola that opens to the left with vertex (-17, 2)
KATRIN_1 [288]

Answer:

x = a(y+17)^2 + 2 where a < 0

Step-by-step explanation:

Since the parabola is horizontal, the formula of the parabola is x = a(y-h)^2 + k where (h,k) is the vertex.

Since it opens to the left, a must be negative. The vertex is (-17, 2), so h = -17 and k = 2.

Substituting these in, we find that the equation is

x = a(y+17)^2 + 2 where a is a real number that is less than 0 (i.e. negative)

I hope this helps! :)
