Grace needs $45 to go to Six Flags. She has $13. She earns $8 an hour walking dogs. Which
agasfer [191]

Answer: C. 13 + 8x = 45

Step-by-step explanation:

She already has 13 dollars. This would be the b-value in the equation, thus eliminating options A and B because those two feature 13 as the m value.

She earns $8 per hour. Let x = number of hours walking dogs.

Since 8 is the slope, it would be attached to x, thus either C or D would be the correct response

Since Grace is adding 8 dollars per hour, not subtracting, D is incorrect, leaving C to be the correct answer.

PLS HELP ME ASAP I ONLY HAVE 5 MINITUES
Shkiper50 [21]

Answer:

200 + 50x = 450

Step-by-step explanation:

So, 200 + 50x = 450

50x = 450-200 = 250

X = 250/50

X = 5

Check:

200 + 50(5)

= 200 + 250 = 450.

For a birthday party you need to cut two submarine sandwiches into smaller pieces of equal length for your friends.one sandwich
vovangra [49]

Answer:

4 inches

Step-by-step explanation:

Let us assume that there are few numbers of friends.

Therefore, 28 inches of one sandwich has to be divided into equal few pieces and another 36 inches of the sandwich has to be divided into equal few pieces.

We have to calculate the greatest possible length of the pieces.

Therefore, the greatest length of each piece will be a common factor of 28 and 36.  

Now, we have 28 =2×2×7 and 36 =2×2×3×3. Hence, the greatest possible factor is 2×2 = 4.

Therefore, greatest possible length of each piece of the sandwich is 4 inches. (Answer)

How does a change in the value of h effect the axis of symmetry of the graph ? How does the value of k change the axis of symmet
Ber [7]

The value of h is exactly the axis of symmetry. So when h changes, it completely changes the line of symmetry. This is because the vertex is (h, k) and the x value of the vertex is always equal to the line of symmetry in a quadratic.

Changing the k value does nothing to the line of symmetry. This is because it is just moving the graph up and down, which doesn't change the symmetry of a parabola.
