Carla is saving money for a trip. She already has some money in her savings account and will add the same amount to her account
Bingel [31]

Answer:

280=8x + 130

Step-by-step explanation:

Im pretty sure this is correct it has been a while since I did this but y is the total amount so y is 280. M is the slope so it would be how often the amount changes so m is 8. x is unknown and what needs to be solved for. b is the y intercept which is just the initial amount of 130.

2. Solve x - 19 <81. Then graph the solution.
mr_godi [17]

Answer:

x<100

Step-by-step explanation:

The given equation is :

x-19<81

Adding 19 to both sides of the equation.

x-19+19<81+19

x<100

It means the solution of the given equation is less than 100. Hence, the attached figure shows the graph for the given equation.

13. The perimeter P (in yards) of a soccer field is represented by the formula P = 24 + 2w,
rjkz [21]

Answer:

w = \frac{1}{2}(P - 24)

w = 153\ yards

Step-by-step explanation:

Given

P = 24 + 2w

Require

Solving (a):

P = 24 + 2w

Subtract 24 from both sides

P-24 = 24-24 + 2w

P-24 = 2w

Divide both sides by 2

\frac{1}{2}(P - 24) = \frac{2w}{2}

\frac{1}{2}(P - 24) = w

w = \frac{1}{2}(P - 24)

Solving (b):

Substitute 330 for P un the expression in (1)

w = \frac{1}{2}(330 - 24)

Evaluate the bracket

w = \frac{1}{2}(306)

w = 153\ yards
