Answer:

y = -2x+12

Step-by-step explanation:

slope intercept form is y=mx+b, where m is the slope, and b is the y intercept.

let's set the equation equal to y.

4x + 2y = 24 becomes y = 12-2x (see work below)

2y = 24 - 4x

y = 12 - 2x

From this new equation, we can determine that the slope is -2, and the y-intercept is 12.

For a track meet, Tara ran the 1,600 m event at constant speed in 5 minutes and 20 seconds. What was her speed?

9966 [12]

Answer:

300 m/min

Step-by-step explanation:

Using the general formula of d = rt, where d = distance, r = rate and t = time, we can solve for the missing variable (r, or speed). Given Tara's distance of 1600 m and her total time of 5 minutes and 20 seconds, first convert her time into just minutes:

5 $\frac{20}{60}=\frac{1}{3}$

5 $\frac{1}{3}=\frac{16}{3}$

1600 = r(16/3)

Multiply both sides by reciprocal of 16/3: 3/16(1600) = r(16/3)(3/16)

Solve for 'r': 300 meters per minute

Answer:

The graph in the attached figure

The point (-1,4) represent a solution

Step-by-step explanation:

we have

$x> -2$ ----> inequality A

$y\leq 2x+7$ ----> inequality B

using a graphing tool

The solution is the shaded area

see the attached figure

Remember that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area of the solution of the system of inequalities

The point (-1,4) represent a solution
