Answer:

1 1/2x

Step-by-step explanation:

90 minutes is 1 and 1/2 hours so I put that with the x on the end so when you get the number times it by that

Question 5 Multiple Choice Worth 1 points) (04.05 MC) Determine if the ordered pair (-1 , -5) is a solution to the inequality y≤

Zielflug [23.3K]

Answer:

(-1, -5) satisfies the inequality and will be the solution to the inequality.

From the attached figure, it is clear that (-1, -5) is below the line.

Therefore, the correct option is:

''Yes, because 1-1, 5) is on the line''.

Step-by-step explanation:

Given the inequality

$y\le -\frac{3}{4}x-1$

substituting (-1, -5) to check whether it satisfies the inequality or not

$-5\le \:-\frac{3}{4}\left(-1\right)-1$

$-5\:\le \:\frac{3}{4}-1$

$-5\:\le -\frac{1}{4}$

TRUE

Thus, (-1, -5) satisfies the inequality and will be the solution to the inequality.

From the attached figure, it is clear that (-1, -5) is below the line.

Therefore, the correct option is:

''Yes, because 1-1, 5) is on the line''.

Naily [24]

Answer:

C. P = 1.6w + 8.5

Step-by-step explanation:

In y= mx + b,

8.5 is (b) because it is the starting weight. The baby's weight gain would be represented by (m), because it changes every week.

∠TUV and ∠MNO are supplementary. m∠TUV = 75° and m∠MNO = (5x)°. Find the value of x and the measure of ∠MNO. Show your work.

DedPeter [7]

Answer:Angle MNO=105°

x=21°

Step-by-step explanation:Angle MNO+Angle TUV=180°

75+5x=180°

5x=105°

x=21°

Angle MNO=105°

How is this solved? graph and explanation would be helpful

Nastasia [14]

As a rule, you plot the lines as though the equations had an equal sign. Because both are strict inequalities (no "or equal to"), the lines are dashed, indicating the (x, y) values on the line are NOT part of the solution.

The solution space will be above the first line (y > ...) and below the second line (y < ...). As a rule, you indicate the solution space by shading the portion of hte plane that satisfies the inequality.* The solution is the portion of the plane that is in both solution regions (that is, doubly-shaded).

_____
* Sometimes, it may actually work better to shade the portion of the plane that does NOT satisfy the inequality. That way, the remaining unshaded area is the solution space. If you do it that way, make sure the graph is clearly marked indicating that is the case. The usual expectation is that the shaded area is the solution, so you don't want to get your answer marked wrong or misinterpreted.
