<h2>Answer:</h2>

The system of linear equation that is graphed is:

Option: A

A. y > -1 and y ≤ -x

<h2>Step-by-step explanation:</h2>

By looking at the graph we observe that the first inequality:

Is a strict inequality (since the graph is a dotted line which passes through (0,-1) and is a horizontal line parallel to the x-axis )

Also, the shaded region is above the line i.e. towards the origin.

This means that the line passes the zero point test.

Hence, the inequality which satisfies this condition is:

y > -1

Also, the graph of the second inequality:

Is a solid line (i.e. the inequality is not strict) and the line satisfies the relation y= -x and the shaded region lie below the line i.e. the inequality is given by:

y ≤ -x

You can put this solution on YOUR website!

If 37% get less than 8 hours of sleep, 100%-37%=63%

63% get 8 hours or more per night:

(0.63)(2200)=1386

ANSWER: You would expect 1386 to get 8 or more hours of sleep per night.

This is an equation! Solutions: x=1.

Graphical form: Equation 3%2Ax-x%2B2=4 was fully solved.

Text form: 3*x-x+2=4 simplifies to 0=0

Cartoon (animation) form: simplify_cartoon%28+3%2Ax-x%2B2=4+%29

For tutors: simplify_cartoon( 3*x-x+2=4 )

Delaney would like to make a 10 lb nut mixture that is 60% peanuts and 40% almonds. She has several pounds of peanuts and severa

scoundrel [369]

Answer:

a) p + m = 10 and $\frac{p + 0.2m}{0.8m} = \frac{60}{40}$

b) The mixing amount is 5 lb peanut and 5 lb mixture.

Step-by-step explanation:

Given that p pounds of peanuts and m pounds of the 80% almond and 20% peanut mixture are used to make 10 pounds of 60% peanuts and 40% of almonds mixture.

Now, we can write that p + m = 10 ........ (1)

Now, m pounds of 80% almond and 20% peanut mixture contain 0.2m pounds of peanuts and 0.8m pounds of almonds.

Now, from the condition given it can be written that

$\frac{p + 0.2m}{0.8m} = \frac{60}{40}$ .......... (2)

⇒ $\frac{p + 0.2m}{0.8m} = \frac{3}{2}$

⇒ 2p + 0.4m = 2.4m

⇒ 2p = 2m

⇒ p = m

Now from equation (1) we get p = m = 5 pounds.

a) Therefore, equations (1) and (2) are the system of equations that models the situation.

b) The mixing amount is 5 lb peanut and 5 lb mixture. (Answer)

What is the solution in the equality -3x-42>3?

Umnica [9.8K]

-3x-42>3
-3x>45
x<-15

I chose x<-15 because through the process of elimination, if it was an equality, x=-15. Since it is an inequality, when dividing both sides by a negative, the sign switches.
