Answer:

y>2x+1 and x+y < -2 represent the graph line.

Step-by-step explanation:

Given : graph .

To find : Which system of linear inequalities is graphed

Solution : We have given graph with two line both lines are dotted line and shaded down.

Equation of line form  : y = mx + b.

Where, m = slope ,  b= y intercept.

Line x+y < -2 less than sign for shaded down and y intercept -2.

and y>2x+1.

Therefore, y>2x+1 and x+y < -2 represent the graph line.

Both lines are dotted so no equation should include equal to in it.

The shaded area is on the left side .

The correct answer would be y>2x+1 and x+y = -2

The 3rd answer is correct.

Marco is 8 years younger than his brother Paolo. If their product of their ages is 105, how old is Marco? plz help
Nina [5.8K]

Answer:

Marco's age is 7 years old

Step-by-step explanation:

Let

x ----> Marco's age

y ----> Paolo's age

we know that

x=y-8 ----> y=x+8 ----> equation A

xy=105 ----> equation B

substitute equation A in equation B

x(x+8)=105

x^2+8x-105=0

Solve the quadratic equation

The formula to solve a quadratic equation of the form

ax^{2} +bx+c=0

is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

x^2+8x-105=0

so

a=1\\b=8\\c=-105

substitute in the formula

x=\frac{-8(+/-)\sqrt{8^{2}-4(1)(-105)}} {2(1)}

x=\frac{-8(+/-)\sqrt{484}} {2}

x=\frac{-8(+/-)22} {2}

x=\frac{-8(+)22} {2}=7

x=\frac{-8(-)22} {2}=-15

Remember that the solution cannot be a negative number

so

The solution is x=7

therefore

Marco's age is 7 years old

PLEASE HELP! URGENTTTTTT

25% is being taken off the original price, p, of each patio chairs. 

That means the price of each patio chair is the full price, p, minus <span>25% of the original price.
1) To find 25% of the original price, multiply p (original price) by the decimal form of 25%, or 0.25. That means 25% off original price = 0.25p. 
2) Now subtract 0.25p from the original price of the chairs to find the price of each (1) chair. p - 0.25p

Shylah is buying 4 chairs at that discounted price. That means you need to multiply the discounted price, </span> p - 0.25p, by 4. Shylah is paying 4(p-0.25p) total for the 4 chairs, which is answer choice B.

Since you can choose more than one choice, you can simplify 4(p-0.25p) by subtracting what is in the parathesis, then multiplying, following the order of operations:
4(p-0.25p) 
= 4(0.75p)  
= 3p
That is answer choice A. 

--------

Answer: Choices A and B, <span>3p and 4(p−0.25p).</span>
