Answer:

5\sqrt[\\]{3} \\ or about 8.66

Step-by-step explanation:

To find the distance of any line, you have to use distance formula.

\sqrt{(y-y_{1} )^{2} + (x-x_{1} )^{2}

So, we insert our points:

\sqrt{(5-9 )^{2} + (-3-4 )^{2}

Then you solve, and should end up with \sqrt{75}. Either you can simplify it for an exact number, or you can round. It depends on what the directions ask for.

Solve the following system of equations. If there is no solution, write DNE in each coordinate of the
Rainbow [258]

Answer:

1) solution is y = -7

2.) DNE

3.) Solution is y = -2

Step-by-step explanation:

1.) 2+3 = y + 12

Add the LHS and make y the subject of formula

5 = y + 12

Y = 5 - 12

Y = - 7

The solution of the equation is - 7

2.) 2 + 13 = 1 +8

Since there is no unknown variable and the sum of the numbers in the left hand side ( LHS ) is not equal to the sum of the numbers in the right hand side ( RHS ), it will be concluded that there is no solution in the equation.

3.) y - 7 = 2 - 11

Sum the RHS and make y the subject of formula

Y - 7 = -9

Y = -9 + 7

Y = -2

The solution of the equation is -2

How can you use bar graphs to compare quantities in real life situations
devlian [24]
You can use bar graphs to compare quantities in real life situations by comparing different amounts, ex. you might use them for comparing different prices at a coffee shops around the world or different types of dogs you see at a park on a sunny day. You can really use bar graphs for comparing anything.

Gavin bought snacks for his team's practice. He bought a bag of apples for $2.50 and a 18-pack of juice bottles. The total cost
boyakko [2]

Answer: 87 c

Step-by-step explanation:

To evaluate the cost per juice box, we must first factor out the bag of apples from the equation. So we will disregard the price of the apples from the total price and also disregard the existence of the apples altogether.

Our new subtotal is $15.66 for eighteen juiceboxes. To find the cost for one juicebox, we divide the price & the # of juiceboxes by 18.

15.66÷18=0.87, therefore each juicebox is 87 cents.
