Without building the graph find the coordinates of the point of intersection of the lines gIven by the equations y=2x+3 and 3x+y

Natali5045456 [20]

Answer:

intersection is (1,5)

Step-by-step explanation:

plug one equations into the other

y=2x+3

3x+y=8

3x+2x+3=8

simplify

5x+3=8

subtract 3

5x=5

x=1

plug x into one equation

y=2+3=5

intersection is (1,5)

HELPPPPPPPPPPPP PLZZZZZZZZZZZZ<br> NO LINKS PLEASE AND THANK YOU .

Let’s choose the first one, and do the proportions.

x/30 = 90/100
Cross multiply and you have
100x = (30)(90)
100x = 2700
x = 27

And the fourth one: multiply by the decimal equivalent of the percent.
90% = 90/100 = 0.9
0.9 x 30 = 27

You chose these because your “online tutor” finds them easiest to explain XD

The table shows the total cost for different numbers of jackets. Number of jackets 2 5 7 Total cost ($) 46. 50 116. 25 162. 75 W

The cost price of 1 jacket is $23.25 and the cost price of 3 jackets is $69.75.

<h3>What is the cost price?</h3>

Cost price is the total amount of money to produce a given product or provide a given service.

Given cost prices for jackets are,

Jackets Cost Price

2 46.5

5 116. 25

7 162. 75

We need to calculate the cost price of 3 jackets. First, we need to find out the cost price of one jacket.

$2 \; \rm Jackets =\$ 46.50$

$1 \;\rm Jacket = \dfrac {\$46.50}{2}$

$1 \;\rm Jacket = \$ 23.25$

Now the cost price of 3 jackets is given as,

$3\;\rm Jackets = \$23.25 \times 3$

$3\;\rm Jackets = \$69.75$

Hence we can conclude that the cost price of 3 jackets is $69.75.
