−7x−2y=14 6x+6y=18 Graph the system of equations.

1 answer:

3 0

X= -4
y= 7

you can multiply the top equation by 3, then both y's are cancelled or zeroed out. You add -21 and 6 to get -15x. Than you add 42 and 18 to get 60. So, -15x=60 and from there you do 60/-15 to get x=-4. Plug in what you got for x into any of the two equations to get y, which is 7.

A map using a scale inch of 1 to 5 miles shows a section of land with an area of 3.2 in.² what is the actual area of the section

Karolina [17]

Answer:

The actual area of land is 80 mi² .

Step-by-step explanation:

Given that we have to find the actual area so first we have to square the ratio(scale factor) :

1 in : 5 mi

(1 in)² : (5 mi)²

1 in² : 25 mi²

Next, the actual area will be :

1 in² = 25 mi²

(1 × 3.2) in² = (25 × 3.2) mi²

3.2 in² = 80 mi²
