Which ordered pair is the best estimate for the solution of the system of equations? y=32x+6 y=14x−2
Marysya12 [62]

since y = both rewrite as

32x+6 = 14x-2 and solve for x

32x +6 = 14x-2

add 2 to both sides:

32x +8 = 14x

subtract 32x from both sides:

8 = -18x

divide both sides by -18

x = 8/-18 which reduces to -4/9

now use that for x and solve for Y

32(-4/9) +6 = -74/9

ordered pair:

(-4/9, -74/9)

How many liters fit in a cube that is 30 centimeters on a side
astra-53 [7]

Answer:

27\ liters

Step-by-step explanation:

step 1

Find the volume of the cube

The volume of a cube is

V=b^{3}

where

b is the length side of the cube

we have

b=30\ cm

substitute

V=(30)^{3}

V=27,000\ cm^{3}

step 2

Convert cm^3 to liters

Remember that

1\ liter=1,000\ cm^3

27,000\ cm^{3}=27,000/1,000=27\ liters

Solution to (x-2) (x+10) = 13
Grace [21]

Answer:

-11,3

Step-by-step explanation: using foil (x-2)(X+10)=x^2+8x-20

x^2+8x-20-13=13-13 X^2+8x-33=0 factoring you get (x+11)(x-3)=0 so x+11=0

x-3=0

x=-11,3
