Answer:

(2,14)

Step-by-step explanation:

so i solved this with substitution but there are other methods to solve this!

equation 1 : y = -x + 16
equation 2 : y = x + 12

solve for y in equation 1 !!
y = -x + 16
(add x on both sides)
y + x = 16
(subtract y on both sides)
x = -y + 16

equation 1 now equals : x = -y + 16

substitute equation 1 into equation 2 :)

y = (-y + 16) + 12
(add 16 + 12)
y = -y + 28
(add y on both sides)

2y = 28
(divide 2 on both sides)
y = 14

now to solve for x you can insert y !
you can use equation 1 or equation 2 to solve for x.

i'm using equation 2 :
y = x + 12
(14) = x + 12
(subtract 12 on both sides)
x = 2

therefore, the answer is (2, 14).

hope this helps :p

What is the solution to -3/4 x + 2 ≤ -7 ?

Dvinal [7]

Answer:

x ≥ 12

Step-by-step explanation:

Step 1: subtract 2 from both sides

Now you have; -3/4 x ≤ -9

Step 2: divide both sides by -3/4

Now you have x ≥ 12

(when dividing an inequality by a negative you have to flip the sign)

Therefore the answer is x ≥ 12

Solve the problem:

stepan [7]

volume of the box is 675 cubic inches

A machine produces open boxes using square sheets of plastic.

It is a square sheet so length and width are same

Lets assume length as x so width is also x

The machine cuts equal-sized squares measuring 3 inches on a side from each corner of the sheet.

After turning up the sides the height of the box becomes 3 inches

We know the volume of a box formula

Volume = Length * width * height

We know length is x , width is x and height = 3

So V = x * x * 3

Given volume = 675 cubic inches

$675 = x * x * 3$

$675 = x^2* 3$

Divide by 3 on both sides

$225 = x^2$

Now we take square root on both sides

x = 15

the length of one side of the open box is 15 inches.

Use the compound interest formulas upper a equals upper p left parenthesis 1 plus startfraction r over n endfraction right paren

jekas [21]

Answer:

a. A=$11,428.25

b. A=$11,436.74

c. A=$11,442.48

d. A=$14,445.37

Step-by-step explanation:

The compound interest formula is:

$A=P(1+\frac{r}{n})^{nt}$

Where:

P=10,000

t= 3 years

r=0.045

n = periods compounded in a year.

a. compounded semiannually:

$A=10,000(1+\frac{0.045}{2})^{2*3}\\A=11,428.25$

b. compounded quarterly:

$A=10,000(1+\frac{0.045}{4})^{4*3}\\A=11,436.74$

c. compounded monthly:

$A=10,000(1+\frac{0.045}{12})^{12*3}\\A=11,442.48$

d. compounded continuously:

The continously compounded interest equation is:

$A=10,000e^{(0.045*3)}\\A=14,445.37$
