Y - y1 = m (x + x1)

Solve for m by subtracting the y's and dividing them by the difference of the 2 x's.

-32 - 1 = -33
-8 - 3 = -11

Divide the two to get 3.

Use the first point (as instructed) and plug it into the equation.

y - (-32) = 3 (x - (-8))

y + [32] = [3] (x + [5])

The brackets are the fill in the blanks.

The general equation for depreciation is given by y=a(1-r)^t where y=current value.
Jlenok [28]

With the help of the given equation, we know that the automobile is worth $12528.15 after four years.

<h3>What are equations?</h3>
  • A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.
  • a formula that expresses the connection between two expressions on each side of a sign.
  • Typically, it has a single variable and an equal sign.
  • Like this: 2x - 4 Equals 2.
  • In the above example, the variable x exists.

So, the equation of depreciation: y = A(1 - r)∧t

The current value is y.

A is the initial cost.

r is the depreciation rate.

t is the time in years, and

In four years, we must ascertain the present value.

Now,

y = $24000(1 - 0.15)⁴

y = 24000(0.85)⁴

y = 24000 × 0.52200625

y = 12528.15

Therefore, with the help of the given equation, we know that the automobile is worth $12528.15 after four years.

Keisha wants to read for 90 minutes.so far , she has read 30% of her goal. how much longer does she need to reach her goal?
S_A_V [24]
30% of 90            <em>whenever it says "of" put in a multiplication sign </em>
30% x 90             <em> take out the % sign (percent means divided by 100)</em>
30/100 =3/10               <em>simplify,then multiply by 90</em>
3/10 x 90 = 270/10         <em> simplify</em>
270 = 27     
90 - 27 = 63            <em>subtract 27 because it is the amount read so far from the total</em>
Keisha has to read 63 more minutes to reach her goal.

Solve: negative 1 over 2 x + 1 = −x + 8 <br><br> 7<br><br> 1 over 2<br><br> 14<br><br> 18
Nat2105 [25]

The question is an illustration of a linear equation

The solution to the equation -\frac 12x + 1 = -x+8 is x =14

<h3>What are linear equations?</h3>

These are equations that have constant rates or slopes

The equation is given as:

-\frac 12x + 1 = -x+8

Collect like terms in the above equation

-\frac 12x + x=8 - 1

Evaluate the like terms

\frac 12x=7

Multiply both sides of the equation by 2

x =14

Hence, the value of x is 14
