A plant is already 14 centimeters tall, and it will grow one centimeter every month.

Semenov [28]

Answer:

H=M+14

Step-by-step explanation:

When writing an equation you should always look at the problem and try to figure out what it is asking you to solve for. In this case you would be solving for the plants height (H). That will be one side of our equation.

<u>H=???</u>

Now we must think about how we would solve for the height. The plant grows 1 centimeter each month so we will put M on the other side. But since it is we will add 14 to that.

<u>H=M+14</u>

The monthly cost (in dollars) of water use is a linear function of the amount of water used (in hundreds of cubic feet, HCF). Th

ziro4ka [17]

Answer:

67.49

Step-by-step explanation:

Let the number of HCF be x.

Let the cost be y.

You are given 2 points of a line: (15, 32.84) and (43, 79.04).

Now we find the equation of the line that passes through those points.

y - y1 = m(x - x1)

y - 32.84 = [(79.04 - 32.84)/(43 - 15)](x - 15)

y - 32.84 = (46.2/28)(x - 15)

y - 32.84 = 1.65(x - 15)

y = 1.65x - 24.75 + 32.84

y = 1.65x + 8.09

Now we let x = 36 and solve for y.

y = 1.65(36) + 8.09

y = 67.49

Maria is buying a car for $18,510. She will finance $13,000 of it with a 3-year loan at 2.8% APR. What will her monthly auto pay

Eva8 [605]

<u>Answer-</u>

<em>Maria's monthly payment will be </em><em>$376.91</em><em> </em>

<u>Solution-</u>

Maria is buying a car worth of $18,510, but she will finance only $13,000 of it with a 3-year loan at 2.8% APR.

We know that,

$\text{PV of annuity}=P[\dfrac{1-(1+r)^{-n}}{r}]$

Here,

$\text{PV of annuity=13000},\\\\\text{P=??},\\\\\text{r = 2.8\%\ annually}=\frac{2.8}{12}\text{\%\ monthly}\\\\\text{n=3 years=36 months}$

Putting the values,

$\Rightarrow 13000=P[\dfrac{1-(1+\frac{2.8}{1200})^{-36}}{\frac{2.8}{1200}}]$

$\Rightarrow 13000=P\times 34.4909$

$\Rightarrow P=\dfrac{13000}{34.4909}$

$\Rightarrow P=376.91$

Therefore, her monthly payment will be $376.91

Identify the values a, b, and c is the first step in using the quadratic formula to find the solution(s) to a quadratic equation

zlopas [31]

The values are a = 7, b = -9, c = -18.

<u>Step-by-step explanation:</u>

The given quadratic equation is $7x^{2} - 9x = 18$

The general form of the quadratic equation is $ax^{2} + bx + c = 0$

where,

a is the coefficient of x².
b is the coefficient of x.
c is the constant term.

Now, you have to modify the given quadratic equation similar to the general form of quadratic equation.

So, bring the constant term 18 to the left side of the equation for equating it to zero.

⇒ $7x^{2} - 9x - 18 = 0$

Compare the above equation with general form $ax^{2} + bx + c = 0$

⇒ a = 7

⇒ b = -9

⇒ c = -18

Therefore, the values of a, b, and c are 7, -9 and -18.
