Answer:

A) At x = 4 and y = 2

Step-by-step explanation:

When you have something like (4,2), as shown above, the first number in parenthesis is x while the second number is y.

So here, the 4 would be x and the y would be 2

lions [1.4K]

Answer:

The population proportion of households that own at least one snow blower is 0.104.

Step-by-step explanation:

In order to find the population proportion of households that own at least one snow blower, you have to divide the number of people that said they owned at least one snow blower by the number of households surveyed:

26/250=0.104

According to this, the answer is that a point estimate for p, the population proportion of households that own at least one snow blower is 0.104.

Consider the equation ay'' + by' + cy = d, where a, b, c, and d are constants. (a) find all equilibrium, or constant, solutions

Orlov [11]

Rewrite equation so that it is homogeneous .
$ay'' +by' + cy = 0$

Solve characteristic equation:
$ar^2 +br + c = 0 \\ \\ r = \frac{(-b) \pm \sqrt{b^2 -4ac}}{2a}$

The solutions to the homogeneous equation are:
$y = k_1 e^{r_1 t} + k_2 e^{r_2 t}$

Finally you need the constant term in "cy" to equal 'd' to satisfy the particular solution.
$y= k_1 e^{r_1 t} + k_2 e^{r_2 t} + \frac{d}{c}$

How do i Evaluate this expression?

timofeeve [1]

$\text{Hey there!}$

$\bf{9.83+8.2(7.01)}$

$\text{You could solved this equation by doing PEMDAS}$

$\text{PEMDAS simply means}\downarrow$

$\text{Parentheses }$

$\text{Exponents}$

$\text{Multiplication}$

$\text{Division}$

$\text{Addition}$

$\text{Subtraction}$

$\text{In your equation you have \bf{MULTIPLICATION \& ADDITION}}$

$\text{Now, that we have every information we need.. lets solve the problem}$

$\text{We have to do \underline{MULITPLICATION} first then \underline{ADDITION} last}$

$\text{9.83 + 8.2(7.01)}$

$\text{8.2(7.01)=57.482}$

$\text{9.83 + 57.482 = 67.312}$

$\boxed{\boxed{\text{Thus your answer is most likely: \bf{67.312}}}}\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$

Answer:

Second choice:

$x=2t$

$y=4t^2+4t-3$

Fifth choice:

$x=t+1$

$y=t^2+4t$

Step-by-step explanation:

Let's look at choice 1.

$x=t+1$

$y=t^2+2t$

I'm going to subtract 1 on both sides for the first equation giving me $x-1=t$ . I will replace the $t$ in the second equation with this substitution from equation 1.
