Answer:

y = (3/2)x + 2

Step-by-step explanation:

The equation of a straight line is given by:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept (value of y when x is 0).

From the graph, we can see that the y intercept is 2 units. Also, the line passes through point (2, 5) and (-2, -1). Therefore the slope of the line is:

$slope(m)=\frac{y_2-y_1}{x_2-x_1}=\frac{-1-5}{-2-2}=\frac{3}{2}$

Using the equation a straight line:

y = mx + b; substituting gives:

y = (3/2)x + 2

What does paper folding have to do with exponents?

Marizza181 [45]

Answer:

See below

Step-by-step explanation:

If you take a whole sheet of paper and fold it in half, for instance, you will have 2 rectangles. If you fold it in half again, you will get 4 rectangles, and so on. Each time you fold by one-half, you keep doubling the amount of rectangles.

Please help!!!!!<br>Solve the equation 5(2y - 1) - 2(3y)= 1<br>

-Dominant- [34]

Answer:

y = 3/2

Step-by-step explanation:

5(2y - 1) - 2(3y) = 1

First we use distributive property:

10y - 5 - 6y = 1

because 5 × 2y = 10y

and -2 × 3y = -6y

Now we combine the like terms:

4y -5 = 1

because 10y - 6y = 4y

Now we have to send the -5 to the other side. (when we send it to the other side it becomes positive because right now it is negative)

4y = 1 + 5

Again we combine the like terms:

4y = 6

(because 5 + 1 = 6)

Now we have to send the 4 to the other side because we need to get the y value. (when we send it to the other sidr it will be divided)

y = 6/4

and we simplify:

y = 3/2

And we cannot simplify or do anything else. So that is the answer.

Hope that helped!

Starting in the year 1800, the population of the United States was recorded until the year 2000. The data is summarized below wi

krok68 [10]

Answer:

$a = 73.84$ , $b = -23.64$ , $c = 83.97$ , $d = 21.73$

Step-by-step explanation:

1880:

The predicted value is:

$f(80) = 1.363\cdot (80) - 35.2$

$f(80) = 73.84$

The residual value is:

$\Delta f = 50.2 - 73.84$

$\Delta f = -23.64$

1920:

The predicted value is:

$f(120) = 7.8 \cdot 1.02^{120}$

$f(120) = 83.97$

The residual value is:

$\Delta f = 105.7 - 83.97$

$\Delta f = 21.73$

Which of the following expressions are equivalent to 2/x^6-y^6? Choose all that apply.

enot [183]

Answer:

A and C

Step-by-step explanation:

Equivalent expressions are expression which when simplified to lowest terms are equal.

Simplify each answer choice to find the expression which simplifies to $\frac{2}{x^6-y^6}$ .

A. Multiply the exponents 3*2 = 6. This is equal.

B. Multiply numerators and denominators. Here the numerator will be 1*1 = 1. It does not equal 2 in the numerator.

C. Here the numerator does equal 2. The denominator multiplies to $(x^3 - y^3)(x^3+y^3)\\x^6 -x^3y^3 + x^3y^3 -y^6\\x^6 - y^6$

This is equal.

D. The denominator will have three terms here when simplified. This will not be equal.
