Floyd is an aspiring music artist. He has a record contract that pays him a base rate of $200 a month and an additional $12 for

Y_Kistochka [10]

Answer:

$37\ albums$

Step-by-step explanation:

Let

x -----> the number of albums Floyd sold last month

we know that

The number of albums Floyd sold last month multiplied by $12 for each album plus a base rate of $200 must be equal to the total earned.

Last month he earned a total of $644

The linear equation that represent this problem is

$12x+200=644$

Solve for x

subtract 200 both sides

$12x=644-200$

$12x=444$

Divide by 12 both sides

$x=37\ albums$

Which of the following graphs is described by the function below ?

const2013 [10]

Answer:

The point of interception of the graph and x axis are -2.366 and -0.634.

The only graph that satisfy this conditions is Graph A

Step-by-step explanation:

Given the equation;

$y = 2x^2 + 6x + 3\\$

at y = 0

$2x^2 + 6x + 3=0\\$

the roots of the quadratic equation (at y =0) can be calculated using the quadratic formula;

$x = \frac{-b\pm \sqrt{b^2 -4ac}}{2a}$

Using the quadratic equation to solve for the roots;

$x = \frac{-6\pm \sqrt{6^2 -4*2*3}}{2*2}\\x = \frac{-6\pm \sqrt{36 - 24}}{4}\\x = \frac{-6\pm \sqrt{12}}{4}\\so, we have \\x = -2.366\\or\\x = -0.634\\$

Therefore, the point of interception of the graph and x axis are -2.366 and -0.634.

The only graph that satisfy this conditions is Graph A

Answer:

AB is A

BC is B

AC is D

Step-by-step explanation:

To find the length of each side, use the formula for the distance between coordinate pairs.

We can find the distance using the distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

AB

We then substitute (-3,6) as $(x_1,y_1)$ and (2,1) as $(x_2,y_2)$ .

$d=\sqrt{(2--3)^2+(1-6)^2} \\d=\sqrt{(2+3)^2+(-5)^2} \\d=\sqrt{25+25}\\d=\sqrt{50}$

BC

We then substitute (2,1) as $(x_1,y_1)$ and (9,5) as $(x_2,y_2)$ .

$d=\sqrt{(9-2)^2+(5-1)^2} \\d=\sqrt{(-7)^2+(4)^2} \\d=\sqrt{49+16}\\d=\sqrt{65}$

AC

We then substitute (-3,6) as $(x_1,y_1)$ and (9,5) as $(x_2,y_2)$ .

$d=\sqrt{(9--3)^2+(5-6)^2} \\d=\sqrt{(12)^2+(-1)^2} \\d=\sqrt{144+1}\\d=\sqrt{145}$
