The amount y (in dollars) that you earn by working x hours is represented by the equation y = 9x. A) What is the slope? B) What

marissa [1.9K]

Answer:

360 dollars

Step-by-step explanation:

Equation;

y = 9x

A) What is the slope?

The slope in an equation is the coefficient of the x variable. In this question, the slope is 9.

B) What does the slope mean? Interpret!

The slope shows the relationship between the x and y values.

This means that for every single unit change of x, y changes by 9 times.

C) How much money would you make if you worked 40 hours?

x = working hours

y = Amount

y = 9 (40) = 360 dollars

A positive real number is 1 more than another. When -2 times the smaller is added to the square of the larger, the result is 33.

Naya [18.7K]

Answer:

The smaller number is 4√2 and the larger number is (4√2 + 1).

Step-by-step explanation:

Let the two numbers be <em>x </em>and <em>y</em>, where <em>y</em> is the larger of the two numbers.

Since <em>y</em> is the larger number, it is one more than the smaller number. So:

$y=x+1$

When negative two times the smaller is added to the square of the larger, the result is 33. In other words:

$-2x+y^2=33$

Substitute:

$-2x+(x+1)^2=33$

Solve for <em>x</em>. Square:

$-2x+(x^2+2x+1)=33$

Simplify:

$x^2+1=33$

Subtract one from both sides:

$x^2=32$

And take the square root of both sides:

$x=\pm\sqrt{32}=\pm 4\sqrt{2}$

Since <em>y</em> is positive, we can ignore the negative case. So, the smaller number is:

$x=4\sqrt{2}\approx5.66$

And the larger number is:

$y = 4\sqrt{2} + 1 \approx6.66$

katen-ka-za [31]

Answer/Step-by-step explanation:

Volume = L*W*H

L = 10.4

W = 5

H = 8

10.4* 5 = 52

L*W = 52

52* 8 = 416

L*W*H = 416

Therefore,

B= [2 8 .6 3 ] A= 3 0 2 -1]<br> what is BA ?

Genrish500 [490]

The dot product of two vectors is defined as the sum of the multiplication of each of its components.
We have then:
B = [2 8 .6 3]
A = [3 0 2 -1]
Making the product point:
BA = [2 8 .6 3] [3 0 2 -1]
BA = (2 * 3) + (8 * 0) + (0.6 * 2) + (3 * (- 1))
BA = 4.2
Answer
BA = 4.2
