Answer:

y= 3x

Step-by-step explanation:

The slope is just read. It is 3. It is the value of m in the general equation.

y = mx + b

y = 3x + b

To find b, use (-1,-3)

x = -1

y = -3 Substitute into the general equation

-3 = 3(-1) + b Simplify the right side

-3 = -3 + b Subtract -3 from both sides

b = 0

Answer: y = 3x

Answer:

Step 1 is wrong

Step-by-step explanation:

$\frac{1}{4} r+ 2 = 10$

$\frac{r}{4} + 2 = 10$

$\frac{r}{4} = 10 - 2$

$\frac{r}{4} = 8$

$r = 8 \times 2$

$r = 32$

What percent of 33 is 96

Nataly_w [17]

<span>96/x=100/33
(96/x)*x=(100/33)*x - we multiply both sides of the equation by x
96=3.0303030303*x - we divide both sides of the equation by (3.0303030303) to get x
96/3.0303030303=x
31.68=x
x=31.68

now we have:
33% of 96=31.68

2. You are given the hyperbolic relation modeled by xy = -2. Do the following: a) Rewrite the relation such that the dependent v

N76 [4]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

The given equation is :

$xy = - 2$

1. The relationship such that dependent variable (y) is isolated is :

$y = \dfrac{ - 2}{x}$

2. The table accompanying this equation :

x = -4 and y = 0.5

x = -1 and y = 2

x = - 0.5 and y = 4

x = 0 and y = undefined

x = 0.5 and y = -4

x = 1 and y = -2

x = 4 and y = -0.5

3. graph of the given equation is in attachment ~
