Answer:

8x -24 = 9y

Step-by-step explanation:

We assume your equation is ...

2/3x -2 = 3/4y

Fractions can be eliminated by multiplying the equation by the least common denominator of the fractions.

LCM(3, 4) = 12

Multiplying the equation by 12 gives you ...

12(2/3x -2) = 12(3/4y)

8x -24 = 9y

If R1 and R2 are the roots of x^2+4x-5=0

professor190 [17]

Factor to find the roots.
(x+5)(x-1)=0

Proof:
5-1=4
5*-1=-5

Then apply the Zero Product Property.
(x+5)=0
x=-5

(x-1)=0
x=1

Roots: x=-5, x=1

-4/5x+1=13<br><br> Solve for X?

nekit [7.7K]

Answer:

x=-15 (the * is the multiplication)

Step-by-step explanation:

-4/5x+1=13

-4/5x+1−1=13−1

-4/5x=12

(5/-4) * (-4/5x)= (5/-4)* (12)

x=-15

Manny created a scatter plot and drew a line of best fit, as shown.

AVprozaik [17]

Answer:

y = 2x + 7

Step-by-step explanation:

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Slope-Intercept Form: y = mx + b

We are only focusing on the line of best fit.

Step 1: Find 2 coordinates

(0, 7) y-intercept

(2, 11) random

Step 2: Find slope <em>m</em>

m = (11 - 7)/(2 - 0)

m = 4/2

m = 2

y = 2x + b

Step 3: Rewrite linear equation

y = 2x + 7
