There is an 80% chance to find a red or purple. The total number of markers is 40 and the combined number of red and purple is 32. Dividing 32 by 40 gives you 4/5, 0.8, or 80%

What is the equation of the following line written in general form? (The y-intercept is 7.)
Viktor [21]

Answer:

<h2>3x - y + 7 = 0</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

Put the given y-intercept b = 7 and the coordinates of the point (-2, 1) to the equation:

1=-2m+7          <em>subtract 7 from both sides</em>

-6=-2m       <em>divide both sides by (-2)</em>

3=m\to m=3

We have the equation:

y=3x+7

Convert it to the general form Ax+By+C=0:

y=3x+7              <em>subtract 3x and 7 from both sides</em>

-3x+y-7=0           <em>change the signs</em>

3x-y+7=0

Solve the following formula for t.<br> A= J(1 + rt)
Lubov Fominskaja [6]

Explic

Pasos para resolver una ecuación linea

A=J(1+rt)

Usa la propiedad distributiva para multiplicar J por 1+rt.

A=J+Jrt

Intercambie los lados para que todos los términos de las variables estén en el lado izquierdo.

J+Jrt=A

Combina todos los términos que contienen J.

(1+rt)J=A

La ecuación está en formato estándar.

(rt+1)J=A

Divide los dos lados por 1+rt.

rt+1(rt+1)J=rt+1A

Al dividir por 1+rt, se deshace la multiplicación por 1+rt.

J=rt+1A
