6 0

12x²-9x = 0
3x(4x-3)=0
4x-3=0
4x=3
x=3/4
so either x = 0 or x = 3/4

Write the equation of the line that passes through the points (-7, 7) and (-6, -5).

defon

Answer:

y = -12x - 77

Step-by-step explanation:

The standard form of the equation is expressed as y = mx+b

m is the slope

Given the coordinate (-7, 7) and (-6, -5).

m = -5-7/-6+7

m = -12/1

m = -12

Get the intercept b

Substitute m= -12 and (-7 7) into y = mx+b

7 = -12(-7) + b

7 = 84 + b

b = 7 - 84

b = -77

Get the required equation

y = mx+b

y = -12x +(-77)

y = -12x - 77

This gives the required equation

Select the two points that the line would go through. Practice on a piece of paper in front of you.

Mama L [17]

Answer:

(1,-3), (2,-2)

Step-by-step explanation:

The graph passes through (3, -1) and (0, -4)

The slope is:

(-4 - (-1))/-3 = -3/-3 = 1

The y-intercept is given: -4

The line is:

y = x - 4

See the graph

The points plotted as well and those on the line are:

(1,-3)
(2,-2)

Arbara signed up for dance lessons at Dance Unlimited. She was charged $55 per month for lessons and a one-time recital fee of $

kramer

Given:

Per month fee = $55

One-time recital fee = $165

The equation represents the $495 total cost that Barbara paid to Dance Unlimited.

$495=165+55m$

To find:

We need to find the number of month Barbara receive dance lessons from Dance Unlimited.

Solution:

We have,

$495=165+55m$

Here, m is number of months. We need to isolate m.

Subtract 165 from both sides.

$495-165=55m$

$330=55m$

Divide both sides by 55.

$\dfrac{330}{55}=m$

$6=m$

The value of m is 6. So, the required number of month Barbara receive dance lessons from Dance Unlimited is 6.
