Solve the equation by factoring.<br> 3z2 + 3z – 6 = 0<br> z = 3 or z = 2
lana66690 [7]

Answer:

<u>3</u><u>z</u><u>^2 + 3z - 6 </u>=0

3

3 (z^2 + z -2) = 0

3(z+2)(z - 1) = 0

z + 2-2 = 0 - 2

z = -2

z - 1 + 1 = 0 + 1

z = 1

Step-by-step explanation:

  1. factor out the GCF (3) and divide everything by it, and then set it equal to zero.
  2. since you have a degree of 2, factor it into two binomials that start with the square root of the first term and end with the square root of the second term.
  3. 3=0 is extraneous solution so we leave it, then we set each binomial equal to zero to solve for z.

note: your solutions is based on the degree or the exponent of the polynomial or the function.

Adjust the equation so the line passes through the points. Y=x+1
lapo4ka [179]

Answer:

Slope=  

2.000

2.000

​  

=1.000

x−intercept=  

−1

1

​  

=−1.00000

y−intercept=  

1

1

​  

=1.00000

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    y-(x+1)=0

Equation of a Straight Line

1.1     Solve   y-x-1  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  y-x-1  = 0 and calculate its properties

Graph of a Straight Line :

 

 

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 1/1 so this line "cuts" the y axis at y= 1.00000

 y-intercept = 1/1  =  1.00000  

Calculate the X-Intercept :

When y = 0 the value of x is 1/-1 Our line therefore "cuts" the x axis at x=-1.00000

 x-intercept = 1/-1  = -1.00000  

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.000 and for x=2.000, the value of y is 3.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 3.000 - 1.000 = 2.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  2.000/2.000 =  1.000  

Geometric figure: Straight Line

1.  Slope = 2.000/2.000 = 1.000

2. x-intercept = 1/-1 = -1.00000

3.  y-intercept = 1/1 = 1.00000

Find the solution of y = 2x + 5 for x = 1.
Sholpan [36]

Answer:

(1, 7)

Step-by-step explanation:

Substitute x = 1 into the equation for the corresponding value of y

y = 2x + 5 = (2 × 1) + 5 = 2 + 5 = 7

Solution is (1, 7)
