Solving Quadratic Equations by completing the square<br><br> xz^2 - 3z - 5 =0
Andrei [34K]

Answer:

x=3z+5

/z^2

Step-by-step explanation:

Let's solve for x.

xz^2−3z−5=0

Step 1: Add 5 to both sides.

xz^2−3z−5+5=0+5

xz^2−3z=5

Step 2: Add 3z to both sides.

xz^2−3z+3z=5+3z

xz^2=3z+5

Step 3: Divide both sides by z^2.

xz^2

/z^2

=

3z+5/

z^2

x=

3z+5

/z^2

Answer:

x=3z+5

/z^2

Which values of m and b will create a system of equations with no solution? Select two options.
natima [27]

Using linear function concepts, a system of equations with no solutions is created when:

m = -2, b \neq \frac{3}{2}

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

The intersection of two lines is the solution of a system of equations. If two lines have the <u>same slope and different intercepts</u>, they will never intercept, that is, the system will not have a solution.

The lines are given as follows:

  • y = mx + b.
  • y = -2x + 3/2.

Hence, for a system with no solution, we need that:

m = -2, b \neq \frac{3}{2}

Help please tap the picture above
Wewaii [24]

Answer:

a = 8

r = 15%

When t = 3, y= 4.9

Step-by-step explanation:

8 represents the original amount because that's what you're increasing, so a=8.

To find your percentage, look into the parenthesis to see the decimal. We see that it's 0.15, but that's not a percentage yet, so you have to multiply it by 100. Or, moving your decimal two times to the right. Therefore, r=15%.

Now to find what the function will equal when t=3, simply plug 3 for t. I've always used a calculator for this so I'm not going to write it out (sorry). Your result should be 4.9 (this is already rounded to the nearest tenth for you).
