Answer:

-657

Step-by-step explanation:

a= -1\\b= 4\\

Substituting the value of a and b

3a^{2}-4ab-26^{2}  \\3(-1)^{2} -4(-1)(4)-676\\3-4(-4)-676\\3+16-676\\19-676\\-657

The value of    3a²-4ab-26²  is -657

How many solutions does this system of equations have y=2x y=x^2+2
finlep [7]

The resulting equation has a leading degree of 2, hence the system of equation will have 2 solutions

<h3>Quadratic equations</h3>

Quadratic equations are equations that has a leading degree of 2. Given the following system of equations

y=2x

y=x^2+2

Equate to have:

2x = x^2+ 2

Equate to zero

x^2 - 2x +2 = 0

Since the resulting equation has a leading degree of 2, hence the system of equation will have 2 solutions

Answer:

y=1x+8

Step-by-step explanation:

  1. The best way to remember the formula is y=mx+b aka (your mom's ex bf)
  2. Just by looking at the slope you can automatically tell it's moving by one so in your formula, 'm' is the slope.
  3. Add 1x to replace 'm' or you can leave x alone because x is already one, your choice.
  4. b is the indication on where your slope started in the y-axis.
  5. In this case, by looking at the y-axis on the graph, the slope starts at 8 so that will be your b.
  6. Therefore, your answer is y=1x+8

Write the equation whose roots are 6 and 1, and whose leading coefficient is 4.
Black_prince [1.1K]

Answer:

4(x-6)(x-1) = 0

Standard form: 4x^2-28x+24=0

Step-by-step explanation:

First, let's write an equation where the roots are 6 and 1.

To do that, we can use the intercept form <em>a(x-p)(x-q) = 0</em>, where <em>a</em> is the leading coefficient, and <em>p </em>and <em>q</em> are the roots.

We can therefore plug what we know into this equation:

4(x-6)(x-1) = 0
