Consider this linear function y=1/2x+1 plot all ordered pairs for the values in the domain D:{-8,-4,0,2,6}

devlian [24]

Answer:

Following are the calculated points to the given question:

Step-by-step explanation:

$When\ x=-8\\\\y=\frac{1}{2}(-8)+1=-3\\\\$

so,

$Point \ A(-8,-3)$

$When\ x=-4\\\\y=\frac{1}{2}(-4)+1=-1\\\\$

so,

$Point \ B(-4,-1)$

$When\ x=0\\\\y=\frac{1}{2}(0)+1=1\\\\$

so,

$Point \ C(0,1)$

$When\ x=2\\\\y=\frac{1}{2}(2)+1=2\\\\$

so,

$Point \ D(2,2)$

$When\ x=6\\\\y=\frac{1}{2}(6)+1=4\\\\$

so,

$Point \ E(6,4)$

Eliminate the parameter. x = t2 + 3, y = t2 - 2

abruzzese [7]

Answer: y = x - 5

Step-by-step explanation:

"Eliminate the parameter" means we want to eliminate the extra variable and rewrite it ias one equation that only contains x, y, and possibly a constant.

The extra variable in the equations is "t". Manipulate one of the equations to solve for t². Then substitute t² = _____ it into the other equation.

x = t² + 3 → x - 3 = t²

y = t² - 2

y = (x - 3) - 2

y = x - 5

What are the solutions to 0=x^2-x+1?

kumpel [21]

Answer: No solutions

Step-by-step explanation:

There are no solutions to 0 = x² - x + 1.

[Method One]

We can solve this by rewriting the equation, but it is quicker to graph it when there are no solutions. See attached.

[Method Two]

I said we can solve this by solving an equation, here it is. We will use the quadratic formula since the equation given is already in the proper form.

$\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$
