How many solutions does the system below have?<br> y=1/2x+1<br> 2y - x = 2

kvasek [131]

Answer:

infinitely many

Step-by-step explanation:

Rewrite these equations as

y = (1/2)x + 1

2y = x + 2

and then solve the second for y: y = (1/2)x + 1. Note that these end results are identical. The two lines coincide; that is, one lies right on top of the other. Thus, there are infinitely many solutions.

Which equation is equivalent to<br><br> f(x) = 16x4 – 81 = 0?

Vesna [10]

Answer:

The equivalent expression is:

$16x^4-81=(4x^2-9)(4x^2+9)$

Step-by-step explanation:

We have been given the equation:

$f(x)=16x^4-81=0$

Equivalent expression can be computed by solving the expression ai its maximum.

We can factorize the given equation:

By using $a^2-b^2=(a+b)(a-b)$

Here, $a=4x^2,b=9$

Hence, we get the equation below:

$16x^4-81=(4x^2-9)(4x^2+9)$

Therefore, the equivalent expression is:

$16x^4-81=(4x^2-9)(4x^2+9)$

For this graph mark the statements that are true

Nitella [24]

For the graph in the figure

we know that

the function is a quadratic equation ( vertical parabola) open up

The vertex is a minimum

the vertex is the point $(1,0)$

The domain x of the function is all real numbers-------> (-∞,∞)

The range is the interval--------> [0,∞)

$f(x)\geq 0$

therefore

Statements

A) The range is the set of all real numbers

Is false

B) The domain is the set of all real numbers

Is true

C) The domain is the set of all real numbers greater than or equal to zero

Is false

D) The range is the set of all real numbers greater than or equal to zero

Is true
