Given that (-3,7) is on the graph of f(x), find the corresponding point for the function f(x + 5).

Stella [2.4K]

We have that
<span>(-3,7) is on the graph of f(x), find the corresponding point for the function
f(x + 5)

we know that
in the transformation f(x)-------> f(x+5)
the point (x.y) in f(x) becomes a point (x-5,y) in f(x+5)
so
(-3,7)-----------> becomes a point (-3-5,7)------> (-8,7)

the answer is
</span>(-8,7)<span>

</span>

Solve by taking the square root I need help understanding steps this is hard for me.

Shalnov [3]

Answer:

x= $-2 \pm \sqrt{13}$

Step-by-step explanation:

Given: $3x^{2} -12x+27= 0$

This is a quadratic equation.

$3x^{2} -12x+27= 0$

Taking common 3 from the equation given

⇒ $3(x^{2} -4x+9)=0$

dividing both side by 3

⇒ $x^{2} -4x+9=0$

By using different factor, we can observe this trinomial can not be factored.

∴ solving it by completing the square.

⇒ $x^{2} -4x+9=0$

adding 9 on both side

⇒ $x^{2} -4x= 9$

To get a perfect square number as coeffecient of x is 4, lets add both side by 4.

⇒ $x^{2} -4x+4= 13$

we know, $(x+2)^{2} = x^{2} +2\times x\times 2+2^{2}$

∴ $(x+2)^{2} =13$

Taking Square root on both side, remember; √a²= a

⇒ $(x+2)= \sqrt{13}$

opening parenthesis

⇒ $x+2= \sqrt{13}$

subtracting both side by 2

∴ x= $-2 \pm \sqrt{13}$

Please help. 50 Points.

Ronch [10]

Answer:

0.8745.

Step-by-step explanation:

P(success) = 0.09 and P(failure) = 1 - 0.09 = 0.91.

P( at least 6 failures) = P( less than 2 successes)

= 7C0 (0.09)^0 (0.91)^7 + 7C1 (0.09)(0.91)^6

= 0.5168 + 0.3577

= 0.8745.

What is the difference of the fractions? Use the number line to help find the answer. One-half minus 1 and one-fifth A number li

ANEK [815]

Answer:

<h3>Negative StartFraction 7 over 10 EndFraction </h3>

Step-by-step explanation:

Given the expression $\frac{1}{2} - 1\frac{1}{5}$ , we are to find the difference

First convert the mixed fraction $1\frac{1}{5}$ to improper fraction

$1\frac{1}{5}$ = $\frac{6}{5}$

The expression becomes;

$\frac{1}{2} - \frac{6}{5}$

Find LCM

$\frac{5-6}{10}$

Evaluate the resulting expression

$\frac{5-12}{10}\\\\\frac{-7}{10}$

Hence the correct option is C i.e Negative StartFraction 7 over 10 EndFraction
