HELP PLEASE!!! 25 Points & Brainliest!

Answer:

(1) $f(x)=3x+4$

Ad g(x) represent f(x) after horizontal translation 2 units to the left.

$g(x)=3(x+2)+4$

$g(x)=3x+6+4$

$g(x)=3x+10$ is the required translation.

(2) $f(x)=\frac{-2x}{3}+2$

$f(\frac{1}{2})=\frac{-2}{3}\cdot(\frac{1}{2})+2$

$f(\frac{1}{2})=\frac{5}{3}$

(3) We have been given a point (1,-9); slope 2

We will use the equation:

$y-y_1=m(x-x_1)$

m is the give slope.

$y-(-9)=2(x-1)$

$y+9=2(x-1)$

Therefore, Option (a) is correct.

Explain how to find the vertex of 2x^2+12x+16

Elina [12.6K]

The vertex form:

$y=a(x-h)^2+k\\\\(h,\ k)-vertex$

Use $(a+b)^2=a^2+2ab+b^2\qquad(*)$

$2x^2+12x+16=2(x^2+6x)+16=2(x^2+2(x)(3))+16\\\\=2(\underbrace{x^2+2(x)(3)+3^2}_{(*)}-3^2)+16=2((x+3)^2-9)+16\\\\=2(x+3)^2+(2)(-9)+16=2(x+3)^2-18+16\\\\=\boxed{2(x-(-3))^2-2}\to h=-3,\ k=-2$

<h3>Answer: (-3, -2).</h3>

Other method:

$f(x)=ax^2+bx+c\\\\vertex:(h,\ k)\\\\h=\dfrac{-b}{2a},\ k=f(h)$

We have

$f(x)=2x^2+12x+16\\\\a=2,\ b=12,\ c=16$

Substitute:

$h=\dfrac{-12}{(2)(2)}=\dfrac{-12}{4}=-3\\\\k=f(-3)=2(-3)^2+12(-3)+16=2(9)-36+16=18-36+16=-2$

<h3>Answer: (-3, -2).</h3>

Please simplify <br> ....

Natalka [10]

Answer:

3 + x $\sqrt{3}$

Step-by-step explanation:

Note that $\sqrt{a}$ × $\sqrt{a}$ = a

Given

$\sqrt{3}$ ( $\sqrt{3}$ + x ) ← distribute parenthesis by $\sqrt{3}$

= $\sqrt{3}$ × $\sqrt{3}$ + $\sqrt{3}$ × x

= 3 + x $\sqrt{3}$

2x+3y=6 x+2y=5 elimination

ValentinkaMS [17]

In this equation you can eliminate the x value
multiply the second equation by -2 and you get:
-2x - 2y = -10
when you add the two equations the x factors will cancel

2x + 3y = 6
- 2x - 2y = -10
---------------------
y = 16

you can find the x value by plugging the y value that you now know into one of the equations that you started off with.
