<span>|7x-7|+3 = 4x+1 ⇒⇒⇒ add (-3) to both sides
</span>
<span>∴ |7x-7| = 4x - 2
</span>
According to the absolute rule
∴ 7x - 7 = 4x - 2    OR    -(7x - 7) = 4x - 2
7x - 4x = 7 - 2      l     7x - 7 = -4x + 2
   3x = 5          l     7x + 4x = 2 + 7
x = 5/3                   l     11 x = 9 ⇒⇒⇒ x = 9/11

∴ x = 5/3 and 9/11

So, the correct answer is option <span>B. 5/3 and 9/11</span>

If g(x)*x+1/x-2 abd h(x)=4-x, what is the value of (g*h) (-3)

kifflom [539]

Answer:

The value of (g*h) (-3) is $=-\frac{112}{3}$

Step-by-step explanation:

If $g(x) = x+\frac{1}{x}-2$ and $h(x)=4-x$

We have to find (g*h) (-3)

First multiply g(x) with f(x)

$(x+\frac{1}{x}-2)\times (4-x)$

$Distribute\:parentheses$

$=x\cdot \:4+x\left(-x\right)+\frac{1}{x}\cdot \:4+\frac{1}{x}\left(-x\right)+\left(-2\right)\cdot \:4+\left(-2\right)\left(-x\right)$

$\mathrm{Apply\:minus-plus\:rules}$

$+\left(-a\right)=-a,\:\:\left(-a\right)\left(-b\right)=ab$

$=4x-xx+4\cdot \frac{1}{x}-\frac{1}{x}x-2\cdot \:4+2x$

simplify

$=-x^2+6x+\frac{4}{x}-9$

Now, put x= -3 in above expression

$=-(-3)^2+6(-3)+\frac{4}{-3}-9$

$=\left(-\frac{1}{3}-3-2\right)\left(4+3\right)$

$=\left(-\frac{16}{3}\right)\left(4+3\right)$

$=7\left(-\frac{16}{3}\right)$

$=-\frac{16}{3}\cdot \:7$

$=-\frac{112}{3}$

Therefore, the value of (g*h) (-3) is $-\frac{112}{3}$

46=f/10 – (-43) f = ?

Oksana_A [137]

46 = f/10 - (-43)
46 = f/10 + 43
f/10 = 46 - 43
f/10 = 3
f = 3*10
f = 30

In the first quadrant you start at (7,3) and move 5 unit left

AveGali [126]

Answer:

That would be (2,3)

Step-by-step explanation:

When we're moving left in the coordinate plane, we are subtracting the x-coordinate by how much distance we move.

In this case, 7-5=2, so the new x-coordinate is 2, but the y-coordinate doesn't change since we're going horizontally and not vertically.
