4 0

Answer:

<em>-14x+6</em>

Step-by-step explanation:

first, we distribute the -3.

-3(4x - 2) - 2x=-12x+6-2x

than, we conbide like terms

-12x+6-2x=-14x+6

Robin purchased a piece of land in the year 2000 for $15,000. The value of the land increases at the rate of 13.17% each year. I
-Dominant- [34]
The value of the land increases by 13.17% each year So it's growth function which is V (t)=15000 (1+r)^t Where r is the growth rate which is in decimal 13.17/100=0.1317 So it's D) V(t) = 15000(1.1317)t; growth

4x + 7x - 2 + 5x - 10 find the value of x
valina [46]

Answer:

x = 4/5

Step-by-step explanation:

1) Group like terms

   4x + 7x + 5x - 2 - 10 = x

2) Add similar elements

   16x - 2 - 10 = x

3) Subtract

   16x - 12 = x

4) Add 12 to both sides

   16x - 12 + 12 = x + 12

5) Simplify

   16x = x + 12

6) Subtract x from both sides

   16x - x = x + 12 - x

7) Simplify

   15x = 12

8) Divide both sides by 15

    15x/15 = 12/15

9) Simplify

   x = 4/5

Given sintheta =7/11 and sectheta is less than 0, find costheta and tantheta
Korvikt [17]

Answer:

Step-by-step explanation:

Sin theta is the ratio of side opposite over hypotenuse of a reference angle situated at the origin in an x-y coordinate plane.  If sec theta is negative, then the only quadrant where sin is positive AND sec is negative is quadrant 2.  Remember that sec theta is the inverse of cos theta.  Puttling our right triangle in QII, the side measuring 7 is across from the angle and the hypotenuse is 11.  In order to find the cos theta and tan theta, we need the side adjacent to the angle.  Use Pythagorean's Theorem to find the side adjacent.

11^2=7^2+x^2 and

121=47+x^2 and

72=x^2 so

x=6\sqrt{2}

Remember that this value is why the sec is negative.  Because x is negative in QII, the cos theta is side adjacent over hypotenuse:

cos\theta=-\frac{6\sqrt{2} }{11}  and

tan\theta=-\frac{7}{6\sqrt{2} }

But we should probably rationalize that denominator, so

tan\theta=-\frac{7}{6\sqrt{2} }*\frac{\sqrt{2} }{\sqrt{2} } =-\frac{7\sqrt{2} }{12}
