Answer:
x= -2; x ≥ 2
Step-by-step explanation:
1. -3x+2=8
<u>Subtract +2 </u>on both sides
-3x+2<u>-2</u>=8<u>-2</u>
<u></u>
-3x=6 <u>Divide by -3 </u>on both sides
-<u>3x</u>/-3=6/<u>-3</u>
<u></u>
<u>x= -2 </u>
<u>-</u><u>2 is the answer for both the equation and inequality.</u>
<u />
<u>sorry i was lazy to do the inequality one, but it should be the same answer.</u>
<u />
<u>also ignore the fact that theres a line, i could not find the sign without one, o im sorry.</u>
<u></u>
<u></u>
You would divide 100/20 and get 5. then u would multiply 9 times 5 equals 45 then add a decimal to get ur answer 0.45
Angle 1 and angle 3 are vertically opposite angles. And both angles are congruent with each other.
<h3>What is an angle?</h3>
The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Line L and line M intersect each other.
Angle 1 and angle 2 are supplementary angles.
∠1 + ∠2 = 180° ...1
Angle 2 and angle 3 are supplementary angles.
∠2 + ∠3 = 180° ...2
From equations 1 and 2, then we have
∠1 + ∠2 = ∠2 + ∠3
∠1 = ∠3
The vertically opposite angles are angle 1 and angle 3. Furthermore, the two angles line up perfectly.

x represents the number of lawns weeded by Gwen and y represents the number of dogs walked by Fabio.
Gwen charges $12 each time she weeds a yard and Fabio charges $9 each time he walks a dog.
So, for x number of weeds, Gwen earned 12x and for y number of dogs walked, Fabio earned 9y.
They need at least $510 to purchase the new gaming station.
Therefore,
12x + 9y ≥ 510
Also, the number of dog walks that Fabio has scheduled should not be more than twice the number of yards Gwen has scheduled to weed.
Therefore,
y ≤ 2x
Also, Fabio will walk at least 25 dogs.
Therefore,
y ≥ 25
Hence, the constraints are:
12x + 9y ≥ 510
y ≤ 2x
y ≥ 25
