Answer:

X>-3/2

Step-by-step explanation:

To start off, you have to get x on one side and the numbers on the other. To do this, subtract 3 on both sides to get the +3 to the other side. After this you should have X-3X<3. Now that you have all the x values on one side, subtract them to get-2X. Now your equation is -2X<3. Now you divide to not have a coefficient before X. To do this divide by -2. Keep in mind that when you divide by a negative number in an inequality, the sign flips. Because of this your answer would be X>-3/2.

Answer:

x > -3/2

Step-by-step explanation:

x-3x+3<6

Combine like terms

-2x+3<6

Subtract 3 from each side

-2x +3-3<6-3

-2x <3

Divide each side by -2,remembering to flip the inequality

-2x/-2 > 3/-2

x > -3/2

The point (-3/5,y) in the third quadrant corresponds to angle θ on the unit circle.

romanna [79]

Sec(theta) = 1 / cos (theta) = hypotenuse / x -coordinate

hypotenuse = 1 (because it is the radius of the unit circle)

sec (theta) = 1 / (-3/5) = - 5/3

cot (theta) = 1 / tan(theta) = x-coordinate / y - coordinate

cot (theta) = -3/5 / y

y^2 + (-3/5)^2 = 1 => y^2 = 1 - 9/25 = 16/25 = y = +/- 4/5

Third quadrant => y = -4/5

=> cot (theta) = (-3/5) / (-4/5) = 3/4

70% of a number is 98.

hammer [34]

The solution is as follows:

Set up the proportion:

70% - 98
90% - x

70% / 90% = 98 / x

7 / 9 = 98 /x

(7 / 9) x = 98

x = 98 x 9/7

x = 14 x 9

x = 126

The answer is D. 126.

I hope my answer has come to your help. God bless and have a nice day ahead!
