The question is in the picture

Fudgin [204]

Answer:

(x) = 1/2x-3/2

Step-by-step explanation:

The inverse is the opposite of the equation given in this case is 2x+3 and the inverse is when you switch the x and the y and you solve for y.

Which has the least absolute value? A. 5 B. 30 C. -10 D. -50

ziro4ka [17]

Absolute value means the total distance from zero. So you get rid of any negative signs and then look at which number has the lowest value (which is the smallest number without any negative signs).

Find the measure of Angle B A. 50° B. 55° C. 60° D. 65°

kondaur [170]

Option B. 55° is the correct answer

Step-by-step explanation:

"The sum of interior angles of a triangle is always 180°"

Given

m∠A=(3x+1)°

m∠B=(2x-1)°

m∠C = 40°

We know that

m∠A+m∠B+m∠C=180°

Putting the values of angles

$(3x+1) +(2x-1) +40 = 180\\3x+1+2x-1+40 = 180\\5x+40=180\\$

Subtracting 40 from both sides

$5x+40-40=180-40\\5x=140$

Dividing both sides by 5

$\frac{5x}{5} = \frac{140}{5}\\x=28$

We have to find Angle B,

m∠B = 2x-1 = 2(28)-1 = 56-1 = 55°

Hence,

m∠B=55°

Option B. 55° is the correct answer
