Answer:

y = 105°

Step-by-step explanation:

In an isosceles trapezoid.

Any lower base angle is supplementary to any upper base angle, that is

y = 180° - 75° = 105°

Answer:

S=R

75+75=150

360-150=210

210/2=105

y=105

2(x-3)-12 = -4<br> How do I solve this equations
deff fn [24]

Answer:

x= 7

Step-by-step explanation:

1st step: Multiply the factor (outside number) with the numbers and variable(s) in the box. This results in 2(x-3) = 2x-6

2nd Step: continue the rest of the equation since there are no more brackets left so 2x-6-12=-4

3rd Step: send -12 to the other side of the equation (side changes sign changes) so it will become 2x-6=-4+12    (You are actually supposed to make the variable alone on one side of the equation so that you would be able to calculate its value)

4th step: 2x-6=8 ---> send -6 to the other side as well which will then result in 2x=14

5th step: since 2 is being multiplied by x, when you send it to the other side (to make x alone) you will divide 14 by 2 ( sign of 2 changes from multiplication to division)

Final Step: x=7

Answer:

1.) slope=2

2.) slope=-3

3.) slope=\frac{1}{4}

4.) slope=-\frac{4}{5}

Step-by-step explanation:

The unit rate is also known as slope. Slope is the change in the y values over the change in the x values:

(x_{1},y_{1})\\\\(x_{2},y_{2})\\\\\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=slope

However, with certain graphs, the slope can be found in a simpler manner.

  • You start at one point and move across the y-axis, then move along the x-axis until you reach another point on the same line.
  • Make sure you move on the y-axis first, then the x-axis. Record the slope as spaces moved in each \frac{y}{x}
  • When you move up, the number will be positive (\frac{+y}{x}). If you move down, the number will be negative (\frac{-y}{x}).
  • If you move to the right, the number will be positive (\frac{y}{+x}). If you move to the left, the number will be negative (\frac{y}{-x}).
