Find the slope of the line please help
Ne4ueva [31]

Answer:

0

Step-by-step explanation:

Plug 2 points into the equation y2-y1/x2-x1. In this case, I picked (0,-1) and (1,-1). This will make the equation -1--1/1-0. Simplify this to get 0/1 which is equal to 0. Therefore, the slope is 0.

-4x + 7y = 18
sasho [114]

Answer:

​​

Step-by-step explanation:

Subtract 7y7y from both sides.

-4x=18-7y−4x=18−7y

2 Divide both sides by -4−4.

x=-\frac{18-7y}{4}x=−

​4

​

​18−7y

In isosceles trapezoid JKLM, m∠J = 17x + 7, and m∠M = 11x + 13. Find m∠K.
tensa zangetsu [6.8K]

Answer:

m\angle K \approx 104.14^{\circ}

Step-by-step explanation:

In isosceles trapezoid JKLM,

Given: m\angle J = 17x+7 and m\angle M = 11x+13

Since, JKLM is an isosceles trapezoid so each pair of base angles is congruent.

m\angle J = m\angle K

m\angle M = m\angle L

As, we know that the sum of the angle of a trapezoid is 360^{\circ}

The angles are:

m\angle J = 17x+7

m\angle K = 17x+7

m\angle L = 11x+13

m\angle M = 11x+13

Therefore,

17x+7+17x+7+11x+13+11x+13 = 360^{\circ}

Combine like terms;

56x + 40 = 360^{\circ}

Subtract 40 from both sides we get;

56x + 40 -40 = 360 - 40

Simplify:

56x = 320

Divide both sides by 56 we get;

x = \frac{320}{56} = \frac{40}{7}

To find the angle of m\angle K:

m\angle K = 17x + 7 = 17(\frac{40}{7}) +7 = 97.14 + 7

Simplify:

m\angle K \approx 104.14^{\circ}

Therefore, the value of angle of m\angle K \approx 104.14^{\circ}
