Answer:

gradient \:  =  - 7

Step-by-step explanation:

y + 7x = 8 \\ y =  - 7x + 8

According to,

y = mx + c \\

<em>m</em><em> </em><em>=</em><em> </em><em>gradient</em>

<em>So</em><em>,</em>

<em>y =  - 7x + 8</em>

<em>m =  - 7</em>

Answer:

-7

Step-by-step explanation:

equation=y+7x=8

y=-7x+8

the gradient is always the x co-efficient

therefore the gradient is -7

If x-y=√3, x²-y²=√5 &amp; a²-a√3+1=0, then find out the value of x+y
Lemur [1.5K]

Answer:

√15/3

Step-by-step explanation:

x² - y² =√5

(x +y)*(x -y) = √5

(x +y) * √3 = √5

x+y  = √5 / √3

x +y = √5*√3 / √3*√3

x +y = √15/3

Exterior angle theorem
16x - 7 = 8x + 2 + 10x - 19    ===>  16x -7 = 18x - 17
16x - 16x - 7 = 18x - 16x - 17 ===> -7 = 2x - 17
-7 + 17 = 2x - 17 + 17             ===> 10 = 2x ======> 5 = x
Plug x in to each equation.
Angle P: 8(5) + 2 = 42 deg, Angle Q: 10(5) - 19 = 31
The sum of interior angles = 180. 180 - 42 -31 = 107 deg (angle of PRQ)
To check that line other angle : 16(5) -7 = 73 deg + 107 = 180 deg
