What is the slope of the line that passes through (-3,4) and (-3,-4)
suter [353]

Answer:

undefined

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

    = ( -4-4)/( -3 - -3)

   = ( -4-4)/( -3+3)

   = -8/0

When we divide by zero, the answer is undefined so the slope is undefined

Please help, thank you! ​

we know angle RLP= 100⁰

also

angle RLP+ angle RLB=180⁰(Linear pair)

=>100⁰+angleRLB= 180⁰

=> angle RLB=80⁰

since BR and LR are equal, angle RBL and angle RLB are equal

therefore angle RBL is also equal to 80⁰

using angle sum property of triangles we know that the sum of all angles in a triangle is equal to 180⁰

=>angle BRL+angle RBL+angle RLB= 180⁰

=> angle BRL+80⁰+80⁰=180⁰

=>angle BRL = 180⁰-160⁰

=>angle BRL= 20⁰

I'm sorry it took me some time I'm a slow typer

I load of bricks is twice as heavy as a load of sticks the total weight of four loads of bricks and four loads of sticks is 771
Anastasy [175]

9514 1404 393

Answer:

  321.25 kg

Step-by-step explanation:

The given relations are ...

  b = 2s

  4b +4s = 771

Substituting for b, we have ...

  4(2s) +4s = 771

  12s = 771

  s = 64.25

  b = 2s = 128.50

Then the weight of interest is ...

  b +3s = 128.50 +3(64.25) = 321.25 . . . . kg
