Answer:
True
Step-by-step explanation:
Answer:
the equation of the line is 7x + y = 0 .
Step-by-step explanation:
in the standard form of the line that is Ax +By = C we can write it in the form of
By = C - Ax

which is in the form of 
where m is the slope of the line and c is y intercept made by the line.
comparing
and 
we get that
and 
since it is given that slope of the line is -7 therefore m = -7 and c = 0
therefore
and 
therefore C = 0 , A = 7 and B = 1
therefore the equation becomes 7x + y = 0
Two triangles must be congruent by SSS when their all sides would be equal.
So, BC = DF
AC = DE
Then, AB = EF = 10
In short, Your Answer would be Option B
Hope this helps!
Answer:(
(1,0),(-3,0)
Step-by-step explanation:
Answer:
4 pencil & 2 ruler = $8
2 pencil & 4 ruler = $10
let the no. of Pencil be X and no. of ruler be Y
4x + 2y = 8
2x + 4y= 10
solving the equation by elimination method,
multiplying eq 2 with 2
4x + 2y = 8
4x + 8y = 20
subtracting,
- 6 y = -12
y = 2
2x + 4(2)= 10
2x + 8 = 10
2x = 10 - 8
2x = 2
x = 1
Cost of 3 ruler + 3 pencil
= 3(1) + 3(2)
= 3 + 6
= 9
<h2 /><h2>= $9</h2>
