Answer:
1/7
Step-by-step explanation:
When 2 lines are perpendicular the gradient of one is the reciprocal of the other :
If the gradient of A was 2 the gradient of B would be 1/2.
If the gradient of a is 7 the gradient of b would be 1/7 .
Hope this helped and have a good day
Answer:
b=120
c=60
d=60
Step-by-step explanation:
Vertical angles are congruent . 180-120= 60. Sorry the explanation isn't that good.

Answer: -3x^2+17x-20
Answer:
y =
Step-by-step explanation:
From the table given in the picture,
Two points lying on the graph are (-4, 6) and (-2, 7)
Let the linear function is,
y = mx + b
Here, m = slope of the line
b = y-intercept
Since, slope of a line passing through two points and is given by,
Slope (m) =
Therefore, slope of the line passing through (-4, 6) and (-2, 7) will be,
m =
m =
y-intercept is a point for which x = 0
From the given table,
For x = 0, y = 8
Therefore, y-intercept (b) = 8
Equation of the linear function will be,
y =
