Answer:

1 and - 1

Step-by-step explanation:

The equation of a line passing through the origin is

y = mx ( m is the slope ( gradient ) )

y = x ← is in this form

with gradient m = 1

Parallel lines have equal gradients

Then the gradients of lines parallel to the given line is 1

Given a line with gradient m then the gradient of a line perpendicular to it is

m_{perpendicular} = - \frac{1}{m} = - \frac{1}{1} = - 1

Then the gradients of lines perpendicular to this line is - 1

2 A and B please with explanation! BIG POINTS please explain
dedylja [7]

Answer:

see explanation

Step-by-step explanation:

Using the ratio equality for circles

\frac{arc}{C} = \frac{angleatcentre}{360}

(a)

Note the angle at the centre of the shaded arc is 360° - 90° = 270°, thus

\frac{45}{C} = \frac{270}{360} = \frac{3}{4} ( cross- multiply )

3C = 180 ( divide both sides by 3 )

C = 60 mm

(b)

Note the angle at the centre of the shaded arc is 360° - 135° = 225°, thus

\frac{3.3}{C} = \frac{225}{360} ( cross- multiply )

225C = 1188 ( divide both sides by 225 )

C = 5.28 cm

fenix001 [56]

Answer: 7

Step-by-step explanation:

Step 1: Subtract 3 from both sides.

6a+3−3=45−3

6a=42

Step 2: Divide both sides by 6.

6a /6 = 42 /6
