Easy question.
So, the slope is -x and the y-intercept is at -4.
y = -x - 4
Use this equation and you will find:
y = -2 - 4
y = -6
Answer: (2, -6)
-2k - (-7)k
= -2k + 7k
= 5k
-7(p + 2) + 9(p - 4)
= -7p - 14 + 9p - 36
= 2p - 50

Step-by-step explanation:
Enlarge the triangle ABC by a scale factor of 2 about the centre of enlargement O.
First, draw ray lines from O to each corner of the triangle and extend them.
Next, measure the distance from O to each corner of ABC. ...
Finally, join up the points A' B' C'
Locate the Centre of Enlargement, then draw Ray Lines from the centre of enlargement through the vertices of the shape. If a shape is being enlarged by a scale factor of 2, the distance from the centre of enlargement to each vertex will be twice the size. The size of the shape will also be twice the size.
Answer:
7/12
Step-by-step explanation:
First you have to find a comnon demominator, which is 12.
Next, add them together.
the equation is - tan2 x + sec2 x = 1.
Left hand side identity : - tan2 x + sec2 x.
Trigonometric function : tan x = sin x / cos x,
Reciprocal identity : sec x = 1/cos x.
- tan2 x + sec2 x = - (sin x/cos x)2 + (1/cos x)2
= - sin2 x/cos2 x + 1/cos2 x
= (1 - sin2 x)/cos2 x
Pythagorean identity : sin2 x + cos2 x = 1 .
= cos2 x / cos2 x
= 1
