Answer:
x = 7 cm
Step-by-step explanation:
The two triangles are similar so ...
x/(6 cm) = (42 cm)/(36 cm)
Multiplying by 6 cm, you get ...
x = (6 cm)(42 cm)/(36 cm) = (6 cm)(7/6)
x = 7 cm

Answer:
(see attached workings)
y = -4x + 2
y = (4/5)x + 2/5
Step-by-step explanation:
- Rewrite the function to make y the subject.
- Find the x values of the points when y=-2 by substituting y=-2 into the rewritten function
- Differentiate the function
- Input the found values of x into the differentiated function to find the gradients of the tangents to the curve at y=-2
- Use the equation of a straight line and the points where y=-2 and the found gradients to find the equation of the tangent lines.

Answer:
10 times greater
In the first number, 3 represents 30,000, but in the second number 3 represents 3,000 so 30,000 is 10 times greater
Answer:
The answer would be (17,-6). It's just add to the original coordinates.
