9:8 is the equivalent ratio
- It's very long so I'm not giving answers but here's how i would do it:
- use Pythagoras
where c is the longest side - use sine rule
where lower cases are the sides, and capitals are their opposite angles.
e.g for 15:
a = 3, b is missing, c = 10
A is missing, B is ?, C is 90
Answer:
659
Step-by-step explanation:
ones place is 9
tens + hundreds places = 11
two consecutive numbers that equal 11 are 5 and 6
hundreds is 1 + tens place so it is 6
and the tens is 5
Answer:
y=x+2
Step-by-step explanation:
To find the equation of a line or linear function, you need at least two points that lie on the line. This is to find the slope or gradient of the line if it's not given. Let's use the two points (0,2) and (-2,0). The first coordinate in each point is X and the second is the y coordinate.
GRADIENT/SLOPE=[y1-y2]/[x1-x2]
=[2-0]/[0-2]=1
The equation of a linear function is given. by Y-y1=m(X-x1)
Y-2=1(X-0)
Y=X+2
VERIFICATION OF SOLUTION
You may want to verify whether you are right by substituting values of x to see if you can obtain corresponding y values.
Example: if x=0, y=0+2=2.This confirms first point
