For the triangle picture:
2/6 = 5/x
2x = 30
x = 15
For the other picture:
3.2/2 = a/8
The third option applies.
Other option does not apply.
Because for Option 4,
It should be 2/3.2 = b/6.4
For option 3,
it should be b/6.4 = 5/8
Answer:
a) The discounted prince is 70% of the full price.
b) 32.5 €
Step-by-step explanation:
a) If the full price is 100%, then you subtract 30% which is the discount and you get 70 %.
b) 22.75 is 70% of 32.5

4^x is an exponential function with base 4 and exponent x; its graph is entirely above the horizontal axis, and the curve representing 4^x continues to rise as x increases. Its y-intercept is (0,4^0), or (0,1).
Find slope
slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given
(-1,5) and (5,8)
slope=(8-5)/(5-(-1))=3/(5+1)=3/6=1/2
y=1/2x+b
sub a point
(-1,5)
x=-1, y=5
5=1/2(-1)+b
5=-1/2+b
add 1/2
5 and 1/2=b
y=1/2x+5 and 1/2
y=1/2x+11/2
