Hey buddy I am here to help!
5. y = ax + b
-5 = a*4 + b
-5 = 4a + b
If we take a as -2
-5 = 4*-2 + b
-5 = -8 + b
b = -5 - (-8)
b = -5 + 8
b = 3
so... a = -2 and b = 3
6. (i) y = 5x - 2
(1,7)
y = 7 & x = 1
7 = 5*1 -2
7 = 5 - 2
7 = 3
so this point (1,7) is wrong
(ii) y = 5x -2
we can take any value for x...
e.g. x = 2
y = 5*2 - 2
y = 10 -2
y = 8
SO answer in this case would be (2,8)
Plz mark my answer brainliest
So, as you can see from the picture below
the line coming down from the right-angle, creates 3 similar triangles
a large, a medium and a small one
the large one, is the one containing the other two smaller ones... anyhow
to get "x", you can use proportions, either from large and medium or small and large so
solve for "x", either proportion will do
Answer:
It falls between 7 and 8.
Step-by-step explanation:
Since the = 7 and the = 8 it would make the fall in between 7 and 8.
