hope it helps this to you figthing sheeeeeeeeeeeeeeeeeeeeeeeesh!!!
The only answer is x = 4, y = 2,
2(4) + 6(2) = 20
3(4) _ 2(2) = 8
the graph is so easy, please try!!
Answer:

Step-by-step explanation:
The equation of a line has the following format:

In which m is the slope and b is the y-intercept(value of x when y = 0).
In this question:
Slope 4, which means that
.
So

Contains point (1,-8).
This means that when
. We replace this into the equation to find b. So



So

Answer:
126
Step-by-step explanation:
Let x be the missing length
The triangles are similar:
● UE/140 = 45/x
From the graph we deduce that:
● UE = 140 - 90 = 50
Replace UE by its value
● 50/ 140 = 45/x
Switch x and 50
● x / 140 = 45/50
45/50 is 9/10 wich is 0.9
● x/140 = 0.9
Multiply 0.9 by 140
● x = 140 × 0.9
● x = 126
Since the diver is 19 metres below the surface of the water, then he will need to travel 19 metres to reach the surface.
