Given:
The equation 
goes through the coordinates (6,5) and (-2,-5).
To find:
The values of A and B.
Solution:
We have,
It goes through the coordinates (6,5) and (-2,-5). It means these points will satisfy the equation.
...(i)
...(ii)
Adding (i) and (ii), we get
Divide both sides by 4.
Put A=5 in (i), we get
Divide both sides by 5.
Therefore, the values of A and B are 5 and -4 respectively.
Answer:
11,36 pounds
Step-by-step explanation:
Trayvon's weight on earth= 142 pounds
Trayvon's weight on Saturn= (0,92)*Trayvon's weight on earth=
(0,92)*142=130,64 pounds
The difference between Trayvon's weight on earth and Saturn:
Trayvon's weight on earth- Trayvon's weight on Saturn
142-130,64=11,36 pounds.
-16w-26+9w=-61
-16w+9w=-61+26
-7w=-35
w=5
Answer: 51m²
Step-by-step explanation:
To solve this type of problem , you first of all consider the diagram asba complete block.The diagram is a complete block or rectangle upon which a triangle is superimposed. To find the area of the shaded region , just find the area of the whole block and removed the area of the triangle that was superimposed.
Now, let move to the real work
Area of the whole block
= length × breadth
= 7m × 9m
= 63m²
Step ii,
Area of the right angle triangle
= (1/2)bh
= 1/2 × b × h
Now to get the dimensiona of the triangle, we need to do some deductions. Since the widths of the triangle is 9m, therefore, the height of the triangle wil
= 9m - 3m
= 6m.
h = 6m.
Since the length of the triangle is 7m, therefore, the base of the triangle will be
= 7m - 3m
= 4m.
Step iii, to find the area of the triangle now , we applied the formula.
Area = 1/2 × 6 × 4
= 12m².
Now to find the area of the shaded region , we carry out subtraction
Area = 63m² - 12m²
= 51m².
