Answer:
4
Step-by-step explanation:
find the equation of the line:
slope = rise / run
rise is 20, run is 8
20/8 = 5/2
slope intercept form is y = mx + b
where m is slope and b is y int
y = 5/2(x) + b
use a point given to find b
44 = 5/2(16) + b
44 = 40 + b
b = 4
Answer:
No solution
Step-by-step explanation:
Equations:
x - 3y = -2
x - 3y = 16
Subtract:
0 - 0 = -18
Answer:
No solution
Answer:
52% and 7
Step-by-step explanation:
There are 25 squares of which 13 are shaded , then
× 100% = 13 × 4% = 52°
(b)
1 square represents
× 100% = 1 × 4% = 4%
Then 80% = 80% ÷ 4% = 20
That is for 80% , 20 squares require to be shaded
That is 7 more than the 13 already shaded
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.
If D is the midpoint of GH, then GH equals 2(DH) = 16
16 = 4x - 1
4x = 17
x = 17/4
x = 4.25
