Answer: m<DCB= 50 degrees
Step-by-step explanation:
120= (15x+5)+(22x+4)
120= 37x+9
111= 37x
x=3
15(3)+5
45+5=
50
Answer:
y = -4/3x -2
Step-by-step explanation:
Slope intercept for is y = mx+b where m is the slope and b is the y intercept
4x+3y=-6
We need to solve for y
Subtract 4x from each side
4x-4x+3y=-4x-6
3y = -4x-6
Divide each side by 3
3y/3 = -4x/3 -6/3
y = -4/3x -2
The slope is 4/3 and the y intercept is -2
Answer:
x =-1 i think
Step-by-step explanation:
-3/4x + 5/6 y = 15
Multiply through by 6
-9/2x + 5y = 90
Add 9/2x to both sides
5y = 90 + 9/2x
Divide both sides by 5
y = 18 + 9/10x
y = 9/10x + 18
Comparing with the general equation of a straight line y = mx + c
Gradient (m) = 9/10 or 0.9
and the y - intercept (c) = 18
Answer:
In triangle EFG,
EG = 4.8 units
Since angle FDE = angle FED,
EF = FD = 3.5 units [sides opposite to equal angles]
FG = DE = 3 units [Given]
s = (a+b+c)/2
= (EG+EF+GF)/2
= (4.8+3.5+3)/2
= 11.3/2
now using Heron's formula,
area of EFG =
