Hello :
x+4y = 28
multiply by : 2
2x+8y =56
same line (same graph)
the system is : <span>Dependent
when the solution is :
x = k .... k in R
y = -1/4 x +7</span>
Answer:
Step-by-step explanation:
Factor out to simplify:
15d+105=4d-16+11d
15d+105=15d-16
subtract 15d from both sides
105=-16
this means that there are no solutions for d
Answer:
125
Step-by-step explanation:
Percent means out of 100
125% = 125/100
False, I don't think it makes any sense.
the sum of all the angles = 180
13x-11 + 8x-9 + 30x-4 =180
51x-24 = 180
51x = 204
x=4
w= 8x-9= 8×4-9
= 2e°
