<u>Part A:</u>
lines y=-2x+9 and 4x+2y=4 can be used to create a system of equation that has no solution because none of the lines intercept on a graph.
<u>Part B:</u>
lines y=2x+2 and 6x-3y=6 can be used to create a system of equation that has infinitely many solutions because again none of the lines intercept on a graph
<u>Part C:</u>
The lines y=1/2x+1 and 4x+2y=4 can be used to create a system of equations with one solution because on a graph both lines intersect at one point.
The Graphs Are Shown Below.
HIgh Hopes
Barry-
X - 5y = 0 (1)
15x + 10y = 17 (2)
From (1),
2x - 10y = 0 (3)
(2) + (3),
17x = 17
x= 1
Sub x=1 into (1)
x - 5y = 0
- 5y = -1
y = 1/5
Therefore x = 1, y = 1/5.
Hope it helps : )
Answer:
Im guessing this means 20% of 0.5, in that case it is 0.1
Step-by-step explanation:
you can use a calculator and put 0.2*0.5
But also in your head you can do whats 20% of 5, so what times 5 equals 5? 1
so 1/10 is 0.1 giving you your answer
Answer:
The measurement was off by 0.7%
Step-by-step explanation:
To find the relative error in the measurement, start by finding the difference.
36 - 35.75 = 0.25
Now divide that by the actual measurement of the door.
0.25/35.75 = 0.7%
Answer:
1,000 different combinations are possible
Step-by-step explanation:
Because if youre lock ckntained 3 single digit numbers it would have to be 0-9 so each digit would have 10 options so there would be 1,000 different combinations that are possible.
