The slope of the first equation has a slope of one and a y intercept of -4. The second equation has a y intercept of -2.3333 as seen when plugging in 0 for x, so the same y-intercept and same line are out of the question. This means either they have the same slope and thus are parallel or intersect at some point. A simple way to find out? Plug in 1 for x on the second. If it isn't -1.33333, which is a slope of positive 1 such as in the first equation, they WILL INTERSECT somewhere. When plugging in 1, we get
3y - 1 = -7
3y = -6
y = -2
(1, -2) is the next point after (0, -2.3333)
That means it is most certainly not the same slope, and thus they will intersect at some point. The two slopes are 1/1 and 1/3 if you weren't aware.
2x+38=50
2x+38-38=50 -38
2x =12
2x/2 =12/2
x=6
Answer:
1/14:5/7:3/14
Step-by-step explanation:
Since orange=15
Apple=5
Coconut milk=50
50+15+5
70
So
Orange=15/70
Divide both by 5
=3/14
Apple=5/70
Divide both by 5
=1/14
Coconut milk=50/70
Divide both by 10
=5/7
So the ratio of apple to coconut to orange
1/14:5/7:3/14
c) opposite edges of a computer screen
Let S be the first side.
Longest side is then 2S.
Third side is 2S-10.
Perimeter is sum of all three sides = S+2S+2S-10 = 75
=>
5S-10=75
5S=75+10=85
S=17
Therefore
S=17 is the first side.
Longest side is then 2S=2*17=34.
Third side is 2S-10=2*17-10=24.
