What would be the slope of equation #1 in the following system? (Graphing)
2x+3y=12
4x-3y=15
(Worth 10 points )
A:1/2
B: -1
C:3/4
D:-2/3
Answers
Answer:
[tex]m = -\frac{2}{3}[/tex]
Step-by-step explanation:
Given
[tex]2x+3y=12[/tex]
[tex]4x-3y=15[/tex]
Required
Slope of #1
[tex]2x+3y=12[/tex]
Make y the subject
[tex]3y = -2x + 12[/tex]
Divide through by 3
[tex]y = -\frac{2}{3}x + \frac{12}{3}[/tex]
[tex]y = -\frac{2}{3}x + 4[/tex]
An equation has the form:
[tex]y = mx + c[/tex]
Where
[tex]m = slope[/tex]
Compare [tex]y = mx + c[/tex] and [tex]y = -\frac{2}{3}x + 4[/tex]
[tex]m = -\frac{2}{3}[/tex]
Hence, the slope is [tex]-\frac{2}{3}[/tex]

solve the system of equations 2x+7y=-5 and-x-6y=10
Answers
Answer:
x=8 and y= -3
Step-by-step explanation:
2x + 7y= -5. eqn 1 ×6
-x -6y = 10. eqn 2 ×7
12x + 42y = -30
+
-7x - 42y = 70
= 5x= 40
x= 8
to find y
substitute x into eqn 2
-8-6y=10
-6y=10+8
-6y=18
therefore 6=-3
A motorist takes 5 hours
to travel & 300km, how
Long will it take to bravel
720 km at sume
average Speed?
Answers
Answer:
12 hours.
Step-by-step explanation:
A motorist takes 5 hours to travel 300km
This means that his velocity, in km per hour, is given by:
v = 300/5 = 60 km/h
How long will it take to travel 720 km at same average speed?
720 km, 60 an hour. So
720/60 = 12
It will take 12 hours.

Weight of a pile of sand = 90 Kg
Ratio of weight of sand in three bags =
2 : 3 : 7
Let the weights be 2x kg, 3x kg and 7x kg respectively
A.T.Q.
=> 2x + 3x + 7x = 90

Danny reads for one half hour every day.
At the end of four weeks, how many hours has Danny read?
Answers
There are 7 days in a week.
1/2 hour x 7 days = 3 1/2 hours per week.
3 1/2 hours per week x 4 weeks = 14 hours
He read for a total of 14 hours
Answer:
14 hours
Step-by-step explanation:
half hour = 30 minutes
1 week = 7 days
30(minutes) x 7(days) = 210 minutes
210(minutes) x 4(weeks) = 840 minutes
Now we know how much time Danny has read (840 minutes), but we need to know what that is in hours.
840 minutes = how long Danny has read in minutes
60 minutes = hour
840(minutes) ÷ 60(minutes) = 14(hours)

85-v=213
solve for v
Answers
Step-by-step explanation:
subtract the whole equation by 85 on both sides to get v by itself on the left side
85-85-v=213-85
-v=128
Now we divide the whole equation by negative 1
-1v/-1=128/-1
v=-128
