How do I graph this problem?

Mathematics
1 answer:
KIM [24]3 years ago
6 0
The easiest way to graph these equations is to place them in slope intercept form.
2x = 10 - 3y
3y + 2x = 10
3y = -2x + 10
y = -2/3x + 3 and 3/10
Then just place values in for x to determine y
If x = 0, y = -2/3(0) + 3 and 3/10; y = 3 and 3/10
x = 1; y = -2/3(1) + 3 and 3/10; y =  2 and 19/30
Repeat as needed for more points, then plot the points on the graph, and draw a line through the points.

The same can be applied to the second equation.
3x + 2y = 5
2y = -3x + 5
y = -3/2x + 2 and 1/2

x = 0; y = -3/2(0) + 2 and 1/2; y = 2 and 1/2
x = 1; y = -3/2(1) + 2 and 1/2; y = 1
Repeat as needed for more points, then plot points and draw a line through them.

a man divides ₹90,000 among wife son and daughter in the ratio 1/3:1/4:1/6 . find amount received them​
Pani-rosa [81]
The lowest common multiple of 3,4 and 6 is 12. Therefore if you multiply the ratio by 12 you get 12/3 : 12/4 : 12/6 which is equal to 4:3:2.
When you add 4,3 and 2 the answer is 9 therefore the £90,000 is split into 9 parts. £90,000 divided by 9 = £10,000 which means each part is £10,000.
The wife receives 4 parts so she receives 4 x £10,000 = £40,000
The son receives 3 parts so he receives £30,000
The daughter receives 2 parts so she receives £20,000

Draw diagarm

we want to know the hyptohuse
use cos

cos(x)=opositeside/hhyptohuse
hypothuse=length of ramp

cos(18°)=26/?
times both sides by ?
?cos(18°)=26
divide both sides by cos(18°)
?=26/(cos(18°))
use your calculator
?=27.338in

the ramp is about 27in

3(x+1)+ 5=2x- 2 <br>i need help with this equation​
aev [14]

Answer:

x = -10

Step-by-step explanation:

3(x+1) +5 = 2x -2

<em>Distribute the 3 to the x+1</em>

3x+3 +5 = 2x -2

<em>Combine like terms</em>

3x + 8 = 2x -2

<em>Subtract 2x from both sides</em>

x + 8 = -2

<em>Subtract 8 from both sides</em>

x = -10

Hope this helps!

Write the equation in standard form using integers.
ikadub [295]

Standard form is Ax +By =c

y = -4/5 x -7

multiply by 5

5y = -4x -35

add 4x to each side

4x +5y = -35

multiply by -1

-4x -5y = 35
