Use the drawing tools to graph this system of inequalities. Remember that isolating y is a helpful first step before graphing each inequality.
x + y > 4
2× - y > 2
Answer:
look at picture
Step-by-step explanation:
The graph that represents the inequality is given.
What is inequality?Inequality is a relationship where two expressions or values are not equal to each other.
For origin test, substitute x=0, y=0 into the first inequality.
0+0>4
Since the obtained inequality is not true, the origin will not be included in the shaded region.
For origin test, substitute x=0, y=0 into the second inequality.
2(0)-0>2
0>2
Since the obtained inequality is not true, the origin will not be included in the shaded region.
In both inequalities, since the equal to "=" sign is not included, the lines will be dotted.
Plot the dotted lines, x+y=4 and 2x-y=2 on the same graph and shade the region not including the origin.
Thus, the graph of the given system of inequalities is given in the image.

Step-by-step explanation:
Solve the system of equations -x+y=15−x+y=15 and -5x-3y=27−5x−3y=27 by combining the equations
Answer:
Solution: x= -36, y=51
Step-by-step explanation:
Solve the system:
x + y = 15
-5x - 3y = 27
By using the reduction method.
Multiply the first equation by 3:
3x + 3y = 45
Add it to the second equation:
3x - 5x = 45 + 27
Simplifying:
-2x = 72
Dividing by -2:
x = 72/(-2)
x = -36
From the first equation:
-36 + y = 15
Adding 36:
y = 15 + 36 = 51
y = 51
Solution: x= -36, y=51

If AD = 12 and AC = 4y-36, find the value of y
Answer:
y=12
Step-by-step explanation:
in that case, then 12 = 4y -36
12 =4y -36
12+36=4y
48=4y
48/4=y
12=y
answer :y=12
Answer:
y = 15
Step-by-step explanation:
Consider that the attached screenshot is the figure given in the problem. Also consider that DC = 12, due to the fact that AD = 12, and there is a midpoint at point D.
AD + DC = AC
12 + 12 = 4y - 36
24 = 4y - 36
+ 36 + 36
60 = 4y
60/4 = 4y/4

What is the value of X
Answer:
the answer is 70.
Step-by-step explanation:
Since x and 80 are non-adjacent co-interior angles with respect to ( 2x +10 )
So,
x + 80 = 2x + 10 ( sum of two non-adjacent co-interior angles is equal to the exterior angle of that triangle )
=> 80 - 10 = 2x - x *( switching sides of x and 10 )
=> 70 = x
So, the value of x is 70
x + 80 = 2x + 10 (exterior angle property)
2x -x = 80 -10
x = 70

NO
Step-by-step explanation:
x=1
y=2
2>1+3
2>4
Answer:
No it is not a solution
Step-by-step explanation:
1.)plug in the numbers to the equation y > x+3
After you plug it in solve:
-2 > 1 + 3
-2 > 4
this is false because 4 is greater than -2 so it should look like this -2<4
but because it doesn't, this is false

The equation we need is going to be 32,000 multiplied by 0.04% written as a decimal.
Since 0.04% written as a decimal is 0.004, the equation will be:
32000*0.004= ?
32000*0.004= 128.
