Answer:
x=7, y=16
Step-by-step explanation:
2x+5=x+12
2x=x+7
x=7
y-4=x+5
y-4=12
y=16
Answer:
I can use any function I want to and can still have that domain and range
Step-by-step explanation:
<h3>
Answer: x > -8</h3>
Multiply both sides by 2 so that you go from
x/2 > -4
to
x > -8
The inequality sign will not flip since we are not multiplying both sides by a negative number.
If you are curious how to graph the solution, draw out a number line and plot an open unfilled circle at -8. Then shade to the right of the open circle. The open circle says "do not include this value as part of the solution set". The solution set is shaded representing all of the values larger than -8 (which make the original inequality true).
It's not 6 its literally just above 6 its ( 6.25 )
Answer:
45 and 135
Step-by-step explanation:
If angles, with measurements a and b, are supplementary, then a and b have sum 180 degrees.
So we have the following equation so far:
a+b=180
Now we also have that one angle has a measurement that is 1/3 the value of the one.
So we also have 3a=b which means we are letting the angle whose measurement be a have 1/3 the value of b.
So lets plug the second equation into first giving us:
a+3a=180
Add like terms:
4a=180
Divide both sides by 4:
a=180/4
a=45
So b=3a=3(45)=135.
So the angles in question have measurement s 45 and 135.
