So when you are trying to find the solution to the system of equations make sure that you have it where y= -4/5x-6 and y= -30 are written like this:
-30=-4/5x-6
And then solve for x:
Add 6 on both sides.
-24=-4/5x
Then multiply by the reciprocal of -4/5.
-5/4*-24=-5/4*-4/5x
x=30
But then you are gonna want to plug 30 in for x in y=-4/5x-6 to make sure that it is the same as y=-30.
Answer:
x=58, m<DCB=56°
Step-by-step explanation:
Ok the sum of those two angles should equal 180 degrees so,
2x+8+x-2=180
solve the equation
3x+6=180
3x=174
x= 58
M<DCB=x-2--> 58-2=56
To be honest with u I think that u need to multiply 10 times 48.. I think thats it not sure if is the 100% correct answer
43.54 divided by 3.5= unit rate
12.44
Answer:
5
Step-by-step explanation:
Substitute 2 in for x
|2+3| = 5
This would take the absolute value of the answer, or in other words once you solve the equation it will remove any negatives to return a positive number. I took the test and I have links to prove it.
