Answer:
1 - 2x
Step-by-step explanation:
Simplify the expression.
1x + 3 - 3x + (-2)
Bring all the like terms together.
= 1x - 3x + 3 - 2
Simplify again.
= 1 - 2x
Answer:
2(1.5)+3(0)+4(0)=3
3(-2)+4(-1.75)+2(0)=-13
3+5(2)+3(3)=22

Answer:
The answer to your question is: BD = 7.5
Step-by-step explanation:
Data
C is the midppoint of AD
B is the midpoint of AC
AC = 5
BD = ?
Process
We know that B is the mid point of AC, then AB = BC
AB + BC = 5
but 2AB = 5
AB = 5/2
AB = 2.5 = BC
Then AC = CD if AC = 5 then CD = 5
Finally
BD = BC + CD
BD = 2.5 + 5
BD = 7.5
No, it is not in the solution area for the system.
The point only works in one of the inequalities.
It doesn't work in the inequality: y > -1/2x+ 3
We can put it in to test it:
-7 > (-1/2)3 + 3
-7 > -1.5 + 3
-7 > 1.5 This is a false statement, therefore it is not part of the solution.
Answer:
9 = 1(7) + 2
So generally it is:
y = x + 2 (I think this is the answer your teacher wants)
Step-by-step explanation:
y = mx + b is the slope intercept form equation
you know that 9 is one of your y points, so you can plug it in (9 = mx + b)
you also know that 7 is an x point, so you can plug it in as well (9 = m(7) + b)
then you can plug in your slope because you know that as well (9 = 1(7) + b)
to find your intercept, subtract your y point from the x point since there is a slope of one (you can only do this for a slope of one) you will get two as your intercept (9 = 1(7) + 2) this is your exact equation with that one point, but to generalize it so you could find any point, you would write: y = x + 2 (you don't include the slope because it is just one)
Hope this helped!
