13m + 3 - 56 = -15m = -36m = -27m = 36
13m - 56 + 15m -36m + 27m - 27m = 36 - 3
-64m = 33
m = 64 + 33
m = 97
emm im not sure
= 3 + 2(2p + 4t)
multiply 2 by parentheses
= 3 + (2*2p) + (2*4t)
= 3 + 4p + 8t
ANSWER: 3 + 4p + 8t is an equivalent expression (remember addition can be done in any order).
Hope this helps! :)
Answer:
-1
Step-by-step explanation:
Answer:
<g = 73°
Step-by-step explanation:
107° + b = 180°
180° - 107° = b
b = 73°
Being that <b and <g are vertical angles, they will have the same angle measurement. Therefore, <g = 73°. (:
Answer:
-3/2
(2x-14)/3
(-2,-6)
Step-by-step explanation:
I solved the first one for you already ( -3/2)
To make a line perpindicular to another line they need to intersect at a 90 degree angle. To do this the slope of the lines have to be the negative reciprical (take the fraction, flip it, and apply a negative sign to it)
If you do this to -3/2 you get 2/3
If we follow our y=mx+b equation from before we (so far) have
2/3x+b=y
which means that we just need to solve for b
We also know that it crosses the point (7,0) which means that if we plug in 7 for x and 0 for y we can solve for b
we have
(2/3)*7+b=0
Solve for B
14/3+b=0
b= -14/3
Which means our equation looks like this
(2x-14)/3
our two equations look like this
(-3/2)x-9
(2x-14)/3
We need to find where their coordinates are the same (where they intersect)
We can do this by setting them equal to each other and then solving for x
we have
(-3/2)x-9=(2x-14)/3
solve for x
-4.5x-27=2x-14
-13= 6.5x
x= -2
Now that we know what x equals we can plug this into any of our two beginning equations
(-3/2)*-2-9=y
3-9=y
-6=y
Which means our coordinates are (-2,-6)
